Shiba

MITRE ATT&CK does not currently catalogue Shiba, 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 v20.0. Confidence: low. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: Shiba executes ransomware payloads using PowerShell scripts to spread and encrypt files across compromised systems.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: Shiba disables antivirus tools and system recovery mechanisms by terminating security processes and modifying service configurations.

   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.

3. T1027.002 Software Packing Stealth

   What they do: Shiba packs its malware binaries to evade signature-based detection during execution.

   What that means: Adversaries may perform software packing or virtual machine software protection to conceal their code.

4. T1070.004 File Deletion Stealth

   What they do: Shiba deletes Volume Shadow Copies and backup directories via built-in Windows commands to prevent recovery.

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

5. T1110 Brute Force Credential Access

   What they do: Shiba brute-forces local accounts using password lists to gain initial access to networked systems.

   What that means: Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

6. T1083 File and Directory Discovery Discovery

   What they do: Shiba performs file and directory discovery using Windows API calls to identify valuable data for encryption.

   What that means: Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

7. T1486 Data Encrypted for Impact Impact

   What they do: Shiba encrypts victim files using custom ransomware binaries, targeting documents and images to maximize disruption.

   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.

8. T1489 Service Stop Impact

   What they do: Shiba stops critical Windows services like backup and monitoring tools using net stop commands to hinder recovery.

   What that means: Adversaries may stop or disable services on a system to render those services unavailable to legitimate users.
