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 […]

Friday Night Massacre: Twitter Hacked, Info on 250k Exposed
What better time to drop some really bad and embarrassing news than late on a Friday afternoon, as everyone is heading out the door? So it was with social media giant Twitter, which dropped a bombshell late Friday: revealing that it had been compromised in an “extremely sophisticated” attack that yielded the account credentials for around 250,000 users. A blog post by Twitter Security Team member Bob Lord on Friday said that the company has been investigating the breach all week long, after detecting unusual patterns of account access across its network. After stopping an attack that was in progress, the company’s investigation revealed that the attackers “may have had access to limited user information – usernames, email addresses, session tokens and encrypted/saltedversions of passwords – for approximately 250,000 users,” Lord wrote. Twitter did not discuss the circumstances of the breach, but reiterated guidance from the U.S. Department of Homeland Security for users to disable Java […]
New York Times Hack Puts Antivirus on Defensive
The big news this morning is the New York Times’ scoop on…well…itself. According to a report in today’s paper, the Times’s computer network was compromised for more than four months by attackers believed to be located in China. The attacks followed a Times exposé on the wealth accumulated by family members of China’s prime minister, Wen Jiabao – one of a series of reports in Western media outlets that raised questions about corruption and influence peddling in China’s ruling Communist Party. Attackers planted 45 pieces of information-stealing malware on Times systems, despite the presence of antivirus software from Symantec Corp. protecting those systems before, during and after the hack. The story is fueling debate about the value of anti-virus software and prompted Symantec to issue a statement defending its technology, but warning that signature-based antivirus is not enough to stop sophisticated attacks. According to the Times report, the attacks used compromised systems on […]
School Shooters May Tip Their Hand In Facebook Rants
School shootings have occurred with sickening regularity in the United States in the last decade. The shootings happen in all types of communities, while the shooters come from all different backgrounds. But almost all of them have one thing in common: they used social media to vent their anger and, often, declare their murderous intentions ahead of time. An analysis of common trends in school shootings by the New Jersey Fusion Center said social media sites like Facebook are a common element in the majority of school shootings, with students who have conducted or planned attacks against their schools publicizing their anger and or intentions on sites like Facebook. The “Situational Awareness Report” (PDF) on “School Shooting Commonalities” is dated November 15, 2012, predating the horrific shooting at Sandy Hook Elementary School in Newtown, Connecticut that killed 26. In that case, the shooter, Adam Lanza, was described as a loner who spent hours […]
Pi Million Dollars! Google Sets $3.14 Million Pot For Pwnium 3 Contest
Google cemented its reputation as the squarest company around Monday (pun intended), offering prizes totaling Pi Million Dollars – that’s right: $3.14159 million greenbacks – in its third annual Pwnium hacking contest, to be held at the CanSecWest conference on March 7 in Vancouver, British Columbia. Google will pay $110,000 for a browser or system level compromise delivered via a web page to a Chrome user in guest mode or logged in. The company will pay $150,000 for any compromise that delivers “device persistence” delivered via a web page, the company announced on the chromium blog. “We believe these larger rewards reflect the additional challenge involved with tackling the security defenses of Chrome OS, compared to traditional operating systems,” wrote Chris Evans of Google’s Security Team. The announcement is part of stepped up efforts by the Mountain View company to put a premium on information about security holes affecting its products, […]
