Ech0raix

MITRE ATT&CK does not currently catalogue Ech0raix, 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: ech0raix uses PowerShell scripts to execute malicious commands and deploy ransomware 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: ech0raix modifies registry run keys to ensure ransomware execution upon system reboot or user login.

   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: ech0raix disables antivirus tools and security software to prevent detection and hinder recovery efforts.

   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. T1027.013 Encrypted/Encoded File Stealth

   What they do: ech0raix encrypts and encodes malicious files to evade signature-based detection during execution.

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

5. T1070.004 File Deletion Stealth

   What they do: ech0raix deletes Volume Shadow Copies and backup files via command-line tools to eliminate recovery options.

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

6. T1018 Remote System Discovery Discovery

   What they do: ech0raix performs remote system discovery to identify high-value targets and network topology before deploying.

   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.

7. T1135 Network Share Discovery Discovery

   What they do: ech0raix scans network shares to discover victim file structures and target directories 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: ech0raix moves laterally through SMB/Windows Admin Shares to infect additional machines within the network.

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

9. T1041 Exfiltration Over C2 Channel Exfiltration

   What they do: ech0raix exfiltrates stolen victim data over encrypted C2 channels before deploying ransomware.

   What that means: Adversaries may steal data by exfiltrating it over an existing command and control channel.

10. T1486 Data Encrypted for Impact Impact

    What they do: ech0raix encrypts victim files using strong symmetric encryption, rendering data inaccessible without a decryption key.

    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.
