The Pentagon bans foreign citizens from accessing highly sensitive data, but Microsoft bypasses this by using engineers in China and elsewhere to remotely instruct American “escorts” who may lack expertise to identify malicious code.
Fun Fact: I once worked with a team that were mapping Iran's internet infrastructure... for reasons. One of the ways we were able to zero in on the more important systems was because we kept finding these weird Cisco routers that had Telnet exposed to the open internet. All of which just so happened to share neighboring IPs (or close enough) with some pretty serious government systems. Fun times.
I'm not a CISCO tech, so I don't know the specifics beyond that. But I do remember that the Telnet connection would permanently ban any IP that failed even a single password attempt. So they had that going for them, I guess lol
Telnet is a nightmare for security since it sends everything in plaintext - even with IP banning, anyone sniffing the network could intercept credentials and payload data without needing to guess passwords at all.
