In IT Blogwatch, bloggers mutter, "Oh, ****."

Your humble blogwatcher curated these bloggy bits for your entertainment.

Eric Ravenscraft reports:

Bad news first, folks. LastPass, our favorite password manager (and yours) has been hacked.

And Christopher Boyd adds:

On the off-chance you reused your LastPass master password on another should alter all affected logins – password reuse is a major problem and not one to be taken lightly.

LastPass has a lot of additional security options in place and you should be making the most of them.  MORE

LastPass CEO Joe Siegrist 'fesses up:

Furthermore, if you are not already doing so you really should enable multi-factor authentication on your LastPass account. [But] don't panic. The sky is not falling.  MORE

But things are running slowly, as JD Jansen explains:

The danger in a password manager stored centrally on a server is not just the central point of attack, but, as we’re seeing now, when everyone tries to change their password no one can change their password.  MORE
