Phish of GoDaddy Employee Jeopardized Escrow.com, Among Others

A spear-phishing attack this week hooked a customer service employee at GoDaddy.com, the world’s largest domain name registrar, KrebsOnSecurity has learned. The incident gave the phisher the ability to view and modify key customer records, access that was used to change domain settings for a half-dozen GoDaddy customers, including transaction brokering site escrow.com.

Escrow.com helps people safely broker all sorts of transactions online (ironically enough, brokering domain sales is a big part of its business). For about two hours starting around 5 p.m. PT Monday evening, Escrow.com’s website looked radically different: Its homepage was replaced with a crude message in plain text:

DomainInvesting.com’s Elliot Silver picked up on the change and got a statement from Matt Barrie, the CEO of freelancer.com, which owns escrow.com.

“During the incident, the hackers changed the DNS records for Escrow.com to point to to a third party web server,” Barrie wrote, noting that his security team managed to talk to the hacker responsible for the hijack via telephone.

Barrie said escrow.com would be sharing more details about the incident in the coming days, but he emphasized that no escrow.com systems were compromised, and no customer data, funds or domains were compromised.

KrebsOnSecurity reached out to Barrie and escrow.com with some follow-up questions, and immediately after that pinged Chris Ueland, CEO of SecurityTrails, a company that helps customers keep track of their digital assets.

Ueland said after hearing about the escrow.com hack Monday evening he pulled the domain name system (DNS) records for escrow.com and saw they were pointing to an Internet address in Malaysia — 111.90.149[.]49 (that address is hobbled here because it is currently flagged as hosting a phishing site). The attacker also obtained free encryption certificates for escrow.com from Let’s Encrypt.

Running a reverse DNS lookup on this 111.90.149[.]49 address shows it is tied to fewer than a dozen domains, including a 12-day-old domain that invokes the name of escrow.com’s registrar — servicenow-godaddy[.]com. Sure enough, loading that domain in a browser reveals the same text that appeared Monday night on escrow.com, minus the redaction above.

The message at servicenow-godaddy[.]com was identical to the one displayed by escrow.com while the site’s DNS records were hacked.

It was starting to look like someone had gotten phished. Then I heard back from Matt Barrie, who said it wasn’t anyone at escrow.com that got phished. Barrie said the hacker was able to read messages and notes left on escrow.com’s account at GoDaddy that only GoDaddy employees should have been able to see.

Barrie said one of those notes stated that certain key changes for escrow.com could only be made after calling a specific phone number and receiving verbal authorization. As it happened, the attacker went ahead and called that number, evidently assuming he was calling someone at GoDaddy.

In fact, the name and number belonged to escrow.com’s general manager, who played along for more than an hour talking to the attacker while recording the call and coaxing information out of him.

“This guy had access to the notes, and knew the number to call,” to make changes to the account, Barrie said. “He was literally reading off the tickets to the notes of the admin panel inside GoDaddy.”

In a statement shared with KrebsOnSecurity, GoDaddy acknowledged that on March 30 the company was alerted to a security incident involving a customer’s domain name. An investigation revealed a GoDaddy employee had fallen victim to a spear-phishing attack, and that five other customer accounts were “potentially” affected — although GoDaddy wouldn’t say which or how many domains those customer accounts may have with GoDaddy.
