Malware

Mivast

Mivast is a Windows malware family associated with remote shell access, credential harvesting, and Registry-based persistence. It can open a remote shell and execute basic commands on compromised hosts, giving operators interactive post-compromise control. It has also been documented gathering NTLM password information, indicating credential-access functionality focused on Windows authentication material. For persistence, Mivast creates an autostart entry under the Windows Registry Run mechanism so it will execute when the system starts or a user logs on. The available evidence supports classifying Mivast as a remote-access-oriented implant used for post-exploitation on Windows systems.

MITRE ATT&CK

Techniques & procedures

5 distinct techniques documented for this family, organized by ATT&CK tactic.

Execution

1 technique

T1059.003Windows Command ShellEvidence4

Numerous entries state malware can create a remote shell or reverse shell, for example 4H RAT, BLACKCOFFEE, DarkComet, PlugX, QuasarRAT, and others. | The content repeatedly describes threat actors and malware using cmd.exe, the Windows command shell, to execute commands, launch payloads, run batch files, and automate actions on compromised hosts.

Persistence

2 techniques

T1112Modify RegistryEvidence1

Across the content, malware repeatedly 'adds Registry Run keys', 'creates Registry entries', 'modifies the Windows Registry', or 'overwrites registry keys' to maintain persistence.

T1547.001Registry Run Keys / Startup FolderEvidence7

The content repeatedly describes malware and threat actors establishing persistence by adding values under Registry Run keys such as HKCU\Software\Microsoft\Windows\CurrentVersion\Run and HKLM\Software\Microsoft\Windows\CurrentVersion\Run, and by placing shortcuts or files in Startup folders.

Privilege Escalation

1 technique

T1547.001Registry Run Keys / Startup FolderEvidence7

Defense Impairment

1 technique

T1112Modify RegistryEvidence1

Across the content, malware repeatedly 'adds Registry Run keys', 'creates Registry entries', 'modifies the Windows Registry', or 'overwrites registry keys' to maintain persistence.

Credential Access

1 technique

T1003.002Security Account ManagerEvidence1

Command and Control

1 technique

T1105Ingress Tool TransferEvidence2

The content repeatedly describes malware and threat actors that can "download files from C2," "download additional payloads," "upload and download files," "retrieve payloads from the C2 server," and "copy files to remote machines."
