This story tells us that cheaters make mistakes too, and that when they do that will be fatal for them.

This is not to encourage a scam.
Cheaters also make mistakes, but there are some mistakes made out of foolishness. An example is what the adolescents did after stealing BTC worth $243M all they can do is live a lavish lifestyle, spend huge funds in the club.
Although this issue happened last year but I have the privilege of watching the video of the club session of the scammer spending money on drinks and girls in the club
I didn't read the article but based on the summary, they were amateurs, which is why they slipped up and unfolded everything.For sure they are gonna be end up behind bars for a pretty long and this should serve as a lesson for whoever think that they can steal money and hide away from everything.
Not everyone can maintain the professionalism of the Lazarus Group.

I don't know about their professionalism level, but they are not that mature, and when people of 15-20 years have millions of bucks, only a few of them can contain themselves from living a lavish lifestyle.
For the Lazarus group, they are professionally trained for years, so we can't compare them.
