Re LinkedIn. Yes, it was hacked today. I have found my password in the published list.
You can still download the hashes here: https://disk.yandex.net/disk/public/?hash=pCAcIfV7wxXCL%2FYPhObEEH5u5PKPlp%2BmuGtgOEptAS4%3D
Then you need to hash your password with sha1:

http://sha1-hash-online.waraxe.us/
… or similar tool…
If the hash is in the file above without 0000, you better change it. If your hash is marked with 0000 – they know your password already 😉
You better change it anyway.
