🔔 LastPass is warning users about an active phishing campaign observed from around January 19, 2026, that impersonates the service and urges users to create local backups within 24 hours to harvest master passwords. The messages route recipients through a staged AWS S3 URL that then redirects to a fraudulent domain (mail-lastpass[.]com) and originate from several spoofed support addresses. LastPass said it will never ask for master passwords and is working with partners to take down the malicious infrastructure while urging users to report suspicious messages.

🔒 Cloudflare patched a logic flaw in its ACME HTTP-01 handling that could disable certain WAF protections for specific challenge paths. The issue was reported by researchers from FearsOff through Cloudflare’s bug bounty program on October 13, 2025, and affected requests to /.well-known/acme-challenge/*. In some cases, challenge requests could reach customer origins when they should have been blocked because WAF features were incorrectly disabled. Cloudflare implemented a code change to ensure WAF disabling only occurs when Cloudflare will serve a valid ACME challenge response; no customer action is required and there is no known abuse.

⚠️ Researchers disclosed that a critical Fortinet FortiSIEM vulnerability (CVE-2025-64155) with public proof-of-concept code is being abused in active attacks. Horizon3.ai described the issue as an unauthenticated OS command injection via exposed phMonitor command handlers that enables arbitrary writes and escalation to root, and Fortinet released security updates plus a port-restriction workaround for phMonitor (7900). Administrators should upgrade affected FortiSIEM versions 6.7 through 7.5 to the patched releases and review phMonitor logs for indicators of compromise.

🔒 Cisco has released a fix for a maximum‑severity AsyncOS zero‑day (CVE-2025-20393) that has been exploited since November 2025. The flaw impacts Cisco Secure Email Gateway and Secure Email and Web Manager appliances with non-standard configurations when the Spam Quarantine feature is exposed to the internet, permitting arbitrary command execution as root. Cisco Talos links the intrusions to a Chinese-nexus actor tracked as UAT-9686, which deployed persistence and tunneling implants and a log-wiping utility. CISA has added the vulnerability to its known exploited vulnerabilities catalog and ordered federal remediation under BOD 22-01.

⚠️ Check Point Research links the Linux-based RondoDox botnet to a coordinated exploitation campaign against HPE OneView, leveraging the critical RCE flaw CVE-2025-37164.

Check Point reported blocking more than 40,000 hits on 7 January 2026 and urged organizations to patch immediately and implement compensating controls.

⚠️ Microsoft has confirmed that the January 13, 2026 cumulative update (KB5073455) can prevent some Windows 11, version 23H2 devices with System Guard Secure Launch enabled from shutting down or entering hibernation, causing them to restart instead. The issue is limited to Enterprise and IoT editions where the update is offered. Microsoft recommends the temporary workaround shutdown /s /t 0 for shutdowns and warns there is currently no hibernation workaround. Users should save work and perform manual shutdowns to avoid battery drain.

🔒 Cisco has released patches for a maximum-severity remote command execution vulnerability (CVE-2025-20393, CVSS 10.0) in AsyncOS that affects Cisco Secure Email Gateway and Secure Email and Web Manager. The defect stems from insufficient validation of HTTP requests in the Spam Quarantine feature and can allow arbitrary commands to run as root when the feature is enabled and reachable from the internet. Cisco says a China-nexus APT tracked as UAT-9686 exploited the bug in the wild, deploying tunneling tools, a log-cleaner and a Python backdoor, and that fixes remove persistence artifacts. Administrators should apply the provided fixed releases and follow the vendor's hardening guidance to restrict access and monitor for anomalous activity.

🔐 Researchers at Varonis Threat Labs uncovered 'Reprompt', a one-click attack that abuses Microsoft Copilot Personal by embedding prompts in URLs and using follow-up server requests to exfiltrate data. It combines a URL 'q' parameter injection, a double-request bypass of initial sanitization, and chained server instructions to siphon conversation history and files without further user interaction. Microsoft issued a patch; organizations should treat prefilled prompts as untrusted and enforce continuous authentication, least privilege, prompt hygiene, auditing, and anomaly detection.

🔒 Palo Alto Networks has released patches for PAN-OS after a researcher disclosed CVE-2026-0227, a high-severity (CVSS 7.7) vulnerability in GlobalProtect gateway and portal components that can trigger a denial-of-service and force affected firewalls into maintenance mode. The vendor reports no known in-the-wild exploitation but acknowledges proof-of-concept code exists. Prisma Access customers have largely been upgraded; on-premises NGFWs must apply vendor updates per the posted remediation table. There are no official workarounds; temporarily disabling the VPN interface may reduce risk while patching.

🔒 Hackers are actively exploiting a maximum-severity authentication bypass in the Modular DS WordPress plugin (CVE-2026-23550) to gain admin-level access on vulnerable installs. The flaw affects versions 2.5.1 and earlier and was first observed in the wild on January 13; the vendor released a fix in version 2.5.2 shortly after disclosure. Site owners should update immediately, review server logs, verify admin accounts, and regenerate WordPress salts after patching.

🔐 The US Cybersecurity and Infrastructure Security Agency (CISA), the UK’s National Cyber Security Centre (NCSC) and the Federal Bureau of Investigation (FBI), alongside international partners, have released principles to secure operational technology (OT) connectivity. Led by NCSC-UK, the guidance offers a shared framework to design and manage secure connectivity across OT environments. It emphasizes embedding cybersecurity into network design to reduce exposure to both state-backed and opportunistic adversaries. The document warns that increased interconnection brings benefits such as real-time analytics and predictive maintenance, but also raises risks that could cause physical harm, environmental damage or service disruption.
