Apparently the worst mistake was contacting his former girlfriend in Russia:

>Exactly how the killers found him has not been established, though two senior Ukrainian officials said he had reached out to a former girlfriend, still in Russia, and invited her to come see him in Spain.

>“This was a grave mistake,” one of the officials said.

Or there's a mole in Ukrainian intelligence who sold him out

Questionable opsec is almost always the culprit. Even all these online black markets, it wasn’t some sophisticated operation to catch them. Many times, they use the same username on another website and now there’s a link. Hell, one of them used to send email verification for their black market using their personal email.

It doesn’t just stop there. A 49ers wide receiver got shot a couple weeks back because he posted on Instagram about buying a Rolex and he was lucky to survive. That’s also questionable opsec.

What is a "49ers wide receiver" ??

Please don't use google.

Also, yeah, this came up when I searched (on duckduckgo), but it seemed like the wrong match, since I don't see how it could be related ??

haha got it from ddg gi! ;)

and yes, it's unrelated for sure
