Threats Tagged 'node.js'

Multiple ClickFix campaigns were identified employing three distinct delivery mechanisms while sharing common characteristics including DLL sideloading, consistent file-naming conventions, and command-and-control dead drops. The first campaign used remotely hosted MSI packages containing legitimate software to sideload malicious DLLs. The second leveraged NodeJS to execute JavaScript files, while the third utilized Python 3.5 to conceal and execute payloads. All campaigns originated from ClickFix lures and employed aggressive social engineering tactics, including direct phone contact directing victims to compromised WordPress sites. Post-compromise activity included extensive discovery commands and Active Directory enumeration. Infrastructure overlap and tactics indicate connections to the Lorem Ipsum malware family and Vanilla Tempest operations, with potential ransomware deployment as the final objective.

A new ClickFix campaign targets Windows users with a NodeJS-based infostealer delivered via malicious MSI installers. This highly adaptable remote access Trojan minimizes forensic footprints through dynamic capability loading, with core stealing modules and communication protocols delivered in-memory only after C2 connection. The malware routes gRPC streaming traffic over Tor network for persistent, masked bidirectional channels. An operational security failure exposed server-side admin panel protocol definitions, revealing a malware-as-a-service backend designed to manage multiple operators and automate cryptocurrency asset tracking. The modular architecture delivers malicious logic dynamically as strings executed in-memory, bypassing static signature detection while supporting full RAT functionality including shell command execution and wallet tracking.
