Actual Job Posting BTW in Dublin, Ireland
so when it comes to fast intelligence gathering of a company its pretty straight forward, there Security team may have "AMAZING" OPSEC (operational security) but every company have one huge issue, and that is how they recruit new people whether by internal HR departments or by hired recruiting teams. These teams need to display the required skills which both unfortunately and fortunately mean a lot of details are put up regarding systems and infrastructure.
Bellow is a posting for a IT Onsite Deskside Engineer for a prominent company who has a heavy hand in Information security (NO I WONT DROP THE NAME)
But from this post we can clearly see some very important details, some of which I have marked in Yellow and list them with reasons bellow.
1 - Dublin = we now have the location to look for when attacking these systems
2 - Datacenter Equipment = so they are running a large network or possible a WAN based network
3 - Win 7 and Win 10 = Ok so we know what OS we will be looking at
4 - MS Office = so we know if we are sending a phishing campaign we know what document type that will be normal to them
5 - Desktops/Printers/Handhelds = Now we know they have multiple different devices belonging to the company in the location.
6 - Active directory = well we know they defiantly have a Target Goal on site
7 - SMS/WebEX/LiveMeeting = ok now we have services we can use to spear phish with
8 - Handheld = Blackberry, Andriod and IOS = now we know the attack surface for the mobile devices for making malicious apps
9 - A+, CCNA, MCTS = we now know the skill level required, windows based servers being used and with the CCNA required there is a high chance they are using Cisco based systems
10 - Experience / Degree = now we know the base level of education/experience the team maybe working with
So I know there is a lot more here, but as I said above QUICK post above. So now we have some solid intelligence to hand over to our RedTeam or for us to build our own attack vectors.
so I hope this quick write up will give you a few ideas, if you need advice or have any questions regarding the above post feel free to ask, im happy to answer them 🙂
