GoKawiilOver the last few decades, several mysterious hackers have captured the public’s imagination, but none quite like Phineas Fisher. A decade after their most famous hack, Phineas remains, by most accounts, the most prolific and public hacker never to have been caught.
As part of our series on the biggest cybersecurity mysteries of all time, we’re delving into the enigma of Phineas, the hacktivist who hacked controversial spyware makers FinFisher and Hacking Team. The latter, an Italian startup, was among the first to turn government spyware into a viable global business, paving the way for spyware makers such as the Israeli NSO Group. Phineas’ hack against Hacking Team eventually led to the startup’s demise years later.
Apart from Anonymous, an amorphous amalgam of hacktivists with a mixed track record of mostly stunt hacks designed to gather publicity rather than have real impact, Phineas is perhaps the most well-known hacktivist in history. Their story is made of impressive hacks and endless unanswered questions.
Who is Phineas Fisher?
Variously called an anarchist, a cybercriminal, a hacktivist, and a vigilante, the hacker has said they “use a lot of different names” for different hacking escapades.
The hacks we know about were big enough to turn Phineas into a legend among hackers. “I would like to meet Phineas Fisher so that I could buy them a seven-course, three-Michelin-star dinner somewhere and listen to them explain how they turned Hacking Team inside out like a gym sock,” a well-known security researcher once wrote on Twitter. There’s even a song about them.
Phineas first emerged in August 2014, when they announced they had hacked Gamma Group, the makers of the FinFisher spyware — which is where the nickname comes from. They publicized the hack via a Twitter account cheekily called @GammaGroupPR, leaking stolen data including mobile spyware, product manuals, and a price list. The damage was limited, and FinFisher carried on. Phineas published a post-mortem that doubled as a leftist manifesto, then vanished.
A year later, they came back with a bang, hacking Hacking Team, another spyware maker. They took practically everything: more than 400 gigabytes including source code, tens of thousands of internal emails, confidential contracts, and customer lists. The leak allowed journalists to reveal scandals in Ecuador, Mexico, and Panama. Years later, Hacking Team’s CEO David Vincenzetti was forced to sell his company for one euro. For some former employees, Phineas’ hack was the beginning of the end.
Phineas went on to hack the union of the Mossos d’Esquadra, which is the police force of Catalonia, publishing a post-mortem and a 39-minute tutorial video — consistent with their stated anti-police ideals. Their next victim was the ruling party of Turkey’s authoritarian president Recep Tayyip Erdoğan, a hack motivated by solidarity with Rojava, a leftist autonomous region in northern and eastern Syria that Turkey was fighting against.
Phineas’ last known victim was Cayman National Bank’s branch in the Isle of Man, a self-governing island between England and Ireland. The hack hinted at a different side of Phineas. “I look for illegal ways to make money in order to free my time so I can do something useful with it. Once I had that figured out, I started scaling it up and making more money than I need and giving the extra away,” Phineas said in an interview with activist Freddy Martinez. (Phineas donated at least $10,000 in Bitcoin to Rojava.)
