Malcious Admin Menu Editor Pro plugin backdoors 1,500 WordPress sites

Compromised Admin Menu Editor Pro update server distributed backdoored plugin versions installing web shells and hidden admin accounts on roughly 1,500 WordPress sites.

A threat actor with root-level access to adminmenueditor.com pushed trojanized Admin Menu Editor Pro versions 2.35 and 2.36 containing includes/wp-user-consent.php, which installed a web shell and created a hidden wp_-prefixed user account. At least 230 customers and roughly 1,500 sites installed the malicious update, with several hundred more downloads possibly affected. Developer Janis Elsts took the site offline after the attacker recompromised the clean 2.36 release; version 2.34 and the free plugin are believed unaffected.

CenterPoint Energy confirms customer data stolen in cyberattack

CenterPoint Energy confirms attackers stole customer personal data, with a threat actor leaking 7.49 million records scraped from an unprotected API.

CenterPoint Energy, a utility serving about 7 million metered customers across Indiana, Minnesota, Ohio, and Texas, confirmed in an SEC filing that an unauthorized third party obtained customer personal information via an external-facing system. A threat actor using the alias "4d722e4d656f77" leaked 7.49 million records containing names, phone numbers, service and billing addresses, account numbers, billing amounts, and partial Social Security numbers. The actor claims the data was exfiltrated by iterating through millions of IDs on CenterPoint's public API, which lacked rate limiting and WAF protections. Electric and gas services were not impacted, but multiple federal class-action lawsuits have already been filed.

BambooToken malware controls Windows and Linux systems via MQTT

Lumen Black Lotus Labs exposes BambooToken, a China-aligned malware framework using MQTT C2 to backdoor Windows and Linux systems at roughly a dozen enterprises.

Lumen's Black Lotus Labs documented BambooToken, a previously unknown malware framework active since at least 2023 that adopted MQTT for command-and-control in 2024-2025 variants targeting Windows and Linux. Infection occurs via DLL side-loading through digitally signed Tendyron OnKey USB-token software or an impersonated Kingsoft Office installer; dead code suggests keylogging, clipboard theft, audio/webcam capture, and screenshot modules. Telemetry identified roughly a dozen compromised entities, mostly in Asia and South America, including a Hong Kong GitLab server and possibly users of the SpeedCN VPN service. Targeting patterns are consistent with China-aligned operations, though no attribution to a known cluster was made.

What Zero-Day Response Should Be in the Post-Mythos Era

Picus Security outlines a zero-day response playbook where defenders simulate exploit technique chains before public PoCs exist.

The article uses PaperCut NG/MF's August incident — exploitation in the wild before any patch, with the first emergency fix bypassed the same day and a third landing September 1 — as the template for AI-accelerated vulnerability response. It walks through a hypothetical CVE-2026-1001 (explicitly made up) to argue defenders should map CVEs to ATT&CK technique chains and simulate them against NGFW, WAF, EDR, endpoint hardening, and SIEM controls within minutes of disclosure. It notes disclosure-to-exploitation time has fallen from 21.5 days to hours.

Twitch extension with 30K installs exposes users’ OAuth tokens

Twitch extension with 30,000+ installs exfiltrates users' OAuth session tokens to Russian-run JeetBot proxy servers.

Socket analysis shows the "Twitch Enhanced Viewer | JeetBot" browser extension, with over 30,000 installs on the official Chrome and Firefox stores, captures the Twitch web client's authorization header and extracts the user's OAuth token. The token is appended as an auth= URL parameter to video playlist requests routed through JeetBot proxy servers, landing in cleartext request logs retrievable by the Russian-language bot service vendor; ten hardcoded Russian-language channels are exempted. Earlier versions used more explicit token exfiltration, and the extension remained live in both stores at publication. Socket recommends removing the extension, disconnecting all Twitch sessions, and re-authenticating.

Hackers hijack HBO Max Reddit account to push malware in ClickFix ads

Hackers hijacked HBO Max's verified Reddit account to run 108 ClickFix ads delivering infostealers and crypto clippers to Windows and macOS users.

Hudson Rock and ADAMnetworks linked the hijacked u/hbomax Reddit account to a campaign they call PasteSwitch, which ran 108 malicious ads over roughly 48 hours pushing sites like hbomaxx.us, codex-craft.com, and code-desktop.com. ClickFix social engineering tricks victims into pasting Base64-obfuscated shell or PowerShell commands into Terminal or Run, delivering MacSync, AMOS helper persistence, Amatera Stealer loaded in-memory, and the AnimateClipper and ZigClipper crypto clipboard hijackers. Windows chains used an MP3/HTA polyglot to create scheduled tasks, disable AMSI, and launch 32-bit PowerShell; fake Ledger, Trezor Suite, and Exodus wallet apps steal recovery phrases. Reddit admins paused the ads, and it remains unclear how the account was accessed.

Hackers exploit Tencent app flaw to deploy GrayRabbit malware

UNC3569 actively exploits one-click RCE in Tencent Sogou Input Method to deploy the GrayRabbit backdoor, patched in version 16.3.0.3498.

Gen Digital reports that China-aligned UNC3569 is actively exploiting CVE-2026-51990, a one-click RCE chain in Tencent Sogou Input Method for Windows, which has hundreds of millions of installations in China. The chain abuses unvalidated command-line argument injection via the sgbiz: URI handler, unrestricted URL navigation in a CEF-based webview, and an unsandboxed outdated Chromium 80 engine to gain code execution and install the GrayRabbit backdoor. The analyzed malware is a mature 64-bit variant with RC4-encoded C2 config supporting reverse shells, file transfer, and reflective plugin loading. Tencent patched the argument validation in version 16.3.0.3498, but the browser engine remains outdated and unsandboxed.
