What Is Identity Theft? Types, Warning Signs, and Prevention
Identity theft occurs when someone uses your personal information — name, Social Security number, financial account details, or medical information — without your authorization to commit fraud or other crimes.
Understanding the different types of identity theft and how they occur is the foundation of effective prevention.
The Most Common Types of Identity Theft in 2025
Financial identity theft is the most common: using stolen credentials to open accounts, make purchases, or take out loans. Medical identity theft uses your information to obtain healthcare or prescriptions. Synthetic identity theft combines real and fabricated information to create a new identity.
In each case, the theft begins with access to personal data — much of which is available through data broker profiles before any breach occurs.
Reduce Your Attack Surface Proactively
The most effective identity theft prevention starts with reducing what is available about you through data brokers and dark web sources. CypherAvoid addresses both: broker profile removal reduces reconnaissance data, while dark web monitoring alerts you to credential exposures before they are used.
