|

Identifies the enable of the full user-mode dumps feature system-wide. This feature allows Windows Error Reporting (WER)
|
|
to collect data after an application crashes. This setting is a requirement for the LSASS Shtinkering attack, which
|
|
fakes the communication of a crash on LSASS, generating a dump of the process memory, which gives the attacker access to
|
|
the credentials present on the system without having to bring malware to the system. This setting is not enabled by
|
|
default, and applications must create their registry subkeys to hold settings that enable them to collect dumps.
