CostaBricks is a loader that was used to deploy 32-bit backdoors in the CostaRicto campaign.[1]
Security context for executives and security teams
S0614: CostaBricks describes [CostaBricks](https://attack.mitre.org/software/S0614) is a loader that was used to deploy 32-bit backdoors in the [CostaRicto](https://attack.mitre.org/groups/G0132) campaign.(Citation: BlackBerry CostaRicto November 2020)
Executive priority
S0614: CostaBricks 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 S0614: CostaBricks 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 S0614: CostaBricks 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.
Generated from the cited source records. This long-tail analysis has not been individually reviewed by a named human.

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 | T1105 | Ingress Tool Transfer | CostaBricks has been used to load SombRAT onto a compromised host.[1] |
| Enterprise | T1027.002 | Software PackingSub-technique | CostaBricks can implement a custom-built virtual machine mechanism to obfuscate its code.[1] |
| Enterprise | T1027.001 | Binary PaddingSub-technique | CostaBricks has added the entire unobfuscated code of the legitimate open source application Blink to its code.[1] |
| Enterprise | T1055 | Process Injection | CostaBricks can inject a payload into the memory of a compromised host.[1] |
| Enterprise | T1106 | Native API | CostaBricks has used a number of API calls, including `VirtualAlloc`, `VirtualFree`, `LoadLibraryA`, `GetProcAddress`, and `ExitProcess`.[1] |
| Enterprise | T1140 | Deobfuscate/Decode Files or Information | CostaBricks has the ability to use bytecode to decrypt embedded payloads.[1] |
Groups, software, and campaigns
C0004: CostaRicto
CostaRicto was a suspected hacker-for-hire cyber espionage campaign that targeted multiple industries worldwide, with a large number being financial institutions. CostaRicto actors targeted organizations in Europe, the Americas, Asia, Australia, and Africa, with a large concentration in South Asia (especially India, Bangladesh, and Singapore), using custom malware, open source tools, and a complex network of proxies and SSH tunnels.[1]

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(3)
| Release | Bundle imported | Object version | Modified | Status | Raw hash |
|---|---|---|---|---|---|
| 20.0 | 1.1 | Current bundle | a398e6df1d75… | ||
| 19.2 | 1.1 | Older bundle | a398e6df1d75… | ||

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.
