Section 3A of the Computer Misuse Act 1990 makes it an offence to supply
or obtain articles for use in offences under section 1 (unauthorised access
to computer material) or section 3 (unauthorised actions with intent to impair,
or with recklessness as to impairing, operation of computer etc.). For the
purposes of section 3A an article or tool could include a ‘botnet’. We keep
the Computer Misuse Act 1990 under constant review.
