South Africa’s banks are on high alert as their servers may be vulnerable to cyber attacks.

The global warning was sounded on December 9, when reports of a vulnerability in Java software had been picked up.

The Log4Shell software can allow someone to take control of Java-based web servers.

It also makes them susceptible to remote attacks on banks and other institutions.

The South African Banking Risk Information Centre (SABRIC) says that they’re monitoring the situation.

However, the country’s four major banks have not yet reported any breaches of their security.
