A threat actor with ties to the Democratic People's Republic of Korea (aka North Korea) has been observed leveraging the EtherHiding technique to distribute malware and enable cryptocurrency theft, marking the first time a state-sponsored hacking group has embraced the method. The activity has been attributed by Google Threat Intelligence Group (GTIG) to a threat cluster it tracks as UNC5342 , which is also known as CL-STA-0240 (Palo Alto Networks Unit 42), DeceptiveDevelopment (ESET), DEV#POPPER (Securonix), Famous Chollima (CrowdStrike), Gwisin Gang (DTEX), Tenacious Pungsan (Datadog), and Void Dokkaebi (Trend Micro). The attack wave is part of a long-running campaign codenamed Contagious Interview , wherein the attackers approach potential targets on LinkedIn by posing as recruiters or hiring managers, and trick them into running malicious code under the pretext of a job assessment after shifting the conversation to Telegram or Discord. The end goal of these efforts is to ...

A financially motivated threat actor codenamed UNC5142 has been observed abusing blockchain smart contracts as a way to facilitate the distribution of information stealers, such as Atomic (AMOS), Lumma, Rhadamanthys (aka RADTHIEF), and Vidar, targeting both Windows and Apple macOS systems. "UNC5142 is characterized by its use of compromised WordPress websites and 'EtherHiding,' a technique used to obscure malicious code or data by placing it on a public blockchain, such as the BNB Smart Chain," Google Threat Intelligence Group (GTIG) said in a report shared with The Hacker News. As of June 2025, Google said it flagged about 14,000 web pages containing injected JavaScript that exhibit behavior associated with an UNC5142, indicating indiscriminate targeting of vulnerable WordPress sites. However, the tech giant noted that it has not spotted any UNC5142 activity since July 23, 2025, either signaling a pause or an operational pivot. EtherHiding was first documented ...

An investigation into the compromise of an Amazon Web Services (AWS)-hosted infrastructure has led to the discovery of a new GNU/Linux rootkit dubbed LinkPro , according to findings from Synacktiv. "This backdoor features functionalities relying on the installation of two eBPF [extended Berkeley Packet Filter] modules, on the one hand to conceal itself, and on the other hand to be remotely activated upon receiving a 'magic packet,'" security researcher Théo Letailleur said . The infection, per the French cybersecurity company, involved the attackers exploiting an exposed Jenkins server vulnerable to CVE-2024-23897 (CVSS score: 9.8) as the starting point, following which a malicious Docker Hub image named "kvlnt/vv" (now removed) was deployed on several Kubernetes clusters. The Docker image consists of a Kali Linux base along with a folder called "app" containing three files - start.sh, a shell script to start the SSH service and execute the...

Scaling the SOC with AI - Why now?  Security Operations Centers (SOCs) are under unprecedented pressure. According to SACR’s AI-SOC Market Landscape 2025 , the average organization now faces around 960 alerts per day , while large enterprises manage more than 3,000 alerts daily from an average of 28 different tools . Nearly 40% of those alerts go uninvestigated , and 61% of security teams admit to overlooking alerts that later proved critical. The takeaway is clear: the traditional SOC model can’t keep up. AI has now moved from experimentation to execution inside the SOC. 88% of organizations that don’t yet run an AI-driven SOC plan to evaluate or deploy one within the next year. But as more vendors promote “AI-powered SOC automation,” the challenge for security leaders has shifted from awareness to evaluation. The key question is no longer whether AI belongs in the SOC, but how to measure its real impact and select a platform that delivers value without introducing signi...

Cybersecurity researchers have disclosed details of a new campaign that exploited a recently disclosed security flaw impacting Cisco IOS Software and IOS XE Software to deploy Linux rootkits on older, unprotected systems. The activity, codenamed Operation Zero Disco by Trend Micro, involves the weaponization of CVE-2025-20352 (CVSS score: 7.7), a stack overflow vulnerability in the Simple Network Management Protocol (SNMP) subsystem that could allow an authenticated, remote attacker to execute arbitrary code by sending crafted SNMP packets to a susceptible device. The intrusions have not been attributed to any known threat actor or group. The shortcoming was patched by Cisco late last month, but not before it was exploited as a zero-day in real-world attacks. "The operation primarily impacted Cisco 9400, 9300, and legacy 3750G series devices, with additional attempts to exploit a modified Telnet vulnerability (based on CVE-2017-3881 ) to enable memory access," research...
