Poland has detected a significant malware attack against its government institutions, linked to the Russian-associated APT28 cyber group.

APT28 utilized deceptive emails with links to legitimate websites for malicious data-gathering on infected hosts.

The alert follows international condemnation by NATO, the EU, and European nations of APT28's cyber espionage, which recently exploited a Microsoft Outlook zero-day vulnerability.

With a history of operations since 2007, APT28 has engaged in cyber attacks on governments, military entities, and security agencies, including interference in the 2016 US Presidential election.

The United States and the European Union have publicly denounced APT28's cyber espionage and have urged Russia to cease these hostile activities.
