Techniques used
This mirrors the MITRE pattern of making group, software, campaign, and technique relationships scannable. Relationship notes come from mirrored ATT&CK relationship text when available.
| Domain | ID | Name | Relationship / procedure |
|---|---|---|---|
| Enterprise | T1685 | Disable or Modify Tools | SplatCloak has identified and disabled API callback features of Windows Defender and Kaspersky.[1] |
| Enterprise | T1082 | System Information Discovery | SplatCloak has collected the Windows build number using the windows kernel API `RtlGetVersion` to determine if the response is 19000 or higher (Windows 10 version 2004 or later).[1] |
| Enterprise | T1518.001 | Security Software DiscoverySub-technique | SplatCloak has identified drivers of AV solutions by searching for related filenames, keywords and signed certificates.[1] |
| Enterprise | T1036.001 | Invalid Code SignatureSub-technique | SplatCloak has used a revoked certificate to exploit Windows driver execution policy where certificates issued before a specific date could still load.[1] |
| Enterprise | T1083 | File and Directory Discovery | SplatCloak has used Windows API to identify files associated with Windows Defender and Kaspersky.[1] |
| Enterprise | T1106 | Native API | SplatCloak has utilized Native Windows API calls dynamically through `ZwQuerySystemInformation`.[1] |
