Latest cybersecurity reporting from selected sources.

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

China-linked FishMonger used two SprySOCKS Windows variants that leveraged kernel drivers and the Print Spooler to target governments in four countries. ESET researchers have found two previously undocumented Windows versions of SprySOCKS, a backdoor that the security community had until now treated as Linux-only. Trend Micro first documented the Linux variant in September 2023 and […]

Cybersecurity researchers have flagged two previously undocumented Windows variants of what was believed to be a Linux-only backdoor called SprySOCKS

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 disclosed details of a new Linux backdoor named PamDOORa that's being advertised on the Rehub Russian cybercrime forum for $1,600 by a threat actor called "darkworm." The backdoor is designed as a Pluggable Authentication Module (PAM)-based post-exploitation toolkit that enables persistent SSH access by means of a magic password and specific TCP port combination.

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 disclosed details of a malicious Go module that's designed to harvest passwords, create persistent access via SSH, and deliver a Linux backdoor named Rekoobe

In this blog entry, Trend™ Research provides a comprehensive breakdown of GhostPenguin, a previously undocumented Linux backdoor with low detection rates that was discovered through AI-powered threat hunting and in-depth malware analysis.

Cybersecurity researchers have discovered two new malware families, including a modular Apple macOS backdoor called CHILLYHELL and a Go-based remote access trojan (RAT) named ZynorRAT that can target both Windows and Linux systems

Cybersecurity researchers have shed light on a novel attack chain that employs phishing emails to deliver an open-source backdoor called VShell

'Plague' malware has been around for months without tripping alarms Researchers at German infosec services company Nextron Threat have spotted malware that creates a highly-persistent Linux backdoor and say antivirus engines do not flag the code as malicious.…

Cybersecurity researchers have flagged a previously undocumented Linux backdoor dubbed Plague that has managed to evade detection for a year

Cybersecurity researchers have unearthed a new controller component associated with a known backdoor called BPFDoor as part of cyber attacks targeting telecommunications, finance, and retail sectors in South Korea, Hong Kong, Myanmar, Malaysia, and Egypt in 2024

Cybersecurity researchers have flagged a new malware campaign that infects Windows systems with a Linux virtual instance containing a backdoor capable of establishing remote access to the compromised hosts

Chinese Hackers Have Used DinodasRATHackers are using a new version of a backdoor to target Linux servers and gain and maintain access in what appears to be an espionage campaign, warn researchers from Kaspersky. The hallmark of DinodasRAT's strategy is its sophisticated victim identification and persistence mechanisms.

Cybersecurity researchers have identified a set of 116 malicious packages on the Python Package Index (PyPI) repository that are designed to infect Windows and Linux systems with a custom backdoor

In a sign that cybersecurity researchers continue to be under the radar of malicious actors, a proof-of-concept (PoC) has been discovered on GitHub, concealing a backdoor with a "crafty" persistence method

A previously undocumented and mostly undetected variant of a Linux backdoor called BPFDoor has been spotted in the wild, cybersecurity firm Deep Instinct said in a technical report published this week

An estimated one million WordPress websites have been compromised during a long-lasting campaign that exploits "all known and recently discovered theme and plugin vulnerabilities" to inject a Linux backdoor that researchers named Balad Injector. [...]

Researchers who discovered the backdoor Linux malware say it may have been around for more than three years — and it targets 30+ plug-in bugs.
