Cisco Talos documents an ongoing Gamaredon campaign (since at least Nov 2024) targeting Ukrainian users with war-themed LNK-based phishing lures that run PowerShell to download a ZIP containing a DLL-sideloaded Remcos backdoor; the report provides TTPs, hosting infrastructure (servers in Russia and Germany, ISPs GTHost/HyperHosting), a C2 IP (146.185.233.96:6856), sample filenames, and IOCs in a GitHub repository.
