About the Ailock group

AiLock is a ransomware operation that emerged in early 2025, marketing itself as AI-assisted ransomware using a hybrid ChaCha20/NTRUEncrypt encryption scheme and double-extortion tactics, actively recruiting affiliates and threatening regulatory reporting if ransoms are unpaid. Ailock has listed 47 victims since April 2015.

Incident Analysis

Ferrovial was targeted by Ailock ransomware, one of the most active ransomware groups in our database with 51 confirmed victims globally. The attack was disclosed on July 15, 2026, when Ferrovial appeared on the group's dark web leak site.

Ferrovial is based in Spain , operating in the Construction sector. Spain ranks #9 globally for ransomware attacks, with 425 victims in our database.

Sector context: Construction firms often hold sensitive project data, client financials, and intellectual property. The industry's typically lean IT security teams can make them more vulnerable.

Ailock typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
