S1234: SplatCloak
SplatCloak is a malware that disables EDR-related routines used by Windows Defender and Kaspersky to aid in evading detection. SplatCloak has been deployed by SplatDropper and is known to be leveraged by Mustang Panda since 2025.[1]

Executive priority
S1234: SplatCloak is an official MITRE ATT&CK software. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate S1234: SplatCloak by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (Windows), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
- Network, endpoint, and security-tool telemetry
Detection direction
- Validate whether S1234: SplatCloak appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

How security teams should use this page
Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.
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] |

The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates.
Imported snapshots across ATT&CK releases(2)
| Release | Bundle imported | Object version | Modified | Status | Raw hash |
|---|---|---|---|---|---|
| 19.2 | 1.0 | Current bundle | 0644dff0b22c… | ||
| 19.1 | 1.0 | Older bundle | 0644dff0b22c… |
Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
