- Redirect to Malicious Content: Upon scanning, the victim is redirected to a fraudulent website or landing page that masquerades as a legitimate one. This may include fake login portals, phishing forms, or sites designed to distribute malware.
- Data Harvesting: Once on the malicious site, unsuspecting victims may unwittingly give out sensitive information, such as login credentials or personal details, which are then harvested by cybercriminals for malicious purposes.
