What it detects

This rule detects outbound HTTP requests to the transfer.sh file sharing service, an abused staging host from which ScreenConnect exploitation actors retrieve malicious installers and second stage tooling. Enterprise endpoints rarely fetch payloads from transfer.sh, so traffic to this service following suspected exploitation is a useful ingress tool transfer indicator.
