By the way, ‘lapsus’ as a slang-ish Russian word was around perhaps until 1970s or 1980s. Quite rare today. Means ‘a dumb mistake’. It comes from Latin, and Wiktionary says that it's used in English and Romance-family languages, but I've never seen it outside of Russian. It might be used in other Slavic languages, though. If the word is not around in Western languages, then presumably it would point to Russian origins, or someone really did their homework to misattribute blame. (Or I might've missed the news where those guys are already uncovered—so far I only saw it being mentioned that the attack is from South America.)
