Karma

MITRE ATT&CK does not currently catalogue Karma, 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: low. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: karma executes malicious PowerShell scripts to stage payloads and manipulate system behavior.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: karma disables security tools and monitoring agents to evade detection and analysis.

   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. T1027.013 Encrypted/Encoded File Stealth

   What they do: karma encodes ransom notes and payload components to avoid static detection by antivirus.

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

4. T1070.004 File Deletion Stealth

   What they do: karma deletes Volume Shadow Copies and backup artifacts to eliminate recovery options.

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

5. T1083 File and Directory Discovery Discovery

   What they do: karma scans file and directory structures to identify high-value targets for encryption.

   What that means: Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

6. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: karma exfiltrates sensitive victim data before encryption to increase ransom pressure.

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

7. T1486 Data Encrypted for Impact Impact

   What they do: karma encrypts victim files using a custom ransomware payload to hold data hostage.

   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.

8. T1490 Inhibit System Recovery Impact

   What they do: karma runs commands to halt system recovery processes and prevent 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 breached by Karma ransomware group.
We have extracted valuable or sensitive data from your network and encrypted the data on your systems. 

Decryption is only possible with a private key that only we posses.
Our group's only aim is to financially benefit from our brief acquaintance,this is a guarantee that we will do what we promise.
Scamming is just bad for business in this line of work.

Contact us to negotiate the terms of reversing the damage we have done and deleting the data we have downloaded.
We advise you not to use any data recovery tools without leaving copies of the initial encrypted file.
You are risking irreversibly damaging the file by doing this. 

If we are not contacted or if we do not reach an agreement we will leak your data to journalists and publish it on our website.

If a ransom is payed we will provide the decryption key and proof that we deleted you data.
When you contact us we will provide you proof that we can decrypt your files and that we have downloaded your data.
