A China-linked threat cluster has been exploiting vulnerable Roundcube servers at U.S. and Canadian universities to steal credentials and deploy backdoor malware. [...]

Attackers are hiding a data-stealing trojan inside fake exploit code aimed at the people who hunt bugs for a living. The malware, called ChocoPoC, travels in Python proof-of-concept (PoC) repositories on GitHub that claim to exploit hot new CVEs

Gamaredon exploits a WinRAR flaw to drop modular, nearly fileless malware on Ukrainian targets, hiding payloads in Windows streams and resolving C2s via Telegram. Sekoia’s Threat Detection & Research team dropped a YARA rule in late December 2025 to hunt for new initial access vectors, and by January 2026 it had already generated a dozen […]

LLM-Built Toolkit Hit 91 Hosts, Mined Funds in MoneroSecurity researchers detected artificial intelligence-generated malware exploiting the React2Shell vulnerability, allowing attackers with no coding expertise to build functional exploits. The attacker may have circumvented an AI model's safeguards by framing the malicious coding request as homework.

Cybersecurity researchers have discovered a new vulnerability in OpenAI's ChatGPT Atlas web browser that could allow malicious actors to inject nefarious instructions into the artificial intelligence (AI)-powered assistant's memory and run arbitrary code

Malware campaigns distributing the RondoDox botnet have expanded their targeting focus to exploit more than 50 vulnerabilities across over 30 vendors

Cybersecurity researchers have discovered a new ransomware strain dubbed HybridPetya that resembles the notorious Petya/NotPetya malware, while also incorporating the ability to bypass the Secure Boot mechanism in Unified Extensible Firmware Interface (UEFI) systems using a now-patched vulnerability disclosed earlier this year

Attackers Can Upload Malware in System Management Mode and Disable Secure BootMultiple high-severity vulnerabilities in Gigabyte's UEFI firmware could enable attackers to execute arbitrary code within System Management Mode, granting persistent and nearly undetectable control over affected systems, cybersecurity researchers reported.

Cybersecurity researchers are calling attention to a malware campaign that's targeting security flaws in TBK digital video recorders (DVRs) and Four-Faith routers to rope the devices into a new botnet called RondoDox

Cybersecurity researchers have called attention to a new campaign that's actively exploiting a recently disclosed critical security flaw in Langflow to deliver the Flodrix botnet malware

A Chinese-speaking threat actor tracked as UAT-6382 has been linked to the exploitation of a now-patched remote-code-execution vulnerability in Trimble Cityworks to deliver Cobalt Strike and VShell

The actor utilizes custom Linux malware to pursue financial gain, according to Check Point Research

One of most important malware loaders to cybercrims who are jumping on vulnerabilities faster than ever Researchers suspect the criminals behind the Raspberry Robin malware are now buying exploits for speedier cyberattacks.…

Botnet Looks for Vulnerable Internal Network MachinesDelivering more proof that the Log4Shell vulnerability is endemic, Akamai researchers detected botnet malware updated to use the flaw as an infection vector. Log4Shell burst into public awareness in late 2021 when security researchers identified a flaw in the ubiquitous Apache Log4J 2 Java library.

RAT Is Tailored to Exploit Vulnerabilities in Linux Kernel VersionsHackers targeted telecommunications companies in Thailand with a Linux remote access Trojan designed to attack different versions of the open-source kernel, researchers say. Dubbed "Krasue," the malware poses a "severe risk to critical systems and sensitive data," says Group-IB researchers.

A supposed exploit for a notable RCE vulnerability in the popular Windows file-archiving utility delivers a big sting for unwitting researchers and cybercriminals.

​Cybersecurity researchers and threat actors are targeted by a fake proof of concept (PoC) CVE-2023-35829 exploit that installs a Linux password-stealing malware. [...]
