Can a legitimate website contain criminal content?¶

Yes. Material can appear within an otherwise legitimate service without the whole organisation creating, approving or even knowing about it.

Identify the content boundary¶

The material may be user-generated content, a seller listing, an uploaded file, a third-party advertisement or an embedded resource. It may also be a hidden page inserted after compromise. Those routes create different records and point to different responsible accounts.

For example, a marketplace supplies the overall website while individual sellers control their listings. An advertising network can select material shown inside a page. A vulnerable plugin may allow an attacker to add files without using the ordinary publishing interface.

This is similar to unlawful material being placed on a public noticeboard: the owner of the building, operator of the board and person who posted the item are separate questions.

Record the exact URL and content location. Determine whether the material came from the site’s own domain or another service. Platform moderation records, user-account activity, content history, file timestamps, security alerts and administrator logs can help explain how it appeared.

The organisation’s response may also matter: when it became aware, what access was identified and what preservation or incident work followed.
