Brinztech Alert: Database Collection of SuperJob, HH.ru, and Trudvsem is on Sale

Dark Web News Analysis

A threat actor on a known cybercrime forum is advertising the alleged sale of a massive database compilation from Russia’s top job search platforms: SuperJob, HH.ru (HeadHunter), and Trudvsem.

This is not a new breach. The seller explicitly dates the data to 2022. My analysis confirms this aligns with a series of known, massive data leaks that occurred that year. This old data is now being repackaged and re-sold in a 2025 market that is already flooded with the PII of tens of millions of Russian citizens from more recent breaches at Sberbank, Yandex, and the Federal Bailiff Service (FSSP).

This dataset, however, remains exceptionally dangerous. It is a “goldmine” for social engineering, containing 20 million unique resumes and 16 million unique phone numbers. The data includes:

• Full PII (names, dates of birth, phones, emails)
• Detailed professional history (past and current employers, job titles)
• Current Salary Expectations

This provides a complete toolkit for criminals to conduct highly convincing Business Email Compromise (BEC), spear-phishing, and recruitment fraud attacks by impersonating executives or recruiters with pinpoint accuracy.

Key Cybersecurity Insights

This alleged data sale presents a critical and immediate threat:

• High Risk of Sophisticated Social Engineering: The combination of personal contact information, detailed professional history, and salary data provides malicious actors with a robust profile for crafting highly convincing spear-phishing campaigns, BEC attacks, or corporate espionage attempts.
• Extensive PII Exposure: The breach exposes a significant volume of Personally Identifiable Information (PII) and professional data, making individuals highly susceptible to identity theft, account takeover, and targeted social engineering attacks.
• Ongoing Value of Stolen Data: The active sale of 2022 data in a current hacker forum highlights the persistent value of compromised personal and professional data on the dark web, emphasizing long-term risks for affected individuals and organizations.
• Cross-Platform Credential Stuffing Potential: With 16 million unique phone numbers and email addresses, there is a high likelihood of users reusing passwords across different platforms, enabling attackers to perform credential stuffing attacks on other online services.

Mitigation Strategies

In response to this, all organizations and individuals must assume their professional data is public:

• Enforce Multi-Factor Authentication (MFA): Mandate and implement strong MFA across all corporate accounts and critical systems to significantly reduce the risk of unauthorized access, even if credentials are stolen from third-party breaches.
• Employee Cybersecurity Awareness Training: Conduct continuous training programs specifically focusing on advanced phishing and social engineering techniques. Employees must be trained to be suspicious of any unsolicited communication regarding job offers, HR policies, or financial matters that leverages their real career history.
• Dark Web Monitoring and Credential Scanning: Utilize dark web monitoring services to actively scan for leaked company or employee credentials and PII, enabling proactive password resets and fraud prevention measures.
• Data Minimization and Access Control: Regularly review and implement data minimization principles for all collected and stored personal data, ensuring only necessary information is retained, and enforce strict access controls.
