A new Snowden leak, reported by NBC, documents the UK spy agency GCHQ's attacks on Anonymous, which included Denial-of-Service attacks, which are strictly forbidden under UK law. As the Slashdot story notes, "Regular citizens would face 10 years in prison and enormous fines for committing a DoS / DDoS attack. The same applies if they encouraged or assisted in one. But if you work in the government, it seems like you're an exception to the rule."

NBC has published a minimally redacted version [PDF] of the GCHQ slide-deck detailing the agency's illegal hacking attacks on alleged Anonymous participants.

The presentation gives detailed examples of "humint" (human intelligence) collection from hacktivists known by the on-line names G-Zero, Topiary and pOke, as well as a fourth whose name NBC News has redacted to protect the hacker's identity. The hacktivists were contacted by GCHQ agents posing as fellow hackers in internet chat rooms. The presentation includes transcripts of instant message conversations between the agents and the hackers in 2011.

"Anyone here have access to a website with at least 10,000+ unique traffic per day?" asks one hacktivist in a transcript taken from a conversation that began in an Operation Payback chat room. An agent responds and claims to have access to a porn website with 27,000 users per day. "Love it," answers the hacktivist. The hackers ask for access to sites with traffic so they can identify users of the site, secretly take over their computers with malware and then use those computers to mount a DDOS attack against a government or commercial website.

A GCHQ agent then has a second conversation with a hacker known as GZero who claims to "work with" the first hacktivist. GZero sends the agent a series of lines of code that are meant to harvest visitors to the agent's site and make their computers part of a "botnet" operation that will attack other computers.

The "outcome," says the presentation, was "charges, arrest, conviction." GZero is revealed to be a British hacker in his early 20s named Edward Pearson, who was prosecuted and sentenced to 26 months in prison for stealing 8 million identities and information from 200,000 PayPal accounts between Jan. 1, 2010 and Aug. 30, 2011. He and his girlfriend were convicted of using stolen credit card identities to purchase take-out food and hotel stays.
