€3.5 Million Fraud: French Authorities Dismantle Massive Fake Sick Leave Network
French authorities have dismantled a sophisticated fraud ring in the Île-de-France region that siphoned millions from the national healthcare system. In early May, seven individuals were arrested and placed in police custody for their suspected roles as the architects of a network that provided forged medical certificates to nearly 1,200 insured individuals in Seine-Saint-Denis.
The investigation, led by the Office central de lutte contre le travail illégal (OCLTI), reveals a calculated operation that diverted approximately €3.5 million from the Assurance maladie between May 2024 and November 2025. The scheme combined social media recruitment with identity theft to exploit the state’s daily allowance system.
The Digital Recruitment Strategy
Unlike traditional fraud rings, this network leveraged Snapchat to recruit participants. The scammers advertised a streamlined process for obtaining government benefits, promising daily allowances (indemnités journalières) ranging from €4,000 to €8,000, claiming they could handle the entire process within two weeks.
To participate, targets provided the network with sensitive personal data, including:
- Full contact coordinates
- Social Security numbers
- Photographs of their Carte Vitale (the French national health insurance card)
The “Kit” and the Kickback Model
Once the personal information was secured, the fraudsters provided the participants with a “kit” designed to deceive the health insurance fund. According to José Montull, head of the OCLTI, this kit consisted of a forged medical leave certificate and a fake salary statement to be submitted to the Assurance maladie.
The operation functioned on a profit-sharing basis. In exchange for the forged documentation and the resulting government payouts, the participants were required to kick back 60% of the received benefits to the organizers of the scam.
Systemic Exploitation and Identity Theft
A critical finding of the investigation is that no licensed physicians were accomplices in the scheme. Instead, the network engaged in identity theft, usurping the names and professional credentials of real practitioners to sign off on fictitious, long-term sick leaves. Some of these forged certificates spanned up to 100 days to maximize the payout from the state.
- Total Loss: €3.5 million diverted from public funds.
- Scale: Nearly 1,200 participants in Seine-Saint-Denis.
- Method: Recruitment via Snapchat and the use of forged “kits.”
- Mechanism: Identity theft of doctors to create long-term (up to 100-day) fake sick leaves.
- Profit Share: Scammers took a 60% cut of all fraudulent benefits.
Looking Ahead
This case highlights a growing trend of “digitalized” social security fraud, where social media platforms are used to scale illegal activities. As the OCLTI continues its investigation, the focus remains on the recovery of the diverted funds and the prosecution of the “masterminds” behind the network. For the Assurance maladie, the case underscores the urgent need for enhanced verification protocols to prevent the use of usurped professional identities in the claims process.
