The Washington DC Police released a statement following the Babuk Locker gang claimed they had compromised DC Police’s networks and were able to steal 250GB of unencrypted files.

A researcher has found that the credit scores of Americans are exposed due to an API tool used by the Experian credit bureau, left open on a lender site without security protection. The researcher found that he could access the credit scores with publicly available information such as name and date of birth. He was even able to build a command-line tool that let him automate lookups, even after entering all zeros in the fields for date of birth. Experian said it fixed the unprotected endpoint instance, but some researchers are concerned that other exposed Experian APIs might be out there, sitting unprotected.
