Collins Aerospace attack claimed by Everest, linking ransomware group to last month's European airport chaos

The Everest ransomware group is claiming responsibility for the September breach of Collins Aerospace and its MUSE check-in software – in an attack that impacted multiple major airports across Europe, causing travel chaos for days.
The Everest ransomware cartel, which also made waves last month with a purported attack on luxury automaker BMW, claims to have exfiltrated a 50+ GB database from one of the world’s leading commercial and military defense companies.
A spokesperson from RTX, Collins Aerospace’s parent company, put out a statement identifying a “cyber-related disruption” in its Arinc cMUSE software at certain airports… and that the impact was “limited to electronic customer check-in and baggage drop and could be mitigated with manual check-in operations.”
Collins Aerospace was reported to have told Heathrow that an estimated 1,000 computers had been “corrupted” in the attack, and could only be brought back online in person.
