Quote:The phishing campaign is using a new technique to hide the source code of its landing page – and stealing credentials from customers of a major U.S.-based bank.

An insidious phishing method evades detection using a never-before-seen technique that leverages custom fonts to cover its tracks.

Researchers at Proofpoint recently discovered an active credential harvesting phishing scheme. Once a victim has clicked on the initial phishing email, the resulting landing page looks like a login page for a major U.S. bank – but in reality the page is bent on stealing banking customers’ credentials, Chris Dawson, threat intelligence lead at Proofpoint, told Threatpost. The phishing kit uses custom web fonts to obfuscate the source code for the landing page – making it seem harmless.

“While encoded source code and various obfuscation mechanisms have been well documented in phishing kits, this technique appears to be unique for the time being in its use of web fonts to implement the encoding,” researchers at Proofpoint said in a Thursday analysis of the technique.
