MITRE ATT&CK® Correlation Analysis

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 significant IT failure leading to a data breach and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating iT failure leading to data breach (possible insider/credential misuse). Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate confidence (50%), supported by evidence indicating iT failure leading to exposure of transaction histories and NINs and OS Credential Dumping (T1003) with lower confidence (40%), supported by evidence indicating high sensitivity of compromised data (national insurance numbers). Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating transaction histories and national insurance numbers compromised and Data from Information Repositories (T1213) with moderate to high confidence (70%), supported by evidence indicating 447,936 customer records exposed across Lloyds brands.
