MITRE ATT&CK

Techniques & procedures

3 distinct techniques documented for this family, organized by ATT&CK tactic.

Execution

1 technique
T1053Scheduled Task/JobEvidence1

It checks for the existence of specific files and directories associated with a persistent backdoor, including configuration paths under $HOME/.config/sysmon/ and files in /tmp/. It also verifies if a user service named sysmon.service is active using systemctl.

Persistence

2 techniques
T1053Scheduled Task/JobEvidence1

It checks for the existence of specific files and directories associated with a persistent backdoor, including configuration paths under $HOME/.config/sysmon/ and files in /tmp/. It also verifies if a user service named sysmon.service is active using systemctl.

T1543Create or Modify System ProcessEvidence2

may install a persistent systemd backdoor that polls for further payloads.

Privilege Escalation

2 techniques
T1053Scheduled Task/JobEvidence1

It checks for the existence of specific files and directories associated with a persistent backdoor, including configuration paths under $HOME/.config/sysmon/ and files in /tmp/. It also verifies if a user service named sysmon.service is active using systemctl.

T1543Create or Modify System ProcessEvidence2

may install a persistent systemd backdoor that polls for further payloads.

Stealth

1 technique
T1036MasqueradingEvidence1

Beyond stealing credentials and achieving persistence, the threat actors also masqueraded their activity as legitimate services like systemd and disguised the threat as a PostgreSQL utility called pgmon.
