## Vulnerable Application
|
|
|
|
This module achieves persistence by registering a custom Assistive Technology (AT) in the Windows registry.
|
|
Then it configures the system to launch the AT executable during user logon or desktop switch (such as with
|
|
an admin prived program).
|
|
Requires Windows 8 or higher and administrative privileges.
|
|
|
|
## Verification Steps
|
|
|
|
1. Get session on target with admin/system privs
|
|
2. `use exploit/windows/persistence/assistive_technology`
|
|
3. `set payload <payload>`
|
|
4. `set session <session>`
|
|
5. `exploit`
|
|
6. logon or desktop switch
|
|
7. Get a session
|
|
|
|
## Options
|
|
|
|
### PAYLOAD_NAME
