Detect Possible Domain Spoofing and Homograph Attacks with Typosquatting Data Feed

Charles Caleb Colton once said that imitation was the sincerest form of flattery. This proverbial expression finds its origins in the 19th century and other historical writings before that. What likely wasn’t foreseen at the time, however, was that certain forms of imitation in the 21st century could give organizations terrible headaches. We are talking about domain spoofing and homograph attacks.

Imitators in our contemporary context can register one or several domain names highly similar to that of an established brand and use these to deceive people and trick them into sharing sensitive information or even transfering funds to fraudulent bank accounts.

Registering copycat domain names of known brands and organizations isn’t the only way to fool victims, though. At the height of coronavirus-themed attacks, the Typosquatting Data Feed proved useful in spotting potentially dangerous footprints containing thousands of domain names with word strings such as “covid” and “coronavirus” combined with “mask,” “vaccine,” “donation,” “lawsuit,” and plenty of others.

In this post, we put the feed’s capabilities to the test to detect spoofed domain names, including Punycode domains, that could be used to abuse employees, customers, and other parties who regularly interact with Lloyds Bank and Apple. We will also show how other sources of intelligence can help learn more about possible impersonators and the infrastructure they use.

Early Typosquatting Detection Made Possible: A Short Illustration in the Financial Sector

To those who keep an eye on trends in IT security threats, notably phishing and typosquatting attacks, the name Wells Fargo is not unfamiliar, not even to those who have no business relation whatsoever with this multinational financial services company. In fact, all financial companies are likely targets for phishing campaigns, and Wells Fargo had TCPA settlement cases which are amongst the greatest attractors of these kinds of threats. So, rather unsurprisingly, there has been a continuous and significant malicious activity against this company.

The footprint of coronavirus disease in domain name registrations

Cybercriminals use all possibilities which can serve their evil aims. They follow the headlines and react quickly – and they do not have ethical considerations. Even the drama of the coronavirus terrorizing the entire world and causing the deaths of thousands of people is seen as a good ’business’ opportunity to spread out some malware.

IBM X-force recently reported that the coronavirus went cyber via the Emotet trojan. Rather disgustingly, the miscreants send e-mails to people on behalf of respected health organizations, containing attachments claiming to inform about infection prevention measures. As the victim opens the attachment, it silently installs the trojan on the computer.

Traditional phishers are also on board, a typical case is described by Kaspersky: a coronavirus-related message containing a link to an Outlook-looking page to collect login credentials. All this has attracted a lot of media attention, of course...

TCPA settlements in the crosshairs of typosquatters

The Telephone Consumer Protection Act of 1991 (TCPA), Public Law 102-243., as also explained on its Wikipedia page, "restricts telephone solicitations (i.e., telemarketing & BPO) and the use of automated telephone equipment. The TCPA limits the use of automatic dialing systems, artificial or pre-recorded voice messages, SMS text messages, and fax machines."

Naturally, it has generated a number of court cases, which frequently result in calls for settlement claims. Victims can submit their claim online, either directly, or with the help of a number of lawyers and their companies specializing in helping with such cases. The related web pages attract a lot of visitors, and many of them type in the URL of the case manually - a very attractive situation to do some typosquatting… leaving a footprint of TCPA settlements in the records of WhoisXML API's Typosquatting Data Feed.

Typosquatting Daily Data Feed: the new enabler in the fight against phishing and malware

One result of our reseach and development is the introduction of the new "typosquatting data feed", an innovative data set based on our long-standing experience with cybersecurity and the Domain Name System. In what follows we will demonstrate how this new resource can be used efficiently in the fight against spam, phishing and malware.

The main idea behind the new data feed is the observation that domain names which were registered on the same day and have similar names have an increased likelihood of being involved in a range of IT scams, including typosquatting attacks, domain name hijacking, and also phishing and malware. So, we have developed a technology for finding these groups of domain names.
