Brinztech Alert: The Alleged Database of 1PaySolution is on Sale

Dark Web News Analysis

The dark web news reports a significant data breach involving 1PaySolution, a payment gateway and recharge platform. A threat actor on a hacker forum is actively selling a database allegedly belonging to the company.

The dataset is substantial, containing approximately 4 million records spread across 371 CSV files. It totals 6.47 GB (1.36 GB compressed). The seller has set a high asking price of 7,500 USDT and is willing to use escrow services, indicating confidence in the data’s quality. The leaked files reportedly contain sensitive Request/Response Logs, which typically include Transaction Details, IP Addresses, and potentially unmasked Personally Identifiable Information (PII) of users.

Key Cybersecurity Insights

Breaches of payment aggregators or B2B recharge APIs are “Tier 1” financial threats because they sit at the intersection of banking and retail:

• Transaction Replay & Manipulation: The exposure of Request/Response Data is the most technical risk. If these logs contain API keys, session tokens, or checksum logic, attackers can analyze how 1PaySolution verifies transactions. They could attempt “Replay Attacks” to duplicate legitimate payments or “Parameter Tampering” to alter transaction values in transit.
• The “Digital Trail” Exposure: Payment logs often contain metadata like IP Addresses, User Agents, and Device IDs. This data allows attackers to de-anonymize high-volume traders or merchants, mapping their physical locations and digital habits for targeted attacks.
• Merchant & Agent Compromise: 1PaySolution services a network of B2B agents. The leak of 4 million records likely exposes the entire agent hierarchy. Attackers can target these agents with “Chargeback Scams,” claiming a transaction failed (using data from the leak as proof) and demanding a refund to a fraudulent account.
• Third-Party Domino Effect: Even if 1PaySolution’s core banking interface is secure, a breach of their “Recharge API” or “Bill Payment” subsystem exposes the end-users of every partner company that integrated their services.

Mitigation Strategies

To protect financial integrity and partner trust, the following strategies are recommended:

• API Key Rotation: 1PaySolution and all its B2B partners must immediately rotate all API keys and secret tokens used to sign transactions.
• Log Analysis: The security team should analyze the sample data to determine if the leak originated from a misconfigured cloud storage bucket (e.g., S3) storing debug logs, or an SQL injection in the reporting dashboard.
• End-User Notification: Users should be warned to monitor their bank statements for unauthorized small transactions, which are often used by criminals to test the validity of stolen card data.
• Rate Limiting & IP Whitelisting: Enforce strict IP whitelisting for all B2B API connections to ensure that stolen credentials cannot be used from unauthorized locations.
