The portal uses a custom masterserver list so you can find active games. Altering a program's network behavior is a classic "trojan-like" trait, even if the intent is harmless.

CS servers often redirect players to a sv_downloadurl (a web server) to download custom maps, models, or sounds. The Strogino malware replaces legitimate URLs with a malicious one (e.g., http://strogino-cs-portal[.]ru/game/res/ ). Instead of .bsp maps, the server pushes:
