Malware | Breaking Cybersecurity News | The Hacker News

A cluster of nearly 800 malicious packages has been published to the npm registry as part of a new campaign designed to deliver cross-platform malware targeting Windows, Mac, and Linux systems. "These packages appear to use AI slop squatted, or randomly generated typo-squatting package names, but all of them deliver a powerful RAT and infostealer payload," OpenSourceMalware researcher Paul McCarty said . Unlike other npm-oriented software supply chain attacks that make use of lifecycle hooks like preinstall or postinstall to trigger the execution of malicious code, the newly identified packages come with a README that instructs developers to load them with require(), a built-in function to import modules, local files, and third-party packages. The attack leads to the execution of a downloader named WEL1DROPPER , which, when executed, identifies the host operating system and processor architecture and fetches a compatible payload from one of the three Cloudflare Workers...

ClickFix-style attacks are being used to deliver a Go-based malware capable of stealing cryptocurrency assets, as well as browser-stored passwords, Apple iCloud Keychain data, and cached credentials. The macOS-focused infection chain is designed to deliver a shell script that profiles the host and then fetches a macOS malware payload that's compatible with the computer's CPU architecture. "While the malware payload is capable of stealing passwords, its most interesting function is its capability to slowly deplete cryptocurrency accounts, siphoning their contents into accounts under the threat actor's control," Huntress security researcher Andrew Brandt said . The attack chain begins with pasting a ClickFix command into the Terminal app, triggering the execution of a Bash profiler/loader that collects extensive system details and then retrieves a Mach-O payload that matches the victim's processor architecture. The payload is a Go-based stealer that can ...

A new analysis has uncovered that the threat actor tracked as TeamPCP has been active on the cybercrime scene as far back as 2020, indicating the group has been compromising internet-facing infrastructure for years before training their sights on the software supply chain. "The connection is supported by overlapping domains, malware deployment paths, staging techniques, backend infrastructure, and operational tradecraft," Oligo Security researchers Avi Lumelsky and Gal Elbaz said . This includes two campaigns observed in the second half of 2025: ShadowRay 2.0 (aka IronErn), which involved hijacking artificial intelligence (AI) infrastructure into a self-propagating botnet, and TA-NATALSTATUS , which targeted exposed Redis servers to deliver cryptocurrency miners. TA-NATALSTATUS is assessed to be an evolution of a prior campaign that was detailed by Trend Micro in April 2020 that involved targeting Redis servers to deploy malware. This suggests that the threat actor h...

Apparently, opening the thing is now enough. A repo can run before the first prompt, a package can hide among hundreds, and a harmless-looking PDF can finish the job. This week runs on cheap leverage: exposed servers, recycled bugs, poisoned agent instructions, remote-access tools dressed as support software, and trusted defaults doing attackers a favor. Nothing here is especially mystical. Just ordinary systems trusting slightly too much, slightly too early. The full list follows. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Cybersecurity researchers have disclosed details of a "factory-shipped backdoor" implanted in at least 20 Chinese router models from Zbtlink. According to a new report from VulnCheck, the implant appears in all 21 firmware images currently available from Zbtlink that span more than 2 years. The backdoors are designed such that they start automatically and attempt to beacon to Chinese command-and-control (C2) infrastructure as often as every 35 seconds. They masquerade as a Linux kernel thread, but are actually userland processes running with root privileges while blending their true functionality with other legitimate kworker processes. The "phone home" implants have been codenamed ENDLESSDOORS . "ENDLESSDOORS, at its core, is a small tool called rctl (remote control linux)," Jacob Baines, VulnCheck Chief Technology Officer, said. "Uploaded to GitHub on January 14, 2015 and never touched again, this obscure repository implements a simple co...
