Warlock is a China-linked ransomware group
Assessment
The China nexus is a vendor assessment, not an established fact. Microsoft assesses Storm-2603 with moderate confidence to be China-based and says it has not linked it to other known Chinese actors; Symantec calls it China-nexus; Sophos's Counter Threat Unit says it has insufficient evidence to corroborate the attribution. Media headlines such as TechJuice's state the China link flatly as 'A China-linked ransomware group called Warlock,' collapsing a moderate-confidence, partly-disputed assessment into a settled fact.

A named source states this as its own assessment, at its own stated confidence, rather than as established fact. Attribution to a nation state usually sits here. The assessment is real and reportable; treating it as settled is the error.
