Cyber attacks 2

Request for information - FOI17776


Thank you for your email of 13 June 2017, in which you narrowed the scope of your original request (FOI17764), and your additional email of 14 June 2017, clarifying your request.

Original FOI request of 9 May 2017 (FOI17764):
I would like to make a request under the Freedom of Information Act 2000 relating to cyber attacks on your organisation.

To be clear, by "cyber attack" I am referring to the unauthorised external access or deliberate disruption of a computer system or a device owned and/or operated by your organisation. Types of cyber attack could include, but are not limited to: ransomware, denial of service, phishing and spear phishing.

By data, I refer to any information held on your computer systems or devices.

Please could you answer the following:-

1) Does your organisation keep an incident log of cyber attacks?
2) How many cyber attacks - attempted and successful - were recorded against your organisation in the last three financial years (ie 2014/15, 2015/16, 2016/17)?
3) Where cyber attacks were successful, what kind and amount of data, if any, was lost or stolen? Was it confidential?

For each case, please confirm:

4) The type of attack (eg ransomware, denial of service etc)
5) What demand, for example a Bitcoin payment, was made to resolve the attack? Did your organisation comply?
6) Whether the attack was reported to police or other responsible authority? To the best of your knowledge, was the attacker traced/convicted?

If possible, please provide this information in Excel spreadsheet format.

Email of 13 June 2017:
Thank you for your reply. I understand the restriction imposed by Section 12. Would it bring this request within the time limit if I restricted it to just the last financial year - ie March 2016 to April 2017?

If that does come within the time limit please treat this as a modified request on those lines.

Email of 14 June 2017:
Thanks for your reply. I would classify a successful cyber attack as an incident in which IT firewalls were breached and/or data held by OS was in any way compromised, for example by encryption or direct theft.

I'm not asking for information on attempted attacks in the sense that I imagine OS, in common with almost any organisation including my own, receives many attempted malicious emails almost daily but they are stopped by firewalls and other normal preventive measures.

Our response

I confirm that Ordnance Survey does hold the information you have requested. I am pleased to provide you with the attached details on cyber attacks (xlsx) which provides information on cyber attacks (in which IT firewalls were breached and/or data held by Ordnance Survey was in any way compromised) from March 2016 to April 2017, in relation to questions 2 to 6 of your original request (FOI77764). Please note we have provided the information for question 1 in our response to your original request (FOI17764) of 7 June 2017.
