As a precautionary measure, we wish to inform you that your Twitter account is one of a small group of accounts that may be the target of an attack by state sponsored agents. We think that these agents (who may be associated with the government) are seeking to obtain emails, IP addresses, and/or telephone numbers.
At the moment, we don't have proof that they have access to your account details, but we are actively pursuing our enquiries. We hope to have more details to give you, but we are not at present able to provide more information.
It's possible that your account has not been specifically targeted by these suspicious activities but we hope to tell you more as soon as possible. We are conscious that this situation could have particular importance if you tweet using a pseudonym. If you would like advice concerning the protection of your identity on the internet, these pages ... will be of particular interest to you.
