Users of Chinese instant messaging apps like DingTalk and WeChat are the target of an Apple macOS version of a backdoor named HZ RAT. The artifacts "almost exactly replicate the functionality of the Windows version of the backdoor and differ only in the payload, which is received in the form of shell scripts from the attackers' server," Kaspersky researcher Sergey Puzan said. HZ RAT was first

Malicious hackers are exploiting a zero-day vulnerability in Versa Director, a software product used by many Internet and IT service providers. Researchers believe the activity is linked to Volt Typhoon, a Chinese cyber espionage group focused on infiltrating critical U.S. networks and laying the groundwork for the ability to disrupt communications between the United States and Asia during any future armed conflict with China.

Cybersecurity researchers have uncovered a hardware backdoor within a particular model of MIFARE Classic contactless cards that could allow authentication with an unknown key and open hotel rooms and office doors. The attacks have been demonstrated against FM11RF08S, a new variant of MIFARE Classic that was released by Shanghai Fudan Microelectronics in 2020. "The FM11RF08S backdoor enables any

Details have emerged about a China-nexus threat group's exploitation of a recently disclosed, now-patched security flaw in Cisco switches as a zero-day to seize control of the appliance and evade detection. The activity, attributed to Velvet Ant, was observed early this year and involved the weaponization of CVE-2024-20399 (CVSS score: 6.0) to deliver bespoke malware and gain extensive control

Cybersecurity researchers have uncovered a new macOS malware strain dubbed TodoSwift that they say exhibits commonalities with known malicious software used by North Korean hacking groups. "This application shares several behaviors with malware we've seen that originated in North Korea (DPRK) — specifically the threat actor known as BlueNoroff — such as KANDYKORN and RustBucket," Kandji security

A previously undocumented backdoor named Msupedge has been put to use against a cyber attack targeting an unnamed university in Taiwan. "The most notable feature of this backdoor is that it communicates with a command-and-control (C&C) server via DNS traffic," the Symantec Threat Hunter Team, part of Broadcom, said in a report shared with The Hacker News. The origins of the backdoor are

In today's rapidly evolving cyber threat landscape, organizations face increasingly sophisticated attacks targeting their applications. Understanding these threats and the technologies designed to combat them is crucial. This article delves into the mechanics of a common application attack, using the infamous Log4Shell vulnerability as an example, and demonstrates how Application Detection and

Iranian state-sponsored threat actors have been observed orchestrating spear-phishing campaigns targeting a prominent Jewish figure starting in late July 2024 with the goal of delivering a new intelligence-gathering tool called AnvilEcho. Enterprise security company Proofpoint is tracking the activity under the name TA453, which overlaps with activity tracked by the broader cybersecurity

Confidential containers are containers deployed within a Trusted Execution Environment (TEE), which allows you to protect your application code and secrets when deployed in untrusted environments. In our previous articles, we introduced the Red Hat OpenShift confidential containers (CoCo) solution and relevant use cases. We demonstrated how components of the CoCo solution, spread across trusted and untrusted environments, including confidential virtual machine (CVM), guest components, TEEs, Confidential compute attestation operator, Trustee agents, and more, work together as part of the soluti
