BlueScreenView scans all your minidump files created during 'blue screen of death' crashes, and displays the information about all crashes in one table. For each crash, BlueScreenView displays the minidump filename, the date/time of the crash, the basic crash information displayed in the blue screen (Bug Check Code and 4 parameters), and the details of the driver or module that possibly caused the crash (filename, product name, file description, and file version). Features Automatically scans your current minidump folder and displays the list of all crash dumps, including crash dump date/time and crash details. Allows you to view a blue screen which is very similar to the one that Windows displayed during the crash. BlueScreenView enumerates the memory addresses inside the stack of the crash, and find all drivers/modules that might be involved in the crash. BlueScreenView also allows you to work with another instance of Windows, simply by choosing the right minidump folder (In Advanced Options). BlueScreenView automatically locate the drivers appeared in the crash dump, and extract their version resource information, including product name, file version, company, and file description. For those who use Windows at a daily basis I suggest to take a closer look at the NirSoft Suite. Useful for many things, including security. Source: HERE

If you're currently on a Mac computer and using a Chrome browser then a weird little Apple's OS X quirk, just a special thirteen-characters string could cause your tab in Chrome to crash instantly. A string of 13 characters (appear to be in Assyrian), shown below in an image, is all needed to crash any tab in Chrome for OS X, however, this text has no impact on Windows, Android, or iOS operating systems. This Chrome crash vulnerability has already been reported by an open-source project Chromium project, which means that Google is likely aware of this troublesome issue. What steps will reproduce the problem? Any page with [that special character] will crash the chrome tab on a Mac. Just create any dummy page with the unicode characters, and the Mac Chrome tab will crash hard. What is the expected result? Expect it not to crash What happens instead? It crashes Warning: Do not click on this link, which actually points to the bug report on the Chromium product describing the issue, if your are using Chrome on a Mac. If you’ll click, it will immediately cause the Chrome tab to crash in which the link opens. Emil Protalinski of VentureBeat says even the tab showing the news article also crashes for some readers. The issue appears to be small but is really serious, as it is possible for anyone to tweet out the text in question, and crash all Chrome for Mac users whose Twitter timeline will load those characters. The developer who discovered this bug gives two different scenarios in which this bug could be abused. "This is pretty serious. You could imagine someone spamming this message in Hangouts/Gmail and just straight-up force crashing all Mac Chrome browsers," the developer said. Furthermore, someone could post this 13-characters string on Facebook walls or timelines, and force-crash all Mac Chrome browsers that will saw the characters in question. VentureBeat notes that the Chrome crash doesn't happen every time, in some cases, when Chrome renders text differently, Mac users see 13 blank rectangles (????? ??? ?????) instead of the crash, though they never see the proper characters. It's currently not known why this character causes tab on Chrome to crash while page rendering, but we'll recommend you to do not use theses characters while Tweeting or dropping them in the comments or emailing them to the entire company or posting them to Facebook or as a headline of your blog post. If you are curious just how often and why your Chrome is crashing, you can type chrome://crashes into your location bar and press Enter to view the list of crashes. Source

A Vulnerability has been discovered in the wildly popular messaging app WhatsApp, which allows anyone to remotely crash WhatsApp just by sending a specially crafted message, two security researchers reported ‘The Hacker News’. Two India based independent security researchers, Indrajeet Bhuyan and Saurav Kar, both 17-year old teenagers demonstrated the WhatsApp Message Handler vulnerability to one of our security analyst. In a video demonstration, they showed that by sending a 2000 words (2kb in size) message in special character set can crash the receiver's app. The worried impact of the vulnerability is that the user who received the specially crafted message will have to delete his/her whole conversation and start a fresh chat, because opening the message keeps on crashing WhatsApp unless the chat is deleted completely. "What makes it more serious is that one needs to delete entire chat with the person they are chatting to in order to get back whatsapp work in normal," Bhuyan told THN in an e-mail. According to the duo, the reported vulnerability has been tested and successfully works on most of the versions of Android Operating system including Jellybean, Kitkat, and all the below android versions. Similarly, Any member of your WhatsApp group could intentionally send a specially crafted message to exit people from the group and delete the group. Also, for example, if I don’t want someone to keep records of my chat with them, then I can also send the same message exploit to the person. The vulnerability has not been tested on iOS, but it is sure that all versions of WhatsApp including 2.11.431 and 2.11.432 are affected with this bug. Also the attack does not work on Windows 8.1. They have also provided the Proof-of-Concept (PoC) video for the attack, users can watch above. WhatsApp, bought by Facebook for $19 billion in February this year, has 600 Million users as of October 2014, and according to the researchers, an estimated number of users affected by the vulnerability could be 500 Million. WhatsApp was in news recently for making end-to-end encryption on all text messages as a default feature in an effort to boost the online privacy and security of its users around the world. The app maker describe this move as the "largest deployment of end-to-end encryption ever." Video --> Source
