<p>Adversaries may abuse authentication packages to execute DLLs when the system boots. Windows authentication package DLLs are loaded by the Local Security Authority (LSA) process at system start. They provide support for multiple logon processes and multiple security protocols to the operating system.</p><p>Adversaries can use the autostart mechanism provided by LSA authentication packages for persistence by placing a reference to a binary in the Windows Registry location <code>HKLM\SYSTEM\CurrentControlSet\Control\Lsa\</code> with the key value of <code>"Authentication Packages"=<target binary></code>. The binary will then be executed by the system when the authentication packages are loaded.</p>

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.
