#SmartCustody adversary category “Loss by Crime, Other”

I've spent a lot of time on the category of THEFT, but it's not the only sort of crime that can impact your cryptocurrency holdings. There's a whole other category, which I wittily called LOSS BY CRIME, OTHER. (1/10)

I place four different adversaries in this #SmartCustody category: Blackmail, Coercion, Terrorism, and Non-Financially-Motivated Attackers. The unifying theme is that they're trying to take your digital assets by illegal means. (2/10)

Yes, some of these OTHER adversaries are still technically THEFT, but they tend to be risks with bigger consequences than just losing property. You could lose your reputation or your life! (3/10)

I iconify these criminals as a man with a overcoat and a shotgun. That's pretty scary too. (4/10)

These can be darker crimes, but they're also somewhat less likely. Are you really likely to be kidnapped? (A form of coercion.) Could you even be blackmailed? I suspect mostly not. (5/10)

But of course the point of #SmartCustody is to anthropomorphize adversaries so that you understand them better, and to use that as the foundation for determining whether they're threats to you (personally) or not. (6/10)

We might viscerally fear being kidnapped for our Bitcoins (or that man in the covercoat), but by modeling the risk we can determine if it's actually likely. If it isn’t, it may be better concentrate our efforts on another risk. (7/10)

The motive of these adversaries is mixed. Like other crimes, greed is a big factor, but the non-fincially-motivated attackers could be hackers, hactivists, or just bored kids. (8/10)

Because of that variation in motive, each of these OTHER crimes have to be approached somewhat differently than we did for the motives of the more pure THEFT crimes. (9/10)

Any thoughts on these OTHER crimes? Any specific adversaries that I missed? Let us know! And please consider supporting the book this is drawn from, #SmartCustody. We're working on V2, with multi-sigs and other expansions: https://smartcustody.btcpay.blockchaincommons.com/ (10/10)
