The anonymous hacker who claims to be behind the Gamma Group hack and the leak of 40GB of files – which are related to the company’s activities and the “FinFisher” monitoring suite – has published a hacking guide for other hacktivists.
"I'm not writing to brag about how 31337 h4x0r I am or what crazy skills it took to figure out Gamma," the hacker wrote, warning, however, that unauthorized access to third-party networks is illegal.
"I write to demystify hacking, to show how simple it is, to inform and inspire you to get out there and hack shit. If you have no experience with programming or hacking, the following text may seem like a foreign language to you.".
The do-it-yourself guide published by the anonymous man explains how hackers can map entryways into a target's network, search for vulnerable services, and exploit any weaknesses they find.
The guide also lists some of the most common methods hackers use to hide their IP addresses and digital fingerprints. Among other things, the guide suggests installing Whonix on a hidden and encrypted volume created using TrueCrypt and performing all operations from there. It also advises hackers not to use the Tor network for their activities, but hacked servers, which is also illegal.
So far it does not appear to have been confirmed that the author is in any way related to the attack against Gamma Group.
