The QR code you just scanned may have led you to a malicious link. This page could attempt to run scripts, request permissions, auto-download files, or trick you into entering sensitive information (such as passwords, one-time codes, or bank details). This is a social engineering attack example — attackers exploit curiosity or trust to gain access and make you a victim.
A QR code is just an encoded URL. Once your phone or browser opens the link, the site may attempt to execute JavaScript, request camera/location/notification access, show fake forms, or prompt downloads. Attackers often disguise these links as event pages, coupons, or visitor logs to make you click without thinking.
Attackers exploit human psychology: curiosity, urgency, trust in authority, or fear of missing out. For example, “Claim your free reward now” or “Verify your delivery info” tricks users into quick, unverified actions that expose sensitive data.
Impersonation / Pretexting — Pretending to be IT support, suppliers, or managers to request access.
Phishing — Fake emails or web pages tricking you into clicking links or sharing credentials.
Vishing — Voice phishing over phone calls to extract sensitive information.
Baiting — Luring victims with infected USB drives or free software downloads.
Tailgating — Following authorized personnel into restricted areas without permission.
OSINT Abuse — Collecting info from public sources (social media, job postings) to design targeted attacks.
Conclusion
The essence of social engineering is exploiting human nature. The key defense is to make “suspicion and verification” a routine, and protective measures a habit.
