Episode 30 — Image and Attachment Attacks: QR Codes, CAPTCHA Abuse, Macros, PDFs, and RTF (2.3)
This episode explains how attackers use familiar images and file types to deliver malicious content or manipulate user trust. QR-code attacks can move users from a protected screen to a malicious site on a personal device. CAPTCHA abuse may make a fraudulent page look more legitimate or delay automated analysis. Macros, PDFs, and RTF documents can contain embedded content, scripts, links, or exploit paths that lead to compromise. For Security+ preparation, students should recognize that attachments are not safe just because they look routine, and that controls such as sandboxing, content filtering, user training, disabling macros, and endpoint protection reduce risk.
