Feds Take Down 13 More DDoS-for-Hire Services

The U.S. Federal Bureau of Investigation (FBI) this week seized 13 domain names connected to “booter” services that let paying customers launch crippling distributed denial-of-service (DDoS) attacks. Ten of the domains are reincarnations of DDoS-for-hire services the FBI seized in December 2022, when it charged six U.S. men with computer crimes for allegedly operating booters.

Booter services are advertised through a variety of methods, including Dark Web forums, chat platforms and even youtube.com. They accept payment via PayPal, Google Wallet, and/or cryptocurrencies, and subscriptions can range in price from just a few dollars to several hundred per month. The services are generally priced according to the volume of traffic to be hurled at the target, the duration of each attack, and the number of concurrent attacks allowed.

The websites that saw their homepages replaced with seizure notices from the FBI this week include booter services like cyberstress[.]org and exoticbooter[.]com, which the feds say were used to launch millions of attacks against millions of victims.

“School districts, universities, financial institutions and government websites are among the victims who have been targeted in attacks launched by booter services,” federal prosecutors in Los Angeles said in a statement.

Purveyors of booters or “stressers” claim they are not responsible for how customers use their services, and that they aren’t breaking the law because — like most security tools — these services can be used for good or bad purposes. Most booter sites employ wordy “terms of use” agreements that require customers to agree they will only stress-test their own networks — and that they won’t use the service to attack others.

But the DOJ says these disclaimers usually ignore the fact that most booter services are heavily reliant on constantly scanning the Internet to commandeer misconfigured devices that are critical for maximizing the size and impact of DDoS attacks. What’s more, none of the services seized by the government required users to demonstrate that they own the Internet addresses being stress-tested, something a legitimate testing service would insist upon.

This is the third in a series of U.S. and international law enforcement actions targeting booter services. In December 2022, the feds seized four-dozen booter domains and charged six U.S. men with computer crimes related to their alleged ownership of the popular DDoS-for-hire services. In December 2018, the feds targeted 15 booter sites, and three booter store defendants who later pleaded guilty.

While the FBI’s repeated seizing of booter domains may seem like an endless game of virtual Whac-a-Mole, continuously taking these services offline imposes high enough costs for the operators that some of them will quit the business altogether, says Richard Clayton, director of Cambridge University’s Cybercrime Centre.

In 2020, Clayton and others published “Cybercrime is Mostly Boring,” an academic study on the quality and types of work needed to build, maintain and defend illicit enterprises that make up a large portion of the cybercrime-as-a-service market. The study found that operating a booter service effectively requires a mind-numbing amount of constant, tedious work that tends to produce high burnout rates for booter service operators — even when the service is operating efficiently and profitably.

For example, running an effective booter service requires a substantial amount of administrative work and maintenance, much of which involves constantly scanning for, commandeering and managing large collections of remote systems that can be used to amplify online attacks, Clayton said. On top of that, building brand recognition and customer loyalty takes time.

“If you’re running a booter and someone keeps taking your domain or hosting away, you have to then go through doing the same boring work all over again,” Clayton told KrebsOnSecurity. “One of the guys the FBI arrested in December [2022] spent six months moaning that he lost his servers, and could people please lend him some money to get it started again.”

In a statement released Wednesday, prosecutors in Los Angeles said four of the six men charged last year for running booter services have since pleaded guilty. However, at least one of the defendants from the 2022 booter bust-up — John M. Dobbs, 32, of Honolulu, HI — has pleaded not guilty and is signaling he intends to take his case to trial.

The FBI seizure notice that replaced the homepages of several booter services this week.

Dobbs is a computer science graduate student who for the past decade openly ran IPStresser[.]com, a popular and powerful attack-for-hire service that he registered with the state of Hawaii using his real name and address. Likewise, the domain was registered in Dobbs’s name and hometown in Pennsylvania. Prosecutors say Dobbs’ service attracted more than two million registered users, and was responsible for launching a staggering 30 million distinct DDoS attacks.

Many accused stresser site operators have pleaded guilty over the years after being hit with federal criminal charges. But the government’s core claim — that operating a booter site is a violation of U.S. computer crime laws — wasn’t properly tested in the courts until September 2021.

That was when a jury handed down a guilty verdict against Matthew Gatrel, a then 32-year-old St. Charles, Ill. man charged in the government’s first 2018 mass booter bust-up. Despite admitting to FBI agents that he ran two booter services (and turning over plenty of incriminating evidence in the process), Gatrel opted to take his case to trial, defended the entire time by court-appointed attorneys.

Gatrel was convicted on all three charges of violating the Computer Fraud and Abuse Act, including conspiracy to commit unauthorized impairment of a protected computer, conspiracy to commit wire fraud, and unauthorized impairment of a protected computer. He was sentenced to two years in prison.

–Jeremiah Sam Evans Miller, aka “John The Dev,” 23, of San Antonio, Texas, who pleaded guilty on April 6 to conspiracy and violating the computer fraud and abuse act related to the operation of a booter service named RoyalStresser[.]com (formerly known as Supremesecurityteam[.]com);

–Angel Manuel Colon Jr., aka “Anonghost720” and “Anonghost1337,” 37, of Belleview, Florida, who pleaded guilty on February 13 to conspiracy and violating the computer fraud and abuse act related to the operation of a booter service named SecurityTeam[.]io;

–Shamar Shattock, 19, of Margate, Florida, who pleaded guilty on March 22 to conspiracy to violate the computer fraud and abuse act related to the operation of a booter service known as Astrostress[.]com;

–Cory Anthony Palmer, 23, of Lauderhill, Florida, who pleaded guilty on February 16 to conspiracy to violate the computer fraud and abuse act related to the operation of a booter service known as Booter[.]sx.

All four defendants are scheduled to be sentenced this summer.

Senators Urge FTC to Probe ID.me Over Selfie Data

Some of more tech-savvy Democrats in the U.S. Senate are asking the Federal Trade Commission (FTC) to investigate identity-proofing company ID.me for “deceptive statements” the company and its founder allegedly made over how they handle facial recognition data collected on behalf of the Internal Revenue Service, which until recently required anyone seeking a new IRS account online to provide a live video selfie to ID.me.

In a letter to FTC Chair Lina Khan, the Senators charge that ID.me’s CEO Blake Hall has offered conflicting statements about how his company uses the facial scan data it collects on behalf of the federal government and many states that use the ID proofing technology to screen applicants for unemployment insurance.

The lawmakers say that in public statements and blog posts, ID.me has frequently emphasized the difference between two types of facial recognition: One-to-one, and one-to-many. In the one-to-one approach, a live video selfie is compared to the image on a driver’s license, for example. One-to-many facial recognition involves comparing a face against a database of other faces to find any potential matches.

Americans have particular reason to be concerned about the difference between these two types of facial recognition, says the letter to the FTC, signed by Sens. Cory Booker (D-N.J.), Edward Markey (D-Mass.), Alex Padilla (D-Calif.), and Ron Wyden (D-Ore.):

“While one-to-one recognition involves a one-time comparison of two images in order to confirm an applicant’s identity, the use of one-to-many recognition means that millions of innocent people will have their photographs endlessly queried as part of a digital ‘line up.’ Not only does this violate individuals’ privacy, but the inevitable false matches associated with one-to-many recognition can result in applicants being wrongly denied desperately-needed services for weeks or even months as they try to get their case reviewed.”

“This risk is especially acute for people of color: NIST’s Facial Recognition Vendor Test found that many facial recognition algorithms have rates of false matches that are as much as 100 times higher for individuals from countries in West Africa, East Africa and East Asia than for individuals from Eastern European countries. This means Black and Asian Americans could be disproportionately likely to be denied benefits due to a false match in a one-to-many facial recognition system.”

The lawmakers say that throughout the latter half of 2021, ID.me published statements and blog posts stating it did not use one-to-many facial recognition and that the approach was “problematic” and “tied to surveillance operations.” But several days after a Jan. 16, 2022 post here about the IRS’s new facial ID requirement went viral and prompted a public backlash, Hall acknowledged in a LinkedIn posting that ID.me does use one-to-many facial recognition.

“Within days, the company edited the numerous blog posts and white papers on its website that previously stated the company did not use one-to-many to reflect the truth,” the letter alleges. “According to media reports, the company’s decision to correct its prior misleading statements came after mounting internal pressure from its employees.”

Cyberscoop’s Tonya Riley published excerpts from internal ID.me employee Slack messages wherein some expressed dread and unease with the company’s equivocation on its use of one-to-many facial recognition.

In February, the IRS announced it would no longer require facial scans or other biometric data from taxpayers seeking to create an account at the agency’s website. The agency also pledged that any biometric data shared with ID.me would be permanently deleted.

But the IRS still requires new account applicants to sign up with either ID.me or Login.gov, a single sign-on solution already used to access 200 websites run by 28 federal agencies. It also still offers the option of providing a live selfie for verification purposes, although the IRS says this data will be deleted automatically.

Asked to respond to concerns raised in the letter from Senate lawmakers, ID.me instead touted its successes in stopping fraud.

“Five state workforce agencies have publicly credited ID.me with helping to prevent $238 billion dollars in fraud,” the statement reads. “Conditions were so bad during the pandemic that the deputy assistant director of the FBI called the fraud ‘an economic attack on the United States.’ ID.me played a critical role in stopping that attack in more than 20 states where the service was rapidly adopted for its equally important ability to increase equity and verify individuals left behind by traditional options. We look forward to cooperating with all relevant government bodies to clear up any misunderstandings.”

As Cyberscoop reported on Apr. 14, the House Oversight and Reform Committee last month began an investigation into ID.me’s practices, with committee chairwoman Carolyn Maloney (D-N.Y.) saying the committee’s questions to the company would help shape policy on how the government wields facial recognition technology.
