Personally Identifiable Information (PII)
Posted on July 6, 2020 by in Identity & Privacy, Personal

You may see the acronym PII used when talking about security, privacy, and data breaches. PII stands for Personally Identifiable Information, the personal data that can be used to identify a specific individual. PII is usually sensitive and private information, such as your Social Security number, bank account number, driver’s license number, physical address, even your full name and your date of birth. The list is not exhaustive. It also includes medical, educational, financial, employment, and any other information that can be used to identify you by itself or when combined with other information.

If you’ve been keeping eye on the news surrounding identity theft, data breaches, personal or online privacy, you have probably noticed Personally Identifiable Information is often referenced. While this term might seem straightforward, it’s more complicated than you think. And, having your PII compromised by scammers can be devastating to your personal and financial profile.

The National Institute of Standards and Technology (NIST) defines PII as information which can be used to distinguish or trace the identity of an individual directly or can be combined with other personal or identifying information which is linkable to a specific individual (e.g., date and place of birth, mother’s maiden name, etc.). That is, when two or more pieces of information are connected, they point to a single person.

PII is significant because, whether lost, stolen, or exposed, it is how identity thieves perpetrate their crimes. Sometimes all it takes is one or two pieces of information to compromise a person’s identity. Still, not all PII is considered equal.

What Information is Considered PII?

Some pieces of information are unique to you, and you alone. PII in this context is often referred to as “sensitive.” These are the identifiers that identity thieves are most interested in capturing, and include your:

  • Personal identification numbers: Social Security number (SSN), passport number, driver’s license number, taxpayer identification number, patient identification number, financial account number, or credit card number
  • Personal address information: street address or email address
  • Personal telephone numbers: home phones or mobile phones
  • Personal characteristics: photographic images (particularly of face or other identifying characteristics) or handwriting
  • Biometric data: fingerprints, retina scans, voice signatures, or facial geometry
  • Information identifying personally owned property: Vehicle Identification Number (VIN), home or vehicle title number
  • Asset information: Internet Protocol (IP) or Media Access Control (MAC) addresses that consistently link to a particular person

Other pieces of data by themselves aren’t considered PII because they could be shared with other individuals. This information has become known as “linkable.” By combining them together, or linking to one of the above examples, they can be equally as appealing to fraudsters…and equally as harmful if exposed. PII may include your:

  • Date of birth
  • Place of birth
  • Business telephone number
  • Business mailing or email address
  • Race
  • Religion
  • Geographical indicators
  • Employment information
  • Medical information
  • Education information
  • Financial information

What Do Criminals Do with PII?

There are several malicious ways that cybercriminals and identity thieves use our PII. Through direct attacks, they can apply for loans or lines of credit, make purchases with our credit cards, steal our tax refunds, drain financial accounts, or more.

Another way that our PII is used is to commit synthetic identity theft. Synthetic identities are created when a fraudster combines someone’s Personally Identifiable Information with fake details. For example, a real Social Security number might be cobbled together with a fake name and address to create a new identity. If the thief uses this identity to commit a crime, you will be implicated because your Social Security number was used. According to the Federal Reserve, synthetic identity theft is the fastest-growing financial crime in the U.S.

The third way that criminals use our PII is to turn around and sell the stolen data on the dark web. Everything from social media credentials and credit card numbers, to medical records and Netflix passwords, can be sold by bad actors for criminal and financial gain on this underbelly of the internet. Hackers can make a pretty penny by capturing and offloading our data. In January of 2020, restaurant conglomerate Landry’s announced a point-of-sale malware attack that targeted customers’ payment card data in hundreds of popular restaurant locations across the country. The exposed PII included credit and debit card numbers, expiration dates, verification codes, and cardholder names. Similarly, in December 2019, East Coast convenience store chain Wawa experienced a malware attack on their payment processing servers, exposing as many as 30 million debit and credit card account numbers that were quickly found listed for sale on the dark web only weeks after the breach was reported.
