Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Cloudflare breach identified under incident ID SENCLO1786454995.
The analysis begins with a detailed overview of Cloudflare's information like the linkedin page: https://www.linkedin.com/company/cloudflare, the number of followers: 1188930, the industry type: Computer and Network Security and the number of employees: 7336 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 494 and after the incident was 483 with a difference of -11 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 Cloudflare and their customers.
Cloudflare recently reported "Ghostjacking: AI Agents Turn Security Logs into Attack Vectors", a noteworthy cybersecurity incident.
Researchers at Tenet Security unveiled a new attack technique called Ghostjacking at DEF CON 34, exposing a critical flaw in AI-driven security workflows.
The disruption is felt across the environment, affecting DNS, Email routing and Cloud credentials.
In response, and began remediation that includes Isolating read-only investigations from write operations, Enforcing human approval for high-impact changes and Treating all externally influenced logs as untrusted input.
The case underscores how teams are taking away lessons such as The findings highlight a broader 'confused deputy' problem in AI systems, where agents granted high-level access to observability, ticketing, and cloud management tools fail to distinguish between data and hidden instructions. Traditional security tools like EDR, WAFs, and IAM systems may overlook these attacks, as they appear as valid actions by authorized identities, and recommending next steps like Stricter controls for AI agent operations, Isolating read-only investigations from write operations and Enforcing human approval for high-impact changes.
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 exploits trusted operational data such as blocked web requests and Phishing: Spearphishing Attachment (T1566.001) with moderate confidence (50%), supported by evidence indicating attacker-controlled content in logs as legitimate instructions. Under the Execution tactic, the analysis identified Command and Scripting Interpreter: Visual Basic (T1059.005) with lower confidence (40%), supported by evidence indicating aI agents execute malicious actions within enterprise environments and User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating aI assistant...modified DNS records to redirect traffic. Under the Privilege Escalation tactic, the analysis identified Abuse Elevation Control Mechanism: Bypass User Account Control (T1548.002) with moderate to high confidence (80%), supported by evidence indicating privilege escalation via agent configuration changes and Valid Accounts: Cloud Accounts (T1078.004) with high confidence (90%), supported by evidence indicating appearing as an authorized API call from a trusted identity. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating traditional security tools...may overlook these attacks and Masquerading: Masquerade Task or Service (T1036.004) with moderate to high confidence (80%), supported by evidence indicating appearing as valid actions by authorized identities. Under the Credential Access tactic, the analysis identified Steal Application Access Token (T1528) with high confidence (90%), supported by evidence indicating gain control over...cloud credentials, enabling account takeovers and Unsecured Credentials: Container API (T1552.007) with moderate to high confidence (70%), supported by evidence indicating aI agents granted high-level access to...cloud management tools. Under the Lateral Movement tactic, the analysis identified Use Alternate Authentication Material: Application Access Token (T1550.001) with moderate to high confidence (80%), supported by evidence indicating propagating malicious remediations across systems. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate confidence (60%), supported by evidence indicating redirect traffic to attacker-controlled infrastructure. Under the Impact tactic, the analysis identified Account Access Removal (T1531) with moderate to high confidence (70%), supported by evidence indicating account takeovers without triggering conventional security alerts and Network Denial of Service (T1498) with moderate confidence (50%), supported by evidence indicating modified DNS records to redirect traffic. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
