Increase in Email Threats Using Hidden Text Salting

/ 1 min read

🕵️‍♂️✨ Increase in Email Threats Utilizing Hidden Text Salting Techniques. Cisco Talos reported a rise in email threats employing hidden text salting, a method that allows malicious actors to bypass email parsers and evade spam filters by embedding invisible characters in the HTML source of emails. This technique confuses detection systems that rely on keyword recognition, making it easier for phishing attempts to succeed. Talos noted that hidden text salting is used for various purposes, including evading brand name extraction and complicating language detection. The simplicity and versatility of this approach pose significant challenges for email security measures, highlighting the need for enhanced detection capabilities to combat these evolving threats.
