Vendor MTN Group Confirms Approximately 5,700 Customers in Ghana May Be Impacted
MTN Suffers Cybersecurity Incident: A Detailed Look at the Response
In a significant development, MTN Group, a leading telecommunications company, has disclosed a cybersecurity incident that occurred in early 2025. The breach, discovered on Valentine's Day (February 14, 2025), led to unauthorized access to MTN's networks, with an unknown extent of data potentially stolen or compromised.
In response to the incident, MTN has taken immediate action. The company activated emergency response plans, disconnected affected IT systems to contain the breach, and notified relevant authorities. A detailed forensic analysis is currently underway to assess data loss, damage, and vulnerabilities exploited by the attackers. MTN continues to cooperate with law enforcement and cybersecurity experts to mitigate further risks.
The confidentiality, integrity, and availability of MTN's systems are crucial to its operations. Despite the incident, all platforms of MTN Group remain fully operational.
MTN is urging customers to stay vigilant and take several precautions to protect their data. Activating multi-factor authentication where possible is suggested. Customers are also encouraged to keep MTN, MoMo, and banking apps updated. It is advisable to place a fraud alert on credit reports with major bureaus.
Customers are urged to be cautious of suspicious links and unexpected messages. MTN advises against disclosing passwords, PINs, or OTPs via phone, text, or email. If customers suspect any unauthorized activity, they can contact MTN's toll-free customer care line for support (100).
Early findings suggest about 5,700 MTN Ghana customers may have had their data affected. Using strong, unique passwords and changing them regularly is recommended.
It is important to note that this incident forms part of a broader pattern where South African telecom companies, including MTN and Cell C, have faced cybersecurity incidents in 2025. Telecommunication infrastructures are increasingly targeted due to the large volumes of sensitive customer and operational data they hold.
Besides the cyberattack, MTN Group is under investigation by U.S. authorities for issues concerning its operations in Iran and Afghanistan, including allegations of misconduct and lawsuits unrelated directly to the cybersecurity breach but relevant to the company's overall regulatory and security posture.
In summary, MTN Group's cybersecurity incident involved network intrusions discovered in February 2025. The company responded promptly by isolating affected systems and launching an investigation, with ongoing efforts focused on containment and understanding the breach's full impact. Customers are encouraged to follow the recommended precautions to protect their data during this time.
