Disclosure context

About Everest

Everest is a financially-motivated ransomware group that emerged in September 2021, operating with a focus on profit-driven extortion campaigns against organizations primarily in the United States and Europe. The group's country of origin and specific affiliations remain undocumented in public threat intelligence reporting, though their operational patterns suggest they likely operate as an independent entity rather than a formal ransomware-as-a-service model. Limited public documentation exists regarding Everest's specific attack methodologies, initial access vectors, or technical capabilities, though their victim profile indicates they employ standard ransomware tactics targeting a diverse range of sectors including healthcare, technology, business services, and manufacturing organizations. Since their emergence, Everest has claimed responsibility for attacks against 339 victims across multiple countries, with the United States, United Kingdom, Italy, Germany, and Spain representing their primary geographic targets, though no specific high-profile incidents or major ransoms have been publicly documented by law enforcement or major security firms. As of current reporting, Everest appears to remain an active threat actor, though the limited public intelligence available suggests they operate as a lower-tier ransomware group compared to more prominent and well-documented criminal organizations. The group has been linked to 360 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post May 7, 2026. The operation is currently active.

Attack summary

Severity: medium — Status is listed as data_published, implying exfiltration has occurred, but the truncated leak post contains no specifics about data type, volume, or proof files, preventing a higher severity classification. Polycom's enterprise and government client base raises potential sensitivity.

The Everest ransomware group claims to have attacked Polycom and lists the disclosure status as data_published, suggesting exfiltration and publication of data; however, the leak post itself contains no substantive detail about the nature or volume of the data stolen.
