description: Adversaries can abuse winget to download payloads remotely and execute
|
|
them without touching disk. Winget will be included by default in Windows 10 and
|
|
is already available in Windows 10 insider programs. The manifest option enables
|
|
you to install an application by passing in a YAML file directly to the client.
|
|
Winget can be used to download and install exe's, msi, msix files later.
