Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the AttackIQ breach identified under incident ID ATT1770818084.
The analysis begins with a detailed overview of AttackIQ's information like the linkedin page: https://www.linkedin.com/company/attackiq, the number of followers: 51379, the industry type: Computer and Network Security and the number of employees: 193 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 753 and after the incident was 642 with a difference of -111 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 AttackIQ and their customers.
On 01 August 2025, a cybersecurity incident called "Cephalus Ransomware Emerges as a Go-Based Threat Targeting Windows Networks" came to light.
A new ransomware strain, Cephalus, written in Go, has been active since at least June 2025, targeting Windows networks with a double-extortion tactic.
The disruption is felt across the environment, affecting Windows networks, and exposing Sensitive data stolen and leaked as proof.
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as Organizations with unsecured RDP access or weak credential hygiene are at high risk. Proactive monitoring of high-risk entry points is critical, and recommending next steps like Implement multi-factor authentication (MFA) for RDP services, Enhance credential hygiene and Monitor high-risk entry points.
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 External Remote Services (T1133) with high confidence (90%), supported by evidence indicating initial intrusions linked to exposed Remote Desktop Protocol (RDP) services and Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating frequently paired with stolen credentials. Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with moderate to high confidence (80%), supported by evidence indicating modifying registry keys via PowerShell (Add-MpPreference, Set-MpPreference) and Scheduled Task/Job: Scheduled Task (T1053.005) with high confidence (90%), supported by evidence indicating persistence through scheduled tasks (schtasks). Under the Persistence tactic, the analysis identified Scheduled Task/Job: Scheduled Task (T1053.005) with high confidence (90%), supported by evidence indicating persistence through scheduled tasks (schtasks). Under the Privilege Escalation tactic, the analysis identified Process Injection (T1055) with high confidence (90%), supported by evidence indicating process injection via VirtualAlloc and VirtualProtect. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with high confidence (95%), supported by evidence indicating tampering with Microsoft Defender disabling real-time protection, adding exclusions, Modify Registry (T1112) with high confidence (90%), supported by evidence indicating modifying registry keys via PowerShell (Add-MpPreference, Set-MpPreference), and Process Injection (T1055) with high confidence (90%), supported by evidence indicating process injection via VirtualAlloc and VirtualProtect. Under the Discovery tactic, the analysis identified System Information Discovery (T1082) with high confidence (90%), supported by evidence indicating environment reconnaissance using GetSystemInfo, GetUserNameW, File and Directory Discovery (T1083) with high confidence (90%), supported by evidence indicating file system enumeration with FindFirstFileW and FindNextFileW, and Process Discovery (T1057) with moderate to high confidence (80%), supported by evidence indicating createToolhelp32Snapshot used for environment reconnaissance. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating stealing sensitive data before encrypting files (double-extortion tactic). Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating attackers leak small proof datasets to demonstrate access. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (95%), supported by evidence indicating hybrid encryption scheme (AES-256 in CTR mode) for file encryption and Inhibit System Recovery (T1490) with high confidence (90%), supported by evidence indicating crippling recovery options, disabling defenses. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
