Yeah, that was clearly just the group having fun, sounds like it might have been some kind of in-joke. Stuff like keygen music and adding extra fun stuff to your cracks has always been part of the culture. For the most part, while I’m not saying there is zero risk, but as long as it’s from verified groups with good reputation, your pirated software will be safe to use - also part of the culture.
You know what makes it even sadder? While propaganda does play a huge part of it, from all that we can gather information-wise, a vast majority is motivated by abject poverty and lack of perspectives in life instead of jingoist enthusiasm.
They have been beaten down and dehumanised by the system first, given a bleak and cynical outlook on life and themselves - and then basically been offered money for suicidal operations, most likely benefitting their relatives unless they manage to “win the lottery” and come back home alive.
There’s a very real risk this will become the future of recruitment in Western nations as well, so we really should not turn off our empathy, even though I will never understand how they can charge forward into pants-shitting terror like this, instead of either surrendering or downright fragging their commanders in open mutiny.
