Datacarry

MITRE ATT&CK does not currently catalogue Datacarry, 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: datacarry executes PowerShell scripts to stage ransomware payloads and manipulate system processes.

   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: datacarry modifies Registry Run Keys to ensure ransomware execution upon user logon or system startup.

   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: datacarry disables antivirus tools and security monitoring utilities 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. T1027.013 Encrypted/Encoded File Stealth

   What they do: datacarry encodes victim files with custom symmetric encryption routines before demanding ransom payments.

   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: datacarry deletes Volume Shadow Copies and backup directories via command-line utilities to prevent recovery.

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

6. T1110 Brute Force Credential Access

   What they do: datacarry brute-forces local accounts using password lists to gain initial access to victim systems.

   What that means: Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

7. T1135 Network Share Discovery Discovery

   What they do: datacarry scans network shares using native tools to identify victim file servers and data repositories.

   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: datacarry leverages SMB/Windows Admin Shares for lateral movement across networked servers in targeted IT environments.

   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: datacarry encrypts victim files with custom ransomware binaries, targeting communication and marketing data heavily.

   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: datacarry calls system recovery inhibitors like shutdown scripts to disrupt backup restoration attempts.

    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.

Your network has been attacked.
All files have been encrypted with a strong encryption algorithm.
Shadow copies also removed, so F8 or any other methods may damage encrypted data but not recover.
We exclusively have decryption software for your situation.
No decryption software is available in the public. If you wish to try decryption on your own, do it on a file that does not matter.
DO NOT RESET OR SHUTDOWN, files may be damaged.
DO NOT RENAME OR MOVE the encrypted and readme files.
DO NOT DELETE readme files.
This may lead to the impossibility of recovery of the certain files.
We can provide free decryption samples.
To get info (decrypt your files) contact us at: [email protected]
NOTE:
We have also successfully backed up data such as customer information from your databases. We can provide listing.
Ensuring if you DO NOT comply your data will be leaked. (http://dcarryhaih5oldidg3tbqwnde4lxljytnpvberrwgj2vlvunopd46dad.onion/)
Current price: 1 BTC, can be negotiated
Failure to meet the payment will result in your data being leaked to the public.
Failure to contact will result in a dataleak.
