Why Sharing Your Birthday Online Can Fuel Identity Theft
Your date of birth is a key tool scammers use to impersonate banks and steal identities. Experts suggest keeping it off online accounts.
A date of birth may seem like harmless personal information, but cybersecurity experts warn it has become one of the most exploited data points in identity theft and fraud schemes targeting consumers.
Scammers routinely piece together names, addresses and birthdays — often harvested from social media profiles, data breaches, or public records — to construct a convincing portrait of their target.
