It looks like Paypal has suffered a break-in and phishing attempts are
being made on its users.

Time to sell you stock (or buy it short) for the immediate future.

If that's true, I think the more interesting fact is: it appears
email-edg.paypal.com is controlled by the attacker. Why else would
Paypal redirect from a host in their domain to a host not in their
domain controlled by the adversary? (Its a bit different than standard
phishing training where both hosts/domains are controlled by Paypal).

Has Paypal fess'ed up to any break-ins or  breaches?
