The South African Banking Risk Information Centre (Sabric) has warned that local banks are under sustained distributed denial-of-service (DDoS) attacks, targeting “various public-facing services”.
The attacks began on Wednesday, 23 October, Sabric said in a statement.
“These attacks started with a ransom note that was delivered via e-mail to both unattended as well as staff e-mail addresses, all of which were publicly available,” the organisation said.
“Threat intelligence which has surfaced has revealed that this is a multi-jurisdictional attack with entities from several countries being targeted and should therefore not be viewed as a targeted attack on South African companies only,” Sabric said.
“We must emphasise that DDoS attacks like this one do not involve hacking or a data breach and therefore no customer data is at risk. It does, however, involve increased traffic on networks necessary to access public-facing services. This may cause minor disruptions.”
South Africa has the third-highest number of cyber-crime victims worldwide, losing about R2.2 billion a year to cyber-attacks.
