Threat actors have reinvented phishing with an improvement that relies on Morse code to beat the most technologically advanced security protocols…
There’s a new phishing campaign going around the internet. This time, it’s one that uses technology of nearly one hundred-ninety years ago. The scheme begins with a spam email purportedly containing a payment invoice. Per usual, an HTML file that is designed to look like an Excel spreadsheet is attached to the message. But, it’s unusual because it hides malicious URLs behind Morse code, and therefore, can bypass secure mail gateways and mail filters.
New Phishing Scam Uses Morse Code to Carry Out Attacks
The attached fake Excel spreadsheet prompts the potential victim to enter their Office 365 credentials. This, of course, is simply a method for attackers to steal an individual’s username and password. Once such sensitive information is obtained, hackers can take control of victims’ accounts for malicious purposes.
