A threat actor claims to have breached Ryanair, and flight compensation data is now circulating on underground cybercrime forums.
Many passengers seek compensation for flight delays, which is guaranteed by EU regulations.
While receiving a decent sum for the inconvenience is pleasing, submitting your data to airlines’ systems might pose additional risks. Especially, as compensation claims often require submitting an extensive amount of personal data.
That might be the case with current hacker claims on a well-known underground forum. Attackers allege that they have targeted Ryanair, an Irish ultra-low-cost airline and Europe's largest carrier by passenger numbers.
While the airline has not confirmed the incident at the time of writing, the exposed data suggests potential access to sensitive internal systems.
The claims were first flagged by cybersecurity monitoring publication Daily Dark Web. The alleged attacker shared a data sample along with their listing.
Judging from the provided screenshots, the data may be from the company’s internal legal email system and its flight compensation and ticketing systems.
Court documents allegedly leaked
One portion of the leak resembles structured records from an internal legal correspondence or case management platform.
The exposed data includes:
- Email subjects, bodies, and timestamps
- Sender and recipient details (including CC and BCC)
- Attached court documents and associated storage links
- Case references tied to legal proceedings
- Court deadlines and procedural notes
In one example, an email references defense deadlines and an “OPS spreadsheet,” hinting at internal workflows used to track legal operations.
Mentions of specific cases and court timelines suggest this system may be used to coordinate active litigation.
Flight information for sale
Another data sample is way more sensitive. It’s a dump from what appears to be a legal claims management platform handling air passenger compensation cases for flight delays and cancellations under EU Regulation 261/2004.
Sample entries reference flights across major European routes, including Paris Beauvais, Bologna, Barcelona, and Cagliari.
If authentic, the exposed records include:
- Full names, customer IDs
- Lawyer names and email addresses
- IBANs, SWIFT codes, bank names, payment identifiers
- Flight numbers, routes, airports, and travel dates
- Legal references, decision numbers, procedural details
- References to "Inhouse Team Ryanair (ITA)", organization IDs, and descriptions
Cybernews has reached out to Ryanair for comment, but a response has not yet been received.
Record-breaking months of aviation breaches
The aviation sector has been increasingly targeted by cybercriminals. Through 2025 and the first half of 2026, multiple airlines and aviation suppliers were hit by cyberattacks, exposing millions of passenger records and disrupting airport operations.
In June 2025, Canada's WestJet confirmed a breach that would eventually see 1.2 million American customers notified that their data had been stolen. That same month, Hawaiian Airlines was knocked offline in a suspected ransomware strike that took down internal network systems.
In September of the same year, the J Group ransomware crew claimed German aviation firm FAI, leaking nearly 3TB of sensitive data that included employee records and medical files.
Weeks later, the Everest ransomware group took credit for breaching Collins Aerospace and its MUSE check-in platform. The attack rippled across European airports, disrupting services.
October brought American Airlines into the crosshairs via the Clop-Oracle attack spree, and by November, Spain's flagship carrier Iberia was confirming a breach of its own, with threat actors claiming access to 77GB of stolen data.
By the beginning of 2026, the attacks had not slowed down. The Qilin ransomware gang came out swinging in January, claiming a breach of Tulsa International Airport and leaking internal data.
In February, Qilin was back, this time targeting Malaysia Airlines in yet another claimed compromise.
