A message pretending to be your bank, a courier or your boss. The giveaway is urgency plus a link — act now, before you think to check who really sent it.
The drawing that proves the sentence above. It is the same card that is in the book.
Think of it as
a stranger in a courier's uniform asking for your keys.
For example
A text says your package is stuck and you must pay a small fee now. There is no package. Someone wants your card number, and the word "now" is the trick.
This is one card out of 275.
The hundred words you meet most are free — the whole set, animated, in one file that works with no internet.
Volume 1 has all 275 in fifteen chapters, with Staying Safe the largest chapter on purpose.
