Our Analysts Found the Lieper Books Database Exposed, Leaking 6,251 User Records

HEROIC analysts discovered a data breach affecting Lieper Books, an India-based e-commerce and social media platform built for book enthusiasts. The breach was identified on September 11, 2024, and involved 6,251 user records pulled directly from the platform's database. The exposed data included names, email addresses, phone numbers, and usernames. While the scale is smaller than major platform breaches, the combination of personally identifiable information in this dump gives attackers everything they need to target affected users directly.

Personal information like full names paired with email addresses and phone numbers is the raw material for social engineering. Attackers who obtain this data can craft convincing phishing messages, impersonate service representatives, or use phone numbers for SIM-swapping attacks. Because Lieper Books serves a niche community of readers, the attacker has the added advantage of knowing something personal about each target, which makes phishing attempts more believable and harder for victims to detect.

What Was Exposed

• Email Address
• Phone Number
• Username
• First Name
• Last Name

Why This Matters

Even without passwords in the dump, this data creates real risk. Full names combined with email addresses and phone numbers are enough to open accounts in victims' names, bypass knowledge-based authentication questions, or carry out targeted phishing at scale. Identity theft does not require a password when the attacker already knows enough about the victim to impersonate them. Phone numbers specifically are valuable for account recovery exploits and SIM-swapping, which can lead to full account takeover across banking and social media platforms.

How Database Breaches Work

Database breaches occur when an attacker gains unauthorized access to a web application's backend data store and copies its contents. This typically happens through SQL injection attacks, exploiting misconfigured database permissions, compromised admin credentials, or vulnerabilities in the platform's software stack. Once inside, the attacker can extract structured tables of user data silently and without disrupting normal site operation. The victim organization often does not detect the breach until the data appears for sale or distribution online. For smaller platforms like Lieper Books, security resources are often limited, making them attractive targets.
