AiTM - QR Code Image Extraction (T1566)
Detects emails containing embedded PNG, SVG, or JPG images (often QR codes) that are used in conjunction with a subject line indicating 'Code of Conduct' to bypass text-based URL filters and redirect users to an AiTM (Adversary-in-the-Middle) proxy. This technique is commonly used in phishing campaigns to steal authentication tokens.
