What to do
If you are a customer, employee, partner, or supplier of Lider Aviacao, watch Lider Aviacao's official channels and the Thegentlemen leak site listing for any update confirming what, if anything, was actually taken, and treat unsolicited messages claiming to be from Lider Aviacao with caution until the company confirms details. There is no version or product to check since this is a claim against a company, not a software flaw.
Reported details
The claim comes from a ransomware.live listing showing the leak site of the group Thegentlemen added Lider Aviacao as a victim on 2026-09-05 at 18:29 UTC. No technical detail about how the network was accessed, what systems were affected, or how much data was taken has been published by the group or the company. This is a leak-site claim, not an independently verified breach.
