And now we are logged in as BlackCat

We can see a lot of stuff in the attachments `testing.zip` , `DevTools.zip` and `SSH-TOTP documentation.pdf`. The documentation explains how the authentication for Linux Bay will work so digging through those archives I found a table
<img src="https://imgur.com/voao9nv.png"/>
As we can see the username is `architect` but the method of logging in with SSH is TOTP (Time-based One-Time Password). So in order to login our time must be synced so type this in your terminal
`timedatectl set-timezone UTC`
Then run `ntp_syncer.py`

But before running the `timeSimulatorClient.py` check the code that what it is doing

We can see that `sharedSecret` isn't used anywhere in the code so let's take a look at one of those diagrams

According to this diagram time zone from three different countries are multipled together then XOR operation is performed between the result that comes from it with the shared token so we need to modifiy the code a little bit and to figure out the correct token also the 3 time zones
```
from datetime import datetime, timedelta
import time
import subprocess
from hashlib import sha256
sharedSecret = 792513759492579
while True:
now = datetime.now()
Ukraine = datetime.now() + timedelta(hours=4, minutes=43)
UkraineCurrentTime = int(Ukraine.strftime("%d%H%M"))
Germany = datetime.now() + timedelta(hours=13, minutes=55)
GermanyCurrentTime = int(Germany.strftime("%d%H%M"))
England = datetime.now() + timedelta(hours=9, minutes=19)
EnglandCurrentTime = int(England.strftime("%d%H%M"))
Denmark = datetime.now() + timedelta(hours=-5, minutes=18)
DenmarkCurrentTime = int(Denmark.strftime("%d%H%M"))
Nigeria = datetime.now() + timedelta(hours=1, minutes=6)
NigeriaCurrentTime = int(Nigeria.strftime("%d%H%M"))
multipliedTime = (UkraineCurrentTime*DenmarkCurrentTime*NigeriaCurrentTime)
print('---------------------------------------')
nOTP = (int(multipliedTime ^ sharedSecret))
sshpass = (sha256(repr(nOTP).encode('utf-8')).hexdigest())
print(sshpass[22:44])
print('---------------------------------------')
# keep updating every second - upon each new minute change OTP ssh code
time.sleep(1)
subprocess.call("clear")
```
So this is the code that gave the right OTP

And we are logged in with OTP

We can find the `user.txt` here
Doing a `sudo-l` we can that this user is allowed to run `awk` as root

And we got root !!
For the ACP pin I ran the find command to search for txt files

This resulted to `718008`

In `/etc` folder I found a file
<img src="https://imgur.com/9sqkXKy.png"/>
But this was named using special characters so if we try to read it bash would give it an error
<img src="https://imgur.com/xAMLMdU.png"/>
By googling a liitle bit on how to read files named with special characters I found this

And on running the python script it gave the root flag
