The French childcare payroll service Pajemploi has confirmed a major data breach affecting up to 1.2 million home-based childcare workers, after a cyberattack detected in mid-November. Personal data belonging to childcare employees may have been stolen in the attack, raising concerns over potential dark-web leaks and identity theft risks.
ajemploi, a French government service used by parents and home-based childcare workers, has disclosed a major data breach that may have exposed personal information belonging to 1.2 million people. The platform, which is operated under URSSAF, manages payroll and social security declarations for parents employing registered childcare providers. The breach affects professional caregivers employed directly by families who rely on Pajemploi for processing salaries and social contributions.
In its announcement, the agency confirmed that Pajemploi "was the victim of a theft of personal data belonging to employees of private employers using the Pajemploi service." The cyberattack was detected on November 14, and investigators believe it may have compromised sensitive information tied to as many as 1.2 million childcare workers across France.

Personal employment information
While Pajemploi has not yet disclosed the specific data elements accessed, breaches involving employment records often include names, contact information, national identifiers, banking details, social security numbers, and employment history—all of which are valuable to cybercriminals and frequently end up circulating on dark-web marketplaces.
"This breach represents a significant threat to the privacy and financial security of hundreds of thousands of childcare workers across France," explained cybersecurity analyst Marie Dubois. "Employment data is particularly valuable on the dark web because it can be used for identity theft, tax fraud, and sophisticated phishing campaigns. The fact that this involves a government-operated service makes the potential impact even more severe."
Authorities have not clarified who is responsible for the attack or whether stolen data has appeared online, but cybersecurity officials warn that incidents involving large public-sector systems are increasingly targeted by threat actors seeking financial gain or leverage. Data from government services often commands premium prices on dark web forums due to its completeness and reliability.
URSSAF and Pajemploi say they have taken steps to secure the affected systems and are working with relevant agencies to evaluate the scope of the breach. Impacted workers are expected to receive direct notification as the investigation continues. The French data protection authority (CNIL) has been notified as required by the General Data Protection Regulation (GDPR).

The incident highlights the vulnerabilities in government digital services that handle sensitive personal information. Pajemploi serves as a critical platform connecting families with childcare providers, processing payments, and managing employment declarations. Its compromise could have far-reaching consequences beyond immediate data theft, potentially affecting the livelihoods and privacy of workers who rely on the service for their employment.
Based on similar breaches involving employment platforms, security experts have identified several categories of data that may have been compromised:
Full names, dates of birth, addresses
Email addresses, phone numbers
Bank account details, payment history
Employment dates, salary information, contract details
Social security numbers, tax identification
Account credentials, security questions
"Each piece of data has different values on dark web markets," explained cybersecurity researcher Sophie Martin. "Complete identity packages including banking information can sell for hundreds of euros. The scale of this breach—1.2 million potential victims—makes it one of the most significant data security incidents in France's public sector this year."
Cybersecurity experts are recommending several immediate actions for childcare workers who may have been affected by the breach:
Watch for official notifications from Pajemploi/URSSAF
Immediately update Pajemploi and related account passwords
Review bank statements for unauthorized transactions
Activate two-factor authentication where available
Consider credit monitoring services for fraud detection
Contact banks and authorities about any fraud attempts
Workers should be particularly vigilant for phishing attempts that may reference the breach or appear to come from Pajemploi or URSSAF. Cybercriminals often use news of data breaches to launch secondary attacks, sending fake notifications that contain malware or attempt to steal additional information.
The incident adds to a growing list of large-scale data compromises involving European public services, raising concerns about digital security standards and the risk of mass identity theft. Recent months have seen similar breaches affecting healthcare systems, educational institutions, and social services across the continent.
| Country | Affected Service | Date | Victims | Data Type |
|---|---|---|---|---|
| France | Pajemploi | November 2025 | 1.2 million | Employment data |
| Italy | Railway IT Provider | December 2025 | Unknown | Corporate data (2.3TB) |
| Germany | Health Insurance | October 2025 | 800,000 | Medical records |
| Spain | University System | September 2025 | 500,000 | Academic records |
| Netherlands | Tax Authority | August 2025 | 1.5 million | Tax information |
French authorities have launched a comprehensive investigation into the breach, involving cybersecurity experts from the National Cybersecurity Agency of France (ANSSI) and digital crime units. The investigation will focus on several key areas:
Pajemploi has established a dedicated support channel for affected users and is working on implementing enhanced security measures, including stronger encryption, improved access controls, and more rigorous monitoring systems. The service has also committed to regular security audits and penetration testing to prevent future breaches.
Beyond immediate fraud risks, data breaches of this scale can have long-term consequences for affected individuals. Stolen personal information can remain in circulation on dark web forums for years, resurfacing in various criminal schemes. Experts recommend several protective measures:
Maintain monitoring for several years post-breach
Consider identity theft protection services
Keep records of breach notifications and responses
Understand GDPR rights regarding data breaches
Implement additional banking security measures
Access cybersecurity awareness training
The Pajemploi breach serves as a stark reminder of the evolving threats facing digital public services and the importance of robust cybersecurity measures. As government services increasingly move online, ensuring the protection of sensitive personal data must remain a top priority to maintain public trust and prevent widespread harm from cyberattacks.
