Heartbleed Used To Bypass 2-Factor Authentication, Hijack User Sessions
wiredmikey (1824622) writes "Security nightmares sparked by the Heartbleed OpenSSL vulnerability continue. According to Mandiant, now a unit of FireEye, an attacker was able to leverage the Heartbleed vulnerability against the VPN appliance of a customer and hijack multiple active user sessions. The attack bypassed both the organization's multifactor authentication and the VPN client software used to validate that systems connecting to the VPN were owned by the organization and running specific security software.
"Specifically, the attacker repeatedly sent malformed heartbeat requests to the HTTPS web server running on the VPN device, which was compiled with a vulnerable version of OpenSSL, to obtain active session tokens for currently authenticated users," Mandiant's Christopher Glyer explained. "With an active session token, the attacker successfully hijacked multiple active user sessions and convinced the VPN concentrator that he/she was legitimately authenticated."
After connecting to the VPN, the attacker attempted to move laterally and escalate his/her privileges within the victim organization, Mandiant said." -
Security Firm Mandiant Says China's Army Runs Hacking Group APT1
judgecorp writes "The Chinese government has been accused of backing the APT1 hacking group, which appears to be part of the Chinese People's Liberation Army (PLA), according to the security firm which worked with the New York Times when it fell victim to an attack. The firm, Mandiant, says that APT1 is government sponsored, and seems to operate from the same location as PLA Unit 61398." Unsurprisingly, this claim is denied by Chinese officials.

Cleaning Up the Mess After a Major Hack Attack
Hugh Pickens writes "Kevin Mandia has spent his entire career cleaning up problems much like the recent breach at Stratfor where Anonymous defaced Stratfor's Web site, published over 50,000 of its customers' credit card numbers online and have threatened to release a trove of 3.3 million e-mails, putting Stratfor is in the position of trying to recover from a potentially devastating attack without knowing whether the worst is over. Mandia, who has responded to breaches, extortion attacks and economic espionage campaigns at 22 companies in the Fortune 100 in the last two years and has told Congress that if an advanced attacker targets your company then a breach is inevitable (PDF), calls the first hour he spends with companies 'upchuck hour' as he asks for firewall logs, web logs, and emails to quickly determine the 'fingerprint' of the intrusion and its scope. The first thing a forensics team will do is try to get the hackers off the company's network, which entails simultaneously plugging any security holes, removing any back doors into the company's network that the intruders might have installed, and changing all the company's passwords. 'This is something most people fail at. It's like removing cancer. You have to remove it all at once. If you only remove the cancer in your leg, but you have it in your arm, you might as well have not had the operation on your leg.' In the case of Stratfor, hackers have taken to Twitter to announce that they plan to release more Stratfor data over the next several days, offering a ray of hope — experts say the most dangerous breaches are the quiet ones that leave no trace."
