100,000 websites destroyed by hackers

by Hilbert Hagedoorn on: 06/10/2009 08:59 AM | source: | 0 comment(s)

As many as 100,000 websites where destroyed by attackers who targeted a zero-day vulnerability in a widely-used virtualization application.

Technicians at UK-based Vaserv.com were still scrambling to recover data on Monday evening UK time, more than 24 hours after unknown hackers were able to gain root access to the company's system, Rus Foster, the company's director told The Register. He said the attackers were able to penetrate his servers by exploiting a critical vulnerability in HyperVM, a virtualization application made by a company called LXLabs.

"We were hit by a zero-day exploit" in version 2.0.7992 of the application, he said. "I've heard from other people they've been hit by the same thing."

Foster said he's been unable to reach anyone at LXLabs to discuss the suspected vulnerability. The Register has also received no response to inquiries sent to the company, which according to its website is located in Bangalore.

According to Foster, data for about half of the websites hosted on Vaserv was destroyed all at once sometime Sunday evening, shortly after administrators noticed "strangeness" on the system. The attackers had the ability to execute sensitive Unix commands on the system, including "rm -rf," which forces a recursive delete of all files.

Some 50 percent of Vaserv's customers signed up for unmanaged service, which doesn't include data backup, Foster said. It remains unclear of those website owners will ever be able to retrieve their lost data, he said. As a result, at least half the websites that were hosted on the site remain offline.

"Since last night, I've had probably 40 phone calls from clients saying 'Why is my website down,'" said Daniel Voyce, a web developer for Nu Order Webs who uses Vaserv to host customer sites. "It's making me look bad."

Voyce said the hackers, given the high level of server access they gained, were likely able to intercept a wealth of sensitive data stored on Vaserv's servers. Voyce said his customers are safe because all sensitive information was encrypted [via the register].
