Well technically, they weren't hacked. They freely handed their info over, which was used to log in. No hacking here.

I've been saying from the start: The authenticator is not a replacement for common sense, a good firewall and some healthy caution.

It just makes those three even better.

As Boubouille wisely said:

" * Yes, you can get hacked even if you have an authenticator, the chances are MUCH lower but you're not invulnerable.
* It definitely isn't an excuse to not have an authenticator. We're talking about a single virus here and the authenticator will save your ass 99% of the time.
* Get a decent anti-virus, buy an authenticator, you'll be safe"

Also, Blizzard has never said their authenticator is the holy grail of account security.

No system will be infallible as long as humans are in the loop. I would think that Blizzard's network security guys would have known that already, and didn't realize that just now.

I could see blue/green posters responding unfavorably to a claim by someone about the account being hacked, but it may be due to how you phrase it.
"My authenticator got hacked" makes a very different statement from "My account with an authenticator attached was compromised". Then again, maybe the blue/green posters were being unreasonable ... they're humans too - see the first sentence I wrote again :P

@ROb - were these the same two guild mates who swore they where hacked and their toons where clearing out the bank and they SAID they had an authenticator but the blue confirmed that they actually lied and did not have authenticators attached to their accounts?
