Bit9 Defends Response To Hack, Promises More Details

The security firm Bit9 defended its response to a hack of its own network last week and promised to release more information to the public about what happened – just not quite yet. In a blog post dated Saturday, February 9, the company’s CTO, Harry Sverdlove, said that the company responded promptly to the attack and contacted customers as soon as it completed its own investigation of the hack, which allowed unknown assailants to sign malicious programs using a Bit9 code signing server. That malware was subsequently released on networks of Bit9 customers. Sverdlove said the company’s¬†“first and foremost priority was to inform our customers quickly and directly,” and that the company did so “as soon as we understood and had mitigated the attack, and we were able to provide actionable advice.” The blog post by Sverdlove, just a day after a post by Bit9 CEO Patrick Morley that disclosed […]

Researchers: Hole In TLS Encryption Could Expose Secure Web Sessions

Researchers at the University of London are going public with a paper that claims to have found a flaw in the specification for Transport Layer Security (TLS) that could leave supposedly secure Web, IM, VoIP and other online sessions exposed to prying eyes. The researchers, Nadhem Al Fardan and Kenny Patterson of the Information Security Group at Royal Holloway, University of London said that the security hole stem from a flaw in the TLS specification, rather than a bug in how TLS is implemented. The two researchers have developed proof of concept attacks that take advantage of the flaw, and that could be used to recover a complete block of TLS-encrypted plaintext, the researchers said. Al Fardan is a Ph.D student in the Information Security Group. Patterson is a professor of Information Security there. The two have ¬†discovered other, serious holes in TLS before. Notably: the two discovered a critical […]
