Cybersecurity researchers have flagged a novel Java-based remote access trojan (RAT) called QuimaRAT that's capable of targeting Windows, Linux, and macOS environments

Cybersecurity researchers have flagged a new malware artifact generated using DeepSeek that constructed a novel attack path combining "unrealistic browser-malware concepts with a real browser capability" to turn it into a working ransomware technique that runs entirely inside the browser on both Windows and Android devices

This week was a reminder that attackers do not always need big tricks. One small mistake, one old access path, one missed patch, and suddenly the door is open

A study by the University of Toronto shows how artificial intelligence can power autonomous worms capable of tailoring attacks against Windows, Linux and IoT devices. A group of researchers from the University of Toronto has demonstrated how open-source artificial intelligence models can be used to create a new category of computer worms capable of autonomously […]

Researchers Trace Linux and Windows Toolsets to Suspected PRC Espionage ActivityNewly discovered malware tied to China-linked actors breached telecom providers across Asia and the Middle East, highlighting growing efforts to gain persistent access into interconnected communications infrastructure.

Cybersecurity researchers have disclosed details of a new Linux malware dubbed Showboat that has been put to use in a campaign targeting a telecommunications provider in the Middle East since at least mid-2022

Cybersecurity researchers have discovered three packages on the Python Package Index (PyPI) repository that are designed to stealthily deliver a previously unknown malware family called ZiChatBot on Windows and Linux systems

TrendAI™ Research breaks down Quasar Linux (QLNX), a previously undocumented sophisticated Linux RAT with low detection rates. In this blog, we examine a full-featured Linux threat incorporating a rootkit, a PAM backdoor, credential harvesting, and more, revealing how this malware enables stealthy access, persistence, and potential supply-chain attacks.

Cybersecurity researchers have flagged malicious Packagist PHP packages masquerading as Laravel utilities that act as a conduit for a cross-platform remote access trojan (RAT) that's functional on Windows, macOS, and Linux systems

Cybersecurity researchers have taken the wraps off a gateway-monitoring and adversary-in-the-middle (AitM) framework dubbed DKnife that's operated by China-nexus threat actors since at least 2019

Too slow react-ion time Baddies are exploiting a critical bug in React Native's Metro development server to deliver malware to both Windows and Linux machines, and yet the in-the-wild attacks still haven't received the "broad public acknowledgement" that they should, according to security researchers.…

Check Point Identifies VoidLink Framework First 'Advanced' AI-Generated ThreatA single developer built a Linux malware framework in less than a week using artificial intelligence, said security researchers. Check Point researchers say this is a case of AI-generated malware reaching operational maturity at a pace that challenges assumptions about development timelines.

Researchers say the advanced framework was built almost entirely by agents, marking a significant evolution in the use of AI to develop wholly original malware.

Sophisticated malware previously thought to be the work of a well-resourced cyber-crime group was built by one person - with the aid of AI tools

The recently discovered sophisticated Linux malware framework known as VoidLink is assessed to have been developed by a single person with assistance from an artificial intelligence (AI) model

AI + skilled malware developers = security threat VoidLink, the newly spotted Linux malware that targets victims' clouds with 37 evil plugins, was generated "almost entirely by artificial intelligence" and likely developed by just one person, according to the research team that discovered the do-it-all implant.…

Researchers discovered a modular, "cloud-first" framework that is feature-rich and designed to maintain stealthy, long-term access to Linux environments.

Detected by Check Point researchers, VoidLink is a sophisticated malware framework that can be used to implant malware in the most common cloud environments
