Summary
Anonymous hackers launched DDoS attacks against multiple companies, including Preol, owned by the Czech Finance Minister in response to controversial online gambling legislation. The hacktivist collective criticized the law as enabling government overreach and potential internet censorship frameworks, warning that blocking unlicensed gambling sites could expand to broader content restrictions. The short-lived operational disruptions under #OpBlokada served as a protest against granting authorities enhanced powers to blacklist websites, with the group threatening escalated actions. Officials defended the law as an anti-tax evasion measure for the gambling industry.

Description
On August 1, 2016, the Czech and Slovakian branches of the Anonymous hacker collective launched distributed denial-of-service (DDoS) attacks against multiple companies owned by Czech Finance Minister Andrej Babiš. The operation, designated #OpBlokada, targeted Agrofert, Hyza, Cepro, Preol, Penam, Uniles, and Wotan Forest. These attacks were explicitly motivated by opposition to new online gambling legislation championed by Babiš, which granted the Czech government authority to block unlicensed gambling websites nationwide. Anonymous framed the law as a dangerous precedent for broader internet censorship, warning in a YouTube statement that it established a "state blacklist" mechanism that could expand to other domains under the Finance Ministry's "unlimited authority to censor the internet." The group characterized the DDoS incidents as short-lived demonstrations intended to signal their dissent rather than cause prolonged disruption, while threatening escalated actions in subsequent days.
The attacks occurred hours after the controversial law's implementation, which the Czech government defended as necessary to combat tax evasion within the gambling industry. Anonymous disputed this rationale, asserting the legislation served as a testing ground for future content-blocking regimes. Immediate operational impacts were limited to temporary service disruptions across the targeted corporate websites, with no reported data breaches or infrastructure damage. No formal containment measures or technical responses from the affected entities were documented in available reporting. The incident drew media attention primarily through Anonymous' YouTube manifesto and local news coverage, amplifying debates about internet governance and state surveillance powers. Babiš's companies resumed normal operations following the brief attacks, though the collective's threats of follow-on actions introduced uncertainty regarding potential future disruptions.
