XWorm Plugins Explained
A defensive architectural explanation of why XWorm's modularity means two samples labeled 'XWorm' may have very different capability profiles.

XWorm is not simply one fixed executable with an identical capability set. Plugins can extend the RAT. This means the combination of core plus plugins creates a different behavioral profile per operator.

Capability labels used on this site
- Core capability — present in the base client.
- Plugin capability — loaded by a modular component.
- Campaign-specific capability — observed in a particular campaign.
- Modified-build capability — added by a cracker or third party.
Therefore "XWorm capability" should not automatically mean "capability observed in every XWorm sample." See Capability Matrix and Architecture.
