I hate to say it... Oh, who am I kidding? I LOVE to say, "I told you so!" This is actually pretty neat, so long as you're not salesforce.com.
(Via Schneier) Salesforce.com admitted today that one of their employees was the victim of targeted phishing. And that once his account was compromised, it was used to get lists of e-mail addresses for... wait for it... more targeted phishing attacks!
So as targeted phishing attacks pass from the realm of pen-testers-who-can't-use-debuggers to actual criminals, the anti-spam/phishing segment is going to have to catch up. And it's not going to be easy, because traditionally collecting spam and phishing e-mails has been remarkably easy. But once the attacks become targeted, it's exponentially harder to get samples before the damage is done.
Enter the custom-tailored anti-phishing service. Gonna call those VC folks back.
