Cybersecurity researchers have uncovered a new evasive malware loader named SquidLoader that spreads via phishing campaigns targeting Chinese organizations. AT&T LevelBlue Labs, which first observed the malware in late April 2024, said it incorporates features that are designed to thwart static and dynamic analysis and ultimately evade detection. Attack chains leverage phishing emails that

The China-nexus cyber espionage actor linked to the zero-day exploitation of security flaws in Fortinet, Ivanti, and VMware devices has been observed utilizing multiple persistence mechanisms in order to maintain unfettered access to compromised environments. "Persistence mechanisms encompassed network devices, hypervisors, and virtual machines, ensuring alternative channels remain available

Chinese-speaking users are the target of a never-before-seen threat activity cluster codenamed Void Arachne that employs malicious Windows Installer (MSI) files for virtual private networks (VPNs) to deliver a command-and-control (C&C) framework called Winos 4.0. "The campaign also promotes compromised MSI files embedded with nudifiers and deepfake pornography-generating software, as well as

A controversial proposal put forth by the European Union to scan users' private messages for detection child sexual abuse material (CSAM) poses severe risks to end-to-end encryption (E2EE), warned Meredith Whittaker, president of the Signal Foundation, which maintains the privacy-focused messaging service of the same name. "Mandating mass scanning of private communications fundamentally

A suspected China-nexus cyber espionage actor has been attributed as behind a prolonged attack against an unnamed organization located in East Asia for a period of about three years, with the adversary establishing persistence using legacy F5 BIG-IP appliances and using it as an internal command-and-control (C&C) for defense evasion purposes. Cybersecurity company Sygnia, which responded to

Legitimate-but-compromised websites are being used as a conduit to deliver a Windows backdoor dubbed BadSpace under the guise of fake browser updates. "The threat actor employs a multi-stage attack chain involving an infected website, a command-and-control (C2) server, in some cases a fake browser update, and a JScript downloader to deploy a backdoor into the victim's system," German

Pakistan has become the latest target of a threat actor called the Smishing Triad, marking the first expansion of its footprint beyond the E.U., Saudi Arabia, the U.A.E., and the U.S. "The group's latest tactic involves sending malicious messages on behalf of Pakistan Post to customers of mobile carriers via iMessage and SMS," Resecurity said in a report published earlier this week. "The goal is

A model can be perfectly innocent, yet still dangerous if the means by which it's packed and unpacked are tainted.

An analysis of a hybrid biometric access system from Chinese manufacturer ZKTeco has uncovered two dozen security flaws that could be used by attackers to defeat authentication, steal biometric data, and even deploy malicious backdoors. "By adding random user data to the database or using a fake QR code, a nefarious actor can easily bypass the verification process and gain unauthorized access,"

The recently identified threat actor uses public registries for distribution and has expanded capabilities to disrupt the software supply chain.
