The Everest ransomware group is claiming a significant breach involving McDonald’s India, alleging that hundreds of gigabytes of data were taken from the company’s environment.

Attackers Allege Large-Scale Data Exfiltration

The attackers say the intrusion resulted in the extraction of roughly 861 GB of information and that proof of access has already been shared within their underground channels.

The group alleges that the stolen dataset contains a mix of confidential business records and customer-related information. If the claims are accurate, the exposed material could be leveraged for large-scale phishing activity, identity misuse, or further downstream attacks targeting customers and partners.

Everest ransomware group has built a reputation around data-focused extortion, prioritizing theft and public pressure over pure system encryption.

Active since 2020, the group has previously been linked to high-impact breaches across multiple sectors, often involving unusually large data volumes.

At this time, McDonald’s India has not publicly acknowledged the incident. Should the claims be validated, the alleged breach would represent another serious test of cybersecurity resilience for large consumer-facing enterprises operating in the region.
