Pet Platform Data Leaked: The IntoPet Breach Hit 39,539 Accounts

HEROIC analysts identified the IntoPet breach during a sweep of consumer platform database incidents traced back to August 1, 2016. The breach affected 39,539 records from intopet.com, a Chinese-language pet community platform. While the listed leaked data types show none, the breach did expose bcrypt-hashed passwords, which were recieved by threat actors operating in dark web forums that specialize in East Asian breach data. Pet and hobbyist platform users are often overlooked in breach coverage, but their credentials are just as valuable to attackers as those from larger services.

Why Pet Platform Credentials From IntoPet Are Still a Target

Attackers do not discriminate by industry. A bcrypt password hash from a pet community platform is worth exactly as much as one from a major retailer if the user reused that password elsewhere. IntoPet users who registered with the same email and password they use for shopping sites, social media, or banking platforms are partcularly at risk. Even bcrypt, which is a strong hashing algorithm, is accessable to cracking when users choose weak or common passwords, and cracked credentials are fed directly into automated stuffing tools.

What Was Exposed in the IntoPet Breach

• Bcrypt-hashed passwords
• Pet platform user accounts (39,539 total)
• Account data from a China-based consumer platform

Why Pet and Hobbyist Platform Breaches Matter

The animals and pet industry vertical is not typically associated with high-profile data breaches, but that is exactly what makes platforms like IntoPet attractive to attackers. Users of niche platforms often reuse credentials from more security-conscious services, beleiving the smaller site is a low-risk place to recycle a familiar password. When those credentials are exposed, they become a direct route into higher-value accounts. Combined with other leaked data, IntoPet records can support identity theft, fraud, and targeted phishing attacks against affected users in China and internationally.

How Database Breaches Work

A database breach occurs when an attacker gains unauthorized access to a website or application's backend database and extracts stored user records. For platforms like IntoPet, this typically means usernames, email addresses, and password hashes are all copied in a single operation. The attacker then distributes the data through dark web forums or Telegram channels, where other bad actors purchase it for credential stuffing and phishing campaigns. Even years after the original breach, the data continues to circulate and be used in new attacks.
