More than two years after the disclosure of the HeartBleed bug, 200,000 services are still affected. Systems susceptible to Heartbleed attacks are still too many, despite the flaw was discovered in 2014 nearly 200,000 systems are still affected. Shodan made a similar search in November 2015 when he found 238,000 results, the number dropped to 237,539 […]

Researchers devised a method to unmask malware’s use of TLS without decrypting the data flow. The technique relies on analysis of observable data features. A team of security experts from Cisco demonstrated that it is possible to detect a malware in TLS connections without decrypting the traffic and block it. The researchers Blake Anderson, Subharthi Paul […]

According to the security firm High-Tech Bridge many of the Alexa Top 10,000 websites are still vulnerable to the OpenSSL flaw CVE-2016-2107. The CVE-2016-2107 flaw affecting the open-source cryptographic library could be exploited to launch a man-in-the-middle attack leveraging on the ‘Padding Oracle Attack’ that can decrypt HTTPS traffic if the connection uses AES-CBC cipher and the server supports AES-NI. According […]

Bar Mitzvah is the name of a new attack on RC4-Based SSL/TLS encryption that allows disclosure of sensitive data by exploiting a 13-Year-Old Vulnerability. Both Secure Sockets Layer (SSL) and its successor Transport Layer Security (TLS) cryptographic protocols rely on the Rivest Cipher 4 (RC4) algorithm to encrypt data transfers. The problem is that the […]
