The extension you never installed: KREMLIN forges Chrome's own integrity checks to steal banking sessions
Elastic details KREMLIN, a Brazilian banking malware whose malicious Chrome/Edge extension forges Chromium integrity checks to steal sessions.
Elastic Security Labs tracked operation REF9334 and its KREMLIN toolkit, a Brazilian banking malware campaign impersonating twelve banks across seven campaigns since May 2025. The infection chain uses multi-stage obfuscated JavaScript loaders with sandbox checks (file and process counting), scheduled-task persistence, and an Ethereum smart contract acting as a dead-drop resolver for C2 and payload URLs, abusing Archive.org for hosting. The malicious browser extension bypasses Chromium integrity mechanisms by manipulating Secure Preferences and regenerating required HMACs and App-Bound encrypted hashes. Threat Command disrupted over 1,500 infections by registering the kill-switch canary domain.

Session Attestation for Unmodified TLS Services in Confidential Virtual Machines
SessionLatch adds session attestation to unmodified TLS services in confidential VMs, cutting short-upload latency 63.1% versus TNG on Hygon CSV.
SessionLatch provides session attestation for confidential virtual machines without modifying applications, TLS implementations, or certificates. It relies on trusted observation of the server's locally generated ephemeral public key combined with standard TLS key confirmation, moving attestation integration to the operating system via a temporary latch that overlaps evidence exchange with the TLS handshake. Implemented with Linux and Windows integrations and evaluated on real Hygon CSV attestation, it reduces short-upload mean latency by 63.1%/23.0% relative to TNG in interleaved Linux/Windows experiments, while preserving enterprise service authentication and the native TLS data path, and supports mutual attestation.

Remote Desktop Services Failures on Windows Servers Following September Update
September 2026 Patch Tuesday updates cause Windows Server 2019/2022/2025 RDS sessions to freeze, forcing administrators to roll back.
Cumulative updates KB5122876 (Windows Server 2019), KB5122882 (2022), and KB5122871 (2025) trigger Remote Desktop Services freezes hours after boot, with RDP connections hanging at 'Connecting…' and Event ID 20498 logged. Administrators trace the fault to an apparent deadlock in RDPSERVERBASE!WDLIB_Close during session teardown; only hard resets restore service and the issue recurs. The same September release patched roughly 973 vulnerabilities, including two actively exploited zero-days (CVE-2026-81963, CVE-2026-85880, both in CISA's KEV) and a critical RDS RCE, CVE-2026-69525 (CVSS 9.8). Workarounds include DISM-based removal of the update or an unofficial FeatureManagement registry key disabling the suspected audio-redirection code path; Microsoft has not yet confirmed the bug.

FortiPAM Chrome Extension Vulnerability Lets Malicious Sites Control Browser Proxy and Record Tabs
Fortinet patched CVE-2026-84388 (CVSS 9.1) in its FortiPAM Chrome extension, letting malicious websites alter proxy settings, open tabs and record sessions.
The Fortinet FortiPAM Chrome extension flaw (CVE-2026-84388, CVSS 9.1) lets attacker-controlled domains be trusted as FortiPAM servers because a webRequest listener adds requested hostnames without verifying the initiator. A second issue exposes the extension's message interface to all URLs and accepts non-JWT tokens without validation, enabling unauthenticated session launches, proxy manipulation, tab control and recording; the consent dialog can also be bypassed via shadow-root clicks. Fortinet issued advisory FG-IR-26-168 after a July 17 report and released a fix on August 1, 2026, with no confirmed exploitation in the wild.

OpenAI's Artifactory opened covert data-stealing channel alongside Hugging Face attack
Check Point disclosed a covert cross-account channel in OpenAI's internal JFrog Artifactory that let one ChatGPT session exfiltrate another user's connected-app data.
Check Point Research found that OpenAI's internal JFrog Artifactory instance exposed an item management feature allowing one ChatGPT container to attach hidden, Base64-encoded tasks that another user's session would execute with the victim's privileges, such as pulling Gmail emails and exfiltrating them invisibly. Reader credentials granted both read and write access, enabling cross-account task injection. The flaw was reported in late June, and OpenAI had already decommissioned the Artifactory instance following the related Hugging Face intrusion, closing the channel.

CVE-2026-86206, CVE-2026-86207: N-able N-central Authentication Bypass (FIXED)
Rapid7 disclosed two chained N-able N-central flaws, CVE-2026-86206 and CVE-2026-86207, enabling unauthenticated admin account creation; patched in 2026.3 Hotfix 3.
Rapid7 researchers found CVE-2026-86206 (semicolon/Forwarded access-control bypass, CWE-791, CVSSv4 6.9) and CVE-2026-86207 (UserTwoFactorLogin authentication bypass, CWE-305, CVSSv4 7.7) in the latest N-able N-central. Chained, they let a remote unauthenticated attacker create an attacker-controlled System administrator account. The bugs stem from Envoy and Jetty disagreeing on the requested path and whether the client is local. N-able patched both in N-central 2026.3 Hotfix 3, following the earlier CVE-2026-18577 authentication bypass.

NASA AIT-GUI Flaws Could Let Unauthenticated Attackers Issue Spacecraft Commands
Researchers disclosed 9.4-CVSS flaws in NASA/JPL's AIT-GUI allowing unauthenticated attackers to issue arbitrary spacecraft commands via exposed command endpoints.
Cycode disclosed a flaw chain in AIT-GUI, the browser-based operator console for NASA/JPL's open-source AMMOS Instrument Toolkit, tracked as GHSA-p9r8-2q67-fp86 with CVSS 9.4, affecting versions 2.5.1 and earlier. The server binds to 0.0.0.0:8080, issues sessions without credential checks, and lets unauthenticated users issue spacecraft commands via POST /cmd and reach files outside intended directories via /script/run and /seq (CWE-306, CWE-352, CWE-22). Version 2.5.2 adds host binding and same-origin checks but does not add authentication, and a related missing-authentication flaw was published separately as CVE-2026-60112 with CVSS 9.3.
