Multiple flaws have been identified in Linux Kernel and related software could allow hackers to hack your Linux machines, shared hosting and websites hosted on them. PRIVILEGE ESCALATION VULNERABILITY IN LINUX KERNEL A privilege escalation vulnerability has been identified in the widely used Linux kernel that could allow an attackers to take the control of users' system. On Thursday, the most popular distributor of open source Linux OS, Debian warned about this vulnerability (CVE-2014-3153) in a security update, along with some other vulnerabilities in the Linux kernel that may lead to a denial of service attack. The most critical one is the flaw (CVE-2014-3153) discovered by Pinkie Pie which resides in the futex subsystem call of Linux Kernel 2.6.32.62/3.2.59/3.4.91/3.10.41/3.12.21/3.14.5 versions , leaving a queued kernel waiter on the stack, which can be exploited to potentially execute arbitrary code with kernel mode privileges.

Ransomware is an emerging threat in the evolution of cybercriminals techniques to part you from your money. Typically, the malicious software either lock victim's computer system or encrypt the documents and files on it, in order to extort money from the victims. Though earlier we saw the samples of Ransomware tended to be simple with dogged determinations to extort money from victims. But with the exponential rise in the samples of Ransomware malwares, the recent ones are more subtle in design, including Cryptolocker , Icepole , PrisonLocker , CryptoDefense and its variants. Now, the ransomware dubbed as Crytowall , a latest variant of the infamous ransomware Cryptolocker is targeting users by forcing them to download the malicious software by through advertising on the high profile domains belonging to Disney, Facebook, The Guardian newspaper and others. Cryptolocker is designed by the same malware developer who created the sophisticated CryptoDefense ( Trojan.Crypt...

Vodafone , the world's second-largest mobile carrier with more than 400 million customers around the world has issued its first " Law Enforcement Disclosure Report ", reveals that the governments in some of the countries it operates, have direct access to its network allowing them to listen to all conversations. The Company has broken its silence on government surveillance and after Snowden's revelations about NSA , this is the only most comprehensive transparency report ever published by an International company detailing that how some Governments are taking advantage of their laws to infiltrate citizens privacy. Vodafone operates in 29 countries, where the government agencies need legal notices to tap into customers' communications, but some of those countries are actually tapping directly into their network, without any need for a warrant or any explanation. There are many countries like Albania, Egypt, Hungary, India , Malta, Qatar, Romania, South Africa and Turk...

Today Microsoft has released its Advance Notification for the month of June 2014 Patch Tuesday releasing seven security Bulletins, which will address several vulnerabilities in its products, out of which two are marked critical and rest are important in severity. This Tuesday, Microsoft will issue Security Updates to address seven major vulnerabilities and all those are important for you to patch, as the flaws are affecting various Microsoft software, including Microsoft Word, Microsoft Office and Internet Explorer. CRITICAL VULNERABILITY THAT YOU MUST PATCH Bulletin one is considered to be the most critical one, which will address a the zero-day Remote Code Execution vulnerability, affecting all versions of Internet Explorer, including IE11 in Windows 8.1.  All server versions of Windows are affected by this vulnerability, but at low level of severity because by default, Internet Explorer runs in Enhanced Security Configuration and just because Server Core ver...

Remember OpenSSL Heartbleed vulnerability ? Several weeks ago, the exposure of this security bug chilled the Internet, revealed that millions of websites were vulnerable to a flaw in the OpenSSL code which they used to encrypt their communications. Now once again the OpenSSL Foundation has issued software updates to patch six new vulnerabilities, and two of them are critical. MAN-IN-THE-MIDDLE ATTACK (CVE-2014-0224) First critical vulnerability (CVE-2014-0224) in OpenSSL is " CCS Injection " - resides in ChangeCipherSpec (CCS) request sent during the handshake that could allow an attacker to perform a man-in-the-middle attack against the encrypted connection servers and clients.  By exploiting this vulnerability an attacker could intercept an encrypted connection which allows him to decrypt, read or manipulate the data. But the reported flaw is exploitable only if both server and client are vulnerable to this issue. According to the OpenSSL advisory , " An attacker...

We have seen cybercriminals targeting PCs with Ransomware malware that encrypts your files or lock down your computer and ask for a ransom amount to be paid in a specified duration of time to unlock it. To deliver the Ransomware malwares to the mobile devices, cyber criminals have already started creating malicious software programs for android devices. Last month, we reported about a new Police Ransomware malware that locks up the devices until the victims pay a ransom to get the keys to unlock the phone. But, the malware just lock the mobile screen and a loophole in the its implementation allowed users to recover their device and data stored on SDcard. Now, in an effort to overcome this, threat actors have adopted encryption in the development of mobile Ransomware malwares. Recently, the security firm ESET has discovered a new Android ransomware, dubbed as Android/Simplocker.A , that has ability to encrypt the files on the device SD card and then demand a ransom from the victim ...
