10 Data Breach Statistics Every IT Department Should Know About

Kroger, T-Mobile, Microsoft Exchange, California DMV, Facebook, LinkedIn, Experian, Bose. Just a handful of hundreds of companies that have experienced a data breach in the first half of 2021 alone. The list goes on… including even the email security company Mimecast. As a result, millions of people are now at risk of identity theft and fraud, thanks to these cyberattacks.

What Would You Be Risking?

Security breaches don’t discriminate when it comes to the types of companies they target. So far this year, hackers have infiltrated social media companies, grocery and food supply chains, medical treatment centers, and even online dating sites (which exposed some really sensitive information!)

So, ask yourself a question. If your company is currently being targeted, what kinds of information could cybercriminals expose about your customers? What’s at risk?

Some hacker favorites include:

  • Personally Identifiable Information (PII), such as customer names, phone numbers, date of birth, and physical addresses
  • Health insurance information and confidential lab results and diagnosis details
  • Work-related personal data, including names and titles to be used in future CEO impersonation attempts
  • Payment information, including the last four digits of credit cards
  • Social media handles, user names, and account IDs
  • Driver’s license, passport, and social security numbers
  • Investment account numbers
  • Vaccine and medication details
