> thegentlemen ransomware operators claim to have compromised Mercado Libre and exfiltrated data from over 118k users.

Ransomware.live reports that the thegentlemen ransomware group has claimed responsibility for a compromise of Mercado Libre, the major Latin American e-commerce platform. According to the posting indexed by the platform, the attackers claim to have accessed credentials for 118,244 users and 4 third-party employee accounts, along with identifying 100 items of external attack surface and DNS records associated with the victim's infrastructure. The report notes this is publicly visible information indexed from ransomware operator postings and does not include access to underlying stolen data itself.

Mercado Libre operates across multiple countries in Latin America and serves as a critical commerce platform. The scale of user credential exposure (over 118k accounts) represents a significant data breach affecting legitimate users of the platform. Defenders at Mercado Libre and related organizations should treat this as an active compromise requiring incident response investigation, credential rotation, and notification of affected users in accordance with applicable data protection regulations.
