Time Warner Cable said the recent data breach that may have affected more than 300,000 customers had nothing to do with the company's systems or processes.
TWC said it was recently notified by the Federal Bureau of Investigation that data for 320,000 of its customers', including email addresses and account passwords, may have been compromised.
No evidence of a breach of TWC's systems that operate and secure email accounts for its customers was found, the company reported.
"TWC is proactively reaching out to those customers who could potentially be impacted so they can take precautionary measures to protect their accounts by changing their password using a strong, unique alternative," the company said in a statement released Thursday.
TWC said it has not been determined yet how the information was obtained. The company said the emails and passwords were likely previously stolen, either through malware downloaded during phishing attacks or indirectly through data breaches of other companies that stored TWC customer information.
Less than 2 percent of customers were impacted, TWC reported.
