. It claims that 75% of files uploaded are not distributed to multi-scanners, Inclusive of the file's associated vendors. This obviously leaves 25% of files actually distributed, hence the (site's) name does not live up to It's service.

Three-quarters of malware samples uploaded to "no-distribute scanners" are never shared on "multiscanners" like VirusTotal, and hence, they remain unknown to security firms and researchers for longer periods of time.

Although some antivirus products will eventually detect this malware at runtime or at one point or another later in time, this leaves a gap in terms of operational insight for security firms hunting down up-and-coming malware campaigns.

A no-distribute scanner is a service similar to a multiscanner, only that its operators modify the AV engines so they cannot report back to their respective vendors, hence limiting their ability to see the malware uploaded on such a service.

As you would imagine, no-distribute scanners are quite in demand on the cyber-criminal underground, and they have been in demand for years, with several services appearing and disappearing across the years, some going down on their own, while others after law enforcement intervention.
