In previous incidents, RansomHouse has claimed responsibility for attacks on major organizations, including chip manufacturer Advanced Micro Devices (AMD), supermarket chain Shoprite Group and the Saskatchewan Liquor and Gaming Authority. South Africa’s fourth-largest mobile network operator, Cell C, has confirmed that its data was leaked on the dark web following a cyberattack last year. In a statement issued Wednesday, the company said that the data disclosed by RansomHouse included a range of personal and sensitive information. The company is urging affected individuals to take precautions against phishing and potential identity theft now that the data has been published by the attackers. Among the types of compromised data were full names, contact details, ID numbers, banking information, driver’s license numbers, medical records and passport details. The hacker group responsible for the attack, RansomHouse, claimed to have breached 2TB of the company’s data. Cell C, a mobile telecommunications company operating in South Africa, has fallen victim to RansomHouse ransomware. The company has also set up monitoring systems to track the potential misuse of the leaked data. Cell C said it is working with international cybersecurity and forensic experts, cooperating with relevant authorities and working closely with stakeholders to provide guidance and findings. Rather than encrypting data, the group threatens to release all exfiltrated information publicly. “We understand the seriousness of this development and deeply regret the distress or concern it may cause,” said Cell C CEO Jorge Mendes in a letter to customers. Cell C, which serves 7.7 million subscribers, did not disclose whether a ransom was demanded or if negotiations took place with the attackers. RansomHouse, a cybercrime group that emerged in March 2022, is known for its extortion tactics. The group claims to have obtained 2 TB of the organization's data.
