French fintech leader Harvest SAS has become the latest high-profile victim of a sophisticated ransomware attack, culminating this week in the public release of a trove of sensitive stolen data.
The breach, orchestrated by the rapidly emerging cybercriminal group known as Run Some Wares, underscores the mounting threats facing financial technology firms and their clients worldwide, as per a report by CybelAngel.
A Targeted Attack on a Fintech Pioneer
Harvest, headquartered in Paris, has been a mainstay of digital innovation for wealth management professionals, providing a suite of platforms aimed at streamlining asset management, portfolio construction, and financial analysis.
On April 10, 2025, Run Some Wares claimed responsibility for hacking the company’s website (harvest[.]eu), marking their entry into the European fintech sector.

The incursion was first detected internally on February 27 but went public only in April, when Harvest issued a statement disclosing a “cyber incident” that had impacted internal systems.
Within days, Run Some Wares began leaking samples of the stolen files on their dark web site, and today, the group has fully exposed the compromised directory—making comprehensive internal and client data available for public download.

Analysis reveals that Run Some Wares exfiltrated vast segments of confidential information, leveraging a “double extortion” technique: encrypting Harvest’s data while threatening disclosure to coerce payment. The leaked files, now public, include:
- Business Operations: Internal strategies, project documents, and organizational charts.
- Financial and Payroll Records: Accounting data, payroll information, and quality assurance files.
- Employee Information: Employment contracts, HR evaluations, and confidential personnel documents.
- Access Credentials: Password vaults, encryption keys, and internal authentication data.
- Legal and Compliance Files: Contracts, audit documents, and regulatory reviews.
- Technical Assets: Source code, AI models, and infrastructure configurations.
- Client and Third-Party Information: Potentially exposing partners to downstream risks.
- Internal Communications: Email archives, heightening the risk of phishing and further social engineering.
The scope of the disclosed data extends into almost every operational aspect of Harvest, escalating risks of fraud, identity theft, and regulatory penalties.
Run Some Wares has quickly solidified its notoriety since emerging onto the ransomware scene.
Not confined to a particular industry, the group specializes in high-impact double extortion attacks across the finance and manufacturing sectors.
To date, they have claimed at least five major victims globally—illustrating both operational maturity and reach.
The breach serves as a stark warning to organizations handling sensitive data: ransomware groups are evolving, and their tactics are growing more aggressive.
Financial service providers, in particular, face mounting risks due to the value and interconnectedness of their data.
CybelAngel urges companies to remain vigilant, utilize dark web monitoring tools, and have proactive remediation plans in place.
