Venafi, a company that offers a range of solutions to help
financial services companies secure their cryptographic keys and
digital certificates, has uncovered over 100,000 URL hijacks with
valid TLS ( Transport Layer Security) certificates targeting major
retailers.
Venafi conducted an analysis of lookalike domains targeting 20
major retailers, as the festive season is around the corner. The
analysis resulted in the discovery of 109,045 typosquatted domains
of retailers from the United States, the United Kingdom, Australia,
Germany, and France. These use TLS certificates to appear more
genuine.
This is more than double from last year and of these only 20,000
certificates were issued for retail.
These URL hijackers targeted 20 dominant retailers from countries
like the United States, the United Kingdom, Australia, Germany, and
France. Of the 109,045, nearly 84,000 hijacked US domains with
50,000 copying countries major players. In the UK, Venafi could
trace 14,000 fake retail certificates. The typosquatted domains
were not limited to the UK and US, but Venafi also discovered 7,000
certificates for fake domains targeting retailers in Germany, 3,500
Australian retailers, and 1,500 targeting French retailers.
Jing Xie, a senior threat intelligence researcher at Venafi said,"
Some of these URLs probably serve a legitimate purpose, but many
may be used by attackers for fraudulent purposes. We think the
sheer volume of these sites is a strong indication that a large
number of them are being used for malicious purposes, especially
since we are so close to the holiday shopping season. " (Sc.

He also added, “Although our research did not analyze the specific
threats connected with these domains, we know that lookalike
domains are frequently used in phishing attacks and to distribute
malware. For example, back in 2017, security researchers found that
many certificates that contained the word ‘Paypal’ were used in
phishing websites. It’s logical to assume that attackers are using
similar tactics with other retail domains.”
60% of the total fake domains and 85% of lookalike domains
targeting German retailers got their TLS certificates from Let’s
Encrypt. Let's Encrypt Certificate Authority, is an online forum
which gives free certificates to website owners that they can use
to encrypt traffic, however, it seems miscreants are also taking
advantage of its services.
