S0564: BlackMould
BlackMould is a web shell based on China Chopper for servers running Microsoft IIS. First reported in December 2019, it has been used in malicious campaigns by GALLIUM against telecommunication providers.[1]

Executive priority
S0564: BlackMould 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 S0564: BlackMould 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 S0564: BlackMould 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.

| Enterprise | T1071.001 | Web ProtocolsSub-technique | BlackMould can send commands to C2 in the body of HTTP POST requests.[1] |
| Enterprise | T1005 | Data from Local System | BlackMould can copy files on a compromised host.[1] |
| Enterprise | T1083 | File and Directory Discovery | BlackMould has the ability to find files on the targeted system.[1] |
| Enterprise | T1105 | Ingress Tool Transfer | BlackMould has the ability to download files to the victim's machine.[1] |
Groups, software, and campaigns
G0093: GALLIUM
GALLIUM is a cyberespionage group that has been active since at least 2012, primarily targeting telecommunications companies, financial institutions, and government entities in Afghanistan, Australia, Belgium, Cambodia, Malaysia, Mozambique, the Philippines, Russia, and Vietnam. This group is particularly known for launching Operation Soft Cell, a long-term campaign targeting telecommunications providers.[1] Security researchers have identified GALLIUM as a likely Chinese state-sponsored group, based in part on tools used and TTPs commonly associated with Chinese threat actors.[1][2][3]

Object version and sync metadata
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 | f2b6001ab5f5… | ||
| 19.1 | 1.0 | Older bundle | f2b6001ab5f5… |
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.
