Thanks for posting this thread, El Loro. As some of you will know, I've been on holiday and without internet access, so there's little I could do about this until now.
A colleague informed me about haveibeenpwnd a while back and I was "clean" then, but it looks like this latest hack has finally caught me - so: new password time...
My lesser-used address is still clean, but I see my work email has finally been pwnd too - not that I'll be the only one there. Quite a few colleagues were caught in previous hacks, so I'll probably check a few other addresses, but wait till I'm back at work and able to see what action IT are taking before I escalate things (needless to say, company policy enforces 90-day password changes, and I'm due soon anyway).
