Latest cybersecurity reporting from selected sources.

Cybersecurity researchers have discovered 11 old, Microsoft-signed, Unified Extensible Firmware Interface (UEFI) applications that could be abused to bypass Secure Boot on most systems using the modern firmware standard

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 campaign attributed to a China-linked threat actor known as UAT-8099 that took place between late 2025 and early 2026

Cybersecurity researchers have disclosed a cross-site scripting (XSS) vulnerability in the web-based control panel used by operators of the StealC information stealer, allowing them to gather crucial insights on one of the threat actors using the malware in their operations

The security vulnerability known as React2Shell is being exploited by threat actors to deliver malware families like KSwapDoor and ZnDoor, according to findings from Palo Alto Networks Unit 42 and NTT Security

Unpatched Flaw in Open-Source Gogs Service Facilitates Remote Code ExecutionAn attacker has been exploiting a zero-day vulnerability in Gogs, an open-source and popular Git service that allows for self-hosting, warned researchers. At least 700 internet-exposed servers running Gogs shows signs of being infected with command-and-control malware; no patch is yet available.

The Next Major Cyber Risk Could Come Through a Biological SampleResearchers demonstrated that it is feasible to encode executable payloads into synthetic DNA that, once sequenced and processed, could trigger malware in sequencing software. When a vulnerability in a sequencer becomes a vulnerability in national health or food security, the stakes are existential.

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

AI Actions Bypass Security ToolsArtificial intelligence-powered browsers could expose enterprises to data theft, malware distribution and unauthorized access to corporate apps, new research shows. AI browsers built to complete tasks autonomously lack the security awareness to verify whether an instruction is safe.

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

Cybersecurity researchers have lifted the lid on the threat actors' exploitation of a now-patched security flaw in Microsoft Windows to deploy the PipeMagic malware in RansomExx ransomware attacks

Researchers have released a report detailing how a recent WinRAR path traversal vulnerability tracked as CVE-2025-8088 was exploited in zero-day attacks by the Russian 'RomCom' hacking group to drop different malware payloads. [...]

Oracle Cloud Infrastructure Flaw Enabled Malicious File Uploads, Researchers FoundExploring Oracle Cloud Infrastructure, researchers at Tenable found that Oracle's console-based Code Editor tool failed to block arbitrary file uploads, and could be silently exploited via drive-by attacks to install malware. They said Oracle has now fixed the vulnerability.

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
