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 Supply Chain Compromise: Compromise Software Dependencies and Development Tools (T1195.001) with high confidence (95%), with evidence including malicious npm packages impersonating legitimate libraries, and typosquatting and dependency confusion attack vectors. Under the Execution tactic, the analysis identified Command and Scripting Interpreter: JavaScript (T1059.007) with high confidence (90%), supported by evidence indicating malicious code in npm packages targeting Node.js 18+ environments. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Private Keys (T1552.004) with high confidence (95%), with evidence including packages designed to intercept private key operations, and wallet private keys stolen via hijacked Base58 decode() calls. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating private keys stolen from local systems via malicious npm packages. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (95%), with evidence including stolen keys sent to hardcoded Telegram bot (@Test20131_Bot), and data exfiltration to Telegram C2 server. Under the Command and Control tactic, the analysis identified Web Service: Bidirectional Communication (T1102.002) with high confidence (90%), with evidence including telegram-based command-and-control (C2) server, and attack infrastructure relies solely on Telegram bot. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (85%), with evidence including obfuscation techniques including array-rotation ciphers, and malicious code concealed in npm packages and Masquerading: Match Legitimate Name or Location (T1036.005) with high confidence (90%), supported by evidence indicating packages impersonate legitimate crypto libraries (e.g., raydium-bs58, ethersproject-wallet). Under the Impact tactic, the analysis identified Resource Hijacking (T1496) with moderate to high confidence (80%), supported by evidence indicating attackers drain compromised cryptocurrency wallets. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
