Brinztech Alert: Database of Wir kaufen deinen Flug Leaked

Dark Web News Analysis

Cybersecurity intelligence from February 18, 2026, has identified a high-priority data exposure involving Wir kaufen deinen Flug (We Buy Your Flight), a German-based service that helps travelers claim compensation for flight delays. A threat actor on a prominent hacker forum has published samples of the company’s internal databases, with a threat to release the full archive within 12 hours.

The exfiltrated data is highly structured and contains everything needed for sophisticated financial fraud. The presence of wp_users.csv suggests a potential compromise of the platform’s core CMS (WordPress), while the rp_ prefix files indicate exfiltration from the company’s primary claims management system. The leaked data includes:

• Financial Credentials: Comprehensive bank details including BIC, IBAN, and Bank Names.
• Personally Identifiable Information (PII): Full names, physical home addresses, and verified mobile phone numbers.
• Account Metadata: User IDs, email addresses, and potential password hashes from the web portal.
• Claim History: Documentation related to flight compensation requests, which includes travel details and legal signatures.

Key Cybersecurity Insights

The breach of a flight compensation company represents a “Tier 1” threat due to the high density of financial and legal documentation:

• Direct Banking Fraud and “SEPA” Abuse: With verified IBANs and physical addresses, attackers can initiate unauthorized SEPA Direct Debits or commit “Incasso” fraud. This is particularly dangerous in the DACH region where bank-to-bank transfers are common.
• Credential Stuffing Synergy: The exposure of the wp_users table provides a “hit list” for Credential Stuffing. Attackers will use the email and password combinations to attempt logins on major airlines, loyalty programs, and German banking apps.
• Hyper-Targeted Phishing: Scammers can use the specific claim data to craft lures that are nearly impossible to detect. A customer waiting for a €600 compensation payment is highly likely to click a link in an email that correctly identifies their bank and flight number.
• Imminent Full Release Strategy: The threat actor’s 12-hour ultimatum suggests a “Fast-Leak” strategy. This aims to maximize the resale value of the data before the company can notify users or banks can flag the accounts, necessitating an immediate defensive response.

Mitigation Strategies

To protect your financial identity and secure your digital presence following this exposure, the following strategies are urgently recommended:

• Immediate Password Rotation and Session Reset: If you are a customer of Wir kaufen deinen Flug, change your account password immediately. If you reused that password for your Email, Amazon, or Online Banking, rotate those credentials across all platforms using a unique, complex passphrase.
• Bank Account Monitoring (IBAN/BIC): Contact your bank immediately if you have shared your IBAN with this service. Request a “Direct Debit Block” for any new or unauthorized vendors and monitor your statements daily for the next 90 days.
• Enforce MFA on All Linked Accounts: Ensure that your primary email and any travel-related accounts are protected by App-Based MFA or Hardware Security Keys. This prevents attackers from hijacking your accounts even if they have your leaked credentials.
• Transparent Incident Response: The company must activate its data breach notification protocols under GDPR. This includes notifying the relevant German Data Protection Authority and providing clear, actionable steps for their users to protect their financial accounts.
