The UK's internet watchdog, Ofcom, has launched a new enforcement programme under the Online Safety Act (OSA), targeting storage and file-sharing services due to concerns over the sharing of child sexual abuse material (CSAM).

The regulator has identified these services as particularly vulnerable to misuse for distributing CSAM and will assess the safety measures in place to prevent such activities.

As part of the enforcement programme, Ofcom has contacted a number of file-storage and sharing services, warning them that formal information requests will be issued soon.

These requests will require the services to submit details on the measures they have implemented or plan to introduce to combat CSAM, along with risk assessments related to illegal content.

Failure to comply with the requirements of the OSA could result in substantial penalties for these companies, with fines reaching up to 10% of their global annual turnover.

Ofcom's crackdown highlights the growing responsibility for online services to prevent illegal content from being shared on their platforms.
