Synergy: a key player in data and cloud in France hit by ransomware

On 7 April 2026, Synergy — a French provider of data-management and cloud-services solutions — was reported to be the target of a ransomware-type cyberattack. The company supports clients on data management, transformation and governance projects, which sharpens the stakes of any compromise involving its systems or hosted environments.

The incident was described as involving unauthorised access to Synergy's systems. As is typical of ransomware operations, it likely followed a double-extortion model combining encryption of infrastructure with the threat of publishing exfiltrated data to force a negotiation. Because of Synergy's role handling large volumes of client data and cloud workloads, the potential exposure was considered significant.

At the time of reporting, key details remained undetermined:

• The identity of the ransomware group claiming the attack was not disclosed.
• The exact attack vector was not specified.
• No figure was given for the number of records, clients or systems affected.
• The categories of data potentially exposed (client data, project files) were not confirmed.

The situation was described as ongoing, with the full scope still being assessed. No regulator statement or company disclosure beyond the initial tracker report was available at the time of writing.
