PayPal’s Poor Security

Brian Krebs (via @SwiftOnSecurity):

My PayPal account was hacked on Christmas Eve. The perpetrator tried to further stir up trouble by sending my PayPal funds to a hacker gang tied to the jihadist militant group ISIS. Although the intruder failed to siphon any funds, the successful takeover of the account speaks volumes about why most organizations — including many financial institutions — remain woefully behind the times in authenticating their customers and staying ahead of identity thieves.

But by the time I got back home to a computer, my email address had been removed and my password had been changed. So much for PayPal’s supposed “monitoring;” the company couldn’t even spot the same fraudulent email address when it was added a second time.

[…]

In my second call to PayPal, I insisted on speaking with a supervisor. That person was able to tell me that, as I suspected, my (very long and complex) password was never really compromised. The attacker had merely called in to PayPal’s customer support, pretended to be me and was able to reset my password by providing nothing more than the last four digits of my Social Security number and the last four numbers of an old credit card account.

[…]

PayPal does offer additional security protections — including a PayPal Security Key fob that periodically generates a new one-time password which needs to be entered at login in addition to a username and password. I’ve used this solution since shortly after the company began offering it almost a decade ago, but a fat lot of good it does if PayPal is going to continue letting users reset their passwords by regurgitating static data that is trivial to purchase from the cybercrime underground.

Dave Mark:

Last night we got an email from a PayPal spokesperson with this official response:

The safety and security of our customers’ accounts, data and money is PayPal’s highest priority. Due to our privacy policies that protect our customers, PayPal does not publicly disclose details about our customers’ accounts or their specific cases. However, it appears that our standard procedures were not followed in this case. While the funds remained secure, we are sorry that this unacceptable situation arose and we are reviewing the matter in order to prevent it from happening again.
