Computer forensics expert Craig Ball was recently hit with a Registration Bomb attack, and writes about it on his blog. I had never heard of this before, but it sounds like something that could be used against anyone:
they serve to mask attacks on legitimate accounts by burying notices of password resets, funds transfers or fraudulent credit card charges beneath a mountain of messages.
The good news is that, if you’re vigilant in the hours a registration bomb is exploding in your email account and you have MFA protecting your accounts, you’re in good shape.
Go check it out — it’s a short read, and Ball explains how to effectively protect yourself from this type of attack if you are ever on the receiving end.
