Slug

MITRE ATT&CK does not currently catalogue Slug, so this is our assessment of the techniques it uses, drawn from public reporting. The techniques themselves, and every "what that means" definition below, come from MITRE ATT&CK v19.2. Confidence: low. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: slug executes PowerShell scripts to stage payloads and manipulate system processes.

   What that means: Adversaries may abuse PowerShell commands and scripts for execution.

2. T1106 Native API Execution

   What they do: slug leverages native API calls to interact with Windows services and hide malicious activity.

   What that means: Adversaries may interact with the native OS application programming interface (API) to execute behaviors.

3. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: slug modifies registry run keys to ensure persistence across reboots.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

4. T1685 Disable or Modify Tools Defense Impairment

   What they do: slug disables antivirus tools and modifies security configurations to evade detection.

   What that means: Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.

5. T1027.016 Junk Code Insertion Stealth

   What they do: slug inserts junk code into legitimate binaries to bypass static analysis and detection.

   What that means: Adversaries may use junk code / dead code to obfuscate a malware’s functionality.

6. T1070.004 File Deletion Stealth

   What they do: slug deletes Volume Shadow Copies and backup files via command-line tools to prevent recovery.

   What that means: Adversaries may delete files left behind by the actions of their intrusion activity.

7. T1018 Remote System Discovery Discovery

   What they do: slug performs remote system discovery to identify additional targets within the network.

   What that means: Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system.

8. T1021.002 SMB/Windows Admin Shares Lateral Movement

   What they do: slug uses SMB/Windows Admin Shares for lateral movement between compromised hosts.

   What that means: Adversaries may use Valid Accounts to interact with a remote network share using Server Message Block (SMB).

9. T1486 Data Encrypted for Impact Impact

   What they do: slug encrypts victim files using a custom ransomware algorithm to maximize impact.

   What that means: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources.

10. T1490 Inhibit System Recovery Impact

    What they do: slug calls system recovery inhibition commands to lock down backup restoration mechanisms.

    What that means: Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.
