MTN Group, Africa’s largest telecommunications provider, has experienced a significant cybersecurity breach in April. The incident, which led to unauthorised access to the personal information of customers in more than one market, is the latest in a series of cyber incidents at major companies across the country.
Despite the breach, MTN confirmed that its core infrastructure, including network, billing, and financial systems, remained secure and fully operational. Here are the full details of the breach and what businesses can learn from MTN’s response.
How the Breach Happened
Though MTN is a household name in SA, the cyberattack actually resulted in the compromise of customer data beyond our borders, with approximately 5 700 MTN Ghana customers being affected.
An unknown third party claimed responsibility for the breach and demanded a ransom for the release of the stolen data – a classic MO for cyberattacks of this kind.
At the time of publishing this update MTN had not disclosed the ransom amount, citing the ongoing investigation, and has also neither confirmed nor denied that paying the ransom is a strategy currently under consideration.
Did MTN Respond Appropriately?
MTN’s reaction in the hours and days following this attack is a good example of proactive cybersecurity response and the benefits of risk mitigation.
- After discovering the breach, MTN activated its cybersecurity response protocols and altered law enforcement agencies such as the South African Police Service (SAPS) and the Hawks.
- This is the recommended course of action for any business dealing with a major cyber incident.
- The company also notified relevant authorities in affected countries and is in the process of informing impacted customers, adhering to local legal and regulatory requirements. As above, this is the approach favoured by cybersecurity experts: placing customer privacy and data first.
MTN joins a long list of prominent cybersecurity victims across the country
This incident is not the first of its kind, nor will it be the last, but it once again highlights the growing threat of ransomware attacks in the telecommunications sector.
Earlier in 2025, Cell C, confirmed a data breach linked to a ransomware attack by the RansomHouse group. Unlike the anonymous MTN incident, this attack was carried out by a notorious cybercrime network with the intention of adding Cell C to their list of high profile victims.
The ripple effects of cyberattacks have againbextended beyond telecoms to other essential services, including the travel industry. In May, South African Airways (SAA) suffered a major cyber incident that disrupted access to its website, mobile app, and key operational systems. The breach, which began over a weekend, significantly impacted customer services and internal processes, highlighting the broad-reaching consequences of digital vulnerabilities across sectors.
Whether hackers strike stealthily or make a show of their ability to penetrate digital defences, the increasing frequency of attacks like these underscores the need for robust cybersecurity measures across the industry and the economy as a whole.
