Insurer Liberty Holdings faced questions from South Africa’s Information Regulator, days after the company said it had become the victim of a cyber-attack.
The regulator said it was concerned about the data breach and wanted to meet the insurer to get more details.
Liberty’s shares fell 5 percent on Monday, after the company said on Sunday that an external party claimed to have seized data from the firm and demanded payment.
Liberty said it made no concessions to the hackers and that there was no evidence that any of its customers had suffered any financial losses.
On Monday it said its IT specialists and security personnel had worked around the clock to ensure the protection of its customers and their details.
The regulator said it had written to Liberty’s Chief Executive David Munro requesting information on the extent of the data breach and security measures taken by the company.
“The Information Regulator has noted with concern various media reports regarding a material data breach at Liberty Holdings,” Pansy Tlakula, chairwoman of the regulator, said in a statement.
