How to request a review

File review

Arctic Wolf acquired Cylance endpoint-security assets. VirusTotal now lists an Arctic Wolf contact for file-engine issues.

  1. Email the Arctic Wolf address listed by VirusTotal and identify Cylance as the historical engine name.
  2. Include the file SHA-256, VirusTotal report URL, detection details and the file's legitimate purpose.
  3. Ask whether the current endpoint team can review the legacy detection.
  • This record preserves the historical Cylance name; it does not assert that Cylance remains a separately active VirusTotal engine.
  • The listed mailbox has not been delivery-tested.

Scope & contact notes

  • Listed in VirusTotal search-prefix documentation but absent from the contributor roster snapshot; this is not proof the engine is currently active.
  • This name appears in a VirusTotal engine-prefix list or contact table but is not matched to a current contributor entry. Current engine activity is unconfirmed.
