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 ...

Privacy of Internet users is dead somewhere as the Intelligence agencies can watch our every move, hear our every conversation and read our every email and find out anything related to our personal and private life.  Last year, Edward Snowden revealed about the mass surveillance carried out by NSA and other countries intelligence agencies on every citizen of their country. The US Government has allotted a large share of its ' Black Budget ' for secret surveillance programs and to make this happen, NSA has used a number of unethical ways and labelled as legal solutions, harvesting hundreds of millions of Metadata from emails, web activity, chats, social networks, and everything else around the world. The revelations encouraged Internet users think about their privacy and digital rights, and the time came when different organisations started several campaigns to block mass surveillance and fight back against the U.S. National Security Agency ( NSA ). RESET YOU...

Attackers care about ROI – they want to accomplish their objective with the least investment of time and resources possible. The same is true for you - to most effectively manage vulnerabilities, you need to think like an attacker. Ask yourself: How would you go about compromising systems, exfiltrating valuable information and making money? What are the key assets in your network that you would target? How would you get to these assets? Attackers are looking for vulnerabilities that are exposed – ones offering them an easy way to penetrate your network and pivot into the truly valuable assets on your network. Although zero-day exploits are heavily publicized, attackers more often use older, proven exploits very effectively. Fortunately, many such exploits are well known and have clear remediation methods. So, how can you determine if a known vulnerability is actually exploitable? The key is to correlate system vulnerabilities with threat intelligence so you can prioriti...

The development of self own languages has become emblematic of the hot new trend in business as every big Internet service provider is now developing their own and unique programming languages. Two months ago, Facebook released its modern programming language called ' HACK ', which is specially designed to make the process of writing and testing code of complex websites and other software faster, and the company already drives almost all of the its social networking site to HACK over the last year. This Monday, Apple surprises the gathering of people who build software applications for Apple hardware devices at its World Wide Developers Conference (WWDC) by introducing its whole new programming language called Swift , which probably replace Apple's main programming language - Objective-C that is being loved by the developers who build software applications for Apple hardware devices, from iPhone, iPad to Macintosh. The first app built on Swift is the WWDC ap...

GnuTLS, a widely used open source SSL/TLS cryptographic library is vulnerable to a buffer overflow vulnerability that could be exploited to crash TLS clients or potentially execute malicious code on underlying systems. The GnuTLS library implements secure sockets layer (SSL) and transport layer security (TLS) protocols on computers, servers, and softwares to provide encrypted communications over insecure channels. The bug ( CVE-2014-3466 ) was independently discovered by Joonas Kuorilehto of security firm Codenomicon, the same security firm who discovered the biggest Internet vulnerability, Heartbleed. Unlike Heartbleed, the GnuTLS library is not as widely deployed as OpenSSL. The GnuTLS Vulnerability resides in the way GnuTLS parses the session ID from the server response during a TLS handshake. It does not check the length of session ID value in the ServerHello message, which allows a malicious server to send an excessively long value in order to execute buffer overf...
