Cybersecurity researchers today highlighted an evasive phishing technique that attackers are exploiting in the wild to target visitors of several sites with a quirk in domain names, and leverage modified favicons to inject e-skimmers and steal payment card information covertly. "The idea is simple and consists of using characters that look the same in order to dupe users," Malwarebytes researchers said in a Thursday analysis . "Sometimes the characters are from a different language set or simply capitalizing the letter 'i' to make it appear like a lowercase 'l'." Called an internationalized domain name (IDN) homograph attack , the technique has been used by a Magecart group on multiple domains to load the popular Inter skimming kit hidden inside a favicon file . The visual trickery typically involves leveraging the similarities of character scripts to create and register fraudulent domains of existing ones to deceive unsuspecting users into
