Critical Cisco Secure Email Gateway zero-day gives attackers root access

Actively exploited Cisco Secure Email Gateway zero-day CVE-2026-76461 lets crafted emails trigger SQL injection and root command execution; CISA added it to KEV.

Cisco released emergency patches for CVE-2026-76461, a critical SQL injection in Secure Email Gateway (physical and virtual) caused by insufficient validation in email parsing. Sending a crafted email with malicious SQL statements can yield arbitrary command execution with root privileges. Cisco was aware of active exploitation before the fixes, and CISA added the flaw to its KEV catalog; patched AsyncOS releases are 15.5.5-0141, 16.0.4-3021, and 16.5.0-780. Because successful exploits grant root, Cisco warns logs may be tampered with and advises checking external firewall/network logs and rebuilding virtual appliances with rotated credentials.

Exposed Vite servers are being probed for AWS and Azure credentials

F5 honeypots logged 32,000+ probes against Vite file-access bypass CVE-2026-39364, hunting AWS and Azure credentials on exposed dev servers.

F5 Labs reported 32,000+ scan attempts (807 attack sessions) against exposed Vite servers in August, up from 1,732 attempts over the prior three months. Attackers exploited CVE-2026-39364 (CVSS 8.2), which bypasses Vite's server.fs.deny protection via parameters like ?raw and ?import&raw, affecting Vite 7.1.0 to before 7.3.2 and Vite 8 before 8.0.5. Scanners cycled wordlists for environment files, AWS keys, Azure tokens and IaC state files, also combining older Vite CVEs (2025-30208, 2025-31125, 2024-45811) and probing a Next.js middleware bypass. Only CVE-2025-31125 is currently in CISA's KEV catalog.

Exaforce extends its AI security tool to monitor more than just Claude

Exaforce AI Security extends beyond Claude to monitor OpenAI, Gemini, and Copilot agents using existing SOC telemetry, no new endpoint agents.

Exaforce expanded its June Claude Compliance API integration into Exaforce AI Security, adding monitoring for OpenAI, Gemini, Microsoft Copilot, and OAuth-connected AI apps. The tool inventories AI agents by correlating EDR, cloud, SaaS, and model-provider logs without new gateways or endpoint agents, and can respond by revoking sessions, deactivating API keys, isolating devices, or killing agent processes via existing controls. Analysts note the agentless approach lowers friction but lacks runtime inspection and inline blocking offered by competitors such as Palo Alto Prisma AIRS, SentinelOne Prompt AI Agent Security, and CrowdStrike Falcon Guardian. A March 2026 Cloud Security Alliance survey found 68% of organizations cannot distinguish human from AI-agent activity and 74% report AI agents receive excessive access.

AI is exposing a security structure built for yesterday’s threats

EY's Jeffrey Sallet argues AI-driven deepfakes and impersonation require integrating cybersecurity, physical security, HR and legal functions.

The opinion piece contends AI-powered impersonation, deepfakes and automated social engineering cross digital, physical and operational boundaries that siloed security programs cannot cover. It cites an EY survey of 250 corporate leaders where only 12% feel most prepared to detect a targeted physical attack, and describes transnational groups using deepfakes and stolen identities to bypass virtual HR hiring loops. The author urges unified cross-functional verification pipelines and shared threat intelligence between CISOs and chief security officers.

What the 3M ChatGPT case reveals about AI governance

3M litigation shows ChatGPT prompts can become discoverable evidence, forcing enterprises to govern AI conversation records.

In the Watson Grinding explosion litigation, an engineering expert retained by 3M had used ChatGPT, and a surfaced prompt asked the system to 'show how 3M is 0% at fault'; after an off-record deposition demand, more than 350 pages of previously unproduced ChatGPT material were provided. The author argues AI interaction histories are becoming part of decision records and discovery material, a trend the American Bar Association has already examined. Enterprises are urged to manage retention, ownership, sharing, and deletion of AI conversation logs across tools like ChatGPT, Copilot, Claude, and Gemini.

India’s STPI serves TerminalFix-style attack via fake Cloudflare check

India's STPI government website serves a spoofed Cloudflare verification page that preloads malicious commands into visitors' clipboards for execution in Windows Terminal, matching TerminalFix-style attacks.

A malicious external JavaScript on the ananta.stpi[.]in subdomain of India's Software Technology Parks of India displays a fake Cloudflare 'Verify you are human' prompt and silently writes a URL into the visitor's clipboard, instructing the user to paste and execute it in Windows Terminal. Researcher Vibhum Dubey reported the behavior to STPI and CERT-In; the script loads from the recently registered cdn[.]quickdelivr[.]com and assigns each visitor a unique session identifier. The malicious script remained embedded after the overlay briefly disappeared, and the destination URL was flagged as malicious by 17 VirusTotal engines. No attribution has been established, though the pattern matches Microsoft's TerminalFix, a variant of ClickFix.

Google’s Early Access is creating a blind spot for malicious apps

Bitdefender found thousands of Google Play Early Access apps with deceptive behavior, including ad-fraud-capable utilities requesting excessive permissions on Android devices.

Bitdefender Labs analyzed Google Play apps installed by its users and identified thousands of Early Access applications that appeared deceptive, including fake casino and reward games, misleading utilities, and apps using third-party trademarks, many promoted via social ads with AI deepfakes. Early Access apps cannot receive public reviews, removing a key warning signal users normally rely on. Some apps requested unusual permissions, such as a QR scanner seeking to replace the device launcher, which could enable hidden web views that click ads and potentially display fake login screens or capture two-factor codes. Bitdefender recommends Android Enterprise Work Profiles and notes Google Workspace admins can disable Early Access apps for their organization.

Attackers are weaponizing the gap between Chromium fixes and Chrome patches

Espionage actors use the BlueMoon exploit kit to chain Chrome V8 and Windows kernel zero-days via spear phishing, gaining full admin on unpatched endpoints.

Proofpoint, working with Google Threat Intelligence Group, Microsoft Threat Intelligence Center and Volexity, reports that the BlueMoon exploit kit chains V8 type confusion CVE-2026-85046, V8 sandbox escape CVE-2026-87491 and Windows kernel LPE CVE-2026-85880, all rated high severity. The V8 flaws were fixed in upstream Chromium source but had not yet reached Chrome stable releases, creating a patch gap that attackers reverse-engineered and weaponized. A China-aligned state-sponsored actor used the kit from August 28 against a small number of US NGOs, mining and commodity trading firms via rapport-building spear phishing, and within days several mostly China-linked espionage clusters adopted BlueMoon. The chain yields full Windows admin privileges from a single phishing click; defenders should patch Chrome and Windows, apply Proofpoint detections and hunt for leftover artifacts.

AI workflows may be creating a dangerous new authorization blind spot

Noma Labs researchers describe 'workflow identity hijacking,' letting unauthenticated users trigger privileged AI workflows that execute actions with high-privilege service accounts.

Noma Labs lead researcher Sasi Levi detailed 'workflow identity hijacking,' where benign unauthenticated inputs via support inboxes, GitHub issues, or web forms trigger enterprise AI pipelines that execute privileged actions. The workflow runs using high-privilege service accounts or developer API keys, decoupled from the requester's identity, effectively creating a confused-deputy condition. Unlike prompt injection, the model behaves correctly; the failure lies in authorization enforcement at the workflow layer, and activity blends into routine automation. Mitigations include identity-aware access at execution points and user-context propagation between AI outputs and downstream operations.

Stealth rootkit targeting F5 BIG-IP could expose enterprise identity gateways

Sophos analyzed a stealth Linux rootkit that hides a web shell in memory on compromised F5 BIG-IP APM identity gateways, evading file-based detection.

Sophos analyzed a second-stage Linux rootkit implant found in compromised F5 BIG-IP APM environments running Apache and PHP, linked to exploitation of CVE-2025-53521, an unauthenticated RCE. The implant hooks Apache's PHP-loading process and serves modified in-memory versions of three legitimate webtop PHP files (apm_css.php3, full_wt.php3, webtop_popup_css.php3), leaving on-disk files untouched so hashes and integrity checks pass. It also establishes access via an authenticated local UNIX socket that can provide an interactive /bin/bash session. Experts warn compromised APM appliances, which handle federated SSO and terminate TLS at enterprise perimeters, could enable SSO token theft and lateral movement to trusted downstream applications.

When the prompt becomes the payload: A practical pen-testing guide for GenAI, LLM and RAG applications

CSO Online publishes a practical penetration-testing guide for GenAI, LLM, and RAG applications, covering prompt injection, retrieval poisoning, and tenant isolation testing.

The guide frames LLM applications as attack graphs spanning prompts, retrieval layers, vector stores, tools, identities, and downstream APIs, arguing that conventional web testing misses instruction-vs-data channel risks. It builds on OWASP prompt injection guidance (direct vs. indirect injection) and NIST's 2025 adversarial machine-learning taxonomy, noting that RAG and fine-tuning do not remove injection risk. Recommended practices include documenting trust transitions across components, using canaries and synthetic records to avoid test side effects, running multi-turn and obfuscated injection campaigns, and verifying chains from poisoned documents to observable state changes. It also details testing RAG pipelines via controlled document poisoning across metadata, OCR layers, and code comments, plus cross-tenant isolation checks on retrieved document IDs.

Experts from Strike Graph, Veracode, Delinea, and XBOW recommend treating agents as privileged insiders with hard technical boundaries: egress proxies with allowlists, short-lived brokered tokens, separated read/write rights, and approval for high-risk actions. XBOW describes a layered architecture with a guardian model reviewing agent actions and per-agent audit files. OWASP guidance on excessive agency urges limiting agent functions, permissions, and autonomy with authorization enforced downstream.

Sam Altman calls GPT-6 Astra rollout ‘messy’ as enterprise users wait for access

OpenAI's GPT-6 Astra launch hit access problems; Sam Altman apologized as availability gradually expanded from Daybreak partners to Pro, Enterprise, and API users.

GPT-6 Astra, launched September 4 as OpenAI's most advanced model, was initially accessible only to organizations enrolled in its Daybreak cybersecurity program, leaving Plus, Pro, Business, Enterprise, and API users waiting. Altman called the rollout 'messy'; by September 5 access had extended to Pro, Enterprise, and Business Premium users in ChatGPT's Work and Codex products plus the API. Analysts from Gartner and Greyhound Research said the staged rollout highlights the gap between announcement and production availability, urging enterprises to verify actual access levels and strengthen governance, security, and cost controls before adopting Astra's autonomous workflows.

Back-to-back N-able bugs send admins on a patching spree

CVE-2026-86218, a CVSS 10.0 pre-auth RCE in N-able N-central, is being exploited in the wild; Hotfix 4 mitigates it immediately.

N-able disclosed CVE-2026-86218 on September 6, a pre-authentication remote code execution flaw with CVSS 10.0 in its N-central RMM platform, and both N-able and Huntress report it is being exploited in the wild. It follows Huntress's disclosure of an exploit chain combining CVE-2026-86206 and CVE-2026-86207 that bypasses access controls to create unauthorized administrative accounts, investigated after a September 4 compromise of a fully patched customer environment. N-able has applied mitigations to all hosted N-central instances; on-premises customers must upgrade to Hotfix 4 (build 2026.3.1.14) immediately.
