Several Polish news websites on Thursday were targeted by widespread denial-of-service attacks.
The digitalisation minister who confirmed the attack stated it could be the action of Russian hacking groups.
Since Russia’s invasion of Ukraine, Warsaw has positioned itself as one of the country’s staunchest supporters, and Poland claims to face Russian attempts to destabilise the situation on a regular basis.
Moscow has long denied conducting hacking attacks.
DDoS attacks work by sending massive amounts of internet traffic to specific servers in an attempt to bring them down.
“Having information that such attacks are being prepared, we immediately informed all interested editorial offices so that they had the opportunity to react to this situation,” Janusz Cieszynski was quoted as saying by state-run news agency PAP.
When asked if Russian groups were behind the attacks, Cieszynski responded, “We have such information.”
The Russian foreign ministry did not respond quickly to an email requesting comment.
The websites of daily newspapers Gazeta Wyborcza, Rzeczpospolita, and Super Express were among those affected, according to PAP.
