ComponentValueReasoning
Sentence-Years1018 USC 1029(a)(2)
× Contribution1.5Built the exploit: Anthropic says the actor used Claude Code to build the service's card-validation framework, failover and batch processing for stolen cards; Claude wrote the fraud tooling the service ran on.
× Blast Radius1Third party: The victims are the cardholders and card issuers, private parties, so blast radius is third party.
× Legal status1Crime.
+ Tradecraft2Anthropic says Claude built "intelligent request throttling to avoid detection", which is covering its tracks.
+ Guardrails0Guardrails intact: The report describes no jailbreak or safety bypass; the model was used as shipped.
+ Dwell Time0Anthropic gives no dates, so date_precision is before with the report's publication date; dwell is counted from that latest possible date (0 days) and never inflated. Anthropic found the activity itself.
