Incident Score: Analysis & Impact (ALC1773239671)

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 moderate confidence (50%), supported by evidence indicating disabled its systems after detecting suspicious activity and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating lockBit known for using compromised credentials in attacks. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating lockBit ransomware encrypts systems and exfiltrates data. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating lockBit likely maintains access via compromised accounts. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating compromised credentials may grant elevated access. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (70%), supported by evidence indicating lockBit ransomware known for obfuscation techniques and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating district disabled systems after detecting suspicious activity. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (60%), supported by evidence indicating lockBit known for credential harvesting in attacks. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate confidence (60%), supported by evidence indicating lockBit likely enumerates accounts for lateral movement and File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating ransomware identifies files for encryption and exfiltration. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate confidence (60%), supported by evidence indicating lockBit commonly uses RDP for lateral movement. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating lockBit exfiltrates data before encryption. 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 lockBit uses C2 channels for data exfiltration. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating lockBit exfiltrates data before encryption. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating lockBit ransomware encrypts systems and Defacement: Internal Defacement (T1491.001) with moderate to high confidence (70%), supported by evidence indicating ransomware typically leaves ransom notes on systems. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
