Ctc.net data leak exposes 3,387 email records

A set of 3,387 email records tied to ctc.net was reportedly posted on Telegram, which means affected people may face an increased risk of scam emails, account sign-in attempts, or messages pretending to be from trusted companies. Even if the exposed information seems limited, it can still be used to target people with convincing fraud.


Who is at risk

People with a ctc.net email address, especially anyone who uses that email for banking, shopping, work, or other important accounts, is most at risk.

What to watch for

Watch for unexpected password reset emails, sign-in alerts, unusual account activity, or messages asking you to click links, share codes, or confirm personal information.

What to do

Change the password for your ctc.net email and any accounts that use the same password, turn on extra sign-in protection where available, and be cautious with unexpected messages.
