On Sunday afternoon, the National Computer Incident Response Center of Belarus (CERT) reported that the servers of the State Security Committee (KGB), the country’s spy agency, had come under sustained attack. The Internal Affairs Ministry’s website and servers had also been affected by what CERT called “a large wave” of cyberattacks. These were first noticed on Saturday, but continued well into the evening of Sunday, according to reports. Other government websites and services were subjected to distributed denial of service (DDoS) attacks, during which online servers crashed after being flooded with requests for information.

Meanwhile, Internet and cell phone users reported having difficulty accessing popular websites like Google, and social media services, including Telegram and Signal. Internet-based cell phone service was almost completely down throughout the country by Sunday afternoon. Beltelecom, the state-owned telephone service provider, said its systems were “experiencing interruptions in access” and “congestion of channels due to foreign traffic in large quantities”. It added that its technicians had not yet determined “whether people or machines” were behind the disruptions in service.

Late last month, the Belarusian secret services arrested 33 Russian citizens, who were allegedly members of the Wagner Group, a Kremlin-backed private military firm. The government of Belarus accused the group of trying to subvert the presidential elections on behalf of Moscow. The 33 Russians were charged with terrorism against the state. Russia has denied claims by the Belarussian government that it is behind an effort to destabilize the former Soviet Republic.
