This isn't a rumour and I don't share information unless I'm either personally trained on the topic or have learn that information from a reputable news source. This feature in question even included interviews with some individuals who have ran ransomware attacks.

The only reason I said "somewhere" in my original post was because I cannot remember which network it was published on.

Not a rumor. This is very common. For instance, an example from a marketplace advert.

TBF, in the sense that it's widely discussed, this particular rumor is already "real"

Its OK as long as gossip fit "progressive" agenda and/or comes from renowned "progressive" newspaper Pravda. Otherwise it is a racis' conspiracy.

That WaPo Krebs article links malware analysis which goes into dire detail on how that ransomware probes for Volume Shadow Copy (via amateur WMI) yet... omits keyboard layout probe method(s) at all (there are at least 3 possible ways)

Depends on the method. You're safe from Russian hackers/malware if you're OS has the Russian keyboard added.

It's even a security precaution.

Tldr: it's not hearsay
