The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

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 Trusted Relationship (T1199) with high confidence (95%), with evidence including vendor, Financial Business and Consumer Solutions (FBCS), exposed the personal data, and data Breach (Third-Party Vendor). Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with moderate to high confidence (85%), with evidence including data exfiltration such as Yes, and exposed the personal data of ~237,000 customers and Automated Exfiltration (T1020) with moderate to high confidence (75%), supported by evidence indicating vendor (FBCS) security failure implied automated/data-processing exposure. Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (30%), supported by evidence indicating fBCS went bankrupt before disclosing the breach (potential data loss) and Resource Hijacking (T1496) with moderate to high confidence (70%), supported by evidence indicating identity theft risk such as High (personal data exposed). Under the Defense Evasion tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with moderate confidence (60%), supported by evidence indicating vendor (FBCS) security failure (possible misuse of legitimate access) and Disable or Modify Tools: Impair Defenses (T1562.001) with moderate confidence (50%), supported by evidence indicating lack of oversight (implied inadequate security controls). Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with moderate confidence (65%), supported by evidence indicating vendor security failure (implied poor credential storage/practices). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
