Chinese APT Abuses ArcGIS Component to Maintain Backdoor

🔐 ReliaQuest linked the campaign to the Flax Typhoon APT, which converted a legitimate public-facing ArcGIS Java server object extension (SOE) into a stealthy web shell. The group activated the SOE through a standard ArcGIS REST extension, embedding a base64-encoded payload and a hardcoded key to trigger command execution while hiding activity behind normal portal operations. Attackers uploaded a renamed SoftEther VPN binary to preserve access and targeted IT workstations, and the SOE was later found in backups, enabling persistence after remediation. ReliaQuest warns organisations to go beyond IOC detection, proactively hunt for anomalous behaviour in trusted tools, and treat every public-facing application as a high-risk asset.

October 2025 Patch Tuesday: 172 CVEs, 3 Zero-Days, 8 Critical

New zero-day in Gladinet re-enables patched RCE flaw

⚠️ Huntress has observed criminals exploiting a new zero-day (CVE-2025-11371) in Gladinet CentreStack and Triofox file-sharing servers that enables unauthenticated local file inclusion. The flaw can expose the application's Web.config machineKey, effectively re-enabling a prior ViewState deserialization RCE (CVE-2025-30406). Gladinet has not yet released a patch; Huntress advises disabling the UploadDownloadProxy temp handler as a mitigation. Huntress detected misuse across multiple customers and notes that SOC telemetry flagged irregular base64 payloads; administrators should assume 'fully patched' may not equal secure and isolate or disable vulnerable handlers until a vendor patch is available.

Microsoft Restricts Edge IE Mode After Active Exploits

🔒 Microsoft has tightened access to Internet Explorer mode in Edge after credible reports in August 2025 that unknown actors abused the legacy compatibility feature to compromise devices. Attackers used social engineering to coerce users into reloading pages in IE mode and then chained unpatched Chakra JavaScript engine exploits to gain remote code execution and elevate privileges. Microsoft removed the IE mode toolbar button, context-menu and hamburger-menu entries; IE mode must now be enabled explicitly via Edge settings and sites must be added to an IE mode pages list.
