Redalert

MITRE ATT&CK does not currently catalogue Redalert, 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. T1059.001 PowerShell Execution

   What they do: redalert executes PowerShell scripts to stage payloads and manipulate system processes during initial compromise.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: redalert disables antivirus tools by terminating security processes and modifying service 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.

3. T1070.004 File Deletion Stealth

   What they do: redalert deletes Volume Shadow Copies and recycle bins via vssadmin and command-line tools to prevent recovery.

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

4. T1057 Process Discovery Discovery

   What they do: redalert enumerates running processes via tasklist to identify critical services for disruption or privilege escalation.

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

5. T1135 Network Share Discovery Discovery

   What they do: redalert scans network shares using net use commands to identify accessible victim directories for lateral movement.

   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.

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

   What they do: redalert propagates laterally through SMB shares to encrypt additional machines within the victim network.

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

7. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: redalert exfiltrates stolen data via encrypted channels before deployment to enable double extortion.

   What that means: Adversaries may exfiltrate data to a cloud storage service rather than over their primary command and control channel.

8. T1486 Data Encrypted for Impact Impact

   What they do: redalert encrypts victim files using a custom symmetric cipher, targeting documents and backups across affected systems.

   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. T1490 Inhibit System Recovery Impact

   What they do: redalert executes system shutdown commands and service termination scripts to maximize operational disruption.

   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.
