Incident Score: Analysis & Impact (VIKHARDWI1781800805)

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 fulcrumSec accessed the data through compromised credentials tied to GSG’s shared AWS infrastructure. Under the Credential Access tactic, the analysis identified Cloud Instance Metadata API (T1552.005) with moderate to high confidence (70%), supported by evidence indicating 168 AWS secrets compromised in the breach and Password Cracking (T1110.002) with moderate to high confidence (80%), supported by evidence indicating 11,176 staff password hashes (SHA-256) exposed. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (80%), supported by evidence indicating 183,164 user accounts (students, parents, staff) compromised and File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating 112 source code repositories and 9.4 million internal messages accessed. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating 35,938 student enrollment records, 9.4M messages, 8.6M attendance records compromised and Data from Information Repositories (T1213) with moderate to high confidence (80%), supported by evidence indicating 122,862 Twilio SMS messages and 46,901 job applicant folders exfiltrated. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating fulcrumSec leaked the data and provided findings to DataBreaches and Transfer Data to Cloud Account (T1537) with moderate to high confidence (70%), supported by evidence indicating aI-assisted crawling used to extract records from AWS database. Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (30%), supported by evidence indicating no evidence of data destruction, but high-volume exfiltration occurred and Data Manipulation: Transmitted Data Manipulation (T1565.002) with lower confidence (40%), supported by evidence indicating minor errors in deduplication noted during AI-assisted crawling. Under the Defense Evasion tactic, the analysis identified Use Alternate Authentication Material: Application Access Token (T1550.004) with moderate to high confidence (70%), supported by evidence indicating compromised credentials tied to shared AWS infrastructure. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
