Executive Summary
In May 2022, MangaToon suffered a data breach exposing about 23 million subscriber records. The hacker known as pompompurin obtained the data from an Elasticsearch server secured only with the weak credential "password." Exposed data included names, email addresses, usernames, genders, avatars, social-media account identities, authentication tokens from social logins, and passwords stored as salted MD5 hashes.
ObscureIQ assessment: Exposure enables account takeover, phishing, and profiling based on reading behavior. Content preferences may also reveal age, language, or cultural-interest signals that improve targeting.
Breach Impact
Social-login auth tokens raise account-takeover risk for linked third-party accounts, while the profile and contact data supports phishing and credential-stuffing; salted MD5 offers only limited protection.
