Developer Loses Single-Letter Twitter Handle Through Extortion
Hugh Pickens DOT Com writes "Naoki Hiroshima, creator of Cocoyon and a developer for Echofon, writes at Medium that he had a rare one-letter Twitter username — @N — and had been offered as much as $50,000 for its purchase. 'People have tried to steal it. Password reset instructions are a regular sight in my email inbox,' writes Hiroshima. 'As of today, I no longer control @N. I was extorted into giving it up.' Hiroshima writes that a hacker used social engineering with Paypal to get the last four digits of his credit card number over the phone then used that information to gain control of his GoDaddy account. 'Most websites use email as a method of verification. If your email account is compromised, an attacker can easily reset your password on many other websites. By taking control of my domain name at GoDaddy, my attacker was able to control my email.' Hiroshima received a message from his extortionist. 'Your GoDaddy domains are in my possession, one fake purchase and they can be repossessed by godaddy and never seen again. I see you run quite a few nice websites so I have left those alone for now, all data on the sites has remained intact. Would you be willing to compromise? access to @N for about 5 minutes while I swap the handle in exchange for your godaddy, and help securing your data?' Hiroshima writes that it''s hard to decide what's more shocking, the fact that PayPal gave the attacker the last four digits of his credit card number over the phone, or that GoDaddy accepted it as verification. Hiroshima has two takeaways from his experience: Avoid custom domains for your login email address and don't let companies such as PayPal and GoDaddy store your credit card information."
like so many other articles, this just seems like another reminder to never ever use godaddy
the godaddy person let him keep trying various numbers until it worked. How can you trust them when it comes to security at all.
These companies need to be held accountable for their actions.
When the Target data breach happened, I commented here about some of the advantages to using throw-away, preload credit cards (which limits your potential loss and allows you to quickly switch to an entirely different account if you feel the other might be compromised). I was modded down by people who have bought into the whole big-bank credit card racket, and the attitude "why should I worry, when the bank is responsible and I'll eventually get my money back". Well here is yet another advantage of using preloaded credit cards. You load money on it, pay your annual hosting fees, etc, and then just toss it and get another next year to make the next annual payment. This story illustrates the advantages of using an entirely different credit card per service, so the card you use with Godaddy is not the same as you use with Paypal.
Yes, yes, it will cost you $3 each time you load a card to make that yearly payment, but you can decide for yourself what that extra $3 can buy you.

Why Paypal?
The last four digits of your credit card are printed on pretty much every receipt, shown on every order confirmation page, every "My account saved credit cards" screen, and are usually shown in addition to an expiration date. That's information that's never been considered confidential - quite the opposite indeed. It's pretty much public information.
GoDaddy was insane to consider it valid authentication information. You might just as well treat someone's name as their password.
You are not alone. This is not normal. None of this is normal.

Is that the current controller of N is legitimate, and *this* story is the social engineering attack to get control of it.

True, but irrelevant. Think about that for a minute -- you call PayPal and tell them:
"I have forgotten the last 4 digits of my credit card number, can you give them to me".
In what bizzaro parallel universe does that even make sense? There is no amount of "social engineering" that can explain why you need someone to tell you the last 4 digits of YOUR credit card.
PayPal needs to be reamed for such a major fuck up.
"I have forgotten the last 4 digits of my credit card number, can you give them to me".
"Hi, Paypal phone service person, I recently switched banks, and I think I might need to update my card info. I forget if I did this earlier --- can you tell me which card you've already got on file for me? Just the last four digits would be enough, thanks."

In an ideal universe: "Sir, if you tell me the last four digits of the card number, I can tell you if you updated it."

Right, in an ideal universe everyone would follow security-conscious procedures. In the real universe, the phone service rep is a minimum-wage worker in a foreign country, whose top priority is keeping down their time-per-call-resolution metric. Quickly helping a friendly, innocent, and clueless-sounding customer, versus remembering and strictly following every procedure in the 400-page employee handbook, doesn't always happen. That's why social engineering works --- the system is not designed for maximum security rigor, but for cutting corners on call-answering costs.
