Companies House WebFiling security issue – what you should know:
• Companies House recently temporarily suspended its WebFiling service after a technical security issue was identified.
• The issue meant it may have been possible for someone to view or potentially change certain company information without proper authorisation.
• Companies House took the system offline while the issue was investigated and security measures were reviewed.
• The WebFiling service has now been restored.
• Companies House are continuing to investigate the issue and have reported it to the relevant authorities.
• As a precaution, company directors may wish to check their company record to ensure that no unauthorised changes have been made.
• If anything looks incorrect on your company record, it should be reported to Companies House as soon as possible.
