This coming Tuesday, Microsoft will issue fixes for 33 vulnerabilities in total, including two critical  zero-day flaws relating to Internet Explorer recently discovered that has been used to attack several high-profile targets. Internet Explorer 6, 7, 8, 9 and 10 are the recipients of a patch that can prevent an exploit that enables remote code execution in the browser. This affects all Windows operating systems except XP. The vulnerability ( CVE-​​2013-​​1347 ) had previously been addressed in a workaround yesterday , but given the way it was being exploited with attacks reported on the US Department of Labor and European aerospace and nuclear researchers the patch has been prioritised. A second bulletin deals with another IE vulnerability believed to be one disclosed in March at the annual Pwn2Own hacking competition. At least four of the patches require a restart, Microsoft said. The remaining eight patches will address flaws that range from denial-of-servic

Google has fixed a series of serious vulnerabilities in its Chrome OS , including three high-risk bugs that could be used for code execution on vulnerable machines. Bug bounties is the cash prizes offered by open source communities to anyone who finds key software bugs have been steadily on the rise for several years now. As part of its reward program, Google paid out $31,336 to a researcher who found three of the vulnerabilities . Google's post notes : " We're pleased to reward Ralf-Philipp Weinmann $31,336 under the Chromium Vulnerability Rewards Program for a chain of three bugs, including demo exploit code and very detailed write-up. We are grateful to Ralf for his work to help keep our users safe. " The three-bug chain credited to Weinmann exploited O3D, a JavaScript API (application programming interface) designed for crafting interactive 3-D graphics-based Web applications. The API and supporting browser plug-in were created by Google, with a preliminary ve

The need for vCISO services is growing. SMBs and SMEs are dealing with more third-party risks, tightening regulatory demands and stringent cyber insurance requirements than ever before. However, they often lack the resources and expertise to hire an in-house security executive team. By outsourcing security and compliance leadership to a vCISO, these organizations can more easily obtain cybersecurity expertise specialized for their industry and strengthen their cybersecurity posture. MSPs and MSSPs looking to meet this growing vCISO demand are often faced with the same challenge. The demand for cybersecurity talent far exceeds the supply. This has led to a competitive market where the costs of hiring and retaining skilled professionals can be prohibitive for MSSPs/MSPs as well. The need to maintain expertise of both security and compliance further exacerbates this challenge. Cynomi, the first AI-driven vCISO platform , can help. Cynomi enables you - MSPs, MSSPs and consulting firms

Today Adobe released a patch for two critical vulnerabilities (CVE-2013-0640 and CVE-2013-0641) that are already being exploited by attackers. Adobe released version 11.0.02 of its Adobe Reader and Adobe Acrobat Pro applications.  Vulnerabilities affect Adobe Reader and Acrobat XI (11.0.01 and earlier), X (10.1.5 and earlier) and 9.5.3 and earlier for Windows and Mac OS X systems. " These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system ." security advisory  reads . Exploits were discovered by security company FireEye and researchers with antivirus provider Kaspersky Lab have confirmed the exploit can successfully escape the Adobe sandbox. Users can update the software through the built-in updater or by downloading a copy of the  Windows ,  Mac , or  Linux  installer directly from Adobe's website. 

Microsoft next updates are fully loaded with 57 different security vulnerabilities through 12 separate updates. It will roll out fixes as it always does on Patch Tuesday, the second Tuesday of every month. Anyone who uses Windows as their primary operating system will be quite familiar with Patch Tuesday. According to Microsoft's advisory , The 12 security update including two for Internet Explorer (IE), that will patch a near-record 57 vulnerabilities in the browser, Windows, Office and the enterprise-critical Exchange Server email software. Part of this update will be security patches for every single version of Internet Explorer. Apparently, this is to address a security hole that leaves users open to being exploited through drive-by attacks. Out of the 12 updates, five are considered " critical, " and others are labeled " important, ". As always, the critical patches will automatically install for any Windows users with automatic updates enabled. Two of the

Hacker found a way to hack and change your password like, just he used to change his own password. Confused ? Recently Facebook fix a very critical vulnerability on the tip of ' Sow Ching Shiong ' , an independent vulnerability researcher. Flaw allows anyone to reset the password of any Facebook user without knowing his last password. At Facebook, there is an option for compromised accounts at " https://www.facebook.com/hacked " , where Facebook ask one to change his password for further protection. This compromised account recovery page, will redirect you to another page at " https://www.facebook.com/checkpoint/checkpointme?f=[userid]&r=web_hacked " . Researcher notice that the URL of the page having a parameter called "f" which represents your user ID and replacing the user ID with victim's user ID allow him to get into next page where attacker can reset the password of victim without knowing his last password. The  Vulnera

Some critical vulnerabilities have been reported in Apache Tomcat, which can be exploited by malicious people to bypass certain security restrictions and cause a DoS (Denial of Service) attack. These vulnerabilities affect Apache Tomcat 6.x and Apache Tomcat 7.x . Apache Tomcat vulnerabilities CVE-2012-4534 Apache Tomcat denial of service CVE-2012-3546 Apache Tomcat Bypass of security constraints CVE-2012-4431 Apache Tomcat Bypass of CSRF prevention filter According to CVE-2012-4431 , The CSRF prevention filter could be bypassed if a request was made to a protected resource without a session identifier present in the request.

The Windows 8 and Windows RT security updates will be the first shipped since those operating systems' launch on Oct. 26. The latest vulnerabilities include three critical security vulnerabilities for Windows 8, and one critical security vulnerability for the Surface-based Windows RT operating system. These flaws are considered "critical" and could allow remote code execution on vulnerable systems. Among the various flaws, versions from Windows XP (Service Pack 3) all the way through to Windows 8 are affected, including versions of the Office suite, and versions of Windows Server. Released only in September, Windows Server 2012 requires patching to maintain maximum security. If you've enabled automatic updates, the patches will automatically install on Tuesday. As usual, the specific details about what is being fixed in these updates won't be revealed until the patches themselves are available for download in order to not give hacker groups an advance
