The China-aligned APT group Webworm has updated its toolset in 2025, shifting focus to European and South African targets. The group deployed two new custom backdoors, EchoCreep and GraphWorm, which abuse Discord and the Microsoft Graph API respectively for command and control. Additionally, Webworm utilizes a complex network of custom proxy tools and compromised infrastructure, including GitHub and Amazon S3, to stage payloads and exfiltrate data.
The US Department of Justice, alongside international authorities and industry partners including Akamai, successfully disrupted the Aisuru and Kimwolf IoT botnets. These hyper-volumetric botnets compromised up to 4 million IoT devices to launch record-breaking DDoS attacks exceeding 30 Tbps, which were used to cripple internet infrastructure and extort victims.
A coordinated international law enforcement and private sector operation successfully disrupted Tycoon 2FA, a prominent Phishing-as-a-Service (PhaaS) platform. The service enabled low-skill attackers to bypass multi-factor authentication (MFA) using adversary-in-the-middle (AitM) techniques to harvest credentials and session cookies, which were subsequently used for BEC and ransomware attacks.
