What information is involved in the Sunnyvale Elementary School District Data Breach?
Compromised information may include:
Name and other personal data referenced in emails or attachments
Your Personally Identifiable Information (PII) includes details that can be used to identify you. It plays a key role in defining your identity. Organizations are legally obligated to safeguard this data, and failure to do so can result in statutory fines and other legal consequences. If PII is stolen, it may be exploited by criminals to commit identity fraud.
A specific category of PII is Protected Health Information (PHI), which pertains to personal medical data. PHI is safeguarded under both federal and state regulations. Entities such as healthcare providers and businesses that manage PHI must ensure its security. Just like PII, compromised PHI can be misused by identity thieves, and it’s common for cybercriminals to use both types of information together.
If your data has been exposed in a breach, one of the most effective steps you can take is to enroll in credit and identity monitoring services promptly.
Residents of California benefit from additional privacy protections under the California Consumer Privacy Act (CCPA), which grants enhanced rights regarding personal data.
If you received a NOTICE OF DATA BREACH letter from Discord, and you are a resident of California, your personal, financial, and/or medical information may be at risk. This type of data can be exploited by identity thieves to commit fraud and other crimes.
