CORE DEFINITION

Hackers do not directly crack your password, but rather collect your account credentials leaked on website A and attempt to log in to websites B and C. This is because most people use the same password for everything.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Risk transmission. Your security weakness is not in the place you protect most strictly, but in the account you least care about and consider least important. Similarly, in personal reputation management: your dishonesty in small matters (leaks) can be 'credential stuffed' to attack your important matters.

anchor

Anchor fast decisions

Exploiting 'password reuse': hackers use credentials leaked from site A to batch attempt logins on sites B and C. Because most people use the same password universally, the hit rate is high. Risk transmits from the weakest account to important accounts—your overall security depends on the account you least care about.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Use unique strong passwords/password manager for each site. 2. Enable multi-factor authentication. 3. Monitor credential leaks and change passwords. 4. In reputation management, do not be dishonest in small matters (to prevent transmission).
