Description
On January 19, 2024, the official website of the Canton of Basel-Stadt (www.bs.ch) experienced a distributed denial-of-service (DDoS) attack beginning at approximately 6:30 AM local time. The attack overwhelmed the website with a high volume of coordinated requests, temporarily rendering it inaccessible to users. Kantonal IT specialists immediately initiated countermeasures to restore service, though intermittent disruptions persisted during the initial response phase. By 9:00 AM, technicians successfully restored basic website functionality, allowing public access to resume. The attack specifically targeted the canton's primary web presence, though no subsidiary systems or data breaches were reported in available sources. Operational impacts included sporadic accessibility issues for approximately 2.5 hours during peak morning hours, affecting citizens seeking information through the government portal.

Technical teams maintained continuous monitoring following partial restoration, cautioning that residual performance degradation might occur despite implemented safeguards. No threat actor claimed responsibility, and investigation findings regarding the attack's origin remained undisclosed at the time of reporting. The incident required sustained defensive measures throughout the day to maintain service availability against potential follow-on attacks. Both the Canton of Basel-Stadt and City of Basel's joint IT infrastructure management confirmed the attack's containment to web services without evidence of lateral network movement or data compromise. Service disruptions constituted the sole confirmed operational impact, with no reports of secondary effects on departmental operations or data integrity.
