Ranstreet

MITRE ATT&CK does not currently catalogue Ranstreet, 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: ranstreet uses PowerShell commands to execute malicious payloads across compromised systems.

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

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

   What they do: ranstreet modifies registry run keys to maintain persistence after reboot.

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

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: ranstreet disables security tools like antivirus software 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.

4. T1070.004 File Deletion Stealth

   What they do: ranstreet deletes Volume Shadow Copies and backup files 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: ranstreet brute-forces local accounts to gain initial access to victim networks.

   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: ranstreet scans file and directory structures to identify targets 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. T1021.002 SMB/Windows Admin Shares Lateral Movement

   What they do: ranstreet 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).

8. T1486 Data Encrypted for Impact Impact

   What they do: ranstreet encrypts victim files using a custom ransomware payload to hold data hostage.

   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.

9. T1489 Service Stop Impact

   What they do: ranstreet stops critical Windows services to disrupt system functionality during impact.

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

10. T1490 Inhibit System Recovery Impact

    What they do: ranstreet executes scripts to inhibit system recovery processes after encryption.

    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.
