Know Your Adversary describes APT37 activity tracked as Squid Werewolf using the RESTLEAF implant with abuse of Zoho WorkDrive, a legitimate cloud file-management and collaboration platform. The excerpt focuses on proactive hunting for communications to workdrive.zohoexternal.com, especially DNS telemetry recorded as dnsreqwin events. The tradecraft matters because use of a trusted SaaS platform can blend into normal enterprise network activity and may require defenders to separate expected Zoho WorkDrive usage from suspicious APT37-linked communications.
