Some online malware analysis services share submitted files with security firms
See how this story connectsSome online malware analysis services share files submitted by users with security companies and researchers to improve threat detection, which can expose information unintentionally. Google-affiliated VirusTotal, OPSWAT’s MetaDefender Cloud (for standard, non-private scans) and Jotti’s Malware Scan state this in their documentation. In April 2025, more than 1,700 documents containing sensitive corporate information were reportedly submitted to ANY.RUN’s public analysis after Microsoft security products wrongly flagged some files as malicious. ANY.RUN later switched the related analysis to private.
Why it matters
Users and organisations should check a service’s file-sharing policy before uploading documents containing personal data, corporate confidential information or account details, and should use private scanning options or internal security systems for sensitive files.
