Time Warner Cable said Wednesday that up to 320,000 customers may have had their email passwords stolen from phishing attacks.

Reuters reports the company said it has not yet determined how the information was obtained, but there were no indications that Time Warner Cable’s systems were breached.

The company said email and password details were likely collected through malware from phishing attacks or indirectly through data breaches of other companies that stored Time Warner Cable’s customer information, including email addresses.

The latest breach comes two months after Comcast reset the email passwords of about 200,000 customers because they were listed for sale online.
