This phishing attack uses some very retro technology to hide its payload

A new phishing attack has been discovered making use of a form of communication that is more commonly associated with 19th-century radio signals than modern cyberattacks: Morse code. The campaign uses Morse code to enable malicious login forms to escape detection by anti-phishing email software.  

As with many phishing campaigns, this one starts with a spam email purportedly containing a payment invoice. Attached to the email is an HTML file that is designed to look like an Excel spreadsheet. Typically, the file ends: “_xlsx.html.”
