Threats Affecting Germany

Global law enforcement, including agencies from the Netherlands, Canada, United States, and Germany, coordinated Operation Endgame to disrupt TA569, a prominent cybercriminal group tracked since 2018. The operation targeted SocGholish infrastructure, taking down over 100 servers and domains while remediating 14,971 compromised websites. TA569 pioneered web inject techniques using fake browser updates to distribute malware, often leading to ransomware attacks. The group compromised high-traffic websites across multiple industries, affecting millions of visitors globally. Their attack chains involved traffic distribution systems like Keitaro TDS and ParrotTDS, delivering GhoLoader payloads that could lead to ransomware deployment in enterprise environments. Law enforcement actions included server disruption and website disinfection, significantly impacting the threat actor's operations, infrastructure, and reputation within the cybercriminal ecosystem.

Since late 2025, cybercriminals have been exploiting Wallpaper Engine, a popular live wallpaper application on Steam, to distribute malware through Steam Workshop. Attackers target primarily Chinese and Russian gamers by embedding malicious code within application wallpapers shared on the platform. These compromised wallpapers deliver various malware types including infostealers, backdoors, crypto miners, and ransomware. One analyzed sample dropped DarkKomet backdoor while hijacking Steam sessions to steal account credentials. The malware modifies system libraries to locate Steam installations and exfiltrate data to attacker-controlled servers. Compromised accounts are then used to upload additional malicious wallpapers. The diverse malware families suggest multiple independent hacking groups are exploiting this distribution method. Infected wallpapers received thousands of downloads before removal, with 89% of infections occurring in China.

A sophisticated smishing and phishing operation active since the second half of 2025 has impersonated over 267 brands across 72 countries, with particular concentration in Latin America. The campaign generated 4,389 phishing domain instances, with Mexico accounting for 1,851 cases. Telecommunications is the most targeted sector with 1,754 instances, followed by financial services and consumer rewards programs. The operation employs fake Cloudflare error pages as decoys, revealing malicious content only to victims matching specific geofencing and mobile device criteria. Data exfiltration occurs through encrypted WebSocket channels using binary encoded payloads. Approximately 30% of infrastructure is hosted on Tencent Cloud and Alibaba US servers, fronted by Cloudflare to mask hosting IPs. The attack chain progresses from SMS lures through progressive credential harvesting, ultimately capturing complete credit card details including CVV codes.
