Reading a book on defectors and spies there are three levers to recruitment


Money is the most common one and foreign services are good at targeting it, they learn about their targets through rumors and internet hacking. They position a nice sum of money to motivate.


Ideology - Was huge in the last century, it was easy to find people sympathetic to for example communism and they were the most willing participants. They also became the best recruiters to build a spy network.


Loneliness/Sex - You find the outcast or the lonely and you basically offer him or her companionship, a sympathetic ear, a shoulder to cry on, or a ideal mate, this one usually takes the longest and is the least certain, but is the most popular in spy movies.


With the above comes blackmail, once you do it once no matter how small, you can never walk away, you're hooked like a dying fish.


The most important thing that's promised, is that you'll be protected when things go wrong. There's an escape plan in place. But that's rarely true.


I would expect with the current case, that we're going to find out that he was in debt and got money to bail himself out.
