Time Warner Cable freelancers managing online apps left the AWS S3 storage, which included subscriber data, vulnerable. According to Kromtech, independent contractors that managed online applications for Time Warner Cable (TWC) and other businesses ignored the AWS S3 storage that held subscriber data. In addition to phone numbers, usernames, MAC addresses, modem hardware serial numbers, account numbers, contact information, and other billing details, the exposed customer records also included addresses and phone numbers. TWC is informing affected customers of the data leak.

Over 320,000 Time Warner cable customers and some partner companies were targeted in malware and phishing attacks. FBI warned Time Warner that some of the customer data including usernames and passwords were compromised as they were attacked. After getting to know the details of the attack, they helped the customers whose account information was stolen, to make them aware and to help them reset their passwords.
