JLR Breach Incident Score: Analysis & Impact (JAG5993659111725)

In this Rankiteo incident briefing, we review the JLR breach identified under incident ID JAG5993659111725.

The analysis begins with a detailed overview of JLR's information like the linkedin page: https://www.linkedin.com/company/tata-capital, the number of followers: 1298515, the industry type: Motor Vehicle Manufacturing and the number of employees: 41687 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 792 and after the incident was 792 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 JLR and their customers.

On 01 September 2025, Jaguar Land Rover (JLR) disclosed cyberattack, data breach and production disruption issues under the banner "Jaguar Land Rover Cyberattack and Data Breach (September 2025)".

Jaguar Land Rover (JLR) suffered a major cyberattack in September 2025, claimed by the group 'Scattered Lapsus$ Hunters,' which disrupted production, retail operations, and led to a data breach.

The disruption is felt across the environment, affecting production systems, retail operations and Solihull production plant, and exposing True, plus an estimated financial loss of £196 million (Q2 2025).

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like proactive shutdown of systems, while recovery efforts such as controlled restart of global applications continue, and stakeholders are being briefed through public statements on mitigation efforts and financial impact disclosure.

The case underscores how Ongoing (as of November 2025), with advisories going out to stakeholders covering UK government support package (£1.5 billion) to stabilize supply chain and operations.

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.

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 moderate to high confidence (70%), supported by evidence indicating threat actor Scattered Lapsus$ Hunters (known for abusing valid credentials) and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating disruption of car registration systems and parts supply chain suggests web-facing app compromise. Under the Impact tactic, the analysis identified Endpoint Denial of Service: Application or System Exploitation (T1499.004) with high confidence (95%), with evidence including halted production at Solihull plant, blocked car registrations, and disrupted parts supply and Data Encrypted for Impact (T1486) with moderate confidence (50%), supported by evidence indicating proactive shutdown of systems (possible ransomware-like disruption, though no ransom noted). 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 controlled restart of global applications implies lateral spread across internal networks. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (80%), supported by evidence indicating data breach confirmed; no details on exfiltration method, but Lapsus$ typically uses non-C2 channels. Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate confidence (60%), supported by evidence indicating proactive shutdown of systems (possible attacker cleanup or anti-forensic measures) and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating ~38 days downtime suggests persistent defense impairment. Under the Command and Control tactic, the analysis identified Proxy: External Proxy (T1090.004) with moderate to high confidence (70%), supported by evidence indicating lapsus$ historically uses proxies/VPNs for C2; no direct evidence but aligned with actor TTPs. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
