Gabreil Makhlouf, Treasury secretary and CEO, said the Treasury has "gathered sufficient evidence to indicate that its systems have been deliberately and systematically hacked."
The Treasury has referred the matter to the Police on the advice of the National Cyber Security Centre.
Media reports this morning indicate more than 2,000 attempts were made to hack Treasury's website starting on Sunday night.

"It has taken immediate steps today to increase the security of all Budget-related information and will be undertaking a full review of information security processes.

It is not known whether the alleged hacking attempt was successful or what it achieved or was trying to achieve.
