my tweets are severely limited by my lack of understanding of what I am doing.
There's a bunch of key ones which are embedded everywhere. They have IPsec VPNs to customer factory networks for support.

Tip - if you want in to a bunch of factory networks, don't target the companies - target their ICS suppliers. Find names via case studies.

They will say they have 2FA etc. Find engineer on LinkedIn. Send a Word doc with macro RAT. Boom - you're behind firewalls.

Because vendors usually self managed black box VPN appliances at sites, the actual company doesn't see logs = doesn't know they are owned.

The vendors engineers are just that, engineers for XYZ piece of factory kit. They aren't Infosec. It's a neat design gap for 'air gap'.

The solution is to insist vendors use a company managed remote access system, which you monitor. Far easier said than done.

Yus- the problem is if somebody is coming in via vendor, they may well want access to that vendors kit. All good fun.

Yes. If your vendor enforces his VPN solution, you're buying this risk together with its gear.
