Everest is a ransomware and data-extortion group that emerged in late 2024 and operates as a ransomware-as-a-service (RaaS) brand, reportedly recruiting affiliates on underground forums including RAMP, per Cyberint/Check Point research (2025). It uses double extortion - stealing data and encrypting systems - and is notable for publicly marketing a 'no-leak' pledge, claiming it deletes stolen data and provides proof of deletion after payment rather than reselling or publishing it (vendor reporting, 2025). The group runs a Tor leak site where it names victims; attribution and national origin remain unknown, and no law-enforcement action against it has been publicly announced. Dashboard tracking shows low-volume, intermittent leak-site activity: 4 posts total since 2026-09-04, most recently 2026-09-07. Everest was cited in 2025-26 regional threat coverage discussing Qatar's threat landscape, and it should not be confused with a distinct older Everest-named file-encrypting strain documented around 2020.
Tactics & tooling
- Double extortion: exfiltrates victim data and deploys encryption, threatening publication on its Tor leak site
- RaaS model: advertises for affiliates on underground forums, including RAMP, per Cyberint/Check Point research (2025); affiliate infrastructure attribution largely unknown
- 'No-leak' payment pledge: publicly claims stolen data will be deleted, with proof of deletion provided after ransom payment, rather than leaked or resold (per Cyberint/Check Point, 2025)
- Victim shaming via leak-site posts naming targeted organizations; observed posting cadence is low-volume and intermittent (dashboard tracking, 2026)
- Initial-access tradecraft not comprehensively documented in public reporting; no specific CVE exploitation or access-broker purchases publicly confirmed - unknown as of the dashboard period
