Iberia issued its data security incident notice about a week after a threat actor claimed on a hacking forum to have stolen roughly 77 gigabytes of data from the airline’s systems. The attacker said the trove was “extracted directly from the airline’s internal servers” and included A320/A321 technical documents, AMP maintenance files, engine data, and other internal records.
The threat actor also stated that they are willing to sell the entire stolen database for $150,000.
