Zimbabwe is to speed up finalisation of its cyber-crimes Bill following the global WannaCry ransomware attacks this month, according to the country's ICT Minister Supa Mandiwanzira.

WannaCry spread across global networks as hackers took control of computers and systems.

More attacks are now expected, experts said this week, prompting governments such as Zambia, Zimbabwe and others in Africa to scramble to action.

"Zimbabwe was not affected but all organisations have to be vigilant in updating software and operating systems and we will continue to raise awareness among users. The ministry will speed up the cyber-crimes bill," Mandiwanzira said.

The Minister said the outbreak had helped Zimbabwe "wake up to the realities of the dangers in the cyberspace" hence the need for the computer and cyber-crimes law "to protect" telecommunications and other tech consumers.

There have been concerns from experts, opposition political parties and non-governmental organisations championing freedom of expression, that the government is spearheading the law to snoop on private and political communications by opposition parties.

The Zimbabwean cyber-crime law, when passed, will also seek to prosecute offenders for spreading or possessing offensive or improper social media and online content.

It adds that such offender will be "liable on conviction to a fine not exceeding level 10 or imprisonment not exceeding five years" or both.
