Recent cyberattacks in France, including a significant breach at Free, have raised concerns about the theft of personal data and the resulting risks. While a stolen IBAN alone may not cause harm, when combined with other personal information, it can lead to fraudulent direct debits and scams. Individuals are advised to monitor their bank accounts regularly and utilize available resources for protection and reporting fraud. The evolving sophistication of cybercriminals amplifies the need for increased awareness and preventive measures.
Recently, France has faced a surge in cyberattacks, with significant breaches impacting companies like SFR, Libération, Boulanger, and Free. These attacks have led to the exposure of millions of personal records, including a staggering 5 million IBAN numbers linked to Free’s recent security compromise.
People are beginning to question the actual risks associated with compromised IBANs. The answer is yes, there is a legitimate concern.
While a stolen IBAN by itself may not directly harm your accounts, it becomes a serious threat when combined with other personal information. Past incidents and ongoing cyber threats indicate that these types of attacks are likely to escalate. Fortunately, there are measures individuals can take to enhance their security.

Understanding the Risks of Hacked IBANs
Believing that a stolen IBAN poses no dangers is like leaving the door to your bank account wide open. This misconception often leads to complacency regarding security. While phishing scams typically involve personal data theft, the theft of an IBAN can have severe repercussions, including unauthorized direct debits.
With access to your IBAN, a hacker can create fraudulent direct debit authorizations. For example, the Signal-Arnaques platform reported numerous unauthorized deductions last year, where victims lost hundreds of euros due to fake SEPA mandates crafted from stolen IBAN records.
Fraudulent direct debit authorizations could also allow a hacker to subscribe to services in your name, racking up expenses at your cost. If hackers gain access to additional personal data, such as your postal address or telephone number, the risk increases significantly, empowering them to forge greater schemes.
Aside from direct debits, a stolen IBAN could lead to various scams, like the fake bank advisor fraud. Here, a hacker masquerading as a bank representative might attempt to verify personal details such as your date of birth or IBAN. Remember, legitimate bank advisors will never solicit sensitive information from you—there’s no need for it.
According to ethical hacker SaxX, an IBAN can even be manipulated to redirect incoming payments, such as your salary, into a hacker’s account.
Therefore, it is crucial to regularly check your account statements. Taking just a few minutes daily to monitor transactions can help you catch unauthorized withdrawals early. If you spot anything unusual, report it to your bank immediately.
Are Banks Required to Reimburse Fraud Victims?
If you fall victim to fraud, your bank may bear legal responsibility. This could stem from their failure to detect abnormal direct debits or from lapses in security.
Banking regulations mandate the implementation of strong authentication measures for online transactions (as specified in Article L133-44 of the French Monetary and Financial Code). Such measures include SMS validation codes or the 3-D Secure protocol, which requires additional verification steps for payments.
You have 13 months from the date of any unauthorized or erroneous transaction to notify your bank (under Article L133-24). Upon reporting the fraud, your bank is obligated to reimburse you by the end of the next business day, barring delays due to weekends or holidays. Delays in reimbursement may incur interest on the owed amounts (Article L133-18).
The bank can only deny reimbursement under specific conditions, such as proving gross negligence or if the bank itself initiated the fraud (Article L133-19).
Tools and Tips for Protecting Against Fraud
Adopting preventive habits in daily life can significantly reduce your risk of falling victim to data theft and cyberattacks:
Since changing a bank account is often not a practical solution, taking proactive measures is essential.
Government resources like cybermalveillance.gouv.fr offer guidance on cybersecurity and assistance for online fraud victims. The CNIL website also provides valuable advice on safeguarding your personal information and understanding your rights.
If you’ve experienced an online scam, the THESEE platform allows you to file a complaint, while the Perceval platform is designed for reporting credit card fraud.

The Evolving Landscape of Cybersecurity Threats
The impact of even minor cyberattacks should never be underestimated. An IBAN alone may not lead to extensive damages, but when combined with other stolen data, a hacker’s potential to exploit your finances increases dramatically.
