The Everest ransomware group is a well-established ransomware-as-a-service (RaaS) operation that has been active since 2020. The group targets medium to large organizations across a wide range of sectors, including healthcare, manufacturing, financial services, and government-related entities. Everest is known for its deliberate, targeted approach rather than indiscriminate mass attacks.

Everest relies heavily on double extortion tactics, stealing sensitive data before encrypting systems and threatening to publish the information on its leak site if ransom demands are not met. Initial access is commonly achieved through compromised credentials, phishing, and exploitation of exposed or unpatched services, followed by lateral movement using legitimate administrative tools to blend in with normal network activity.

From a technical standpoint, Everest uses strong encryption, attempts to disable backups and security controls, and often spends time conducting reconnaissance before deploying ransomware. The group’s longevity and consistent activity highlight the continued effectiveness of targeted ransomware campaigns, particularly against organizations with weak credential hygiene, limited network segmentation, or insufficient monitoring of data exfiltration.
