Phineas Fisher said an undisclosed zero-day vulnerability gave him an initial foothold in Hacking Team’s network. He claimed he then gained administrative access, captured an administrator’s credentials, and used them to reach the company’s source-code network. That sequence comes from Fisher’s account, reported by VICE in 2016; it was not independently verified as a forensic reconstruction.
Who hacked Hacking Team?
Hacking Team, an Italian company that sold surveillance and hacking tools to police and intelligence agencies, was breached in 2015. The person who claimed responsibility used the name Phineas Fisher. In April 2016, journalist Lorenzo Franceschi-Bicchierai reported Fisher’s account of how the intrusion unfolded.
Fisher framed the attack as political action against a surveillance vendor. In an email quoted by VICE, Fisher said, “I would characterize myself as an anarchist revolutionary, not as a vigilante,” and added, “I’m clearly a criminal, it’s unclear whether Hacking Team did anything illegal.” Those are Fisher’s characterizations, not a legal determination about the company or the breach.

How did Fisher say he got into Hacking Team?
Fisher’s explanation, as reported by VICE, describes a chain of access rather than a single action. The exact zero-day vulnerability and its location were not disclosed, and the reported technical sequence was not independently confirmed by a public forensic account.

- Initial foothold: Fisher said an undisclosed zero-day vulnerability let him enter the network. VICE reported that the vulnerability was still unpatched at the time of the article, but Fisher withheld the details. This is not evidence that the vulnerability remains usable today.
- Movement within the network: Fisher said he moved through the network and obtained administrative privileges in the main Windows network.
- Administrator credentials: Fisher said he monitored system administrators and captured administrator Christian Pozzi’s passwords by recording keystrokes.
- Access to source code: Fisher said the source code was held on a separate network and that the captured credentials enabled him to access it.
- Company Twitter account: Fisher said he reset the account password using its account-recovery function, then used Hacking Team’s account to announce the breach.
These are claims attributed to Fisher, not a verified incident-response timeline. VICE said it could not verify every detail because neither Hacking Team nor Italian authorities had released a full account. Hacking Team spokesperson Eric Rabe referred requests for comment to the Italian police authorities investigating the attack. VICE/Motherboard, April 15, 2016
How long was the attacker inside?
Fisher said the attacker was in Hacking Team’s network for six weeks and spent roughly 100 hours moving through it and collecting data. Both figures are self-reported; they should not be treated as independently measured duration or labor totals. Fisher also described the disparity between the effort and the damage this way: “That’s the beauty and asymmetry of hacking: with just 100 hours of work, one person can undo years of a multimillion dollar company’s work.”

What did the Hacking Team leak reveal?
In early July 2015, a large collection of company files appeared online, and Hacking Team’s Twitter account was taken over to announce the breach. The leaked material reportedly included internal documents, emails, customer information, and source code. VICE’s account of the breach
The materials also drew attention to the company’s government customers and communications. A 2021 article in the UCLA Journal of International Law and Foreign Affairs discusses leaked communications and contracts in the context of the evidentiary value and ethical complications of unlawfully obtained digital material. A leaked document may be relevant evidence, but its existence alone does not prove misconduct or establish a legal finding. UCLA Journal of International Law and Foreign Affairs, 2021

Was the intrusion ever independently verified?
The public technical narrative remains substantially Fisher’s own. VICE explicitly said it could not verify every step, and the reporting cited no complete public forensic account from Hacking Team or Italian authorities. That means the reported chain—from the zero-day to administrator access, credential capture, and source-code access—should be described as Fisher’s claim, not as a confirmed sequence.
A 2020 scholarly analysis by Peter Maynard and Kieran McLaughlin examines Phineas Fisher’s claimed intrusions using self-published materials, reporting, and official documentation. The authors distinguish techniques explicitly described in sources from techniques inferred in their mapping. Their framework helps explain how researchers qualify claims; it is not independent confirmation of every operational detail Fisher gave about Hacking Team.

Rank #4
Why the distinction matters
The case illustrates two separate issues: a surveillance vendor’s sensitive data can expose customers and internal operations when breached, and materials obtained unlawfully may raise difficult questions about authenticity, context, and admissibility. Neither the attacker’s political rationale nor the contents of a leak settle whether conduct was lawful. Fisher himself acknowledged that distinction in his email to VICE; legal conclusions require more than an attacker’s account or a leaked file.
