It might be Russian hackers but the conspiracy theorist in me says it has something to do with mycrypto.com.
The lady who used to work with myetherwallet tried to hijack myetherwallet's customers and redirected them to her site (which is mycrypto.com). She essentially pulled the rug under the guy who came up with the idea originally and then proceeded to act like she's a victim. This just smells so much like her.
