A campaign identified by the Socket Threat Research team involves 19 malicious browser extensions (18 for Chrome, 1 for Edge) active since February 2024. These extensions deliver a modular malware framework that communicates with command and control servers via WebSocket, strips Content Security Policy headers, and uses cross-site scripting (XSS) injection to execute payloads. The primary goal is to steal cryptocurrency wallet secrets and drain crypto assets, as well as harvest credentials. The threat actor either creates malicious extensions from scratch or compromises legitimate extensions with existing user bases, such as the 'Enable Right Click & Copy' extension with tens of thousands of users. The campaign, named 'Superior,' shows sophisticated and evolving capabilities targeting multiple cryptocurrency platforms and exchanges.

Three distinct implants—SPEAKINGSTONE, DARKLANTERN, and ENDLESSDOORS—have been discovered embedded in ZBT router firmware distributed through a global supply chain reaching the United States, Canada, Australia, Philippines, Germany, and Russia. DARKLANTERN is an unauthenticated UDP backdoor listening on port 9992, offering root shell access from the internet with trivial MAC address bypass. SPEAKINGSTONE is a phone-home surveillance implant that beacons to ZBT's cloud infrastructure, capable of DNS hijacking, ISP credential theft, and remote command execution. A sinkholed backup domain revealed 392 devices, 390 located in China, primarily on China Mobile's network. Internet scans identified 203 DARKLANTERN instances across 22 countries. These implants use plaintext protocols without authentication, making them hijackable by any network adversary. The affected hardware appears in white-labeled consumer products sold through mainstream retailers, representing embedded surveillance capabilities in commerciall...

A path traversal vulnerability affecting the Windows version of WinRAR allows the attackers to execute arbitrary code by crafting malicious archive files. This vulnerability was exploited in the wild and was discovered by Anton Cherepanov, Peter Košinár, and Peter Strýček from ESET.

Between mid-2025 and mid-2026, threat actors using tradecraft associated with ShinyHunters targeted customer SaaS applications, particularly Salesforce instances, through three primary intrusion paths. Voice phishing campaigns impersonated IT support to trick employees into authorizing malicious OAuth applications. Supply chain compromises leveraged trusted integrations including Salesloft, Gainsight, and Klue to obtain OAuth tokens for downstream customer access. Misconfigured guest access enabled exploitation of Aura framework functionality for unauthorized data queries. These techniques abused legitimate OAuth relationships to inherit user and application privileges, enabling enumeration and exfiltration of CRM data while evading authentication detections. The campaigns targeted multiple industries including retail, education, and manufacturing, highlighting risks in OAuth-connected applications and third-party integrations.

In early May 2026, attackers compromised the official JDownloader website by manipulating specific installer download links through the content management system. Between May 6-7, 2026 (UTC), users who downloaded Windows installers via "Download Alternative Installer" links or the Linux shell installer were redirected to malicious third-party files instead of genuine installers. The attackers gained CMS-level access only, not server or filesystem control. The incident was detected on May 7 via Reddit alerts, and the server was immediately taken offline. Malicious links were removed, legitimate links restored, and security hardened before the site resumed normal operations on May 8-9. In-app updates and other download paths remained unaffected. Users who executed downloaded installers during the risk window are advised to perform clean OS reinstalls and change passwords from trusted devices.

Docker and Socket uncovered a supply chain compromise affecting Checkmarx KICS distribution channels. Attackers poisoned official Docker Hub images (tags v2.1.20, v2.1.21, alpine) and VS Code extensions (versions 1.17.0, 1.19.0), introducing unauthorized data exfiltration capabilities. The trojanized KICS binary collects and encrypts scan reports containing credentials from infrastructure-as-code files, transmitting them to external endpoints. Compromised VS Code extensions download mcpAddon.js via Bun runtime, harvesting GitHub tokens, AWS credentials, Azure tokens, npm configurations, and SSH keys. The malware creates public GitHub repositories for staging stolen data, injects malicious GitHub Actions workflows to capture repository secrets, and uses stolen npm credentials to identify writable packages for propagation. TeamPCP appears to claim responsibility for this multi-stage attack designed to steal developer credentials and propagate through CI/CD pipelines.

On April 9, 2026, the cpuid.com website was compromised in a watering hole attack lasting approximately 19 hours. Download URLs for legitimate system administration tools CPU-Z, HWMonitor, HWMonitor Pro, and Perfmonitor 2 were replaced with links to malicious sites distributing trojanized versions. The malicious installers contained legitimate signed executables paired with DLL files named CRYPTBASE.dll that exploited DLL sideloading for C2 communication and payload delivery. Attackers reused infrastructure and code from a March 2026 fake FileZilla campaign, including the STX RAT as the final payload. Over 150 victims were identified globally, primarily individuals but including organizations in retail, manufacturing, consulting, telecommunications and agriculture sectors. The attack demonstrated poor operational security with reused indicators enabling rapid detection.
