3. What information was affected by this issue?

The affected information included usernames, email addresses, and hashed passwords - the majority with the hashing function called bcrypt used to secure passwords.

The affected data did not include government-issued identifiers (such as Social Security numbers and driver's license numbers) because we don't collect that information from users. Payment card data was not affected because it is collected and processed separately.

4. What is a "hashed password"?

Hashing is a one-way mathematical function that converts an original string of data into a seemingly random string of characters.

5. What is "bcrypt"?

Bcrypt is a password hashing mechanism that incorporates security features, including multiple rounds of computation, to provide advanced protection against password cracking.

Below is contact information for the three consumer reporting agencies from which you can obtain a credit report.

You also may wish to place a "security freeze" (also known as a "credit freeze") on your credit file. A security freeze is designed to prevent potential creditors from accessing your credit file at the consumer reporting agencies without your consent. There may be fees for placing, lifting, and/or removing a security freeze, which generally range from $5-$20 per action. Unlike a fraud alert, you must place a security freeze on your credit file at each consumer reporting agency individually. For more information on security freezes, you may contact the three nationwide consumer reporting agencies or the FTC as described above. As the instructions for establishing a security freeze differ from state to state, please contact the three nationwide consumer reporting agencies to find out more information.

The consumer reporting agencies may require proper identification prior to honoring your request. For example, you may be asked to provide:

You have the right to obtain a police report and request a security freeze as described above. The consumer reporting agencies may charge you a fee of up to $10 to place a security freeze on your account, and may require that you provide certain personal information (such as your name, Social Security number, date of birth, and address) and proper identification (such as a copy of a government-issued ID card and a bill or statement) prior to honoring your request for a security freeze. There is no charge, however, to place, lift or remove a security freeze if you have been a victim of identity theft and you provide the consumer reporting agencies with a valid police report.
