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 Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating unauthorized actor accessed CESA’s network and Exploit Public-Facing Application (T1190) with lower confidence (40%), supported by evidence indicating breach occurred when an unauthorized actor accessed CESA’s network. Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate confidence (50%), supported by evidence indicating unauthorized actor accessed CESA’s network (implied credential misuse) and OS Credential Dumping (T1003) with lower confidence (40%), supported by evidence indicating pII including Social Security numbers compromised.
