Incident Score: Analysis & Impact (GOOAMANPMGIT1773319158)

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 Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating 83% of cloud intrusions in H2 2025 stemmed from identity compromise, Supply Chain Compromise: Compromise Software Dependencies and Development Tools (T1195.002) with moderate to high confidence (80%), supported by evidence indicating malicious NPM package (QUIETVAULT credential stealer), and Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating software-based initial access vectors surged from 2.9% to 44.5%. Under the Execution tactic, the analysis identified User Execution: Malicious Link (T1204.001) with moderate confidence (60%), supported by evidence indicating phishing have dominated breach vectors and Serverless Execution (T1648) with moderate to high confidence (70%), supported by evidence indicating exploited unconstrained CI/CD service accounts in Kubernetes. Under the Persistence tactic, the analysis identified Account Manipulation (T1098) with moderate to high confidence (80%), supported by evidence indicating uNC6426 leveraged a compromised GitHub token to escalate to full AWS admin access and Create Account: Cloud Account (T1136.003) with moderate confidence (50%), supported by evidence indicating overprovision access prioritizing operational convenience over security. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating uNC6426 escalated to full AWS admin access within 72 hours and Abuse Elevation Control Mechanism: Bypass User Account Control (T1548.002) with moderate confidence (60%), supported by evidence indicating bypassing human oversight entirely via CI/CD service accounts. Under the Defense Evasion tactic, the analysis identified Use Alternate Authentication Material: Application Access Token (T1550.001) with moderate to high confidence (80%), supported by evidence indicating compromised GitHub token used for AWS admin access, Valid Accounts: Cloud Accounts (T1078.004) with high confidence (90%), supported by evidence indicating 83% of cloud intrusions stemmed from identity compromise, and Hide Artifacts: Email Hiding Rules (T1564.008) with moderate confidence (50%), supported by evidence indicating lLM process execution invisible to traditional endpoint detection. Under the Credential Access tactic, the analysis identified Steal Application Access Token (T1528) with high confidence (90%), supported by evidence indicating qUIETVAULT credential stealer embedded in malicious NPM package, Unsecured Credentials: Credentials In Files (T1552.001) with moderate to high confidence (80%), supported by evidence indicating scanned for sensitive files (.env, .conf, .log) before extracting credentials, and Brute Force: Password Guessing (T1110.001) with moderate confidence (60%), supported by evidence indicating stolen credentials and phishing have dominated breach vectors. Under the Discovery tactic, the analysis identified Account Discovery: Cloud Account (T1087.004) with moderate to high confidence (80%), supported by evidence indicating aI agents traverse environments at machine speed, File and Directory Discovery (T1083) with high confidence (90%), supported by evidence indicating hijacked local LLM to scan for sensitive files (.env, .conf, .log), and Network Service Discovery (T1046) with moderate to high confidence (70%), supported by evidence indicating automated reconnaissance engine in LLM environments. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating extracted credentials from sensitive files (.env, .conf, .log) and Data from Information Repositories: Code Repositories (T1213.003) with moderate to high confidence (80%), supported by evidence indicating compromised GitHub token used for AWS admin access. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate to high confidence (70%), supported by evidence indicating exfiltration over C2 channel likely via standard web protocols. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating data exfiltration confirmed in QUIETVAULT attack and Transfer Data to Cloud Account (T1537) with moderate to high confidence (70%), supported by evidence indicating credentials and sensitive files exfiltrated via cloud services. Under the Impact tactic, the analysis identified Resource Hijacking (T1496) with moderate to high confidence (80%), supported by evidence indicating threat actors deployed cryptocurrency miners within 48 hours of CVE disclosure and Account Access Removal (T1531) with moderate confidence (60%), supported by evidence indicating bypassed human oversight; automated exploitation. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
