Sub-technique of: T1564
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.
Platforms: Linux
Identify Attack Surface: Determine if the target environment is susceptible to Bind Mounts by examining the target platforms (Linux).
Assess Existing Defenses: Review whether mitigations for T1564.013 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.
No specific mitigations documented for this technique.
