In November 2020, KrebsOnSecurity heard from security researcher Abraham Vegh, who noticed something odd while inspecting an email from his financial institution.
Vegh could see the message from his bank referenced a curious domain: defaultinstitution.com. A quick search of WHOIS registration records showed the domain was unregistered. Wondering whether he might receive email communications to that address if he registered the domain, Vegh snapped it up for a few dollars, set up a catch-all email account for it, and waited.
“It appears that the domain is provided as a default, and customer bank IT departments are either assuming they don’t need to change it, or are not aware that they could/should,” Vegh said, noting that a malicious person who stumbled on his discovery earlier could have had a powerful, trusted domain from which to launch email phishing attacks.
