I hacked Citrix, says Russian hacker

Citrix, a US software company specialising in virtualisation and cloud computing, has reportedly been compromised by a Russian hacker called w0rm.

w0rm is infamous for several attacks over the past five years on a number of high profile targets including the BBC, CNET, Adobe and Bank of America. The identity of the person or group behind w0rm is unknown.

According to a blog post (in Russian), w0rm claims to have been able to gain access to the content management system on the Citrix network via an insecure password. From there, it was able to exploit a series of security holes to gain access to the company's administrative system including the remote assistance system.
