AWS renews ProcessUnity Global Risk Exchange assessment

πŸ”’ AWS has renewed its ProcessUnity Global Risk Exchange assessment to help customers streamline third-party due diligence. The validated report, reviewed annually by ProcessUnity assessors, provides an updated view of AWS security posture for TPCRM integrations. The assessment replaces static spreadsheets with dynamic vendor profiles and risk analytics, and maps controls to standards such as NIST 800-53, ISO 27001, PCI DSS, and HIPAA. Customers can request access via the ProcessUnity portal.

Git fixes path-truncation flaw allowing code execution

πŸ”’ Git patched a critical vulnerability (CVE-2026-111760) that allowed malicious repositories with extremely long paths to bypass safety checks and write shortened names like .git, enabling attackers to replace submodule .git files with symlinks to malicious hooks or configuration. The fix, released in Git 2.56.1 and backported across 2.50–2.55 branches, rejects overly long paths before truncation. GitHub and other vendors are rolling out updates and advising users to install fixed versions and avoid recursively cloning untrusted repositories until patched.

Why ZTNA Outperforms VPN for Remote Access

πŸ” The traditional VPN-and-firewall perimeter model is increasingly inadequate and risky as remote work and cloud services expand. ZTNA replaces broad network access with fine-grained, context-aware application access, assessing user identity, device posture, and location. This reduces blast radius from compromised credentials and limits lateral movement, while enabling just-in-time access and richer logging for SOC teams. ZTNA complements, not replaces, endpoint protection and may coexist with legacy VPN where needed.

SGLang RCE Breach Compromises NEAR AI Systems

πŸ”’ An RCE bug in SGLang, the open-source inference engine, was exploited to run code on a NEAR AI inference server, potentially exposing requests processed that day, including those in confidential mode. The attacker moved laterally to a deprecated Private Chat system and an older NEAR AI Agents deployment, exfiltrating about 100 user account details and data from 18 agents. NEAR AI revoked credentials, deployed a fix, rotated tokens, and completed forensics, and has notified impacted users.

Critical Xen Orchestra Authentication Bypass Exploited

πŸ”’ French vendor Vates VMS warned of a critical authentication bypass in Xen Orchestra, tracked as VSA-2026-062, that is being actively exploited. The flaw allows specially crafted cookies to be parsed into an empty object which the token provider treats as an unfiltered lookup, returning a valid token and enabling Admin-level actions. Exploitation can lead to arbitrary code execution on managed pools and full XCP-ng node takeover as root. Patches are available in Xen Orchestra 6.9.1/6.10.0 and xo-server 5.211.2/5.213.1; mitigations include blocking the malicious IP/TOR, avoiding internet exposure, and rotating credentials.

Integrating CodeMender Automated Fixes into PRs

πŸ”§ This post introduces CodeMender, Google’s autonomous code-security agent that integrates automated vulnerability detection, verification, and patching directly into Git pull requests using Google Cloud Run. The article outlines how CodeMender posts findings in PR timelines, supports /verify and /fix commands, and streams sandbox artifacts to Cloud Storage for audits. It emphasizes secure execution by running exploit simulations as ephemeral Cloud Run jobs with minimal service account privileges and network egress restrictions, and recommends using short-lived OIDC tokens for GitHub trust.

CISA Revises Incident Report Form to Include ATT&CK

πŸ›‘οΈ CISA has launched a revised cyber incident reporting form accessible via its Incident Reporting Portal, introducing more granular questions about malware, social engineering, hacking and insider threats and mapping observed activity to MITRE ATT&CK. The update, announced on November 9, is designed to improve data quality, enable linking of related threat activity into broader trends, and support faster, more thorough threat analysis. Federal civilian agencies remain required to report, while others can submit voluntary reports potentially protected under the PCII Program.

Inside the Gemini Factory: Partner Acceleration

πŸ› οΈ The Gemini Factory is a Google Cloud co-innovation program that helps enterprise software partners turn use cases into production integrations rapidly. It unifies extensibility primitivesβ€”MCP connectors, declarative Skills, Plugins, and A2A agentsβ€”so partners can embed domain intelligence and regulated workflows directly into Gemini. Through hands-on workshops, AI-assisted development tools like Antigravity and RAD, and commercial incentives including seed credits and marketplace listing, partners can build, publish, and scale solutions with reduced engineering friction and streamlined deployment.

BigQuery Measures Unify BI Metrics and Knowledge Graphs

🧭 BigQuery introduces measures, now GA, to unify governed BI metrics with knowledge graph relationships so AI agents and dashboards see both the "what" and the "why". By defining measures directly on graph entities, BigQuery preserves entity grain, avoids overcounting, and enables traversal-based explanations without separate systems. The GA adds composite and derived measure support, semantic metadata, Knowledge Catalog integration, and visualizations in Data Studio for consistent, discoverable metrics.

France Blames Iranian Hackers for Freezer Sabotage

🧊 French authorities accuse an IRGC-linked hacking unit of seizing control of refrigeration systems at about 700 retail and food sites on 11 October, altering defrost settings and triggering at least 15 fires and tens of millions of euros in damage. Victims included major supermarket chains and food processors, with targeted controllers reportedly running older Danfoss software. Investigators linked the operation to the Shahid Kaveh group through shared infrastructure, Farsi traces, and subsequent propaganda claims, and named three alleged IRGC operatives. Officials warn organisations to secure OT systems by removing internet exposure, updating controller software, changing default passwords, and segmenting and monitoring networks.

Blind Eagle reuses court-themed lures to deliver RAT

πŸ›‘οΈ The Blind Eagle group (APT-C-36) has launched a campaign using Portuguese and Spanish judicial and administrative-themed phishing lures to deliver a remote access trojan related to AsyncRAT and DCRat. Emails target personnel handling legal, contract, or institutional requests and use weaponized XHTML/SVG files that employ HTML smuggling to assemble ZIP payloads in the browser. The JavaScript dropper pretends to be a network auditor and performs environment reconnaissance before running a VBScript that bypasses AMSI/ETW, removes artifacts, and persists via the Windows Startup folder, ultimately launching the final RAT in memory via PowerShell.
