Input	Output
URL: PDF Model: gpt-4o	``` { "riskscore": 8, "reasons": "The PDF document appears to be a phishing attempt. It impersonates a well-known brand, McAfee, and includes a sense of urgency by confirming a high-value order ($523.86) that the recipient may not have made. This could prompt the recipient to contact the provided phone number, which is a common tactic in phishing scams. The document does not contain a visually prominent button or link, but the phone number is prominently displayed multiple times, encouraging the recipient to call for assistance. The sense of urgency is directly connected to the prominent phone number, increasing the likelihood that the recipient will act without verifying the legitimacy of the document." }
