Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
12 distinct techniques documented for this family, organized by ATT&CK tactic.
The attackers also try to achieve persistence so the loader drops some redundant scripts... .5p4rk3l5 is a crontab file that executes .93joshua and .k93
adding a SSH key to authorized_keys (attackers cycled through three different keys depending on the script)
creating a user and adding it to the sudo group; various names are used: gh0stx, sclipicibosu, mexalzsherifu
creating a systemd service called myservice which runs the /usr/bin/sshd script

The loader gathers system information and relays it to the attacker using an HTTP POST to a Discord webhook... After a successful authentication, the following bash commands are executed in the session with the purpose of collecting system information: uname -s -v -n -r -m
