Iberia Airlines Notifies Customers of Supply Chain Data Breach

Iberia Airlines Notifies Customers of Supply Chain Data Breach

Customers of Iberia Airlines will need to be on high alert for phishing attacks after the carrier revealed personal information had been compromised via a supplier.

Owned by the International Airlines Group (IAG) that also contains British Airways and Aer Lingus, Spain’s largest airline began sending notifications out over the weekend.

Cyber tracker Hackmanac shared the note, written in Spanish, in a post on X (formerly Twitter) yesterday.

“Unfortunately, Iberia Airlines of Spain has detected a security incident related to unauthorized access to the systems of an Iberia supplier, which has compromised the confidentiality of certain data,” it explained (translation).

“Despite the security measures implemented by Iberia, we have evidence of unauthorized access to certain personal data of our customers, which could include some of yours. The current investigation indicates that data such as your first and last name; email address; or loyalty card identification number (Iberia Club) may have been compromised.”

The airline was at pains to point out that no logins or customer financial details had been taken in the raid. It claimed to have taken “all the necessary technical and organizational measures” to contain and recover from the incident, including new checks to prevent unauthorized changes to accounts.

Any customers wanting to change their password must now input a verification code that will be sent by the airline.

The firm is also continuing to monitor for suspicious activity and has notified the relevant authorities, it said.

Question Marks Remain

Iberia Airlines said it had no evidence the stolen information is being used fraudulently, but urged customers to look out for suspicious communications. The compromised information could be used to make follow-on phishing attacks appear legitimate.

It’s unclear what type of supplier was compromised in the attack. However, Hackmanac revealed on November 14 that a threat actor was trying to sell a 77GB trove of passenger data for $150,000.

That collection apparently included technical material on A320 and A321 aircraft, AMP maintenance files, engine data, and internal documents with signatures and certificates.

Several airlines including Air Franceand Qantaswere also linked to a sophisticated Scattered Lapsus$ Hunters campaign targeting Salesforce customers.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
