Bind Mounts (T1564.013) is a MITRE ATT&CK technique associated with Stealth. Adversaries may abuse bind mounts on file structures to hide their activity and artifacts from native utilities.
Attackers use Bind Mounts because it provides a reliable way to advance their objective within the Stealth tactic, often with a favorable balance of impact versus detectability on Linux environments. Defenders should assess this behavior in the context of the affected platform and adjacent activity rather than treating it as a standalone indicator.
Adversaries may abuse bind mounts on file structures to hide their activity and artifacts from native utilities. A bind mount maps a directory or file from one location on the filesystem to another, similar to a shortcut on Windows. It’s commonly used to provide access to specific files or directories across different environments, such as inside containers or chroot environments, and requires sudo access.
Adversaries may use bind mounts to map either an empty directory or a benign /proc directory to a malicious process’s /proc directory. Using the commands mount –o bind /proc/benign-process /proc/malicious-process (or mount –B), the malicious process's /proc directory is overlayed with the contents of a benign process's /proc directory. When system utilities query process activity, such as ps and top, the kernel follows the bind mount and presents the benign directory’s contents instead of the malicious process's actual /proc directory. As a result, these utilities display information that appears to come from the benign process, effectively hiding the malicious process's metadata, executable, or other artifacts from detection.(Citation: Cado Security Commando Cat 2024)(Citation: Ahn Lab CoinMiner 2023)
No universal command represents Bind Mounts. Capture the exact command line, arguments, parent process, account, host, and execution time from the investigated environment; do not operationalize unverified examples.
| Event ID | Log Channel | What It Indicates |
|---|---|---|
| Not universally applicable | Validate platform coverage | This technique may not produce a Windows event; use telemetry native to the affected platform. |
| Sysmon Event ID | Name | Why It's Relevant Here |
|---|---|---|
| Environment-specific | Validate configured telemetry | Use process, network, file, registry, DNS, or image-load telemetry only when relevant and enabled. |
No MITRE detection guidance published for this technique.
Relevant ATT&CK Data Sources: N/A
A universal Sigma rule would create unreliable results because this technique has no single guaranteed observable. Build detection logic from a documented behavior and supported data source, scope it to the affected platform, and validate it against benign administrative activity before deployment.
Start with the data sources named in the detection section. Scope searches by asset, identity, and time window; correlate the primary behavior with preceding access and subsequent actions. A portable query is intentionally not provided where the technique lacks a universal schema or observable.
No MITRE mitigations mapped to this technique.
