March 06, 2019Mohit Kumar
You must update your Google Chrome immediately to the latest version of the web browsing application. Security researcher Clement Lecigne of Google's Threat Analysis Group discovered and reported a high severity vulnerability in Chrome late last month that could allow remote attackers to execute arbitrary code and take full control of the computers. The vulnerability, assigned as CVE-2019-5786 , affects the web browsing software for all major operating systems including Microsoft Windows, Apple macOS, and Linux. Without revealing technical details of the vulnerability, the Chrome security team only says the issue is a use-after-free vulnerability in the FileReader component of the Chrome browser, which leads to remote code execution attacks. What's more worrisome? Google warned that this zero-day RCE vulnerability is actively being exploited in the wild by attackers to target Chrome users. "Access to bug details and links may be kept restricted until a majo

Google's Chrome web browser Extensions are under attack with a series of developers being hacked within last one month. Almost two weeks ago, we reported how unknown attackers managed to compromise the Chrome Web Store account of a developer team and hijacked Copyfish extension , and then modified it to distribute spam correspondence to users. Just two days after that incident, some unknown attackers then hijacked another popular extension ' Web Developer ' and then updated it to directly inject advertisements into the web browser of over its 1 million users. After Chris Pederick, the creator of 'Web Developer' Chrome extension that offers various web development tools to its users, reported to Proofpoint that his extension had been compromised, the security vendor analysed the issue and found further add-ons in the Chrome Store that had also been altered. According to the latest report published by the researchers at Proofpoint on Monday, the expanded

Phishers have recently hacked an extension for Google Chrome after compromising the Chrome Web Store account of German developer team a9t9 software and abused to distribute spam messages to unsuspecting users. Dubbed Copyfish, the extension allows users to extract text from images, PDF documents and video, and has more than 37,500 users. Unfortunately, the Chrome extension of Copyfish has been hijacked and compromised by some unknown attacker, who equipped the extension with advertisement injection capabilities. However, its Firefox counterpart was not affected by the attack. The attackers even moved the extension to their developer account, preventing its developers from removing the infected extension from the store, even after being spotted that the extension has been compromised. "So far, the update looks like standard adware hack, but, as we still have no control over Copyfish, the thieves might update the extension another time… until we get it back," the de

Feross Aboukhadijeh , 22-year-old Web developer from Stanford has discovered  HTML5 browser exploit can flood your Hard Drive with Cat and Dogs i.e junk data. Many times a website needs to leave a little data i.e 5-10KB on your computer like a cookie, but HTML5 allow sites to store larger amounts of data (like 5-10 MB). In a proof-of-concept he was able to full up 1 GB of HDD space every 16 seconds. He created FillDisk.com in order to demonstrate the exploit in HTML5. Once user will visit the website the Web Storage standard allows website to place large amounts of data on your drive. Please note that, It's not a hack and this exploit won't allow attackers to access your computer. However, Web browsers have the ability to limit just how much space websites can dump onto your hard drive. Firefox's implementation of HTML5 local storage is not vulnerable to this exploit. Whereas Chrome, Safari (iOS and desktop), and IE vulnerable to this. You can fin

Chrome 23 Released, 14 vulnerabilities patched

November 06, 2012Mohit Kumar
Google today released Chrome version 23 to the Stable Channel. 23.0.1271.64 for Windows, Mac, Linux, and Chrome Frame. Update includes patch for 12 vulnerabilities in the Windows version and two vulnerabilities in Mac OS X version. Chrome 23 is the support of the Do Not Track (DNT) protocol, number of new features including GPU accelerated video decoding on Windows and easier website permissions. " We recently enabled GPU-accelerated video decoding for Chrome on Windows. Dedicated graphics chips draw far less power than a computer's CPU, so using GPU-accelerated video decoding while watching videos can increase battery life significantly ." Out of  14 vulnerabilities , 6 vulnerabilities rated as high and rest are of either medium or low severity. CVE number of all bugs are - CVE-2012-5128, CVE-2012-5126, CVE-2012-5125, CVE-2012-5124, CVE-2012-5123, CVE-2012-5115, CVE-2012-5127, CVE-2012-5120, CVE-2012-5116, CVE-2012-5118, CVE-2012-5121, CVE-2012-5117,CVE-2012-5119, CVE-2

Hacker known as " Pinkie Pie " produced the first Chrome vulnerability at the Hack In the Box conference on Wednesday, just ahead of the deadline for the competition this afternoon. The exploit, if later confirmed by Google’s US headquarters, will have earned the teenage hacker known as Pinkie Pie the top US$60,000 cash reward. In March, Pinkie Pie and Sergey Glazunov both won $60,000 for their exploits at the first Pwnium competition. Google established the Pwnium competition as an alternative to the Pwn2own contest in order to add the requirement that participants provide details of their exploit. Google will give away up to a total of US$2 million during the event. $60,000 - “Full Chrome exploit”: Chrome / Win7 local OS user account persistence using only bugs in Chrome itself. $40,000 - “Partial Chrome exploit”: Chrome / Win7 local OS user account persistence using at least one bug in Chrome itself, plus other bugs. For example, a WebKit bug combined with a Windows
