Brinztech Alert: Database of Libreria Antiquaria Pontremoli Leaked

Dark Web News Analysis

Cybersecurity intelligence from February 19, 2026, has identified a critical database exposure involving Libreria Antiquaria Pontremoli, an established name in the rare book and manuscript trade based in Milan. A threat actor on a prominent hacker forum has published a full SQL dump of the store’s web infrastructure, specifically targeting the database ca418mw3_pontremoli.

The breach reveals a comprehensive exfiltration of the bookstore’s operational and customer data. The structure of the leak suggests a successful SQL Injection (SQLi) attack, allowing the actor to bypass security and dump the following:

• Customer PII: Records for 705 clients in the clienti table, likely including full names, physical addresses, and contact details.
• Sensitive Financial Metadata: Tables such as fatturazioni (invoices) and carrello (shopping cart) may contain transaction histories and billing information.
• Account Credentials: The utenti table and a “dump mail hash” indicate that user account credentials and email addresses have been compromised.
• Proprietary Business Data: The ordini (orders) and prodotti (products) tables expose the store’s inventory and the purchasing habits of high-value collectors.

Key Cybersecurity Insights

The breach of an antiquarian specialist represents a “Tier 1” threat due to the high-profile nature of its clientele:

• Targeted “Collector” Phishing: Antiquarian book collectors are a high-net-worth demographic. Attackers can use the leaked ordini data to craft hyper-specific Spear-Phishing lures, impersonating the bookstore to offer “exclusive first-looks” at rare items to steal banking credentials or install malware.
• Credential Stuffing Synergy: The “mail hash” and utenti data provide a fresh list for Credential Stuffing. Attackers will test these email/password combinations against premium auction sites, private banking portals, and other luxury retailers where these collectors likely hold accounts.
• Corporate and Private Reconnaissance: By analyzing the prodotti and ordini tables, competitors or illicit art dealers can map the bookstore’s supply chain and identify its most lucrative clients, potentially leading to unauthorized “off-market” poaching or industrial espionage.
• Automated SQLi Exploitation: The presence of the information_schema in the leak confirms that the attacker used automated tools to map the server’s entire database structure, indicating that the website lacked basic input sanitization and a Web Application Firewall (WAF).

Mitigation Strategies

To protect your personal data and secure your collection’s privacy following this exposure, the following strategies are urgently recommended:

• Immediate Password and Session Reset: If you are a client of Libreria Antiquaria Pontremoli, change your account password immediately. If you reused this password for your primary email or online auction accounts, rotate those credentials across all platforms using a unique, complex passphrase.
• Urgent Vulnerability Remediation: The bookstore must conduct a forensic audit to patch the SQL Injection vulnerability. This includes implementing parameterized queries and a robust Web Application Firewall (WAF) to block automated database mapping attempts.
• Direct Customer Notification: Under GDPR regulations, the bookstore must notify its 705 affected clients. Transparency is critical to prevent follow-on phishing attacks that leverage the store’s reputation to defraud collectors.
• Enhanced Transaction Monitoring: Monitor for any unauthorized activity related to the “fatturazioni” data. Be skeptical of any unsolicited calls or emails from “Libreria Pontremoli” asking for “Bank Verification” or “Payment for Reserved Items.”
