Summary
Anonymous hackers targeted companies owned by the Czech Finance Minister through DDoS attacks under #OpBlokada, opposing new legislation granting authorities power to block unlicensed gambling websites. The group claimed the law established dangerous internet censorship precedents, warning it could enable broader state control over online content. While the minister advocated the policy as a tool against tax evasion in gambling, the collective denounced it as an overreach of governmental authority. Initial disruptions were brief but signaled potential future actions against entities supporting the measure.

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, specifically targeted Agrofert, Hyza, Cepro, Preol, Penam, Uniles, and Wotan Forest – all part of Babiš's corporate portfolio. These attacks were intentionally brief, described by the group as short-lived demonstrations rather than sustained disruptions. Anonymous justified its actions as a protest against new online gambling legislation championed by Babiš, which granted the Czech government authority to block unlicensed gambling websites nationwide. The group released a translated YouTube statement warning that the law established dangerous precedents for internet censorship, arguing it provided the Finance Ministry "almost unlimited authority" to create blocklists that could expand beyond gambling sites. They characterized the gambling restrictions as a trial run for broader online content suppression under future legislation.
The immediate operational impact was limited to temporary disruption of the targeted companies' online services during the DDoS events. Anonymous explicitly threatened follow-up attacks in subsequent days, though the provided source material does not confirm whether these occurred. The Czech government had previously defended the gambling law as a necessary measure to combat tax evasion within the industry, contrasting sharply with Anonymous's framing of the policy as censorship infrastructure. No technical details regarding attack mitigation, forensic findings, or official incident response protocols were disclosed in the available reporting. The incident highlighted tensions between government regulatory efforts targeting illicit online activities and hacktivist concerns about expanded state control over internet access.
