Objective

In Century Level 1, the goal is to retrieve the build version of the installed PowerShell instance. This value is used as the password to log into Century Level 2.

Once found, you’ll reconnect using century2 as the username and this build version as the password.

Step 1: Connect to the Server

Use SSH to connect to the level:

ssh [email protected]

Password: century1

You’ll drop into a PowerShell prompt.

Step 2: Retrieve the Build Version

This is a classic PowerShell question, one of the easiest ways to find version details is by checking $PSVersionTable.

Run:

$PSVersionTable 

And it will return a table such as:

Name                           Value
----                           -----
PSVersion                      5.1.14393.7870
PSEdition                      Desktop
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0...}
BuildVersion                   10.0.14393.7870
CLRVersion                     4.0.30319.42000
WSManStackVersion              3.0
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1

Here, BuildVersion is the key value. The full version number is your answer:

10.0.14393.7870

That’s what you’ll use as the password to access the next level.

Step 3: Move on to Century Level 2

Now SSH into the next level:

ssh [email protected]

When prompted for a password, enter the full build version you just found:

10.0.14393.7870

If successful, you're into Century Level 2.

• $PSVersionTable is your go-to for internal versioning

Useful Command Recap

Tip

While $PSVersionTable gives us what we need here, don’t forget that [System.Environment]::OSVersion is another tool in our belt for getting Windows version info, and it’ll probably come in handy later.
