Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

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 Valid Accounts: Cloud Accounts (T1078.004) with moderate to high confidence (80%), supported by evidence indicating exploiting exposed credentials and creating rogue IAM accounts. Under the Credential Access tactic, the analysis identified Steal Application Access Token (T1528) with moderate to high confidence (70%), supported by evidence indicating aWS cloud environments targeted via exposed credentials and Brute Force: Password Guessing (T1110.001) with moderate confidence (50%), supported by evidence indicating potentially exposed AWS credentials (implied). Under the Privilege Escalation tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with moderate to high confidence (80%), supported by evidence indicating rogue IAM accounts created to escalate privileges. Under the Collection tactic, the analysis identified Data from Cloud Storage (T1213.003) with high confidence (90%), supported by evidence indicating exfiltrated 1M+ customer records including PII and payment data. Under the Exfiltration tactic, the analysis identified Transfer Data to Cloud Account (T1537) with high confidence (90%), supported by evidence indicating data exfiltration confirmed; sample to be released if demands unmet. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating extortion group; no ransomware encryption confirmed and Financial Theft (T1657) with moderate to high confidence (70%), supported by evidence indicating payment card details and payment histories exposed. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
