Experts are warning everyone to keep a close eye on any sensitive information you have out there on the internet.

Security experts say a flaw in the encryption software that protects information like your passwords and financial information has exposed millions of people to possible theft and fraud.

The "heart bleed" bug was discovered only recently and is believed to have been a problem for at least 2 years.

Protecting yourself will not be easy.  Experts say the best thing is to check with any businesses you have accounts with and then prepare to start changing passwords.
