Zoom for Windows security update blocks DLL hijacking and privilege escalation (CVE-2025-49457)

Zoom for Enterprise: close DLL path attacks, move to 6.3.10 today

Zoom delivered security fixes for Windows clients after investigators identified CVE-2025-49457, an untrusted DLL search path that can enable local privilege escalation and broader compromise. Because attackers chain DLL hijacking with lateral movement, admins should update Windows endpoints to version 6.3.10 and validate explicit path loading. This analysis explains affected apps, exploitation flow, high-signal detection, and quick remediation steps so defenders can reduce risk without adding noise.

ClickFix phishing page coaching a user to paste a command that steals M365 access

ClickFix Lures Coach Users to Self-Infect and Bypass Filters

ClickFix campaigns scale by coaching users to “fix” access issues with copy-paste commands. After the click, actors steal Microsoft 365 tokens or credentials and, in some cases, drop PureRAT for persistence. Break the flow by enforcing admin-only app consent, requiring phishing-resistant MFA, and blocking browser-to-shell chains. Investigate mailbox rules, token reuse, and OAuth grants whenever ClickFix pages appear in referral logs.

BGP upstream map highlighting AS30823 (aurologic) feeding multiple high-risk hosting ASNs across Europe

Sanctions vs. Transit: Aeza’s Reliance on aurologic Connectivity

aurologic GmbH (AS30823) operates a multi-terabit backbone out of Langen and connects multiple high-risk hosting providers including sanction-linked entities—giving malware C2 and staging servers durable reach. This analysis explains why upstream neutrality often translates into enablement, how TAEs cluster under aurologic, and what blue teams can do: upstream-aware detections, deny-by-default on risky cones, flowspec/RTBH during incidents, and procurement levers that force faster de-peering.

Legacy CVEs and misconfigured IIS enable stealth access via msbuild and DCSync

China-Aligned Abuse msbuild, DCSync After Legacy CVE Break-ins

A China-linked crew still breaks in through legacy CVEs Log4j, Struts, Confluence, GoAhead then hides behind scheduled tasks and msbuild.exe to run memory-resident payloads. They probe domain controllers with DCSync, and they target misconfigured IIS by abusing ASP.NET machine keys to deploy TOLLBOOTH with SEO cloaking. Reduce risk by patching edge services, restricting LOLBAS on servers, rotating machine keys, and alerting on replication from non-DC hosts.
