Incident Details

In August 2020, Experian South Africa disclosed that a suspected fraudster had obtained personal data of approximately 24 million South African individuals and 793,749 businesses by fraudulently impersonating a legitimate Experian client and requesting a data dataset. The Southern African Fraud Prevention Service (SAFPS) assisted with the investigation. The exposed data included consumer contact and employment information used for credit and insurance risk assessments β€” but Experian stated it did not include financial information or credit records. The data appeared on a hacker forum in late 2020. South Africa’s Information Regulator investigated under the Protection of Personal Information Act (POPIA). A suspect was identified and Experian obtained a court order to delete the data from the suspect’s devices; the suspect’s devices were surrendered and a high court order was granted. The incident highlighted the risks of social engineering at credit bureaus and the vulnerabilities inherent in business-to-business data sharing arrangements.
