Ofcom updates enforcement programme on CSAM risks in file-sharing services

The Office of Communications (Ofcom) has updated its enforcement programme launched on 17 March 2025 to assess measures taken by file-sharing and file-storage services to prevent risks to UK users from image-based child sexual abuse material (CSAM). The update follows its previous report in February 2026.

Ofcom said it identified concerns after two services under investigation redirected users to another file-sharing platform, Pixeldrain. Following further assessment, the regulator found that the provider had not initially taken appropriate measures to manage risks linked to CSAM storage and dissemination.

Following engagement with Ofcom, the provider of Pixeldrain updated its Illegal Content Risk Assessment and reassessed the level of risk on its service. The company also implemented perceptual hash matching to reduce the risk of known CSAM being shared. Ofcom stated that, due to these improvements and constructive engagement, no further action will be taken at this stage.

Ofcom’s investigation into Im.ge remains ongoing, focusing on compliance with risk assessment and user protection duties under the Online Safety Act 2023. Separately, the regulator has closed its investigation into Yolobit after the service became unavailable to UK users, reducing exposure risks.
