This is from the latest releases on Vulnhub but it does not have a description.  I think this box was either on the TryHackMe platform or maybe it was accepted to that platform.  The flags are the giveaway and due to their specific look, I don't think it's a coincidence.  Anyway, moving on...

We kick off with Nmap:

We are seeing a ton of email account compromises that are from known sources.  In other words, a vendor, a customer, or an acquaintance, gets compromised.  Frequently, the attacker will reply to an existing email thread from the known source  to you and they will add an attachment or a link.  In that latter scenario, the link is typically leading to a fake credentials page.  This type of attack is so common that we're seeing it several times per week.  It will only get worse. 

With the credentials attack, two-factor authentication (2fa) will typically stop this in its tracks.  You can steal credentials all day long but bypassing 2fa is a much bigger challenge.  And honestly, it's not worth it to the attacker unless the victim has been specifically targeted -- typically not the case.

The description states:  "Difficulty: Easy, Flag: 2 (user & root), Enumeration | Web Application | Privilege Escalation"

Not a complicated box by any means but it has a couple of useful tricks that you will see from time to time in CTF's.  If those are new to you, these are skills worth learning.

First we kick off with Nmap:
