Timeline
CLAIMED
August 22, 2026
The hacker "misere" publishes a claim on a criminal forum
covering several databases attributed to Solimut Mutuelle de France: national ID
numbers, identities, contact details, IBAN, BIC, professional information and payroll
data of insured members and other people registered in the systems.
UNCONFIRMED
Since
The hacker details the claim: 1,244,445 insured-member records,
770,467 bank accounts, over 1.38 million records with national ID numbers, and over
1.08 million payroll declarations. Authenticity, exact origin and the real number of
unique individuals affected remain to be independently confirmed. No public
confirmation from Solimut has been identified to date.
🆔The combination that raises concern: health, banking and
payroll
What sets this claim apart from other health-insurer leaks documented here (MGP,
Compte Asso) is the claimed combination of three data categories at once: national ID,
bank details, and payroll data. If genuine, it would allow building a near-complete
administrative and financial profile of a person — far beyond a simple address or
email.
What it changes for you
If you are or were insured with Solimut Mutuelle de France, your national ID number,
bank details and payroll data could be in this claim — pending confirmation. The main risk
is administrative identity theft or wire-transfer fraud relying on real details from your
file. See From Leak to Scam.
🔒 A national ID number cannot be changed: stay vigilant
long-term against any solicitation citing this number, even months after this claim. No
legitimate organization will ask for it by email or phone for "verification."
