A pseudonymous hacker who claimed responsibility for the Hacking Team and Gamma Group breaches, has released a tutorial video showcasing various hacking techniques, which targeted Spain's Catalan (Sindicat De Mossos d'Esquadra) police union.

The hacker, going by the name Phineas Fisher (aka Hack Back, Gamma GroupPR) hacked into the Sindicat De Mossos d'Esquadra (SME) website and proceeded to dump all the data, including names, bank details and additional personal details of the police officers, online. However, the data was later removed. The hacker also claimed to have temporarily vandalised the SME's Twitter account.

The roughly 40-minute-long video displays Fisher using the popular Kali Linux operating system, which comes bundled with various penetration testing features. He provides viewers with a step-by-step guided process on how to go about determining whether a website is vulnerable to a particular strain of an SQL injection and then proceeds to attack the website and download the data accessed.

Fisher also highlights the date of the hack in the video, remarking, "so it's likely the majority of Mossos were literally out on the streets at that moment harassing protestors out for Global Debout and the anniversary of 15M", the Motherboard reported.

This is not the first time Fisher has released a hacking guide. In April he published a detailed DIY guide on how he broke into the Hacking Team servers and proceeded to ransack their sensitive data. "You used to have to sneak into offices to leak documents. You used to need a gun to rob a bank. Now you can do both from bed with a laptop in your hand," Fisher wrote in the guide.

Fisher also recently revealed having donated stolen Bitcoins to a economy-building community project in Rojava, located in the Kudish region of Syria. He claims to have gained access to the funds donated by pulling off a cyberheist on an unnamed bank, alluding to more such attacks in the future.
