Permanent Reverse TCP Backdoor for IPhone and IPad

Security Expert from Coresec explains the use of a Permanent Reverse TCP Backdoor "sbd-1.36" for IPhone and IPad developed by Michel Blomgren. sbd is a Netcat-clone, designed to be portable and offer strong encryption. It runs on Unix-like operating systems and on Microsoft Win32. sbd features...

HTTPS: block-wise chosen-plaintext attack against SSL/TLS (BEAST)

The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HT...

Mandriva Linux Security Advisory : curl (MDVSA-2012:058)

Multiple vulnerabilities has been found and corrected in curl : curl is vulnerable to a SSL CBC IV vulnerability when built to use OpenSSL for the SSL/TLS layer. A work-around has been added to mitigate the problem CVE-2011-3389. curl is vulnerable to a data injection attack for certain protocols...

SSL/TLS Protocol Initialization Vector Implementation Information Disclosure Vulnerability (BEAST)

A vulnerability exists in SSL 3.0 and TLS 1.0 that could allow information disclosure if an attacker intercepts encrypted traffic served from an affected system. TLS 1.1, TLS 1.2, and all cipher suites that do not use CBC mode are not affected. This plugin tries to establish an SSL/TLS remote...
