In 2023, the Leboncoin platform detected a 30% increase in phishing attempts targeting its users. Some fraudulent listings still evade detection algorithms, despite strengthened controls. Organized networks exploit vulnerabilities in online payment systems and the trust between individuals to divert funds or steal personal data.
Platforms must continuously adapt their security protocols in the face of increasingly sophisticated fraud methods. The effectiveness of measures depends as much on the technology in place as on the vigilance of users during transactions.

What are the main phishing risks on online classifieds platforms?
Phishing is making its way onto online classifieds platforms with an ingenuity that demands attention. Fraudsters capitalize on the speed of exchanges, the trust that develops between sellers and buyers, and the massive visibility offered by classified platforms and social networks. With millions of active users connected daily, these spaces become hunting grounds for increasingly organized cybercriminals.
Here are the most common traps that threaten sellers and buyers:

- Credential theft: Scammers send fake messages, perfectly imitating the platform’s interface. The user, convinced they are dealing with an official service or a legitimate contact, unknowingly shares their access credentials. Fraudsters then take control of member listings, modifying or deleting transactions.
- Fake payments: Fake transfer proofs flood in, often through messaging services from social networks or platforms. The seller ships the product, but the payment never arrives.
- Personal data collection: Postal address, phone number, or even a copy of an ID, everything circulates on platforms or social networks. This information feeds an underground market where digital fraud thrives.
In the face of these increasingly clever strategies, every user must exercise extra caution. Posting an ad, selling an item, or managing an account online now exposes individuals to real risks, both for private users and for the technical managers of the platforms. An unusual link, a suspicious request regarding member listings management: any doubt should trigger an alert.
Concrete measures and tips to secure your transactions and protect your personal data
Buying and selling between individuals online is no longer trivial. Platforms, aware of the rise in fraud, are investing in cutting-edge detection tools. Artificial intelligence scans for suspicious behaviors, while personal data protection becomes a central focus of their policy. Active monitoring allows for quick responses, but nothing replaces human vigilance.
Since the implementation of the Digital Services Act, online platforms have been assigned new responsibilities. They must report illegal content more promptly and play the transparency card regarding the use of personal data. On the users’ side, a few simple reflexes make all the difference:
- Always check the website address and look for the “https” mention before managing your listings online.
- Never share more information than necessary: phone numbers and bank details should only be shared with discretion.
- Whether you are a seller or a buyer, prefer the internal messaging systems offered by the platforms, which are often safer than conversations on social networks.
- If the platform allows it, enable enhanced authentication: two-factor authentication, real-time alerts, regular checks of your login history.
The new rules also enhance the security of SMEs and individuals. Every information share must be weighed: an address, a number, a simple image can, if misused, fuel other online scams. Data protection is no longer just a box to check; it becomes a comprehensive approach that concerns every stakeholder, every connected citizen.
In the digital realm, security is never guaranteed. Fraudsters sharpen their methods, platforms retaliate, and users learn to navigate between vigilance and trust. The cat-and-mouse game continues, but the story will not be written without us.
