The Athens Urban Transport Organization (OASA) has restored its telematics system following a cyberattack on its information infrastructure. The attack caused a temporary blackout in real-time passenger information, though the organization's management confirmed that the situation is now being normalized.
Full Restoration and Operations
According to an official announcement, the telematics system is back in operation. Full functionality across the entire network is expected to be completely restored by the start of the morning shift on Monday, August 31, 2026.
Notably, while the information flow to electronic signs at stops and the mobile application was disrupted, the actual operation of bus and trolley routes continued as scheduled throughout the incident.
Response and Security Measures
Immediately following the detection of the breach, OASA activated its standard emergency procedures. The incident was reported to the following authorities:
- The National Cybersecurity Authority
- The National Electronic Attack Response Authority
The latter provided technical assistance to contain and mitigate the attack. It was clarified that the incident was strictly limited to the telematics infrastructure, with no impact detected on other IT systems belonging to the OASA Group or its subsidiaries.
OASA issued an apology to the commuting public for the inconvenience and expressed gratitude for their patience during the disruption.
