It was first brought to light by Check Point Research on

Key Findings Arctic Wolf observed a new cluster of automated malicious activity targeting Fortinet FortiGate firewalls since January 15, 2026. The attacks involve the creation of generic user accounts for persistence, configuration changes granting VPN access to those accounts, and exfiltration of firewall configurations. This activity shares similarities with a December 2025 campaign that exploited critical Fortinet authentication bypass vulnerabilities (CVE-2025-59718 and C

Key Findings VoidLink is a sophisticated Linux malware framework, built largely by a single developer with assistance from an artificial intelligence (AI) model. The malware reached over 88,000 lines of code in a short timeframe, showcasing the efficiency enabled by AI-driven development. Operational security failures by the developer exposed development artifacts, providing clear evidence that VoidLink was produced predominantly through AI-driven processes. VoidLink includes

Key Findings Attackers are impersonating LastPass in an active phishing campaign that aims to steal users' master passwords. The phishing emails claim there is urgent LastPass maintenance and urge users to back up their password vaults within 24 hours. The malicious emails use subject lines referencing infrastructure updates, vault security, and missed deadlines to trick victims. The phishing links lead to an Amazon S3–hosted page that redirects to a fake LastPass site design

Key Findings North Korean threat actors associated with the "Contagious Interview" campaign have been observed using malicious Microsoft Visual Studio Code (VS Code) projects as lures to deliver a backdoor on compromised endpoints. The attack involves instructing targets to clone a repository on GitHub, GitLab, or Bitbucket, and launch the project in VS Code as part of a supposed job assessment. The malicious VS Code task configuration files are used to execute payloads, incl

Key Findings Cybersecurity researchers discovered a cross-site scripting (XSS) vulnerability in the web-based control panel used by operators of the StealC information stealer malware. By exploiting the flaw, researchers were able to collect system fingerprints, monitor active sessions, and steal cookies from the infrastructure designed for cookie theft. StealC is a malware-as-a-service (MaaS) offering that emerged in January 2023, leveraging YouTube as a primary distribution

Key Findings GootLoader malware uses malformed ZIP files made of hundreds of concatenated archives to evade detection. GootLoader is used by ransomware actors for initial access, then handed off to others. GootLoader runs on an access-as-a-service model and has been known to deliver threats like SunCrypt, REvil, Kronos, and Cobalt Strike. The ZIP file is intentionally broken so many security and analysis tools can't open it, but Windows can, helping the malware avoid detectio

Key Findings GootLoader malware is using a malformed ZIP archive with 500-1,000 concatenated ZIP files to evade detection The malicious ZIP file is designed to trigger parsing errors in many unarchiving tools, but can still be extracted by the default Windows unarchiver GootLoader employs "hashbusting" techniques by randomizing values in non-critical ZIP file fields to generate unique payloads for each victim The attack involves delivering the malicious ZIP as an XOR-encoded

Key Findings Cybersecurity researchers have discovered five new malicious Google Chrome web browser extensions that impersonate HR and ERP platforms like Workday, NetSuite, and SuccessFactors. The extensions work together to steal authentication tokens, block incident response capabilities, and enable complete account takeover through session hijacking. All five extensions have been removed from the Chrome Web Store, but are still available on third-party software download si

Key Findings A China-linked APT group, tracked as UAT-8837, has been targeting critical infrastructure sectors in North America since at least 2025. The threat actor has recently exploited a critical zero-day vulnerability in Sitecore (CVE-2025-53690, CVSS 9.0) to gain initial access to target networks. After obtaining a foothold, UAT-8837 deploys a range of open-source tools to harvest sensitive information, including credentials, security configurations, and Active Director

Key Findings The FBI warns that the North Korea-linked advanced persistent threat (APT) group Kimsuky is targeting governments, think tanks, and academic institutions with "quishing" attacks. Quishing is a social engineering attack that uses malicious QR codes to trick victims into visiting fake websites or downloading malware. Kimsuky has conducted spear-phishing campaigns using QR codes that impersonate trusted figures like foreign advisors, embassy staff, and think tank em

Key Findings: Chinese-speaking threat actors leveraged a compromised SonicWall VPN appliance as an initial access vector to deploy a VMware ESXi exploit toolkit. The toolkit targeted up to 155 ESXi builds and enabled virtual machine (VM) escape via disabled VMCI drivers and unsigned kernel drivers, potentially paving the way for a ransomware attack. The exploit chain included a sophisticated VM escape and appears to have been developed more than a year before the related VMwa

Key Findings China-linked threat actor UAT-7290 has conducted espionage attacks since at least 2022, targeting South Asia and Southeastern Europe UAT-7290 primarily targets telecom providers, conducting espionage by deeply embedding in victim networks and operating Operational Relay Box (ORB) infrastructure The threat actor uses a broad toolset, including open-source tools, custom malware, and one-day exploits against edge networking devices Attacks are preceded by extensive

Key Findings Researchers from Zscaler ThreatLabz discovered three malicious npm packages that deliver a new Remote Access Trojan (RAT) called NodeCordRAT. The packages - bitcoin-main-lib, bitcoin-lib-js, and bip40 - were designed to mimic legitimate tools from the bitcoinjs project, tricking developers into installing them. NodeCordRAT uses Discord as a command-and-control (C2) channel, blending its malicious traffic with legitimate user activity to evade detection. The malwa

Key Findings The Astaroth banking Trojan is spreading in Brazil through a WhatsApp worm that automatically sends malicious messages to victims' contacts. The malware uses a Python-based propagation module to harvest the victim's WhatsApp contacts and automatically forward infected ZIP files, enabling self-spreading capabilities. A separate banking module operates silently in the background, monitoring the victim's browsing activity and stealing credentials when banking-relate

Key Findings The Russia-aligned threat actor known as UAC-0184 (also tracked as Hive0156) has been targeting Ukrainian military and government entities by leveraging the Viber messaging platform to deliver malicious ZIP archives. The attack campaign involves using Viber to distribute malicious ZIP files disguised as official Ukrainian parliamentary documents and military casualty data. The ZIP archives contain Windows shortcut (LNK) files posing as Microsoft Word and Excel do
