Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Rolls-Royce breach identified under incident ID JOHROLERI1772202424.
The analysis begins with a detailed overview of Rolls-Royce's information like the linkedin page: https://www.linkedin.com/company/rolls-royce, the number of followers: 1834160, the industry type: Industrial Machinery Manufacturing and the number of employees: 31122 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 822 and after the incident was 788 with a difference of -34 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 Rolls-Royce and their customers.
On 23 February 2026, Rolls-Royce disclosed Credential Stuffing issues under the banner "Credential Stuffing Campaign Exploits Stolen Employee Logins to Breach Corporate Networks".
A sophisticated credential stuffing campaign targeting corporate Single Sign-On (SSO) gateways, particularly F5 BIG-IP interfaces, leveraged stolen employee credentials harvested from infostealer malware infections to gain network access.
The disruption is felt across the environment, affecting ADFS, Security Token Services (STS) and OWA portals, and exposing Employee credentials, potential access to internal systems, with nearly 70 unique credentials records at risk.
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing, teams are taking away lessons such as The incident underscores the critical importance of multi-factor authentication (MFA) and the risks posed by infostealer malware in enabling credential stuffing attacks. Identity is now the new perimeter, and stolen credentials can bypass traditional security measures, and recommending next steps like Implement multi-factor authentication (MFA) for all corporate systems, especially SSO and remote access gateways, Monitor for infostealer malware infections on employee devices and Enforce strict password policies and regular credential rotation.
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 Valid Accounts (T1078) with high confidence (95%), supported by evidence indicating 77% of the 70 unique credentials matched known infostealer infection logs, Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating targeting corporate Single Sign-On (SSO) gateways particularly F5 BIG-IP interfaces, and External Remote Services (T1133) with moderate to high confidence (85%), supported by evidence indicating credentials repurposed against ADFS, Security Token Services (STS), and OWA portals. Under the Credential Access tactic, the analysis identified Credentials from Password Stores (T1555) with high confidence (90%), supported by evidence indicating credentials harvested from infostealer malware infections on employee devices and Brute Force: Credential Stuffing (T1110.004) with high confidence (95%), supported by evidence indicating sophisticated credential stuffing campaign targeting corporate SSO gateways. Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with moderate to high confidence (70%), supported by evidence indicating automated login attempts using credentials. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating single stolen ADFS password could unlock VPNs, SSO portals, or remote access gateways. Under the Defense Evasion tactic, the analysis identified Subvert Trust Controls: Install Root Certificate (T1553.004) with moderate confidence (60%), supported by evidence indicating compromised Fortinet FortiGate-60E firewall with self-signed SSL certificate and Valid Accounts (T1078) with moderate to high confidence (85%), supported by evidence indicating stolen credentials used to bypass traditional security measures. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate to high confidence (70%), supported by evidence indicating potential access to internal systems via stolen credentials and Remote Services: SSH (T1021.004) with moderate confidence (60%), supported by evidence indicating credentials repurposed against ADFS, STS, and OWA portals. Under the Collection tactic, the analysis identified Data from Information Repositories (T1213) with moderate to high confidence (70%), supported by evidence indicating potential access to internal systems via stolen credentials. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating log-to-Lead pipeline where infostealer logs are aggregated and sold. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
