Naoki Hiroshima, a San Francisco-based computer software engineer with
Lark Technologies, wrote a shocking blog post called “My $50,000 Twitter Username Was Stolen Thanks to PayPal and GoDaddy,” over at his blog on the Medium platform. I reprinted a summary of much of it here, with a link to the rest of it:

How I Lost My $50,000 Twitter Username
A story of how PayPal and GoDaddy allowed the attack and caused me to lose my $50,000 Twitter username.

My $50,000 Twitter Username Was Stolen Thanks to PayPal and GoDaddy
I had a rare Twitter username, @N. Yep, just one letter. I’ve been offered as much as $50,000 for it. People have tried to steal it. Password reset instructions are a regular sight in my email inbox. As of today, I no longer control @N. I was extorted into giving it up.

While eating lunch on January 20, 2014, I received a text message from PayPal for one-time validation code. Somebody was trying to steal my PayPal account. I ignored it and continued eating.

Later in the day, I checked my email which uses my personal domain name (registered with GoDaddy) through Google Apps. I found the last message I had received was from GoDaddy with the subject “Account Settings Change Confirmation.” There was a good reason why that was the last one.

Dear naoki hiroshima,
You are receiving this email because the Account Settings were modified for the following Customer Account:

There will be a brief period before this request takes effect.
If these modifications were made without your consent, please log in to your account and update your security settings.
If you are unable to log in to your account or if unauthorized changes have been made to domain names associated with the account, please contact our customer support team for assistance: [email protected] or (480) 505-8877.
Please note that Accounts are subject to our Universal Terms of Service.
Sincerely,
GoDaddy
I tried to log in to my GoDaddy account, but it didn’t work. I called GoDaddy and explained the situation. The representative asked me the last 6 digits of my credit card number as a method of verification. This didn’t work because the credit card information had already been changed by an attacker. In fact, all of my information had been changed. I had no way to prove I was the real owner of the domain name.

The GoDaddy representative suggested that I fill out a case report on GoDaddy’s website using my government identification. I did that and was told a response could take up to 48 hours. I expected that this would be sufficient to prove my identity and ownership of the account.

Let The Extortion Begin
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.

I soon realized, based on my previous experiences being attacked, that my coveted Twitter username was the target. Strangely, someone I don’t know sent me a Facebook message encouraging me to change my Twitter email address. I assumed this was sent from the attacker but I changed it regardless. The Twitter account email address was now one which the attacker could not access.

The attacker tried to reset my Twitter password several times and found he couldn’t receive any of the reset emails because it took time for the change of my domain’s MX record, which controls the email domain server. The attacker opened issue #16134409 at Twitter’s Zendesk support page.

N, Jan 20 01:43 PM:
Twitter username: @n
Your email: *****@*****.***
Last sign in: December
Mobile number (optional): n/a
Anything else? (optional): I’m not receiving the password reset to my email, do you think you could manually send me one?
Twitter required the attacker to provide more information to proceed and the attacker gave up on this route.

I later learned that the attacker had compromised my Facebook account in order to bargain with me. I was horrified to learn what had happened when friends began asking me about strange behavior on my Facebook account.

I received an email from my attacker at last. The attacker attempted to extort me with the following message.

Subject: Hello.
I’ve seen you spoke with an accomplice of mine, I would just like to inform you that you were correct, @N was the target. it appears extremely inactive, I would also like to inform you that your GoDaddy domains are in my possession, one fake purchase and they can be repossessed by godaddy and never seen again D:
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 5minutes while I swap the handle in exchange for your godaddy, and help securing your data?
Shortly thereafter, I received a response from GoDaddy.

Unfortunately, Domain Services will not be able to assist you with your change request as you are not the current registrant of the domain name. As the registrar we can only make this type of change after verifying the consent of the registrant. You may wish to pursue one or more of the following options should you decide
to pursue this matter further:
1. Visit http://who.godaddy.com/ to locate the Whois record for the domain name and resolve the issue with the registrant directly.
2. Go to http://www.icann.org/dndr/udrp/approved-providers.htm to find an ICANN approved arbitration provider.
3. Provide the following link to your legal counsel for information on submitting legal documents to GoDaddy: http://www.godaddy.com/agreements/showdoc.aspx?pageid=CIVIL_SUBPOENA GoDaddy now considers this matter closed.
My claim was refused because I am not the “current registrant.” GoDaddy asked the attacker if it was ok to change account information, while they didn’t bother asking me if it was ok when the attacker did it. I was infuriated that GoDaddy had put the burden on the true owner.

A coworker of mine was able to connect me to a GoDaddy executive. The executive attempted to get the security team involved, but nothing has happened. Perhaps because of the Martin Luther King Jr. holiday.

Then I received this follow-up from the attacker.

Are you going to swap the handle? the godaddy account is ready to go. Password changed and a neutral email is linked to it.
I asked a friend of mine at Twitter what the chances of recovering the Twitter account were if the attacker took ownership. I remembered what had happened to @mat and concluded that giving up the account right away would be the only way to avoid an irreversible disaster. So I told the attacker:

I released @N. Take it right away.
I changed my username @N to @N_is_stolen for the first time since I registered it in early 2007. Goodbye to my problematic username, for now.

I received this response.

Thank you very much, your godaddy password is: V;Mz,3{;!’g&
if you’d like I can go into detail about how I was able to gain access to your godaddy, and how you can secure yourself
The attacker quickly took control of the username and I regained access to my GoDaddy account.

PayPal and GoDaddy Facilitated The Attack
I asked the attacker how my GoDaddy account was compromised and received this response:

Subject: RE: …hello
– I called paypal and used some very simple engineering tactics to obtain the last four of your card (avoid this by calling paypal and asking the agent to add a note to your account to not release any details via phone)
– I called godaddy and told them I had lost the card but I remembered the last four, the agent then allowed me to try a range of numbers (00-09 in your case) I have not found a way to heighten godaddy account security, however if you’d like me to
recommend a more secure registrar i recommend: NameCheap or eNom (not network solutions but enom.com)
It’s hard to decide what’s more shocking, the fact that PayPal gave the attacker the last four digits of my credit card number over the phone, or that GoDaddy accepted it as verification. When asked about this, the attacker responded with this message:

Subject: RE: …hello
Yes paypal told me them over the phone (I was acting as an employee) and godaddy let me “guess” for the first two digits of the card
But guessing 2 digits correctly isn’t that easy, right?

I got it in the first call, most agents will just keep trying until they get it
He was lucky that he only had to guess two numbers and was able to do it in a single call. The thing is, GoDaddy allowed him to keep trying until he nailed it. Insane. Sounds like I was dealing with a wannabe Kevin Mitnick—it’s as though companies have yet to learn from Mitnick’s exploits circa 1995.

Here’s the total blog post: https://medium.com/p/24eb09e026dd

Naoki Hiroshima cautions against using a Google Apps email because he says the password has a chance of being stolen if the domain is compromised. But the bottom line is that PayPal had no business giving anyone his credit card information. The person who did that should be terminated, immediately.
