Kaspersky Secure Mail Gateway has added a technology to read QR codes and check for phishing links hidden within them.Attackers use QR codes to bypass security measures and hide phishing links from scanners.QR codes are commonly scanned on personal devices without proper security software, making them more vulnerable to phishing attacks.Kaspersky's technology extracts links from QR codes in images and PDF files, checking them for phishing and flagging suspicious emails accordingly.
