Incident Score: Analysis & Impact (DEEKIM1790217824)

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Trusted Relationship (T1199) with moderate to high confidence (80%), supported by evidence indicating rerouted queries to its servers, effectively providing users with Claude’s responses. Under the Collection tactic, the analysis identified Data from Information Repositories (T1213) with high confidence (90%), supported by evidence indicating illicit distillation training smaller AI models using outputs from Anthropic’s Claude and Data from Local System (T1005) with moderate to high confidence (70%), supported by evidence indicating sensitive user data, potentially including police, military, or state-linked corporate data. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating secretly routed sensitive user data to Anthropic’s servers and Transfer Data to Cloud Account (T1537) with moderate to high confidence (80%), supported by evidence indicating data was transferred to U.S.-based servers. Under the Credential Access tactic, the analysis identified Steal Application Access Token (T1528) with moderate confidence (60%), supported by evidence indicating unauthorized API routing / Data exfiltration. Under the Defense Evasion tactic, the analysis identified Masquerading (T1036) with moderate to high confidence (70%), supported by evidence indicating illicit distillation training smaller AI models using outputs from Claude and Hide Artifacts: Email Hiding Rules (T1564.008) with moderate confidence (50%), supported by evidence indicating no penalties have been announced, underscores scrutiny of AI development. Under the Impact tactic, the analysis identified Defacement (T1491) with lower confidence (40%), supported by evidence indicating brand reputation impact such as High (for DeepSeek and Moonshot AI) and Service Stop (T1489) with lower confidence (30%), supported by evidence indicating potential IPO delays for Moonshot AI. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
