Law enforcement actions ranged from Europol's 193 arrests in a VaaS crackdown to multiple national detentions, while Apple and Google issued broad spyware alerts. Researchers flagged >10,000 Docker Hub images leaking secrets and 19 malicious VS Code extensions that used a PNG disguise to deliver trojans, underscoring persistent supply-chain and user-facing risks.

🚨The Korean National Police arrested four suspects accused of hacking over 120,000 IP cameras in homes and businesses and selling stolen intimate footage on an overseas illegal adult website. Authorities say the suspects uploaded large volumes of voyeuristic content, identified dozens of victims, and have already arrested some buyers. Police are working with foreign investigators to locate site operators, notify victims, and pursue takedown and remedial actions. Victims were urged to reset passwords, disable unneeded remote access, and apply firmware updates to prevent further compromise.

🔔 The FCC has warned that attackers have been hijacking US radio transmission equipment to broadcast false Emergency Alert System tones and obscene material, exploiting unsecured Barix network audio devices. Intruders reconfigured devices to pull attacker-controlled streams, causing stations in Texas and Virginia to air unauthorized Attention Signals layered with offensive language. The FCC urged broadcasters to apply vendor patches, change default credentials, isolate EAS and Barix devices behind firewalls or VPNs, monitor logs, and report incidents to manufacturers, the FCC Operations Center and IC3.

🔒 Singaporean researchers demonstrated how inexpensive offline dashcams can be weaponized into a self‑propagating surveillance network. They identified common weaknesses — default or hardcoded Wi‑Fi credentials, exposed services (FTP/RTSP), MAC‑spoofing and replay attacks — that allow attackers to download video, audio, timestamps and GPS metadata. The team showed mass compromise is feasible and offered mitigation steps for vendors and drivers.

⚠️ Fortinet’s FortiGuard Labs identified a Mirai-based botnet called ShadowV2 that exploited known vulnerabilities in routers and other IoT devices from D-Link, TP-Link, DD-WRT and others during a major AWS outage, appearing active only for the outage window and possibly a test run. The malware is delivered via a downloader (binary.sh) that fetches payloads from 81[.]88[.]18[.]108 and uses XOR-encoded configuration and Mirai-style strings. ShadowV2 supports UDP, TCP and HTTP DDoS floods and receives commands from a C2 at 198[.]199[.]72[.]27. Fortinet published IoCs and emphasizes keeping firmware updated, noting many affected models are end-of-life and will not be patched.

⚠️ FortiGuard Labs observed a Mirai-derived botnet named ShadowV2 actively exploiting multiple known IoT firmware vulnerabilities to deliver a downloader and ELF payloads that enable remote takeover and DDoS operations. The activity, detected during a late‑October global AWS connectivity disruption, targeted a wide range of devices including D-Link, TP‑Link, DD‑WRT variants and DVR systems. ShadowV2 decodes a XOR-encoded configuration (key 0x22), contacts a hardcoded C2 (silverpath.shadowstresser.info / 81.88.18.108), and supports UDP, TCP and HTTP flood methods. Fortinet provides AV detections, IPS signatures for the exploited CVEs, and recommends firmware updates, network hardening, and continuous monitoring.

⚠️ASUS has released firmware updates to remediate nine vulnerabilities, including a critical authentication bypass (CVE-2025-59366) affecting routers with AiCloud enabled.
