It’s not clear why it took CCleaner several months to disclose the incident to affected customers. Gen Digital does not break down how many paid CCLeaner users it has, but claims to have about 65 million paid customers across its cybersecurity portfolio, which includes CCleaner. Monney said that less than 2% of users were affected, but declined to provide a specific number of affected users.ĬCleaner is used by millions of people around the world. Jess Monney, a spokesperson for Gen Digital, confirmed that customer phone numbers, email addresses and billing addresses were affected by the breach.
The email to customers said that the hackers took names, contact information and information about the products that were purchased. In an email sent to customers, Gen Digital, the multinational software company that owns CCleaner, Avast, NortonLifeLock and Avira brands, said that the hackers exploited a vulnerability in the widely used MOVEit file transfer tool, which is used by thousands of organizations, including CCleaner, to move large sets of sensitive data over the internet. The maker of the popular optimization app CCleaner has confirmed hackers stole a trove of personal information about its paid customers following a data breach in May.
