Description

The Czech public television broadcaster Česká televize (ČT) experienced a series of disruptive cyber attacks targeting its online services during the 2022 Winter Olympics in Beijing. The incident began on the morning of February 11, 2022, when a cyber attack disabled the websites of ČT's sports channel during its live broadcast of the Czech Republic versus Switzerland men's ice hockey Olympic match. This forced the broadcaster to relocate its streaming service to an emergency backup page to maintain coverage. The February 11 attack represented an escalation in an ongoing campaign, as ČT had first reported service disruptions the previous Friday (February 4) just prior to its scheduled broadcast of the Olympic opening ceremony. Subsequent attacks continued to coincide with live coverage of events featuring Czech athletes throughout the Games.

The attacks employed distributed denial-of-service (DDoS) techniques that overwhelmed ČT's web infrastructure through massive volumes of artificial traffic. This systematic targeting specifically disrupted digital streaming services during critical Olympic events involving Czech competitors, indicating deliberate timing to maximize visibility. ČT's immediate response involved activating contingency broadcasting arrangements, including redirecting viewers to alternative online platforms when primary services became unavailable. The broadcaster maintained public communication through its Twitter account, confirming each service disruption and recovery effort. While the attacks caused significant operational challenges, ČT maintained television broadcasts through traditional transmission methods unaffected by the digital assaults. The repeated nature of these incidents demonstrated persistent targeting of ČT's Olympic coverage infrastructure throughout the Games period.
