Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the MGM breach identified under incident ID MOVBRIMGM1770602315.
The analysis begins with a detailed overview of MGM's information like the linkedin page: https://www.linkedin.com/company/mgm, the number of followers: 128086, the industry type: Entertainment Providers and the number of employees: 4969 employees
After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 779 and after the incident was 758 with a difference of -21 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on MGM and their customers.
British Airways recently reported "2023: A Record-Breaking Year for Ransomware as Attacks Surge Past $1 Billion in Extorted Payments", a noteworthy cybersecurity incident.
2023 marked a dramatic resurgence in ransomware activity, with cybercriminals extorting over $1 billion in cryptocurrency payments—the highest annual total on record.
The disruption is felt across the environment, and exposing Millions of records, with nearly Millions records at risk, plus an estimated financial loss of > $1 billion (ransom payments alone).
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing (some groups disrupted, others active), teams are taking away lessons such as Ransomware actors are highly adaptable, exploiting zero-day vulnerabilities, supply chain attacks, and RaaS models to maximize profits. Law enforcement disruptions can significantly reduce ransom payments, but the threat remains persistent and evolving, and recommending next steps like Enhance supply chain security, Improve zero-day vulnerability patching and Strengthen law enforcement collaboration.
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.
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 Supply Chain Compromise (T1195) with high confidence (90%), supported by evidence indicating mOVEit file transfer software breach, exploited by Cl0p ransomware group and Exploit Public-Facing Application (T1190) with high confidence (90%), supported by evidence indicating mOVEit file transfer software zero-day vulnerability exploited. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (80%), supported by evidence indicating zero-day vulnerability in MOVEit allowed attackers to compromise organizations. Under the Persistence tactic, the analysis identified External Remote Services (T1133) with moderate to high confidence (70%), supported by evidence indicating supply chain attack on MOVEit file transfer software enabled ongoing access. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (70%), supported by evidence indicating zero-day vulnerability likely used to escalate privileges in MOVEit breach. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate confidence (60%), supported by evidence indicating ransomware groups rebrand (e.g., Trickbot, Royal ransomware, 3AM) to evade detection and Virtualization/Sandbox Evasion (T1497) with moderate confidence (50%), supported by evidence indicating raaS models enable less skilled attackers to deploy evasive ransomware. Under the Credential Access tactic, the analysis identified Adversary-in-the-Middle (T1557) with moderate confidence (60%), supported by evidence indicating supply chain attacks likely enabled access to credentials in MOVEit breach. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating cl0p shifted to data exfiltration, implying discovery of sensitive files. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating millions of records exposed, including PII and sensitive corporate data. Under the Command and Control tactic, the analysis identified Application Layer Protocol (T1071) with moderate to high confidence (70%), supported by evidence indicating ransomware groups (e.g., Cl0p) exfiltrated data over C2 channels. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating cl0p shifted to data exfiltration over encryption, generating $100M+ in ransoms and Exfiltration Over Web Service (T1567) with moderate to high confidence (70%), supported by evidence indicating data exfiltrated from compromised organizations (e.g., British Airways, BBC). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (80%), supported by evidence indicating aLPHV-BlackCat and other strains encrypted data in some cases, Data Destruction (T1485) with moderate confidence (50%), supported by evidence indicating ransomware attacks caused significant operational impact (e.g., MGM Resorts), and Defacement (T1491) with lower confidence (40%), supported by evidence indicating high-profile attacks (e.g., British Airways, BBC) damaged brand reputation. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
