GeoServer Exploits, PolarEdge, Gayfemboy Expand Cybercrime

🛡️ Cybersecurity teams report coordinated campaigns exploiting exposed infrastructure and known flaws to monetize or weaponize compromised devices. Attackers have abused CVE-2024-36401 in GeoServer to drop lightweight Dart binaries that monetize bandwidth via legitimate passive-income services, while the PolarEdge botnet and Mirai-derived gayfemboy expand relay and DDoS capabilities across consumer and enterprise devices. Separately, TA-NATALSTATUS targets unauthenticated Redis instances to install stealthy cryptominers and persistence tooling.

Resurgence of Mirai-Based IoT Malware: Gayfemboy Campaign

🛡️ FortiGuard Labs reports the resurgence of a Mirai-derived IoT malware family, publicly known as “Gayfemboy,” which reappeared in July 2025 targeting vulnerabilities in DrayTek, TP-Link, Raisecom, and Cisco devices. The campaign delivers UPX-packed payloads via predictable downloader scripts named for product families and uses a modified UPX header and architecture-specific filenames to evade detection. At runtime the malware enumerates processes, kills competitors, implements DDoS and backdoor modules, and resolves C2 domains through public DNS resolvers to bypass local filtering. FortiGuard provides AV detections, IPS signatures, and web-filtering blocks; organizations should patch and apply network defenses immediately.

Oregon Man Charged Over Rapper Bot DDoS Service Probe

🔒 Federal agents arrested 22‑year‑old Ethan J. Foltz of Springfield, Ore., on Aug. 6, 2025, on suspicion of operating Rapper Bot, a global IoT botnet rented to extortionists for DDoS attacks. The complaint alleges Rapper Bot routinely generated attacks exceeding 2 terabits per second and at times surpassed 6 Tbps, including an attack tied to intermittent outages on Twitter/X. Investigators traced control infrastructure and payments through an ISP subpoena, PayPal records and Google data, recovered Telegram chats with a co‑conspirator known as 'Slaykings,' and say Foltz wiped logs regularly to hinder attribution. He faces one count of aiding and abetting computer intrusions, carrying a maximum statutory term of 10 years.
