Chinese-speaking threat actors are suspected to have leveraged a compromised SonicWall VPN appliance as an initial access vector to deploy a VMware ESXi exploit that may have been developed as far back as February 2024. Cybersecurity firm Huntress, which observed the activity in December 2025 and stopped it before it could progress to the final stage, said it may have resulted in a ransomware attack. Most notably, the attack is believed to have exploited three VMware vulnerabilities that were disclosed as zero-days by Broadcom in March 2025: CVE-2025-22224 (CVSS score: 9.3), CVE-2025-22225 (CVSS score: 8.2), and CVE-2025-22226 (CVSS score: 7.1). Successful exploitation of the issue could permit a malicious actor with admin privileges to leak memory from the Virtual Machine Executable (VMX) process or execute code as the VMX process. That same month, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the flaw to the Known Exploited Vulnerabilities (KEV) catalog...

Russian state-sponsored threat actors have been linked to a fresh set of credential harvesting attacks targeting individuals associated with a Turkish energy and nuclear research agency, as well as staff affiliated with a European think tank and organizations in North Macedonia and Uzbekistan. The activity has been attributed to APT28 (aka BlueDelta), which was attributed to a "sustained" credential-harvesting campaign targeting users of UKR[.]net last month. APT28 is associated with the Main Directorate of the General Staff of the Armed Forces of the Russian Federation (GRU). "The use of Turkish-language and regionally targeted lure material suggests that BlueDelta tailored its content to increase credibility among specific professional and geographic audiences," Recorded Future's Insikt Group said . "These selections reflect a continued interest in organizations connected to energy research, defense cooperation, and government communication networks r...

As organizations plan for 2026, cybersecurity predictions are everywhere. Yet many strategies are still shaped by headlines and speculation rather than evidence. The real challenge isn't a lack of forecasts—it's identifying which predictions reflect real, emerging risks and which can safely be ignored. An upcoming webinar hosted by Bitdefender aims to cut through the noise with a data-driven outlook on where organizations are already falling short, and what those failures signal for the year ahead. Rather than speculative scenarios, the session focuses on threats that are actively reshaping the attack landscape today. The webinar examines the convergence of three major trends. First, ransomware is evolving beyond opportunistic attacks toward targeted disruptions designed to maximize operational and business impact. Second, the rapid and often uncontrolled adoption of AI within organizations is creating an internal security crisis, eroding traditional perimeter assumptions and exp...

Trend Micro has released security updates to address multiple security vulnerabilities impacting on-premise versions of Apex Central for Windows, including a critical bug that could result in arbitrary code execution.

The U.S. Federal Bureau of Investigation (FBI) on Thursday released an advisory warning of North Korean state-sponsored threat actors leveraging malicious QR codes in spear-phishing campaigns targeting entities in the country. "As of 2025, Kimsuky actors have targeted think tanks, academic institutions, and both U.S. and foreign government entities with embedded malicious Quick Response (QR) codes in spear-phishing campaigns," the FBI said in the flash alert. "This type of spear-phishing attack is referred to as quishing." The use of QR codes for phishing is a tactic that forces victims to shift from a machine that's secured by enterprise policies to a mobile device that may not offer the same level of protection, effectively allowing threat actors to bypass traditional defenses. Kimsuky, also tracked as APT43, Black Banshee, Emerald Sleet, Springtail, TA427, and Velvet Chollima, is a threat group that's assessed to be affiliated with North Korea's...

Cybersecurity researchers have disclosed details of a new campaign that uses WhatsApp as a distribution vector for a Windows banking trojan called Astaroth in attacks targeting Brazil. The campaign has been codenamed Boto Cor-de-Rosa by Acronis Threat Research Unit. "The malware retrieves the victim's WhatsApp contact list and automatically sends malicious messages to each contact to further spread the infection," the cybersecurity company said in a report shared with The Hacker News. "While the core Astaroth payload remains written in Delphi and its installer relies on Visual Basic script, the newly added WhatsApp-based worm module is implemented entirely in Python, highlighting the threat actors' growing use of multi-language modular components." Astaroth, also called Guildma, is a banking malware that has been detected in the wild since 2015, primarily targeting users in Latin America, notably Brazil, to facilitate data theft. In 2024, two diffe...

A China-nexus threat actor known as UAT-7290 has been attributed to espionage-focused intrusions against entities in South Asia and Southeastern Europe. The activity cluster, which has been active since at least 2022, primarily focuses on extensive technical reconnaissance of target organizations before initiating attacks, ultimately leading to the deployment of malware families such as RushDrop, DriveSwitch, and SilentRaid, according to a Cisco Talos report published today. "In addition to conducting espionage-focused attacks where UAT-7290 burrows deep inside a victim enterprise's network infrastructure, their tactics, techniques, and procedures (TTPs) and tooling suggest that this actor also establishes Operational Relay Box (ORBs) nodes," researchers Asheer Malhotra, Vitor Ventura, and Brandon White said . "The ORB infrastructure may then be used by other China-nexus actors in their malicious operations, signifying UAT-7290's dual role as an espionage-motiva...

Cisco has released updates to address a medium-severity security flaw in Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) with a public proof-of-concept (PoC) exploit. The vulnerability, tracked as CVE-2026-20029 (CVSS score: 4.9), resides in the licensing feature and could allow an authenticated, remote attacker with administrative privileges to gain access to sensitive information. "This vulnerability is due to improper parsing of XML that is processed by the web-based management interface of Cisco ISE and Cisco ISE-PIC," Cisco said in a Wednesday advisory. "An attacker could exploit this vulnerability by uploading a malicious file to the application." Successful exploitation of the shortcoming could allow an attacker with valid administrative credentials to read arbitrary files from the underlying operating system, which the company said should be off-limits even to administrators. Bobby Gould of Trend Micro Zero Day Initiative h...

Cybersecurity researchers have discovered three malicious npm packages that are designed to deliver a previously undocumented malware called NodeCordRAT . The names of the packages, all of which were taken down as of November 2025, are listed below. They were uploaded by a user named "wenmoonx." bitcoin-main-lib (2,300 Downloads) bitcoin-lib-js (193 Downloads) bip40 (970 Downloads) "The bitcoin-main-lib and bitcoin-lib-js packages execute a postinstall.cjs script during installation, which installs bip40, the package that contains the malicious payload," Zscaler ThreatLabz researchers Satyam Singh and Lakhan Parashar said. "This final payload, named NodeCordRAT by ThreatLabz, is a remote access trojan (RAT) with data-stealing capabilities." NodeCordRAT gets its name from the use of npm as a propagation vector and Discord servers for command-and-control (C2) communications. The malware is equipped to steal Google Chrome credentials, API tokens,...
