CanisterWorm is a self-propagating malware that has been used by TeamPCP in credential harvesting and software supply chain campaigns since at least 2026. CanisterWorm has used npm credentials to infect software packages and propagate across developer ecosystems. CanisterWorm has a targeted wiper component and can use decentralized C2 infrastructure implemented via an Internet Computer Protocol (ICP) blockchain canister.[1][2][3][4]

Standing S9042
Reach is how much of ATT&CK this tool touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.

Threat group161% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
