Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Fortinet breach identified under incident ID SONFOR1778660813.
The analysis begins with a detailed overview of Fortinet's information like the linkedin page: https://www.linkedin.com/company/fortinet, the number of followers: 1232151, the industry type: Computer and Network Security and the number of employees: 15789 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 738 and after the incident was 376 with a difference of -362 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 Fortinet and their customers.
A newly reported cybersecurity incident, "Ransomware Evolves into Stealthier, More Destructive Threat in 2026", has drawn attention.
In 2026, ransomware attacks have shifted from opportunistic strikes to highly calculated, multi-stage operations, adapting to global anti-ransomware efforts.
The disruption is felt across the environment, affecting Manufacturing sector and Enterprise hardware (Fortinet, SonicWall, Cisco), and exposing Sensitive data (encryptionless extortion), plus an estimated financial loss of $18 billion (manufacturing sector alone).
Formal response steps have not been shared publicly yet.
Overall, the incident is a reminder of why proactive monitoring and strong governance matter.
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 moderate confidence (60%), supported by evidence indicating enterprise hardware vulnerabilities (Fortinet, SonicWall, Cisco) and Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating exploitation of trusted system components. Under the Defense Evasion tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (80%), supported by evidence indicating bring Your Own Vulnerable Driver (BYOVD) technique, Impair Defenses: Disable or Modify Tools (T1562.001) with high confidence (90%), supported by evidence indicating eDR killers terminate monitoring agents using legitimate signed drivers, and Masquerading (T1036) with moderate to high confidence (70%), supported by evidence indicating use of legitimate, signed drivers to evade detection. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (80%), supported by evidence indicating bYOVD technique to disable security tools. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating post-quantum cryptography (ML-KEM/Kyber1024) ensures file recovery impossible and Inhibit System Recovery (T1490) with moderate to high confidence (70%), supported by evidence indicating ransomware developers future-proofing malware with strong encryption. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating encryptionless extortion involves stealing sensitive data and Exfiltration Over Web Service (T1567) with moderate confidence (60%), supported by evidence indicating threatening public disclosure of stolen data. Under the Credential Access tactic, the analysis identified Adversary-in-the-Middle (T1557) with moderate confidence (50%), supported by evidence indicating exploitation of trusted system components. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
