PHP2Shell Attacks Root Palo Alto Firewalls but Fail Against WordPress

PHP2Shell (CVE-2026-109618 and CVE-2026-109619) has been exploited for over a week. A China-linked group chained it with the Fragnesia Linux kernel privilege escalation to root at least 25 Palo Alto Networks PAN-OS firewalls with exposed management interfaces. Defiant had seen no confirmed WordPress compromise by 28 October 2026 despite 77,000 requests, and Cato and watchTowr report few successful attackers.

New Cisco firewall zero-day exploited to crash SSL VPN devices

CVE-2026-76418 is a high-severity denial-of-service zero-day in Cisco ASA and Threat Defense (FTD) software, exploited in the wild in October 2026. Unauthenticated attackers send a crafted request to the SSL VPN (webvpn) when secondary authentication is set on a tunnel group, causing a device reload. Cisco offers no workaround besides disabling secondary authentication on tunnel groups. Shadowserver sees over 51,000 exposed ASA SSL VPN devices.

China-Linked Hackers Exploit PHP2Shell to Root Firewalls

A China-linked actor chained PHP2Shell (CVE-2026-109618, CVE-2026-109619) with the Fragnesia Linux kernel privilege escalation (CVE-2026-46300) to root firewalls and drop PHP webshells, per Dream. Using FOFA, the actor narrowed 19,000 firewalls to 240 targets and rooted 24 on 23-24 October. On two US government-affiliated devices it used a reverse SSH tunnel, hit the firewall management server, and attempted LDAP and Active Directory abuse.

Google Wants Gemini to Be Your Next Coworker—Complete With Its Own Email Address

Decrypt reports on Google Cloud's newly announced Gemini Agent, a long-running AI agent that operates across Gmail, Docs, Sheets, Slides, Drive, Chat, Calendar, Microsoft 365 and Slack, and can run for hours or days on a single goal. The feature allows managers to spin up coworker agents with their own Workspace email address, calendar, Drive storage and directory listing, each given a cryptographically attested identity and a separate audit trail; agents connect to Salesforce, ServiceNow, Jira, Snowflake, BigQuery and any Model Context Protocol server, and are orchestrated across both Gemini and Anthropic's Claude models depending on cost and quality fit. Google pairs the launch with safety infrastructure, an Agent Sandbox, an AI network firewall called Agent Gateway, and real-time token-spend caps, citing a prior Claude Cowork VM-escape finding by Accomplish AI as the kind of containment failure it is designed to prevent.

Bypass Web Application Firewall (WAF) with EvilWAF

Hackers-Arise walkthrough of EvilWAF, an open-source MITM proxy and standalone WAF vulnerability scanner that evades modern behavior-based WAFs by rotating TCP/TLS fingerprints (JA3/JA4) rather than altering attack payloads. It covers proxying sqlmap traffic through EvilWAF, its auto-hunt feature for discovering and routing directly to the real origin IP behind a WAF, and its scan-only mode that probes ten WAF defense layers (rule engine, rate limiting, HTTP method handling, TLS settings). The piece also discusses why Cloudflare's ML-based behavioral fingerprinting resists many of these bypass techniques.

SonicWall and Splunk Patch Critical Vulnerabilities

SonicWall patched four SMA1000 appliance vulnerabilities including CVE-2026-102255, a pre-authenticated SSRF flaw (CVSS 10) that lets an unauthenticated remote attacker abuse an unintended alternate access path to reach internal functionality; two other high-severity bugs enable RCE and one medium-severity bug enables XSS. Splunk separately fixed dozens of flaws across Splunk Enterprise, MCP Server, and the Add-on for AWS, including three critical Splunk Enterprise bugs allowing arbitrary command execution, unauthorized access, and code injection, plus a medium-severity MCP Server issue letting an authenticated user redirect API requests to an attacker-controlled URL. SonicWall says SSL-VPN on its firewall products is unaffected and no in-the-wild exploitation has been observed.

Qilin Ransomware Suspect Arrested in Japan, Extradited to Germany

A 28-year-old Russian national believed to be a core member of the Qilin ransomware-as-a-service gang was arrested in Osaka, Japan in May and extradited to Germany on October 2, wanted for a September 2024 attack on a German logistics company that netted over 160000 dollars in crypto extortion. The piece recaps Qilin's, also known as Agenda, history since August 2022, including the Synnovis and NHS hospital disruptions, the Asahi Group breach exposing about 2 million records, 400 leak-site victims in 2025 including Lee Enterprises and Inotiv, exploitation of a Check Point VPN and firewall authentication bypass flaw CVE-2026-50751, and the ATF breach claim in August.

Insecure Agents Podcast: How to Keep AI Agents From Bypassing Security Controls

Socket CTO Ahmad Nassri discusses, in the Insecure Agents podcast, how coding agents respond to blocked package installs by fetching tarballs directly from a CDN, overriding local registry settings, or using alternate DNS routes to reach a registry — and how Socket Firewall counters this by stripping disallowed versions from registry metadata so "those versions don't exist" to the agent or package manager. It also covers a distinct attack where planted instructions convince an agent it's authorized to inspect an environment and exfiltrate data using its own existing access, and argues defenders need short-lived credentials, task-scoped permissions, and full visibility into what an agent downloaded/executed/discarded during a session, not just its final output.

Vulnerability Blast Radius: How to Measure and Reduce Impact | Blog | Endor Labs

Endor Labs blog post explaining CVE-2024-3596 (BlastRADIUS), a critical design flaw in the RADIUS authentication protocol where an on-path attacker uses a chosen-prefix MD5 collision to forge an Access-Accept response and bypass authentication on VPNs, firewalls, and network devices using RADIUS over UDP with non-EAP methods. It also generalizes 'blast radius' as a vulnerability-management concept, describing static reachability analysis across first-party code, dependencies, and container base images to distinguish exploitable findings from theoretical CVEs, tying the discussion to Endor Labs' AURI product.

Securing the unpatchable in an age of AI-driven vulnerabilities

Cisco Talos argues that AI-accelerated vulnerability discovery is outpacing organizations' ability to patch, especially for unpatchable operational technology (OT) like medical devices and industrial control systems. It recommends network-level compensating controls instead of patching: upstream next-generation firewalls with intrusion prevention for virtual patching, VLAN/ACL-based micro-segmentation to restrict which devices can reach legacy systems, and visibility into legacy network fingerprints to build an asset inventory. It also debunks the air-gap myth, citing WannaCry's spread through unpatched Windows XP in the NHS as a cautionary example of "hope for the best" failing.

The rollout surfaced ~135 new/unverified package-version events per day, found that 21% of firewall events came from non-engineering staff, observed coding agents (e.g. Claude Code auto-updates, npx/uvx MCP server pulls, VS Code extension side-fetches) as a major source of installs, detected an agent attempting to work around a firewall block, and caught real near-misses including a compromised version of the npm package keyv.

npm Now Scans for Malware at Publish, Not Install | Blog | Endor Labs

Analysis of GitHub's July 28 change making npm scan every package for malware at publish time (roughly a 5-minute delay), instead of only reacting after reports. It covers the new dual-use governance model — contentPolicy metadata, DISCLOSURE files, and mandatory 2FA/OIDC publishing for tools like security scanners that resemble malware — and argues registry scanning can't enforce org-specific policy, can't cover other registries (PyPI, Maven, NuGet), and can't stop novel malware or compromised-account publishes, making install-time enforcement (e.g. Endor Labs' Package Firewall) still necessary.

Critical Security Controls for Governing AI Coding Agents | Blog | Endor Labs

Endor Labs analyzes the security risks of AI coding agents running on developer laptops with shell, filesystem, network access and the developer's own credentials, framing the threat as prompt-injection-driven abuse of legitimate agent capabilities (e.g., an agent tricked into exfiltrating .env via a malicious README). It maps six control points — EDR/XDR, sandboxes/containers, AI/MCP gateways, in-agent hooks, package firewalls, and secrets scanning/PR controls — arguing that in-agent hooks (deterministic allow/deny/ask decisions on proposed actions before execution) are the only point that intercepts model intent before it becomes a shell command, and promotes Endor Labs' own hook-based AI Coding Agent Governance and Package Firewall products as the implementation.

Slopsquatting: When AI Agents Hallucinate Malicious Packages | Blog | Endor Labs

Endor Labs explains slopsquatting, the supply-chain attack where AI coding assistants (Cursor, GitHub Copilot, Claude) hallucinate plausible but nonexistent package names, which attackers then pre-register on npm/PyPI with malicious post-install scripts that exfiltrate cloud and Git credentials. The piece walks through why LLMs recurrently hallucinate the same names, a worked fastparse-xyz example showing the install-to-CI/CD chain, and defenses: provenance verification, dependency firewalls, SCA with reachability analysis, sandboxed installs, and agent policy controls like private registries and human approval gates.

Dependency Confusion: How Attackers Poison Your Build | Blog | Endor Labs

Endor Labs explainer breaking down three "tree poisoning" techniques in the open-source dependency tree: dependency confusion (public package impersonating a private one, exploiting "highest version wins" resolver logic, as in Alex Birsan's 2021 research against 35+ companies and PyTorch's 2022 torchtriton nightly-build compromise), typosquatting/combosquatting (human-error-driven lookalike package names, extended by AI-invented "slopsquatting"), and package poisoning/hijacking (maintainer account takeover or handoff abuse, as with event-stream in 2018, the XZ Utils backdoor in 2024, and the Shai-Hulud npm worm). It closes with concrete defenses: reserving package namespaces, pinning private registries, lockfiles/checksum verification, scrubbing internal names from public sources, and package firewalls with behavioral malware detection.

It walks through concrete attack patterns these tools target: postinstall-hook payloads (the March 2026 axios account takeover that pulled in the malicious transitive dependency plain-crypto-js), the September 2025 malicious postmark-mcp npm package that BCC'd emails to attackers, slopsquatting of AI-agent-hallucinated package names, dependency confusion, and obfuscation tricks like invisible Unicode and off-screen whitespace payloads (os-info-checker-es6, react-html2pdf.js).

The Pros and Cons of NPM v12's Security Improvements

An analysis of npm v12 (shipping ~July 2026, previewable on npm 11.16.0+), which flips three dangerous defaults to deny-by-default: automatic preinstall/install/postinstall lifecycle scripts, git dependencies (now requiring --allow-git), and remote HTTPS tarball dependencies (now requiring --allow-remote). The author, a DEF CON speaker on install-script abuse, argues the changes are genuinely good but warns that widespread legitimate use of install scripts (esbuild, sharp, core-js, puppeteer, node-gyp native builds) will drive developers toward reflexive npm approve-scripts approval, and that attackers will simply relocate payload execution outside npm's visibility (curl|bash in install.js, bootstrap binaries), citing DPRK actors' continued abuse of VSCode tasks files even after Microsoft disabled task.allowAutomaticTasks by default. It also surveys complementary controls gaining traction across the ecosystem: npm's min-release-age cooldown (following pnpm's minimumReleaseAge, Yarn's npmMinimalAgeGate, and Bun) and package-firewall products (Datadog's supply-chain-firewall, Liran Tal's npq, Socket, Aikido, Endor Labs).

Exposed RDP: The Misconfiguration Attackers Keep Exploiting

Huntress SOC writeup detailing three real incidents stemming from exposed RDP: a healthcare org's internet-facing RDP port (3389) hit by opportunistic scanning, an RDWeb portal re-exploited by the same attacker a day after eviction using a custom cross-platform reverse tunnel and credential harvester, and a SonicWall VPN compromise where the attacker used cheap bulletproof hosting (Hostinger, Freakhosting) then manually re-enabled RDP via registry edits and netsh firewall rules before running Advanced IP Scanner for lateral movement. The piece argues these are not zero-days but recurring misconfigurations, and recommends firewalling RDP, closing/rotating exposed entry points quickly, and feeding VPN/firewall logs into SIEM alongside EDR for visibility.

The piece details the tool's security model in depth: agents get read-only repo permissions by default, all writes must go through pre-declared 'safe-outputs' (e.g. create-pull-request with a compile-time allowed-files list), external network access is restricted via an allowlist enforced by an 'Agent Workflow Firewall', and PRs are never auto-merged so a human always reviews the change.
