In this Rankiteo incident briefing, we review the Winsupply breach identified under incident ID WIN3532335111125.

The analysis begins with a detailed overview of Winsupply's information like the linkedin page: https://www.linkedin.com/company/winsupply, the number of followers: 43474, the industry type: Wholesale and the number of employees: 1855 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 757 and after the incident was 663 with a difference of -94 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 Winsupply and their customers.

On 01 September 2023, a cybersecurity incident called "Russian National Pleads Guilty as Initial Access Broker for Yanluowang Ransomware Group (2021–2022)" came to light.

A 2023 indictment revealed that a Russian national acted as an initial access broker (IAB) for the Yanluowang ransomware group, facilitating high-impact intrusions into at least eight U.S.-based companies across manufacturing, technology services, and logistics sectors between...

The disruption is felt across the environment, affecting True, and exposing True.

In response, teams activated the incident response plan.

The case underscores how Ongoing (Sentencing Pending for IAB), teams are taking away lessons such as Initial access brokers (IABs) play a critical role in scaling ransomware operations by separating breach and deployment phases, Organizations must prioritize early detection of IAB activity to prevent ransomware payload delivery and Ransomware-as-a-service (RaaS) models rely on compartmentalized roles, requiring holistic defense strategies, and recommending next steps like Implement multi-factor authentication (MFA) for remote and administrative access, Monitor for suspicious lateral movement and privilege escalation and Patch enterprise software and infrastructure against known vulnerabilities.

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: Default Accounts (T1078.001) with moderate to high confidence (85%), with evidence including compromised Credentials (attack_vector), and entry point such as Compromised Credentials and Exploit Public-Facing Application (T1190) with high confidence (90%), with evidence including unpatched Software Vulnerabilities (attack_vector), and entry point such as Unpatched Vulnerabilities. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with moderate to high confidence (75%), with evidence including weak credential management (root_causes), and compromised Credentials (attack_vector). Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate to high confidence (70%), with evidence including monitor for suspicious lateral movement (recommendations), and backdoors established such as true. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (95%), with evidence including data exfiltration such as true, and sensitive Corporate Data (type_of_data_compromised). Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (80%), with evidence including data exfiltration such as true, and proprietary manufacturing processes, customer contracts, and employee records (description). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (99%), with evidence including yanluowang ransomware attack (title), data encryption such as true, and dual-extortion tactics (description) and Data Destruction (T1485) with moderate confidence (60%), supported by evidence indicating significant operational disruption, halting production lines (description). Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (70%), with evidence including backdoors established such as true (initial_access_broker), and lack of early detection for IAB activity (root_causes). Under the Persistence tactic, the analysis identified Server Software Component: Web Shell (T1505.003) with moderate to high confidence (75%), supported by evidence indicating backdoors established such as true (initial_access_broker). Under the Privilege Escalation tactic, the analysis identified Valid Accounts: Domain Accounts (T1078.002) with moderate to high confidence (80%), with evidence including monitor for suspicious ... privilege escalation (recommendations), and compromised Credentials (attack_vector). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
