Rise of Darknet Stokes Fear of the Insider

I think there's a book where the setting is that Hell is structured like a corporation.
Presumably because one hired human beings rather than robots.
People do get disgruntled because they are mistreated, but that's because they perceive that they are mistreated. I imagine that we've all worked with people who perceive slights when there are none.
I don't know a good way to detect these hires: generally in the interview people do a decent job of hiding this attitude. Heck, some folks can even make it through a probationary period without showing their true colours!
Their first offering sounds pretty unlikely to yield results and the second seems ethically dubious to undertake for a single client.
I'm betting "apply machine learning to internal... records" looks more like listing the employees with disciplinary records and going "revoke network access from these people".
Like, I get that "disgruntled employee" is less dangerous than "disgruntled employee with expert guidance", but using Tor is already evidence of sophistication. There was nothing stopping these people from going to the library and posting on a normal internet forum, even ten years ago.
Similarly, people stealing all your user information in a movie-style hacker coup is just not that common. Someone flipping a circuit breaker and costing you a bunch of revenue is infinitely more likely, but that's not the headline here because there's no expensive consulting fix for that.
* Disgruntled insiders always have been a security threat, and usually the biggest threat.
* If the seller is operating on open markets, even anonymously, the company has much more visibility into what's happening than before, when the transactions were more private (I assume). The markets must have sufficient liquidity (i.e., buyers) for the seller to succeed, so I would guess that only reasonably well-known darknet markets would be used. Just monitor those markets and you know what is being sold and in many cases can narrow down who the seller is or even catch them and the buyer.
* Fear of a sociopathic 'lone wolf' is often exaggerated. Consider the similar reaction to terrorist attacks: People think, 'anyone could buy a gun and shoot up a crowded place', but that's not how it works. Physically, anyone could do it - anyone could drive their car into a crowd, an opportunity that arises billions of times per day - but people don't do it. The evidence is overwhelming: Human behavior is much safer than we fear.
* I suspect some is an overreaction to an unfamiliar new tech with a scary name: The Darknet.
Also, from another perspective (as you explain), it's actually made it easier to catch such insiders, due to the open nature of these markets (regardless of the fact that they're 'Dark' or believed to be anonymous).

Good news he only received a few offers despite all the privacy tech involved. I wonder what the number would be today. Wikileaks shows it could be significant.
