Cyberlockers explained: how file hosts end up serving pirated copies
A cyberlocker is a place to store a file and share it by link. That is all a pirate needs.
In short: a cyberlocker (or one-click file host) stores an uploaded file and gives back a download or streaming link. Most uses are legitimate, but the same model makes it easy to share a full copy of a film, album or game with anyone who has the link.
This post explains how the pieces fit together, and what that means for removing a copy.
How a file host is used
The uploader does not publish the file anywhere public on the host itself. Instead, the link is posted elsewhere: on a link site, in a forum thread, in a comment or in a messaging channel.
- The host stores the file and serves it to whoever opens the link.
- The link site lists titles and points visitors to the host.
- The uploader often posts the same file to several hosts so one removal does not break every link.
Two problems, not one
Removing the link from a link site leaves the file online. Removing the file from the host breaks the link everywhere it was posted, but only for that copy.
That is why monitoring has to follow the link to the host, and why notices usually go to both parties.
What helps
- Checking where each link actually resolves, rather than stopping at the page that lists it.
- Grouping mirror uploads of the same file so they are reported together.
- Re-checking hosts after removal, because the same file is often uploaded again under a new name.
