Malware

Wiarp

Wiarp is a backdoor malware family. Based on the provided content, it creates a backdoor that allows remote attackers to create a service, inject files into running processes, and open a command line interface on compromised systems. These behaviors indicate capabilities for persistence via service creation, code or payload injection into active processes, and remote command execution. The provided content does not identify a specific threat actor, infection vector, targeted industry, targeted geography, or concrete indicators of compromise.

MITRE ATT&CK

Techniques & procedures

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

Execution

1 technique

T1059.003Windows Command ShellEvidence4

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

1 technique

T1543.003Windows ServiceEvidence2

“Sandworm Team used an arbitrary system service to load at system boot for persistence for Industroyer… replaced the ImagePath registry value of a Windows service with a new backdoor binary… [multiple groups/malware] creating a service / installing as a service / modifying service configurations for persistence.”

Privilege Escalation

2 techniques

T1055Process InjectionEvidence5

The content repeatedly describes malware and threat actors injecting shellcode, DLLs, or payloads into legitimate processes such as svchost.exe, explorer.exe, iexplore.exe, cmd.exe, lsass.exe, and browser processes.

T1543.003Windows ServiceEvidence2

Stealth

1 technique

T1055Process InjectionEvidence5

Lateral Movement

1 technique

T1021.002SMB/Windows Admin SharesEvidence1

OilRig has used a compromised Domain Controller to create a service on a remote host.

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."
