Writable Paths
Filesystem paths an account or process can write to, which on Windows and Linux can become privilege-escalation paths if the contents are later executed or read by something more privileged.
Writable paths matter because what an unprivileged process writes can be picked up by a privileged one later. Classic abuses: dropping a malicious DLL where a service searches, writing into a path included in root's PATH, or modifying a configuration file consumed by a privileged daemon. Defenders audit writable paths during hardening reviews and watch for write events to sensitive locations. As an OS-defenders topic, writable-path analysis is core to recognizing many privilege-escalation paths.

Examples
- Auditing world-writable paths during a Linux hardening review.
- Identifying writable directories on Windows that elevated services search.
- Watching for unexpected writes to sensitive paths during investigation.
