Everest Ransomware Leaks Collins Aerospace Airport Data

Last Updated: November 14, 2025By

Continuing Data Breach Exposes Collins Aerospace Files

In a dramatic twist, a Russian ransomware group recently made waves by leaking sensitive data they claim to have stolen from Collins Aerospace. Known for supporting major airports across Europe, this breach adds to the turmoil seen in recent months. From disrupted check-ins to potential data exposure, it’s been a rocky road for European airports.

The hackers shared a dataset they said belonged to Collins Aerospace, a critical player in technology systems that streamline check-ins and boarding procedures at airports. According to reports, the breach traces back to September 19, when Collins detected a “technical issue” linked to a cyber disruption in its software used for managing check-ins and baggage. While Collins’s parent company, RTX, noted most issues were handled manually, the European Union’s cybersecurity agency confirmed that ransomware impacted automated systems.

In a further twist, hackers threatened to release passenger data from the Dublin Airport incident tied to the same breach. Though a link to this information was posted on November 11, it was soon removed. The ongoing situation paints a stark picture of the vulnerabilities in aviation cybersecurity.

What’s Behind the Collins Aerospace Leak?

The known leak of 23GB from Collins Aerospace hints at a treasure trove for cybercriminals. The data set includes binaries and documentation from the company’s operations. Cybersecurity experts fear these files could aid attackers in unveiling future system vulnerabilities.

One file allegedly contains around 1.5 million passenger records, detailing names, travel dates, and flight paths. Despite its size, this segment appears to be just a fraction of the total breached data. Cybernews sought a response from Collins Aerospace but awaits their comments.

The aviation sector thus faces new challenges, necessitating urgent improvements in data protection and cybersecurity protocols.

A Closer Look at the Everest Group

The Everest group, active since July 2021, has recently targeted aviation heavily. Just days ago, they attacked the Italian company SIAD Group, though it reported no major disruptions. Earlier claims by Everest include attacking companies like BMW and DZ Bank’s subsidiary, though the latter refuted these allegations.

In July, Everest also announced a breach of Mailchimp but with seemingly little impact. Their reputation for low-profile yet impactful attacks highlights the critical need for fortified cybersecurity across sectors. The group’s activities serve as a sober reminder to stay ahead of potential cyber threats.

As cybercrime evolves, vigilance and security remain top priorities for digital safety. Keep abreast of cyber news and protect sensitive information from falling into the wrong hands.
