It was an HP Network Printer. That printer had an operating system and a web server on it. Every HP Network Printer came with that. At least back then.
The consultant was able to connect to the printer and use it as a proxy to connect to other systems outside the bank, which he then used to stalk his ex-girlfriend.
He thought he could hide the connection from his bank issued laptop to the Network Printer, and then to systems outside the bank. Obviously he wasn't.
It's been at least 10 years ago now since that happend so some of the details are lost to me now. The above is what I can remember. Other details have faded from memory.
ok no problem
