Brinztech Alert: IBAN Data of French Citizens are on Sale

Dark Web News Analysis

A threat actor on a known cybercrime forum is claiming to sell a database that they describe as containing “fresh” IBAN data of French citizens. The seller is using direct contact methods, including Telegram and Skype, to facilitate the sale to interested parties.

This claim, if true, represents a direct and serious threat to the financial security of numerous individuals in France. An IBAN (International Bank Account Number) is a key piece of financial information. ¹ In the hands of criminals, it can be used to attempt a variety of fraudulent activities, most notably setting up unauthorized direct debits from victims’ bank accounts. The seller’s claim that the data is “fresh” is a tactic used to imply it was stolen recently and is therefore more likely to be active and valuable for fraud. A breach of this nature would also constitute a severe violation of Europe’s General Data Protection Regulation (GDPR), leading to a major investigation into the source organization.  

Key Cybersecurity Insights

This alleged data sale presents a critical and immediate financial threat:

• Direct Risk of Financial Fraud: The primary threat is the potential for direct financial theft. Criminals can use stolen IBANs, often in combination with publicly available information, to set up fraudulent direct debits (known as prélèvements SEPA in France), siphoning money from victims’ accounts.
• “Freshness” Claim Increases Urgency: The assertion that the IBAN data is “fresh” is intended to signal its high quality to other criminals. It suggests the information was recently compromised and is less likely to be associated with closed accounts, increasing the urgency for financial institutions and potential victims to act quickly.
• Severe GDPR Compliance Failure: A confirmed leak of financial identifiers like IBANs would be a major compliance failure for the source organization under GDPR. It would trigger a mandatory investigation by France’s data protection authority (CNIL) and would likely result in significant financial penalties.

Mitigation Strategies

In response to a threat of this nature, French financial institutions and citizens must be on high alert:

• Launch an Immediate Investigation by French Authorities: French financial regulators, such as the ACPR, and cybersecurity agencies like ANSSI should immediately investigate this claim to verify its authenticity and make every effort to identify the source of the leak.
• Issue a Nationwide Alert to Citizens and Banks: A widespread alert should be issued, warning French citizens to meticulously monitor their bank statements for any unfamiliar or unauthorized direct debits. All French banks must be on high alert and should enhance their fraud detection systems to identify and block suspicious debit requests.
• Strengthen Security on all Payment Systems: All companies operating in France that process or store customer IBANs must conduct an urgent review of their security measures. This includes ensuring that this sensitive data is properly encrypted, access is strictly controlled, and their systems are protected against intrusion.
