Comcast Data Breach

In November 2015, the US internet and cable TV provider Comcast suffered a data breach that exposed 590k customer email addresses and plain text passwords. A further 27k accounts appeared with home addresses with the entire data set being sold on underground forums.

Exposed data

Recommended actions

• Change your Comcast password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Comcast — attackers weaponise breach data quickly.
• Exposed identity data raises identity-theft risk — consider credit monitoring or a credit freeze.
• Check whether your email address appears in this breach on haveibeenpwned.com.
