Tet: CSDD cyberattack was targeted and professionally executed
Telecom company Tet has launched an investigation into the CSDD cyberattack and already implemented additional security measures, saying the breach appeared highly targeted and professional.
Following a cyberattack on the Road Traffic Safety Directorate (CSDD) on the night of August 8, in which attackers obtained data on roughly 1.2 million individuals and around 200,000 legal entities, technology company Tet has begun an in-depth investigation into the incident. The stolen information relates to payments made to CSDD over the past 18 years, and the State Police have already opened a criminal case.
Tet board chairman Uldis Tatarčuks said the attack appears, at first glance, to have been carried out in a highly targeted and professional manner. The company stressed that both CSDD and its clients are victims of a serious cybersecurity incident, which is being treated as a top priority. Tet said it can only provide a full account of what happened once a detailed technical analysis is complete.
Security improvements already in place
To reduce further risks, Tet has already implemented several additional measures — all available systems and network traffic have been connected to a SIEM monitoring solution, security monitoring thresholds have been reviewed and refined, in-depth analysis of system logs has been carried out, and monitoring across the entire infrastructure has been strengthened. The company says these steps have already paid off, with several new malicious activities detected and addressed in recent days before causing further harm.
The investigation continues, with Tet's team analyzing available technical data and the timeline of events to determine the precise circumstances of the incident. The company is cooperating closely with CSDD, the national cybersecurity institution CERT.LV, and other involved parties, while acknowledging that CSDD's current priority is supporting its own clients and managing challenges tied to a change in its leadership.
Tet is urging organizations and individuals to stay vigilant about cybersecurity — using strong, unique passwords, changing them regularly, enabling multi-factor authentication, and being cautious of suspicious emails, links and other potential fraud attempts.
