Breach #079

The company that hacked governments got hacked itself. 400GB of everything.

On 5 July 2015, the Twitter account of Hacking Team — an Italian company that sold intrusion and surveillance technology to government agencies worldwide — was taken over and used to announce that the company had been comprehensively breached. A 400GB torrent of internal data was published, containing the source code for Hacking Team's Remote Control System (RCS) surveillance platform, at least three zero-day exploits (for Adobe Flash and Windows), complete client lists, internal emails, invoices, and financial records.

The leaked client lists revealed that Hacking Team had sold surveillance tools to governments including Sudan, Ethiopia, Saudi Arabia, and other regimes with documented records of human rights abuses — despite the company's claims that it did not sell to oppressive governments. The leaked zero-day exploits were immediately weaponised by cybercriminals worldwide, with exploit kits incorporating the Flash vulnerabilities within days. The breach demonstrated the catastrophic consequences of a surveillance vendor compromise — and the irony of a company that sells hacking tools being unable to protect its own systems.

Zero-days in the wild, clients exposed, trust destroyed.

Zero-Days Immediately Weaponised
The leaked Flash and Windows exploits were incorporated into criminal exploit kits within days — dramatically expanding the threat landscape. Organisations that had not patched Flash were immediately at risk from attacks using Hacking Team's previously secret exploits. <a href="/cyber-essentials">Cyber Essentials Danzell</a> mandates 14-day patching — the control that protected organisations when these zero-days went from secret to public overnight.
Surveillance Tool Source Code Published
The source code for RCS — Hacking Team's flagship surveillance platform — was published in full. This allowed security researchers to understand how government surveillance tools operate, but also allowed attackers to study and adapt the techniques for their own use. The parallel with <a href="/blog/anatomy-of-a-breach-adobe">Adobe's source code theft</a> is direct: stolen source code enables the discovery of new vulnerabilities.
Client Lists Exposed Authoritarian Sales
The leaked invoices and client communications proved that Hacking Team sold surveillance tools to regimes that used them to monitor journalists, dissidents, and human rights activists — the same concern that motivated the <a href="/blog/anatomy-of-a-breach-diginotar-ca">DigiNotar</a> and <a href="/blog/anatomy-of-a-breach-comodo-ca">Comodo</a> CA compromises.
The Cobbler's Children
Hacking Team — a company that sold offensive cybersecurity tools — could not defend its own network. Like <a href="/blog/anatomy-of-a-breach-hbgary-federal">HBGary Federal</a> in 2011, the breach proved that expertise in offensive security does not confer defensive immunity. Our <a href="/penetration-testing">penetration testing</a> verifies that your defences work — regardless of your organisation's security expertise.
Lessons

When surveillance vendors are breached, everyone is at risk.

The Hacking Team breach had consequences far beyond the company itself. The leaked zero-days endangered every organisation that ran Flash or Windows. The leaked source code armed attackers with government-grade surveillance techniques. And the exposure of client relationships damaged trust in the entire commercial surveillance industry.

For UK organisations, the lesson is about supply chain and patching: when zero-day exploits leak — whether from Hacking Team, Operation Aurora's Elderwood Group, or future leak events — the only defence is rapid patching. Cyber Essentials Danzell's 14-day patching window exists precisely for this scenario. Our vulnerability scanning identifies systems running exploitable software. SOC in a Box monitors for exploitation attempts using leaked exploits. And UK Cyber Defence's threat intelligence provides early warning when new exploits enter the wild.

Patch Before the Exploits Spread

When zero-days leak, the clock starts. Can you patch in 14 days?

Breach #013 in our Anatomy of a Breach series. In January 2010, Google disclosed that it had been the victim of a sophisticated cyberattack originating from China. Operation Aurora — named after a file path in the malware — targeted 34 companies including Adobe, Yahoo, Symantec, and Northrop Grumman, using an Internet Explorer zero-day to steal intellectual property and access the Gmail accounts of Chinese human rights activists. The attack that proved nation-state cyber espionage was no longer just a military concern.

Anatomy of a Breach: Microsoft SharePoint — Zero-Day Exploited by Three Chinese Groups, 400+ Organisations Compromised Including NNSA

Breach #199. In July 2025, it was revealed that a zero-day vulnerability in Microsoft SharePoint had been exploited by three Chinese state-linked hacking groups to compromise over 400 organisations worldwide — including the US National Nuclear Security Administration (NNSA), the federal agency responsible for maintaining the US nuclear weapons stockpile. The vulnerability enabled remote code execution against self-hosted SharePoint servers. Thousands of vulnerable servers remained online even after the vulnerability was disclosed. The breach demonstrated the extraordinary risk of centralising sensitive data in a single collaboration platform — especially when that platform is targeted by nation-state adversaries.

Breach #184. In March 2024, AT&T confirmed that a dataset containing the personal information of approximately 73 million current and former customers had been published on the dark web. The data — including names, addresses, phone numbers, dates of birth, Social Security numbers, and encrypted AT&T account passcodes (which security researchers quickly cracked) — appeared to originate from a breach dating to approximately 2019. AT&T had previously denied the data was from its systems. The breach demonstrated that stolen data surfaces years later, and that denial does not make a breach disappear.
