This rule performs an indicator of compromise (IOC) sweep for activities associated with the TOPHIT / VHX Harvester / @prime0 NPM typosquatting campaign. It detects known malicious C2 network connections (IPs and URLs), file artifacts (hashes) on endpoints, and suspicious email activity involving specific operator email addresses.

It detects known malicious C2 network connections (IPs and URLs), file artifacts (hashes) on endpoints, and suspicious email activity involving specific operator email addresses.
Detects network activity associated with a malicious NPM package (typosquatting) beaconing to a known C2 server (69.48.229.140) and performing command and control operations, including command polling and data exfiltration, specifically from a Node.js environment.
Detects a sequence of events characteristic of exploitation against RouterOS (CVE-2026-67276/CVE-2026-86060), involving a failed SSH login attempt with the username '-2', followed by the creation of a new user account within the same SSH session, and a successful login with that newly created account.
This rule detects incoming phishing emails that use specific financial or payment-related lures (e.g., 'eft wire transfer', 'invoice receipt') in the subject line or body to entice users into clicking a link that points directly to an executable file, often disguised as a document.

Detects ScreenConnect client processes initiating outbound network connections to external cloud relay addresses (typically *-relay.screenconnect.com) from locations outside of standard Program Files directories. This behavior is indicative of unauthorized, standalone, or adversary-deployed ScreenConnect instances attempting to establish a Command and Control (C2) channel, bypassing standard IT-managed deployment pathways.
