Russian malware communicates by leaving comments in Britney Spears's Instagram

That's pretty ingenious. I've always thought the best way to communicate something like insider trading info would be on a stock board. Or if Trump wanted to communicate with Russians, it woudl be much less traceable than email. Email is one to one, a message board is many to many, hard to track down, and most messages are incomprehensible gibberish anyway, like this instagram message.

Note: The regex in this article is wrong. What the article currently lists:

  (?:\\u200d(?:#|@)(\\w)

But this is an invalid regex (parens aren't balanced), and it wouldn't work anyway. I believe the correct regex is

  (?:\\u200d|#|@)(\\w)
