The first report was bullshit by some nobody to make money, nothing more and nothing less. This is more of the same bullshit to make bogeymen, and Russia has been a good target lately. I have worked in IT security for nearly 3 decades, so yes I do have some knowledge.
The 1.2 billion "credentials" was nothing to worry about (see disclaimer below), and still isn't. Hackers move massive lists of email addresses all the time, and try to run brute force attacks all the time. We block hundreds of thousands of these attacks every day. The majority are [email_addr@domain] with a password of 'password1'. Most of the time these are easy to see, as neither the user or domain exist on the targeted servers. Even the legit addresses are easy to detect, because hackers will use the top 25 worst passwords (just like you can find in articles every year, no I'm not kidding). Rarely do I ever see anything complex, like
If I was a conman and wanted to make fast cash, I could start dumping all of these email addresses to a DB, and say "Oh Noez! This email account is haxxored! When in reality, there is no such compromise. To fluff numbers, I hash 'password1' in SHA, MD5, CRYPT, and maybe even use plain text. 300 million accounts has now given me a claim of 1.2 billion 'credentials', and you can hopefully see that the claim is complete shit! I can gather that 300 million addresses in a week without breaking a sweat.
Disclaimer. You should be changing passwords for anything you care about frequently. 8 character passwords every 90 days, 14-16 character every 6 months. If you are using a strong password and are up for a change, go do so, no big deal. Since I write this shit for policies regularly, a "strong" password consists of the following.
1. No dictionary words, proper names or common acronyms in forward or reverse.
2. No QWERTY keys, including qazwsx, 54321, etc...
3. Contains at least 1 special character, 1 number, 1 upper and 1 lower case character.
4. Is not 'p@SSw0rd' or some other l337 speak that would be in a cracklib dictionary, and there is plenty there.
There are obviously restrictions in some places, so if you can't use certain characters make a longer password. If you can't make a longer password change the password more frequently. The majority of 'hackers' are script kiddies, not hackers. If you make things hard, they find a different target. There are numerous people out there that use 'password1' for their password, don't be one of them.
