Pretty interesting, if I'm reading it correctly the existence of the domain is checked, and if is there, the program is aborted, in order to stop sandbox analysis.
I was wondering why they didn't just do a simple variant:
1) Instead of relying on DNS, which anyone can create, why not make a user account on some well known forum site. Like HN or Reddit.
2) Open the site, look for the user's page, and check his message titles by hashing them against some hash that can be in your code.
3) Detonate if you don't see the code, or the user account doesn't exist.
This would have the useful characteristic that you could start/stop the attack using just an internet browser, anywhere. And the code word that you are after would be crypto hashed, so the defenders would have to find your keyword somehow from the hash. Heck, you could confound everyone by turning the thing on or off according to location, time of day, and so on.
For extra points make it a blockchain thing. They're already using that for payment, right?
