Questel SAS
Attack Intelligence
Questel SAS was compromised in a ransomware attack attributed to shinyhunters in August 2026. The organization, operating in an undisclosed sector in France, was added to the group's data leak site as part of an extortion campaign.
shinyhunters operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.
Over 21 million Salesforce records containing some PII and 147GB+ of internal corporate data was compromised. This is a final warning to reach out by 4 August 2026 before we leak along with several annoying (digital) problems that'll come your way. Make the right decision, don't be the next headline.
