U.S. Govt. Makes it Harder to Get .Gov Domains

The federal agency in charge of issuing .gov domain names is enacting new requirements for validating the identity of people requesting them. The additional measures come less than four months after KrebsOnSecurity published research suggesting it was relatively easy for just about anyone to get their very own .gov domain.

In November’s piece It’s Way Too Easy to Get a .gov Domain Name, an anonymous source detailed how he obtained one by impersonating an official at a small town in Rhode Island that didn’t already have its own .gov.

“I had to [fill out] ‘an official authorization form,’ which basically just lists your admin, tech guy, and billing guy,” the source said. “Also, it needs to be printed on ‘official letterhead,’ which of course can be easily forged just by Googling a document from said municipality. Then you either mail or fax it in. After that, they send account creation links to all the contacts.”

While what my source did was technically wire fraud (obtaining something of value via the Internet through false pretenses), cybercriminals bent on using fake .gov domains to hoodwink Americans likely would not be deterred by such concerns.

“I never said it was legal, just that it was easy,” the source told KrebsOnSecurity. “I assumed there would be at least ID verification. The deepest research I needed to do was Yellow Pages records.”

Now, Uncle Sam says in a few days all new .gov domain applications will include an additional authorization step.

“Effective on March 10, 2020, the DotGov Program will begin requiring notarized signatures on all authorization letters when submitting a request for a new .gov domain,” reads a notice published March 5 by the U.S. General Services Administration, which oversees the .gov space.

“This is a necessary security enhancement to prevent mail and wire fraud through signature forgery in obtaining a .gov domain,” the statement continues. “This step will help maintain the integrity of .gov and ensure that .gov domains continue to be issued only to official U.S. government organizations.” Continue reading →

A Tough Week for IP Address Scammers

In the early days of the Internet, there was a period when Internet Protocol version 4 (IPv4) addresses (e.g. 4.4.4.4) were given out like cotton candy to anyone who asked. But these days companies are queuing up to obtain new IP space from the various regional registries that periodically dole out the prized digits. With the value of a single IP hovering between $15-$25, those registries are now fighting a wave of shady brokers who specialize in securing new IP address blocks under false pretenses and then reselling to spammers. Here’s the story of one broker who fought back in the courts, and lost spectacularly.

On May 14, South Carolina U.S. Attorney Sherri Lydon filed criminal wire fraud charges against Amir Golestan, alleging he and his Charleston, S.C. based company Micfo LLC orchestrated an elaborate network of phony companies and aliases to secure more than 735,000 IPs from the American Registry for Internet Numbers (ARIN), a nonprofit which oversees IP addresses assigned to entities in the U.S., Canada, and parts of the Caribbean.

Interestingly, Micfo itself set this process in motion late last year when it sued ARIN. In December 2018, Micfo’s attorneys asked a federal court in Virginia to issue a temporary restraining order against ARIN, which had already told the company about its discovery of the phony front companies and was threatening to revoke some 735,000 IP addresses. That is, unless Micfo agreed to provide more information about its operations and customers.

At the time, many of the IP address blocks assigned to Micfo had been freshly resold to spammers. Micfo ultimately declined to provide ARIN the requested information, and as a result the court denied Micfo’s request (the transcript of that hearing is instructive and amusing).

But by virtue of the contract Micfo signed with ARIN, any further dispute had to be settled via arbitration. On May 13, that arbitration panel ordered Micfo to pay $350,000 for ARIN’s legal fees and to cough up any of those 735,000 IPs the company hadn’t already sold.

According to the criminal indictment in South Carolina, in 2017 and 2018 Golestan sold IP addresses using a third party broker:

“Golestan sold 65,536 IPv4 addresses for $13 each, for a total of $851,896,” the indictment alleges. “Golestan also organized a second transaction for another 65,536 IP addresses, for another approximately $1 million. During this same time period, Golestan had a contract to sell 327,680 IP addresses at $19 per address, for a total of $6.22 million” [this last transaction would be blocked.] Continue reading →
