🔒 Security researchers have uncovered Operation WrtHug, a global campaign that has hijacked thousands of largely end-of-life ASUS WRT routers by chaining at least six known vulnerabilities. Over roughly six months analysts identified about 50,000 unique infected IPs, predominantly in Taiwan, using a distinctive malicious self-signed AiCloud certificate with a 100-year lifetime as an indicator of compromise. Owners are urged to apply ASUS firmware updates or replace unsupported models and disable remote-access features to mitigate risk.

🔐 Eurofiber Group said its French subsidiary, Eurofiber France, experienced a breach after attackers exploited a software vulnerability to access its ticket management system and exfiltrate data. The company stated that sensitive bank details and other critical data were not affected. The incident impacted the ATE cloud portal and regional sub-brands (Eurafibre, FullSave, Netiwan, Avelia). Eurofiber says it closed the vulnerability, strengthened controls and engaged cybersecurity experts to support customers.

⚠️CISA has added CVE-2025-13223, a Google Chromium V8 type confusion vulnerability, to its Known Exploited Vulnerabilities (KEV) Catalog following evidence of active exploitation. This class of flaw is a frequent attack vector and poses significant risk to the federal enterprise and other organizations using Chromium-based engines. Under BOD 22-01, Federal Civilian Executive Branch agencies must remediate KEV entries by the required due date; CISA strongly urges all organizations to prioritize timely patching and vulnerability management to reduce exposure.

🔒 SecurityScorecard's STRIKE team warns that Operation “WrtHug” has already compromised thousands of ASUS WRT routers worldwide by chaining six primarily legacy vulnerabilities to gain elevated privileges and persistence. The campaign abuses the ASUS AiCloud service and OS injection flaws, deploying a common self-signed TLS certificate with a 100-year expiry. SecurityScorecard notes geographic clustering, with up to 50% of victims in Taiwan, and assesses a likely China-affiliated ORB-style operation.

⚠️ RondoDox operators are exploiting a critical remote code execution flaw in XWiki Platform (CVE-2025-24893), which CISA flagged as actively exploited on October 30. VulnCheck observed attacks beginning November 3 that inject base64-encoded Groovy into the XWiki SolrSearch endpoint via a crafted HTTP GET to download and run a remote shell (rondo..sh) that stages the main payload. Administrators should upgrade to 15.10.11 or 16.4.1, apply network controls, and use published IoCs to block scanning and payload hosts.

🔒 This week's recap highlights a surge in quiet, high-impact attacks that abused trusted software and platform features to evade detection. Researchers observed active exploitation of Fortinet FortiWeb (CVE-2025-64446) to create administrative accounts, prompting CISA to add it to the KEV list. Law enforcement disrupted major malware infrastructure while supply-chain and AI-assisted campaigns targeted package registries and cloud services. The guidance is clear: scan aggressively, patch rapidly, and assume features can be repurposed as attack vectors.

🔒 Microsoft released updates addressing more than 60 vulnerabilities across Windows and related products, including a zero-day memory-corruption bug (CVE-2025-62215) that is already being exploited.
