Incident Score: Analysis & Impact (YOUGOO1782210666)

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 Exploit Public-Facing Application (T1190) with high confidence (90%), supported by evidence indicating exposed internal API (`cloudcrmipfrontend-pa.googleapis.com`) and External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating debugging endpoints exposed via internal API. Under the Discovery tactic, the analysis identified Account Discovery: Cloud Account (T1087.004) with moderate to high confidence (80%), supported by evidence indicating leaked protobuf descriptors for internal services (YouTube, Google CRM) and Network Service Discovery (T1046) with high confidence (90%), supported by evidence indicating automated fuzzing tool flagged internal API exposing endpoints. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Cloud Instance Metadata API (T1552.006) with moderate to high confidence (70%), supported by evidence indicating leaked default `clientId` enabling malicious workflow creation. Under the Privilege Escalation tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with high confidence (90%), supported by evidence indicating manipulated internal ACL endpoint to add attacker-controlled accounts and Abuse Elevation Control Mechanism: Bypass User Account Control (T1548.002) with moderate to high confidence (80%), supported by evidence indicating bypassed two-person approval for workflow publishing. Under the Execution tactic, the analysis identified Container Administration Command (T1609) with high confidence (90%), supported by evidence indicating executed arbitrary RPC calls with privileged service identity and Exploitation for Client Execution (T1203) with moderate to high confidence (80%), supported by evidence indicating exploited GenericStubbyTypedTaskV2 to trigger arbitrary RPC calls. Under the Lateral Movement tactic, the analysis identified Use Alternate Authentication Material: Application Access Token (T1550.001) with moderate to high confidence (80%), supported by evidence indicating cross-tenant access to workflow definitions via IDOR. Under the Defense Evasion tactic, the analysis identified Subvert Trust Controls: SIP and Trust Provider Hijacking (T1553.003) with moderate to high confidence (70%), supported by evidence indicating partial patch deployment allowed RCE chain persistence and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating manipulated internal ACL endpoint to bypass approvals. Under the Collection tactic, the analysis identified Data from Cloud Storage Object (T1213.003) with high confidence (90%), supported by evidence indicating leaked protobuf descriptors for YouTube and Google CRM. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
