Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Brown-Forman breach identified under incident ID BRO1772396670.
The analysis begins with a detailed overview of Brown-Forman's information like the linkedin page: https://www.linkedin.com/company/brown-forman, the number of followers: 323706, the industry type: Beverage Manufacturing and the number of employees: 4733 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 718 and after the incident was 628 with a difference of -90 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 Brown-Forman and their customers.
Brown-Forman recently reported "Brown-Forman Hit by REvil Ransomware Attack: A Multi-Stage Extortion Scheme Unfolds", a noteworthy cybersecurity incident.
Brown-Forman, the Kentucky-based liquor conglomerate behind global brands like Jack Daniel’s and Finlandia vodka, fell victim to a sophisticated ransomware attack orchestrated by the REvil (Sodinokibi) cybercriminal gang.
The disruption is felt across the environment, and exposing 1TB of corporate data.
In response, moved swiftly to contain the threat with measures like Halted encryption stage.
The case underscores how teams are taking away lessons such as Ransomware attacks increasingly involve data theft as leverage, creating dual extortion threats. Refusing to pay ransom disrupts the extortion cycle but leaves stolen data at risk of exposure, and recommending next steps like Enhance network security controls, implement robust backup strategies, prepare for regulatory scrutiny, and develop incident response plans for ransomware attacks.
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 Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating escalating privileges to sysadmin-level access and Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating network infiltration, privilege escalation. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate confidence (60%), supported by evidence indicating trial malware deployments may have been used. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating sysadmin-level access. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating escalating privileges to sysadmin-level access. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with high confidence (90%), supported by evidence indicating disabled security controls to maximize their reach. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (70%), supported by evidence indicating sysadmin-level access suggests credential access. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with moderate to high confidence (80%), supported by evidence indicating mapped the infrastructure, identified backup locations. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating 1TB of corporate data stolen. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data theft (1TB stolen before encryption). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (70%), supported by evidence indicating attempted but prevented encryption stage. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
