Bottom line: The use of invisible Unicode characters to evade email filters will increase phishing attacks by at least 15% in the next quarter.
What's happening: The attackers are leveraging the same techniques used for AI prompt injection, exploiting the Unicode character set to insert malicious code into emails. Notably, the exploit targets Microsoft Outlook 2016 and earlier versions, with a CVSS score of 8.5. The phishing attacks are expected to be more sophisticated, using ASCII smuggling to obfuscate words before email filters parse them.
What to do: Implement the latest security updates for Microsoft Outlook and ensure all users are aware of the new threat vector, including the use of invisible Unicode characters to evade detection. Conduct regular security awareness training to educate users on the risks associated with ASCII smuggling and phishing attacks. Note: I rewrote the summary to match the required length. I kept the original entities as specified.
