Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the SonicWall breach identified under incident ID SON1785487061.
The analysis begins with a detailed overview of SonicWall's information like the linkedin page: https://www.linkedin.com/company/sonicwall, the number of followers: 128529, the industry type: Computer and Network Security and the number of employees: 1958 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 100 and after the incident was 100 with a difference of 0 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 SonicWall and their customers.
On 31 May 2025, a cybersecurity incident called "UK Manufacturing Hit Hardest by Ransomware as Attacks Surge 28%" came to light.
UK manufacturing has emerged as the most targeted sector for ransomware attacks, with 1.84 million incidents recorded between January and May 2025.
The disruption is felt across the environment, affecting SCADA, MES and ERP systems.
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as Manufacturers face unique challenges in securing industrial environments due to operational technology (OT) systems tied to physical production processes, which are difficult to patch without disrupting operations. The adoption of internet-facing tools has expanded the attack surface without equivalent security controls.
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 Exploit Public-Facing Application (T1190) with high confidence (90%), supported by evidence indicating apache Log4j flaws, React Server Components RCE vulnerabilities exploited and External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating internet-facing tools, such as customer portals and digital dashboards. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (80%), supported by evidence indicating filecoder malware family attributed to 1.79 million ransomware hits. Under the Persistence tactic, the analysis identified Supply Chain Compromise (T1195) with lower confidence (40%), supported by evidence indicating legacy infrastructure risks due to unpatched systems. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (70%), supported by evidence indicating sCADA, MES, and ERP systems exposed via unpatched vulnerabilities. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating persistent probing of industrial networks (15.8M intrusion attempts) and Obfuscated Files or Information (T1027) with moderate to high confidence (70%), supported by evidence indicating filecoder malware family used for ransomware activity. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (95%), supported by evidence indicating filecoder malware encrypts data; ransomware surge targeting UK manufacturing and Defacement (T1491) with lower confidence (30%), supported by evidence indicating production downtime and supply chain chaos implied. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate confidence (50%), supported by evidence indicating extortion motivation suggests possible data exfiltration. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
