The Pol Mira data breach has revealed a significant security flaw in the website of polmira.ru, a Russian flooring and home goods company. A hacker posted part of the company’s internal database on a dark web forum, sharing the data publicly instead of selling it. Although the exposed table contains low-sensitivity website content, cybersecurity experts warn that the leak is evidence of full backend access, including potential exposure of administrator credentials and personal information.
Background
Pol Mira (polmira.ru) is a Russian business specializing in flooring, construction, and home improvement materials. The leaked dataset includes fields such as id, menu_type, name, and description, showing that the attacker accessed the site’s Content Management System (CMS) database. These fields typically store information about web pages, product menus, and layout descriptions.
The data leak is small in size but highly significant. A hacker who can read or export CMS tables can usually access more sensitive data, including login credentials and password hashes. The incident points to an SQL injection or misconfigured server vulnerability that could allow full control over the company’s website and backend database.
- Leaked Fields: id, menu_type, name, description
- System Type: Website CMS database (likely WordPress, Joomla, or Bitrix)
- Leak Type: Public leak (free share) on a dark web forum
Key Cybersecurity Insights
1. The Leak Proves SQL-Level Access
Although the Pol Mira data breach appears minor, it proves that the attacker gained direct SQL access to the company’s database. If the attacker can export a non-sensitive table, they can almost certainly dump more critical ones such as users or wp_users. Those tables typically store user names, emails, and password hashes. This makes the breach far more serious than it appears at first glance.
2. Immediate Risk of Website Defacement or Malware Injection
The attacker likely still has access to the vulnerability that allowed the breach. With database-level control, they can deface the polmira.ru website, add hidden scripts, or upload webshells to maintain control. These actions could be used to distribute malware, run cryptocurrency miners, or redirect visitors to phishing pages. Once a site is compromised at this level, the attacker can persist even after the main flaw is patched.
3. Risk of Credential Theft and Password Reuse Attacks
If the users table was also accessed, email addresses and password hashes could be cracked offline. Once recovered, these credentials could be reused to attack other accounts belonging to Pol Mira employees or customers. Russian users often reuse the same passwords across platforms such as Mail.ru, Yandex, and VK, making credential stuffing a serious risk following the Pol Mira data breach.
4. Violation of Russian Data Protection Law (152-FZ)
The incident may fall under Federal Law No. 152-FZ “On Personal Data”, which governs how companies must secure and report data breaches in Russia. Even though the leaked dataset itself does not include personal information, the fact that the attacker had database-level access indicates a breach of systems that may store PII. Under the law, Pol Mira is obligated to report this incident to Roskomnadzor and take steps to mitigate the impact.
Mitigation Strategies
For Pol Mira (The Company)
- Patch All Vulnerabilities: Immediately perform a full web application vulnerability scan to locate and patch any SQL injection or authentication flaws.
- Reset All Passwords: Enforce a company-wide password reset for all user and administrator accounts.
- Perform a Server-Wide Security Audit: Check for unauthorized scripts, webshells, and database modifications. Restore clean backups where possible.
- Report to Roskomnadzor: File a report under Federal Law 152-FZ and notify any users whose information may have been compromised.
- Deploy a Web Application Firewall (WAF): Implement WAF protection and enable logging to prevent further exploitation.
For Affected Users
- Change Passwords Immediately: If you had an account on polmira.ru, assume your credentials were compromised and reset your password now.
- Do Not Reuse Passwords: Avoid using the same password on other services such as email, social networks, or banking platforms.
- Be Cautious of Phishing: Be alert for emails or messages claiming to come from Pol Mira or related sites requesting login verification.
- Run Security Scans: Use trusted tools like Malwarebytes to scan your devices for any malware infections.
The Pol Mira data breach serves as a warning to companies that even small or seemingly harmless leaks can reveal serious security weaknesses. Attackers often use minor leaks to test vulnerabilities before launching larger attacks. This case underscores the importance of continuous patching, strong access control, and proactive threat monitoring to prevent full database compromise.
