DYSPHOR1A

MITRE ATT&CK does not currently catalogue DYSPHOR1A, 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: DYSPHOR1A executes malicious payloads using PowerShell scripts injected into legitimate processes for command execution.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: DYSPHOR1A disables antivirus tools by terminating security processes and modifying service configurations.

   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. T1027.016 Junk Code Insertion Stealth

   What they do: DYSPHOR1A inserts junk code into binaries to evade static analysis and detection tools.

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

4. T1070.004 File Deletion Stealth

   What they do: DYSPHOR1A deletes Volume Shadow Copies and backup files via vssadmin to prevent recovery.

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

5. T1564.003 Hidden Window Stealth

   What they do: DYSPHOR1A hides malicious processes in hidden windows to avoid user detection during execution.

   What that means: Adversaries may use hidden windows to conceal malicious activity from the plain sight of users.

6. T1003.001 LSASS Memory Credential Access

   What they do: DYSPHOR1A accesses LSASS memory using tools like Mimikatz to steal credentials for persistence.

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

7. T1110 Brute Force Credential Access

   What they do: DYSPHOR1A uses brute-force attacks against local accounts to gain initial access and credentials.

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

8. T1083 File and Directory Discovery Discovery

   What they do: DYSPHOR1A discovers files and directories using Windows Explorer APIs to identify encryption targets.

   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.

9. T1021.002 SMB/Windows Admin Shares Lateral Movement

   What they do: DYSPHOR1A moves laterally across networks by exploiting SMB shares to deploy payloads.

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

10. T1486 Data Encrypted for Impact Impact

    What they do: DYSPHOR1A encrypts victim files using strong symmetric encryption with keys stored in memory.

    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.

11. T1490 Inhibit System Recovery Impact

    What they do: DYSPHOR1A runs commands to inhibit system recovery by disabling automatic repair features.

    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.

12. T1491.001 Internal Defacement Impact

    What they do: DYSPHOR1A displays ransom notes and defaces internal web content to maximize impact and pressure.

    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.
