Scarab

MITRE ATT&CK does not currently catalogue Scarab, 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: medium. Treat it as orientation, not attribution.

1. T1078.002 Domain Accounts Initial AccessPersistencePrivilege EscalationStealth

   What they do: scarab leverages domain accounts to authenticate across networked systems and expand compromise.

   What that means: Adversaries may obtain and abuse credentials of a domain account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.

2. T1078.003 Local Accounts Initial AccessPersistencePrivilege EscalationStealth

   What they do: scarab uses local accounts harvested during initial access to maintain persistence and escalate privileges.

   What that means: Adversaries may obtain and abuse credentials of a local account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.

3. T1059.001 PowerShell Execution

   What they do: scarab executes PowerShell scripts to stage payloads, disable defenses, and propagate across compromised systems.

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

4. T1685 Disable or Modify Tools Defense Impairment

   What they do: scarab disables or modifies security tools such as antivirus and monitoring agents 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. T1027.013 Encrypted/Encoded File Stealth

   What they do: scarab encrypts or encodes victim files with its ransomware algorithm before demanding payment.

   What that means: Adversaries may encrypt or encode files to obfuscate strings, bytes, and other specific patterns to impede detection.

6. T1057 Process Discovery Discovery

   What they do: scarab performs process discovery to identify active services and processes for targeting or disabling.

   What that means: Adversaries may attempt to get information about running processes on a system.

7. T1135 Network Share Discovery Discovery

   What they do: scarab uses network share discovery to locate victim file shares and identify high-value data for encryption.

   What that means: Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement.

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

   What they do: scarab moves laterally via SMB/Windows Admin Shares to copy payloads and encrypt additional systems.

   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: scarab encrypts victim files using its ransomware payload, holding data hostage for ransom demands.

   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: scarab inhibits system recovery by destroying Volume Shadow Copies and backup restore 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.
