DICK'S Sporting Goods, the largest chain of sporting goods retail stores in the United States, disclosed that sensitive information was exposed in a cyberattack detected last Wednesday.

Cloud storage firm DropBox says hackers breached production systems for its DropBox Sign eSignature platform and gained access to authentication tokens, MFA keys, hashed passwords, and customer information.

Company officials said they aren't sure what led to the breach that has stretched across its properties nationwide.

Email marketing firm MailChimp suffered another breach after hackers accessed an internal customer support and account administration tool, allowing the threat actors to access the data of 133 customers.
