Cybersecurity and intelligence agencies from South Korea and the U.S. warned of Gunra ransomware attacks targeting critical infrastructure sectors and organizations across the world. Targets of these attacks include healthcare and public health, financial services, government services and facilities, and professional and nonprofit services. "Gunra is another variant in the ongoing trend of ransomware attacks causing disruption and harm to U.S. and international organizations," CISA Acting Executive Assistant Director for Cybersecurity, Chris Butera, said. Attacks deploying the ransomware have leveraged security flaws in internet-facing Schneider Electric PowerLogic P5 ( CVE-2024-5559 ) and Fortinet FortiOS and FortiProxy ( CVE-2025-24472 ) appliances to obtain initial access, and then deploy the Gunra ransomware as part of a double extortion model that combines data exfiltration and data encryption for maximum impact. Victims who refuse to pay up within five to sev...

Cybersecurity researchers have warned of a supply chain compromise impacting WordPress plugin vendor BdThemes, prompting the content management systems (CMS) platform's plugins team to temporarily disable their downloads. "Unlike traditional software supply chain attacks, zero source code files were modified within the official WordPress.org repository," Wordfence researcher Paolo Tresso said . "Instead, threat actors poisoned a static remote JSON data stream fetched by an administrative promotional banner component." The list of affected plugins is below - Element Pack Addons for Elementor – Elementor Widgets, Elementor Templates, Elementor Addons [bdthemes-element-pack-lite] - 100,000+ active installs Live Copy Paste for Elementor – Cross Domain Copy Paste & Page Duplicator [live-copy-paste] - 6,000+ active installs Pixel Gallery Addons for Elementor – Easy Grid, Creative Gallery, Drag and Drop Grid, Custom Grid Layout, Portfolio Gallery [p...

A lot of security problems still begin with someone doing a completely normal thing. Cloning a repo. Answering a call. Leaving a box exposed. Trusting the default. That pretty much covers the mood this week. Old bugs are back, supply chains are getting stranger, and some exploit paths are so short you wonder what was supposed to stop them in the first place. That’s only part of it. Here’s everything else that made the Monday recap. ⚡ Threat of the Week Anthropic's Model Attempts to Poison Open-Source Project — A new evaluation conducted by the U.K. AI Security Institute (AISI) found that AI models with access to the internet reached out into the real world to target individuals and organizations autonomously across 10 of the total of 122 runs. Of 19 such actions recorded, 17 originated from Anthropic's Mythos 5 and the remaining two involved OpenAI's GPT-5.6-Sol with cyber classifiers. In the most serious case, Anthropic's Claude Mythos 5 spent 34 hours trying...

North Korea's state hackers are no longer content to type prompts into public chatbots. One of the country's main espionage groups has begun running artificial intelligence (AI) offline on its own servers, connecting document-search tools to files in its possession, and collecting the software parts needed to build AI into its malware. South Korean security firm Genians says it uncovered the setup after months of tracking and log analysis on infrastructure tied to Kimsuky, a hacking unit under North Korea's Reconnaissance General Bureau. Genians found no evidence that the group had trained an AI model of its own, and the firm does not offer that as reassurance. It describes an actor in a "research and knowledge acquisition" stage, assembling and testing existing tools rather than making new models, with the apparent aim of folding AI through the operation, from writing malware to analyzing data. For an intelligence unit that has spent years phishing governm...

The threat actor known as Head Mare has been observed weaponizing security flaws in unpatched TrueConf servers once again in attacks targeting Russian companies spanning instrumentation, electronics, transport, energy, IT, and software development sectors. Russian cybersecurity vendor Kaspersky said it detected the attacks in July 2026. The activity involves exploiting a vulnerability chain in the TrueConf videoconferencing server to replace the original TrueConf client installers with poisoned versions that deliver the PhantomCore backdoor and remote access trojan (RAT) into susceptible systems. The vulnerabilities, tracked as KLCERT-26-057 and KLCERT-26-058, enable arbitrary code execution with elevated privileges. The attack impacts TrueConf server versions 5.3.x up to 5.3.9, 5.4.x up to 5.4.9, 5.5.x up to 5.5.5, and earlier. The attack chain is as follows - Attackers connect to the TrueConf server on TCP port 4307, which is open by default. Upon successful conn...
