How scammers use your data to create personalized tricks that work

Think of your digital footprint as your online shadow, revealing a public portrait of your interests, connections, and routine that scammers can exploit. The piece explains your active footprint includes everything you choose to share—photos, reviews, and status updates—while the passive footprint collects data you don’t intend to expose, from cookies to GPS tags.

Real-world examples include AI voice scams that imitate a family member after a few seconds of audio, and a Facebook photo that can reveal where you live or spend time through background clues.

The piece concludes with practical safeguards like tightening privacy, using MFA, monitoring your data footprint, and staying sceptical of surprising messages.
