ComponentValueReasoning
Sentence-Years518 USC 1030(a)(2)(C)
× Contribution0.5Wrote the content: Google says the clusters "used AI coding assistants such as DeepSeek-Coder to develop Python-based Remote Access Trojans (RATs)" for the foothold stage of their attacks; humans deployed them, so this is written content (malware components).
× Blast Radius1Third party: Google says the lures and malware were used "to target cryptocurrency organizations" to "support cryptocurrency theft"; the victims are private companies, so blast radius is third party.
× Legal status1Crime.
+ Tradecraft5Google says the DeepSeek-Coder-built RATs incorporated "cross-platform persistence" and "defense evasion". Lateral-movement scripts are attributed only to unnamed "LLMs", so they aren't credited here.
+ Guardrails0Guardrails intact: DeepSeek-Coder is an open-weight model; Google doesn't say it was jailbroken or modified, so guardrails are scored intact.
+ Dwell Time3The report gives no dates for the activity, so date_precision is before with the report's publication date (2026-09-08); dwell is counted from that latest possible date (0 days) and never inflated. Google, not DeepSeek, detected and reported it.
