itwbennett writes: HBGary Federal cancelled a talk the company's CEO Aaron Barr was planning to give at the BSides San Francisco conference on his investigation of WikiLeaks. 'I was receiving death threats,' Barr said in an interview Tuesday. 'There was lots of talk that was being made of in the Anonymous IRC channels of harassing us at our booth and sending people to heckle [HBGary speakers at the conference].' The company has also decided to pull its booth from the RSA Conference floor after it was vandalized on Sunday, said Jim Butterworth, HBGary's vice president of services. 'We... came back the next morning and it was very apparent that the group responsible for the activities in the news had decided to make another statement,' he said.
