I can see a younger version of myself making something like this and intentionally letting it slip to the media for attention. I th8nk this line is telling: "Since there are no known victims/ targets for the ransomware group, their Tactics, Techniques and Procedures remain unknown."

Don't be dismissive of script kiddies, they can cause a lot of chaos, and often do it because they feel like no amount of self education or self improvement will improve their chances of stable full time employment. (Hence many of them operating out of the former USSR.)
Theres a difference, though, between an extensive ransomeware attack and an experiment by a bunch of amateurs. The chance of key recovery is much greater if there are dedicated criminals behind the attack, but amateurs also don't get the widespread reach that the media coverage might suggest.
I think the characterization of scriptkiddies as hopeless people is a bit romantic. I was something of a skiddie when I was young and I think a lot of their behaviour can be attributed to teenage recklessness.
The former USSR certainly has their fair share of scriptkiddies but they're around in every country. When the USSR was still around, the west had its fair share of phreakers that developed into the hacker subculture and established the code of honour that evolved into the cybersecurity communities of today.
