Phishing Delivery: A phishing email impersonates a formal Request for Proposal (RFP), inviting the target to bid on a project. The email includes a preview link labeled as a PDF attachment, which leads to a Box-themed decoy page, eventually redirecting to a fake Microsoft login page for credential harvesting.

What is the attack?
Why did it get through?

URL Crawling/Analysis Protection: The added Captcha functionality limits automated link crawling and URL analysis features, increasing the difficulty for automated detection.
