Majinahanashi

MITRE ATT&CK does not currently catalogue Majinahanashi, 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: majinahanashi executes PowerShell scripts to deploy payloads and manipulate system processes on targeted hosts.

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

2. T1112 Modify Registry PersistenceDefense Impairment

   What they do: majinahanashi modifies Windows Registry Run keys to maintain persistence across reboots on compromised systems.

   What that means: Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.

3. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: majinahanashi uses startup folders to launch ransomware components automatically during user logon.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

4. T1685 Disable or Modify Tools Defense Impairment

   What they do: majinahanashi disables antivirus tools and modifies security utilities to evade detection during lateral movement.

   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.

5. T1070.004 File Deletion Stealth

   What they do: majinahanashi deletes Volume Shadow Copies and backup directories to prevent recovery from ransomware encryption.

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

6. T1083 File and Directory Discovery Discovery

   What they do: majinahanashi uses file and directory discovery to enumerate critical retail and agricultural data paths before 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.

7. T1560.001 Archive via Utility Collection

   What they do: majinahanashi archives stolen retail transaction data using utility tools prior to exfiltration.

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

8. T1486 Data Encrypted for Impact Impact

   What they do: majinahanashi encrypts victim files with impact-oriented payloads targeting e-commerce and healthcare databases.

   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.

9. T1489 Service Stop Impact

   What they do: majinahanashi stops critical Windows services like backup and monitoring tools to maximize disruption.

   What that means: Adversaries may stop or disable services on a system to render those services unavailable to legitimate users.

10. T1490 Inhibit System Recovery Impact

    What they do: majinahanashi inhibits system recovery by corrupting backup services and disabling restore mechanisms.

    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.
