A phishing campaign leverages Zoom's document sharing feature to establish initial trust with victims. The attack directs users through a fake bot protection page before presenting a Gmail-like login interface to harvest credentials. Entered credentials are transmitted to the attacker via WebSocket and validated on the backend. This technique exploits user trust in Zoom and mimics legitimate Gmail login to increase success rates. The campaign is currently observed with minimal discussion and no known widespread exploitation. It poses a medium risk due to credential compromise potential without requiring advanced exploitation or vulnerabilities. European organizations using Gmail and Zoom are at risk, especially those with remote workforces relying on these platforms. Attackers can gain unauthorized access to email accounts, leading to data breaches and further attacks. Mitigation requires user awareness, multi-factor authentication enforcement, and monitoring for suspicious login attempts. Countries with high Zoom and Gmail usage and significant remote work adoption are most likely affected.
A new variant of the XCSSET malware, designed to infect Xcode projects, has been identified with key changes in browser targeting, clipboard hijacking, and persistence mechanisms. This variant employs sophisticated encryption and obfuscation techniques, uses run-only compiled AppleScripts for stealthy execution, and expands its data exfiltration capabilities to include Firefox browser data. It also adds another persistence mechanism through LaunchDaemon entries. The malware features a submodule for monitoring the clipboard and substituting wallet addresses. The infection chain consists of four stages, with modifications to the boot function and introduction of new modules. Changes include additional checks for Firefox browser, modified logic for Telegram existence check, and new info-stealer modules targeting Firefox data.

The Iranian threat actor Nimbus Manticore has expanded its operations, targeting defense, telecommunications, and aviation sectors in Western Europe. The group uses sophisticated spear-phishing techniques, impersonating HR recruiters to lure victims to fake career portals. Their toolset includes the MiniJunk backdoor and MiniBrowse stealer, which have evolved to employ advanced evasion techniques like multi-stage DLL sideloading, heavy obfuscation, and code signing. The malware infrastructure leverages Azure App Services for resilient command and control. Nimbus Manticore's recent activities demonstrate increased focus on stealth, operational security, and expanding their targeting to align with Iranian strategic priorities.
A widespread software supply chain attack targeting the Node Package Manager (npm) ecosystem has been discovered, involving a novel self-replicating worm called "Shai-Hulud". The worm has compromised over 180 software packages, including widely used libraries. It operates by harvesting credentials, exfiltrating data, and automatically propagating itself through compromised developer accounts. The attack likely originated from a phishing campaign spoofing npm. The malware scans for sensitive credentials, including npm tokens and cloud service API keys, and publicly exposes them on GitHub. This attack represents a significant evolution in supply chain threats, potentially leading to cloud service compromises, data theft, and lateral movement within networks.

This analysis examines a campaign distributing Atomic macOS Stealer (AMOS), targeting macOS users through fake 'cracked' applications. Attackers use two main delivery methods: malicious .dmg installers and terminal commands that bypass Gatekeeper protection. AMOS employs rotating domains to evade detection and steals a wide range of sensitive data, including credentials, browser information, cryptocurrency wallets, and system files. The campaign demonstrates sophisticated tactics, adapting to macOS security improvements and leveraging social engineering. The report emphasizes the importance of comprehensive endpoint detection, user education, and defense-in-depth strategies to combat such threats.
LAB52 has identified a new backdoor called NotDoor, attributed to APT28, a Russian intelligence-linked threat group. NotDoor is a VBA macro for Outlook that monitors incoming emails for specific trigger words, enabling data exfiltration, file uploads, and command execution on victim computers. The backdoor is deployed via Microsoft OneDrive.exe using DLL side-loading, and it establishes persistence by modifying registry keys. NotDoor employs obfuscation techniques and a custom string encoding method. It can execute commands, exfiltrate files, and upload files to the victim's machine. The malware demonstrates APT28's continuous evolution in bypassing defense mechanisms, posing a significant threat to NATO member countries across various sectors.
