City of Joburg systems are expected to be back online by the end of the weekend, following a cyber attack.
The City on Thursday night announced a breach of its network on and shut down its website and all e-services as a precautionary measure. In a tweet, the City said it had detected a network breach "which resulted in an unauthorised access to our information systems".
Business Day reported that the attack came hours after the City received a bitcoin ransom note from a group called the Shadow Kill Hackers.
The City further tweeted: "The incident is currently being investigated by City of Joburg cyber security experts, who have taken immediate and appropriate action to reinforce security measures to mitigate any potential impacts.”
Several customer-facing systems, including the City's website, e-services and billing system were shut down as a precautionary measure. The City said the shutdown would last for 24 hours.
