Adversaries may create or modify shortcuts that can execute a program during system boot or user login. Shortcuts or symbolic links are used to reference other files or programs that will be opened or executed when the shortcut is clicked or executed by a system startup process. Adversaries may abuse shortcuts in the startup folder to execute their tools and achieve persistence. Although often used as payloads in an infection chain (e.g.

how MITRE says to see it

Detection Strategy for T1547.009 – Shortcut Modification (Windows)

Detection correlates file creation or modification of `.lnk` (shortcut) files in autostart locations with anomalous parent-child process lineage or unsigned binaries. Defenders should watch for LNK creation/modification events outside of known software installations, patch events, or OS updates.

what reduces it

M1038 Execution Prevention. Prevents malicious shortcuts or LNK files from executing unwanted code by ensuring only authorized applications and scripts are allowed to run.
M1018 User Account Management. Limit Privileges for Shortcut Creation: While the SeCreateSymbolicLinkPrivilege is not directly related to.lnk file creation, you should still enforce least privilege principles by limiting user rights to create and modify shortcuts, especially in system-critical locations.
M1022 Restrict File and Directory Permissions. Applying strict permissions to directories where shortcuts are stored, such as the startup folder, can prevent unauthorized modifications.
