On 07 August 2024, Road Traffic Safety Directorate (CSDD) disclosed Data Breach issues under the banner "Latvia’s Road Traffic Safety Directorate Suffers Major Cyberattack Amid Monitoring Failures".
Latvia’s Road Traffic Safety Directorate (CSDD) was hit by a significant cyberattack between August 7 and 8, resulting in the theft of personal data belonging to 1.2 million individuals and records from 200,000 legal entities spanning 18 years of payment transactions.
The disruption is felt across the environment, affecting CSDD payment transaction systems, and exposing Personal data of 1.2 million individuals and records from 200,000 legal entities, with nearly 1.4 million (1.2M individuals + 200K legal entities) records at risk.
In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Breach contained within hours by CSDD’s cybersecurity team, and stakeholders are being briefed through Public disclosure by CSDD Chairman and Prime Minister.
The case underscores how Ongoing (accelerated internal investigation by Transport Minister), teams are taking away lessons such as Failure of third-party monitoring provider (Tet) to detect the breach; need for improved cybersecurity oversight in public-sector infrastructure, and recommending next steps like Strengthen monitoring agreements with cybersecurity agencies like CERT.LV, Enhance internal cybersecurity capabilities and Review third-party vendor contracts for accountability, with advisories going out to stakeholders covering Prime Minister holds CSDD Management and Supervisory Boards accountable; potential foreign state involvement suspected.
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.
