ContFR

MITRE ATT&CK does not currently catalogue ContFR, 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: ContFR 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: ContFR modifies registry run keys to ensure ransomware 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: ContFR disables security tools like antivirus software and monitoring agents to evade detection during infection.

   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: ContFR deletes Volume Shadow Copies and backup files via command-line tools to prevent data recovery.

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

5. T1003.001 LSASS Memory Credential Access

   What they do: ContFR dumps credentials from the LSASS memory to obtain valid accounts for initial access or privilege escalation.

   What that means: Adversaries may attempt to access credential material stored in the process memory of the Local Security Authority Subsystem Service (LSASS).

6. T1018 Remote System Discovery Discovery

   What they do: ContFR discovers remote systems via network scanning to propagate ransomware across the victim environment.

   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: ContFR performs network share discovery to identify accessible file shares for lateral movement and data targeting.

   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: ContFR uses SMB/Windows Admin Shares for lateral movement to infect additional hosts within the network.

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

9. T1486 Data Encrypted for Impact Impact

   What they do: ContFR encrypts victim files and data using strong symmetric encryption to maximize impact and ransom demand.

   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. T1490 Inhibit System Recovery Impact

    What they do: ContFR runs commands to inhibit system recovery processes like Windows restore points and backup services.

    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.
