Trinity

MITRE ATT&CK does not currently catalogue Trinity, 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: trinity executes malicious commands via PowerShell scripts to stage payloads and evade detection.

   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: trinity leverages registry run keys to ensure malware execution upon system reboot for persistence.

   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: trinity disables antivirus tools and security software to prevent system recovery and hinder investigations.

   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. T1027.016 Junk Code Insertion Stealth

   What they do: trinity inserts junk code into legitimate binaries to evade static analysis and detection.

   What that means: Adversaries may use junk code / dead code to obfuscate a malware’s functionality.

5. T1070.004 File Deletion Stealth

   What they do: trinity deletes Volume Shadow Copies and backup directories via command-line utilities 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: trinity discovers remote systems across the network to propagate ransomware across victim infrastructure.

   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: trinity scans network shares using native tools to identify additional victims 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.

8. T1560.001 Archive via Utility Collection

   What they do: trinity archives stolen data using utility tools prior to exfiltration for extortion demands.

   What that means: Adversaries may use utilities to compress and/or encrypt collected data prior to exfiltration.

9. T1486 Data Encrypted for Impact Impact

   What they do: trinity encrypts victim files and data using custom ransomware binaries to maximize impact.

   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. T1491.001 Internal Defacement Impact

    What they do: trinity displays internal defacement messages on victim systems to pressure organizations into paying ransoms.

    What that means: An adversary may deface systems internal to an organization in an attempt to intimidate or mislead users, thus discrediting the integrity of the systems.

IMPORTANT INFORMATION!
If you do not write to us within 24 hours, we will start publishing and selling your data on the darknet on hacker sites and offer the information to your competitors. 
Guarantee:If we don't provide you with a decryptor or delete your data after you pay,no one will pay us in the future. We value our reputation. 
Guarantee key:To prove that the decryption key exists, we can test the file (not the database and backup) for free. 
Do not try to decrypt your data using third party software, it may cause permanent data loss. 
Don't go to recovery companies - they are essentially just middlemen.Decryption of your files with the help of third parties may cause increased price (they add their fee to our) we're the only ones who have the decryption keys.
