The companies – TransUnion and Experian – were the ones that were hit by the cybercrime attack. 

According to Times Live, the hackers, the Brazil-based N4ughtySecTU Group, who had previously breached TransUnion's security and firewalls, claimed to have successfully evaded the safeguards of the company once again, following which they stole the data.  

Apparently, the hackers have demanded $30m [about R565m] from TransUnion and $30m from Experian.

The hackers, in a message sent to the managers and directors of the impacted companies, stated: “Ensure your response teams contact us on Session [a private communication platform] for payment instructions.”

While acknowledging the demands, TransUnion and Experian refuted the group's allegations of an ongoing hack on their systems.

“Following recent media coverage, TransUnion South Africa confirms it is aware of a financial demand from a threat actor asserting they have accessed TransUnion South Africa’s data. We have found no evidence that our systems have been inappropriately accessed or that any data has been exfiltrated,” TransUnion said.

“We’ve likewise seen no change to our operations and systems in South Africa related in any way to this claim. We are continuing to monitor closely. We treat matters regarding our information security seriously, and data security remains our top priority,” they continued. 

Not the First Attempt to Hack

Previously, in March 2022, N4ughtysecTU claimed responsibility for targeting TransUnion in their ransomware campaign. 

TransUnion South Africa later confirmed the hack, confirming that at least 3 million individuals were affected.  

Apparently, the threat actors gained access to the personal data of over 54 million people, which included information about their dates of birth, ID numbers, gender, marital status, and other sensitive facts. 

Experian also suffered a data breach in August 2020, reported by the South African Banking Risk Centre (SABRIC). The data breach compromised the personal information of around 24 million individuals and several business entities to a fraudster. 

Karabo Phungula, an Experian data fraudster, was given a 15-year prison sentence in March by the Specialized Commercial Crimes Court for obtaining the dataset under false pretence.
