|
Generates a .webarchive file for Mac OS X Safari that will attempt to
|
|
inject cross-domain Javascript (UXSS), silently install a browser
|
|
extension, collect user information, steal the cookie database,
|
|
and steal arbitrary local files.
|
|
|
|
When opened on the target machine the webarchive file must not have the
|
|
quarantine attribute set, as this forces the webarchive to execute in a
|
|
sandbox.
