Anonymous victim HBGary goes to ground

The computer security company hacked by members of activist group Anonymous has gone to ground as further revelations about its activites leak online.

HBGary has cancelled its appearances at public events, saying that members of staff had been threatened.

It follows the release of internal documents which appear to show the firm offered to smear Wikileaks' supporters.

HBGary officials said the online messages could have been altered prior to publication.

The company's founder, Greg Hoglund had been scheduled to give a talk at the RSA Security conference in San Francisco this week, but pulled out at the last minute.

The company also withdrew from an associated exhibition.

"In an effort to protect our employees, customers and the RSA Conference community, HBGary has decided to remove our booth and cancel all talks," it said in a statement posted on its website.

According to e-mails that Anonymous claims to have taken from HBGary's servers, the company had proposed a plan to undermine Wikileaks.

At the time, the whistleblowing website was planning to release documents relating to Bank of America.

The leaked emails also suggest that HBGary had discovered evidence that US officials were attempting to monitor visitors to websites affiliated to al Qaeda.

These messages have been posted online via the Anonymous-supported site Anonleaks.ru.

What is Anonymous?

'Anonymous' describes itself as an 'internet gathering'. The term is used to describe a collective of people who come together online, commonly to stage a protest.

The groups vary in size and make-up depending on the cause. Members often identify themselves in web videos by wearing the Guy Fawkes masks popularised by the book and film V for Vendetta.

Its protests often take the form of disrupting websites and services.

Its use of the term Anonymous comes from a series of websites frequented by members, such as the anarchic image board 4Chan.

These allow users to post without having to register or provide a name. As a result, their comments are tagged "Anonymous".

In the past, groups have staged high-profile protests against plans by the Australian government to filter the internet and the Church of Scientology.

Many Anonymous protests tackle issues of free speech and preserving the openness of the net.
