<p>Adversaries may add or modify XDG Autostart Entries to execute malicious programs or commands when a user’s desktop environment is loaded at login. XDG Autostart entries are available for any XDG-compliant Linux system. XDG Autostart entries use Desktop Entry files (
.desktop) to configure the user’s desktop environment upon user login. These configuration files determine what applications launch upon user login, define associated applications to open specific file types, and define applications used to open removable media.</p><p>Adversaries may abuse this feature to establish persistence by adding a path to a malicious binary or command to the Exec directive in the .desktop configuration file. When the user’s desktop environment is loaded at user login, the .desktop files located in the XDG Autostart directories are automatically executed. System-wide Autostart entries are located in the /etc/xdg/autostart directory while the user entries are located in the ~/.config/autostart directory.</p><p>Adversaries may combine this technique with Masquerading to blend malicious Autostart entries with legitimate programs.</p>KEV CVEs mapped to this technique · CTID Mappings Explorer
None. No KEV entry in the public mapping names this technique. Given that 74.7% of KEV has no mapping at all, this says more about the mapping than about the technique.

Detects a phishing attack which expands a ZIP file containing a malicious shortcut.
If the victim expands the ZIP file via the explorer process, then the explorer process expands the malicious ZIP file and drops a malicious shortcut redirected to a backdoor into the Startup folder.
Additionally, the file name of the malicious shortcut in Startup folder contains {0AFACED1-E828-11D1-9187-B532F1E9575D} meaning the folder shortcut operation.
