A number of TLS software implementations contain vulnerabilities that allow hackers with minimal computational expense to learn RSA keys. Florian Weimer, a researcher with Red Hat, last week published a paper called
Two researchers with the University of Leuven have developed a new, more practical attack technique that exposes weaknesses in the RC4 encryption algorithm.
Almost a third of the world's encrypted Web connections can be cracked using an exploit that's growing increasingly practical, computer scientists warned Wednesday. They said the attack technique on a cryptographic cipher known as RC4 can also be used to break into wireless networks protected by the Wi-Fi Protected Access Temporal Key Integrity Protocol.
Organizations that installed the June 11 OpenSSL update need to pull it back immediately after a serious certificate validation error was discovered and patched today in a new update.
