What is PII - Personally Identifiable Information?

Personally identifiable information (PII) represents information about a person that can identify them, such as date of birth, social security number, credit card numbers and street address. 

 

PII is one of the most commonly stolen types of data in cyberattacks because it has monetary value in underground markets. Cybercriminals can use the data for financial gain through tactics such as identity theft (eg., filing fraudulent income tax returns, or applying for credit under the victim's name).
