Cybersecurity researchers have disclosed details of a multi-platform campaign that uses the Message Queueing Telemetry Transport (MQTT) protocol as a communication channel to control Windows and Linux systems. The emerging malware family, codenamed BambooToken, is assessed to be active since at least February 2023 and put to use in attacks targeting organizations across Asia and South America.

With artificial intelligence (AI) shrinking the window between vulnerability discovery and exploitation and lowering the barrier to entry for bad actors, new findings from Sysdig show that skilled human operators can move just as swiftly after gaining initial access. In one instance highlighted by the cloud security company, the threat actor pivoted from a vulnerable Marimo notebook to an SSH

Cybersecurity researchers have disclosed details of a mass-scanning campaign that has targeted Vite deployments siphon sensitive data. The first is an automated effort aimed at internet-exposed Vite development servers that's designed to steal cloud credentials, configurations from Amazon Web Services (AWS) and Microsoft Azure instances, and infrastructure state files, per F5 Labs. The

Cisco has warned that a new critical vulnerability impacting AsyncOS Software for Cisco Secure Email Gateway has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-76461, carries a CVSS score of 9.8 out of a maximum of 10.0. It has been described as a case of insufficient validation in the email parsing logic that could allow an unauthenticated, remote attacker

A Chinese threat actor has been attributed to a spear-phishing campaign that exploits recently patched security flaws in Google Chrome and Microsoft Windows to deliver a malicious JavaScript backdoor called GRIMWEDGE. Volexity, which is tracking the threat cluster under the moniker UTA0560, said the activity targeted multiple non-governmental organizations (NGOs) on September 1, 2026. "The

A suspected Chinese threat actor tracked as Red Heron has been attributed to the rapid exploitation of a recently disclosed security vulnerability in Gitea to compromise internet-facing instances as part of a multi-national campaign. "Red Heron scanned 1,386 Gitea instances across seven countries and maintained a separate dataset of 477 Taiwan-based systems," Acronis Threat Research Unit (TRU)

WordPress has announced it's launching an automated security review for every release of a plugin before it's distributed through the WordPress.org update API so as to analyze it for potential security issues and ensure there are no risks involved. "New plugins are reviewed before they enter the directory, but updates ship continuously after that," David Perez, WordPress Official Plugin

AI keeps showing up in the wrong places. Attackers are using it to speed up exploits, test defenses, and automate more of the job. Some models are also crossing lines on their own. That is not a great combination. The rest of the week is more familiar: old bugs still working, fresh exploit chains, exposed systems, weak defaults, and simple paths that should have been harder to abuse. A few of

A malicious cross-store Twitch browser extension has leaked OAuth tokens associated with nearly 31,000 users to proxy servers operated by a Russian commercial bot service. The extension, named "Twitch Enhanced Viewer | JeetBot," lists HISHIMIRO/jeetbot.cc as its developer and has the following identifiers on the Google Chrome Web Store and Mozilla Firefox Add-Ons store - Chrome -

Microsoft has disclosed details of two campaigns in which threat actors are abusing third-party email delivery infrastructure to blast financial fraud scam messages and using passkey-themed social engineering to breach cloud environments. The first campaign, per the tech giant, involved sending over a million scam emails between August 3 and 5, 2026, by masquerading as chief executive officers

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added five security flaws impacting JFrog Artifactory, ConnectWise ScreenConnect, and MikroTik RouterOS to its Known Exploited Vulnerabilities (KEV) catalog, following reports of active exploitation in the wild. Details of the vulnerabilities are as follows - CVE-2026-42016 (CVSS score: 8.1) - An incorrect authorization

The "major malicious attack" that targeted RubyGems in May 2026 was the work of a swarm of OpenAI agents, according to a new report published by researchers Spencer Kitts, Thomas Larsen, and Sydney Von Arx. On May 12, Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, disclosed details of a coordinated cyber attack that targeted the package manager for the

GitLab has released patches to address multiple flaws, including a maximum-severity security vulnerability that has witnessed in-the-wild probes within hours of public disclosure. The vulnerability in question is CVE-2026-85706 (CVSS score: 10.0), a path traversal issue in the repository commits API that could allow an unauthenticated user to read arbitrary files from the GitLab server under

Anthropic on Thursday said it identified and disrupted industrial-scale illicit distillation attacks against Claude from seven labs based in China, including Alibaba, Moonshot, DeepSeek, Z.ai (aka Zhipu), and MiniMax. Knowledge distillation by itself is a legitimate training method. It refers to a machine learning technique where a large, powerful AI model assumes the role of a "teacher" to

Anthropic has warned that cybercriminals and state-sponsored hackers alike are using its Claude models for cyber attacks, weapons design, propaganda, and mass surveillance between December 2025 and August 2026. The threat actors, which the artificial intelligence (AI) company has branded Generative Threat Groups (GTGs), span state-sponsored groups, financially motivated criminals, commercial

Anthropic on Thursday revealed it disrupted a campaign mounted by a Russian state-sponsored threat actor that abused Claude for developing an AI-assisted workflow to get ahead of the detection curve. The operation has been attributed to a cyber espionage group it calls GTG-20006 (where "GTG" stands for Generative Threat Group), which aligns with broader reporting linking the cluster to Midnight

Microsoft is alerting of a "high-volume phishing campaign" that's using invisible Unicode tag characters to bypass email filters. "Instead of using these characters to hide instructions from people while exposing them to AI models, the attacker used them to split financial lure words such as 'funding' to prevent email filters from parsing them," the Microsoft Security Research team said. The

Threat actors are exploiting two critical security flaws in WordPress plugins Super Forms and Elementor Pro, according to findings from Wordfence. The vulnerabilities in question are - CVE-2026-14894 (CVSS score: 9.8) - A missing file type validation vulnerability in Super Forms – Drag & Drop Form Builder that allows unauthenticated attackers to upload files of any type, including

Plex is urging users to update their instances to the latest version following the release of an update that patches multiple security flaws. The fixes are available in Plex Media Server 1.43.3 and Plex Desktop 1.115.0. The streaming media service did not elaborate on what those issues are, but said CVE identifiers have been requested for them. "We recommend all server owners and Desktop users
