Cyber criminals have explored one more way to exploit Heartbleed OpenSSL bug against organisations to hijack multiple active web sessions conducted over a virtual private network connection. The consulting and incident response Mandiant investigated targeted attack against an unnamed organization and said the hackers have exploited the " Heartbleed " security vulnerability in OpenSSL running in the client's SSL VPN concentrator to remotely access active sessions of an organization's internal network. The incident is the result of attacks leveraging the OpenSSL Heartbleed vulnerabilities, which resides in the OpenSSL's heartbeat functionality, if enabled would return 64KB of random memory in plaintext to any client or server requesting for a connection. The vulnerability infected almost two-third of internet web servers, including the popular websites. Recently, there has been an arrest of a Canadian teen of stealing usernames, credentials, session IDs and other da

Half of the Internet fall victim to the biggest threat, Heartbleed bug and even the most popular online anonymity network Tor is also not spared from this bug. Tor is one of the best and freely available privacy software, runs on the network of donated servers that lets people communicate anonymously online through a series of nodes that is designed to provide anonymity for users and bypass Internet censorship. When you use the Tor software, your IP address remains hidden and it appears that your connection is coming from the IP address of a Tor exit relay or nodes, which can be anywhere in the world. An Exit relay is the final relay that Tor encrypted traffic passes through before it reaches its destination. But some of these Tor exit nodes are running on the servers with the affected version of OpenSSL installed which are vulnerable to the critical Heartbleed Flaw. This means an attacker can grab the hidden information from the Tor network which is actually restricte

On Saturday, the Senior Administration Officials cast light on the subject of Internet Security and said President Obama has clearly decided that whenever the U.S. Intelligence agency like NSA discovers major vulnerabilities, in most of the situations the agency should reveal them rather than exploiting for national purpose, according to The New York Times . OBAMA's POLICY WITH LOOPHOLE FOR NSA Yet, there is an exception to the above statement, as Mr. President carved a detailed exception to the policy " Unless there is a clear national security or law enforcement need, " which means that the policy creates a loophole for the spying agencies like NSA to sustain their surveillance programs by exploiting security vulnerabilities to create Cyber Weapons. After three-month review of recommendations [ PDF-file ], the Final Report of the Review Group on Intelligence and Communications Technologies was submitted to Mr. Obama on last December, out of which one of the recommendation on pa

Heartbleed has left a worst impression worldwide affecting millions of websites and is also supposed to put millions of Smartphones and tablets users at a great risk. Heartbleed is a critical bug ( CVE-2014-0160 ) in the popular OpenSSL cryptographic software library, that actually resides in the OpenSSL's implementation of the TLS/DTLS heartbeat extension, which allows attackers to read portions of the affected server's memory, potentially revealing users data such as usernames, passwords, and credit card numbers, that the server did not intend to reveal. OpenSSL is a widely-used cryptographic library which implements the SSL and TLS protocol and protects communications on the Internet, and mostly every websites use either SSL or TLS, even the Apache web server that powers almost half of the websites over internet utilizes OpenSSL. But to assume that the users using desktop browsers to visit websites are vulnerable to the Heartbleed bug, will be wrong. Despite 40

The Bloomberg claimed that the U.S. National Security Agency (NSA) knew about the most critical Heartbleed flaw and has been using it on a regular basis to gather " critical intelligence " and sensitive information for at least past two years and decided to keep the bug secret, citing two sources ' familiar with the matter '. In response to the above report, NSA has issued a ' 94 character' statement today denying the claims that it has known about the Heartbleed bug since two years and that it has been using it silently for the purpose of surveillance. " NSA was not aware of the recently identified Heartbleed vulnerability until it was made public ," the U.S. intelligence agency said on its Twitter feed . Heartbleed is one of the biggest Internet vulnerabilities in recent history that left large number of cryptographic keys and private data such as usernames, passwords, and credit card numbers, from the most important sites and services on the Int

We have already read so many articles on Heartbleed, one of the biggest iNternet threat that recently came across by a team of security engineers at Codenomicon , while improving the SafeGuard feature in Codenomicon's Defensics security testing tools.  The story has taken every media attention across the World, as the bug opened doors for the cyber criminals to extract sensitive data from the server's memory and almost every major site have been affected by it. UNINTENTIONAL  BIRTH OF HEARTBLEED More than two years ago, German programmer Robin Seggelmann introduced a new feature called " Heartbeat " in the most secured open source encryption protocol, OpenSSL , which is used by several social networks, search engines, banks and other websites to enable secure connections while transmitting data. But introducing heartbeat feature cost him dearly, as here the most critical bug resides. Dr. Seggelmann allegedly was just trying to improve OpenSSL and wo

Millions of websites, users' passwords, credit card numbers and other personal information may be at risk as a result of the Heartbleed security flaw , a vulnerability in widely used cryptographic library ' OpenSSL '. [ READ DETAILS HERE ] Netcraft survey says that about half a million widely trusted active websites on the internet are vulnerable to the heartbleed bug, which means the information transmitting through hundreds of thousands of websites could be vulnerable, despite the protection offered by encryption techniques. According to Netcraft, " the heartbeat extension was enabled on 17.5% of SSL sites, accounting for around half a million certificates issued by trusted certificate authorities. These certificates are consequently vulnerable to being spoofed (through private key disclosure), allowing an attacker to impersonate the affected websites without raising any browser warnings. " Among the trusted names running OpenSSL is Yahoo!, which has been

Are you safe from the critical bug Heartbleed?? OpenSSL- the encryption technology used by millions of websites to encrypt the communication and is also used to protect our sensitive data such as e-mails, passwords or banking information.  But a tiny, but most critical flaw called " Heartbleed " in the widely used OpenSSL opened doors for the cyber criminals to extract sensitive data from the system memory. WHAT IS HEARTBLEED? SSL and TLS are known to provide communication security and privacy over the Internet for applications such as websites, email, instant messaging (IM), including some virtual private networks (VPNs). Heartbleed is a critical bug ( CVE-2014-0160 ) is in the popular OpenSSL cryptographic software library, that actually resides in the OpenSSL's implementation of the TLS (transport layer security protocols) and DTLS ( Datagram TLS ) heartbeat extension (RFC6520). This bug was independently discovered by a team of security enginee

It is advised to those who are running their web server with OpenSSL 1.0.1 through 1.0, then it is significantly important that you update to OpenSSL 1.0.1g immediately or as soon as possible.  As this afternoon, an extremely critical programming flaw in the OpenSSL has been discovered that apparently exposed the cryptographic keys and private data from some of the most important sites and services on the Internet. The bug was independently discovered by security firm Codenomicon along with a Google Security engineer. The flaw is in the popular OpenSSL cryptographic software library and its weakness allows cyber criminals to steal the information protected, under normal conditions, by the SSL (Secure Sockets Layer) or TLS (Transport Security Layer) encryption used to secure the Internet. OpenSSL is an open-source implementation of the SSL and TLS protocols. The core library implements the basic cryptographic functions that enable SSL and TLS encryption. Mostly every w
