JLR Breach Incident Score: Analysis & Impact (JAG0092700111825)

In this Rankiteo incident briefing, we review the JLR breach identified under incident ID JAG0092700111825.

The analysis begins with a detailed overview of JLR's information like the linkedin page: https://www.linkedin.com/company/tata-consultancy-services, 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 825 and after the incident was 825 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 27 October 2023, Jaguar Land Rover (JLR) disclosed Cyberattack, Supply Chain Disruption and Social Engineering issues under the banner "Cyberattack on Jaguar Land Rover Disrupts Production and Supply Chain".

Jaguar Land Rover (JLR) experienced a cyberattack in late summer (September 2023) that disrupted automotive production for weeks, leading to a 24% revenue drop in Q2 FY2024.

The disruption is felt across the environment, affecting Production systems and Supply chain networks, plus an estimated financial loss of $735M (post-tax loss for Q2).

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like System shutdown and Phased restart, while recovery efforts such as Financing solution for suppliers and Calibrated operational resumption continue, and stakeholders are being briefed through Earnings call disclosure (2023-10-27) and Public statements.

The case underscores how Ongoing (threat actor linked to prior attacks but not fully identified), teams are taking away lessons such as Need for better third-party risk monitoring in supply chains (per Moody’s report), Importance of limiting information sharing with suppliers and Ranking suppliers by cyber risk exposure, and recommending next steps like Enhance supply chain cybersecurity resilience, Implement stricter access controls and supplier vetting and Develop contingency plans for critical production periods, with advisories going out to stakeholders covering UK government loan package for suppliers and Moody’s risk assessment for European manufacturers.

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 Phishing: Spearphishing Link (T1566.002) with moderate to high confidence (85%), with evidence including attack vector such as Social Engineering, and entry point such as Suspected social engineering and Valid Accounts: Cloud Accounts (T1078.004) with moderate to high confidence (75%), with evidence including high value targets such as Production systems, Supply chain data, and supply chain disruption via compromised systems. Under the Impact tactic, the analysis identified Endpoint Denial of Service: Application or System Exploitation (T1499.004) with high confidence (95%), with evidence including containment measures such as System shutdown, downtime such as Weeks (September to early October 2023), and production halt for weeks and Data Destruction (T1485) with moderate to high confidence (70%), with evidence including systems affected such as Production systems, Supply chain networks, and no explicit data exfiltration but prolonged operational halt. Under the Lateral Movement tactic, the analysis identified Remote Services: SSH (T1021.004) with moderate confidence (65%), with evidence including 5,000+ supplier organizations impacted via interconnected systems, and supply chain networks affected. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate confidence (60%), with evidence including threat group linked to the April 2023 Marks & Spencer attack, and no explicit C2 details but implied persistence via supply chain. Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate confidence (55%), with evidence including no forensic details, but phased restart suggests potential cleanup, and containment measures such as System shutdown. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
