One the comments on Emergent Chaos about my post Incentive plan for an information security team was from Andrew Jaquith of the Yankee Group:

dhs-predicts-more-brokerage-attacks

The DHS is joining in on one of my earlier predictions: Brokerage accounts will be increasing targeted in the coming year. According to their post they are tempting accounts because they typically have more money in them. Further, typical anti-fraud transaction analysis doesn't really work because of the infrequency of transfers.

I'm convinced that brokerage accounts and other heavy transactions accounts will need cryptographically secure transaction authentication in addition to session and host/mutual authentication.

Kudos to ETrade for offering a "zero liability" account. I suspect this is an attempt to foil my prediction that brokerage accounts will be increasingly targeted by phishers. (Though, to be honest, they were getting off to a good start in Q4.)

Brokerage accounts are tempting. Most people (if they have brokerage accounts) have more in their stock accounts than in their bank account or savings.

With brokerage accounts, phishers aim for bigger dollars. From the BusinessWeek article:

The SEC has noticed a dramatic rise in fraud against online brokerage accounts. This is a very interesting article in that it shows how an attacker can take over accounts and make money without necessarily removing money from those accounts. All they need is a couple of "legitimate" account that the fraudsters open, a thinly traded small-cap stock and to control a couple of pwned accounts with enough money to manipulate the targeted stock. The article describes "pumping" as using pwned accounts to drive up the price of stocks that you hold. However, you can also make money on the way down:
