Mtn Group Hit By 'cybersecurity Incident'

In the disclosure, which came late on Thursday evening, MTN said it has found no evidence that any of its critical infrastructure has been compromised. Neither have MTN's core platforms or services been compromised.

"Our core network, billing systems and financial services infrastructure remain secure and fully operational," it said.

"An unknown third-party has claimed to have accessed data linked to parts of our systems. At this stage we do not have any information to suggest that customers' accounts and wallets have been directly compromised."

MTN said it has informed the South African Police Service and the Hawks about the incident and will do the same with similar law enforcement authorities in other affected markets. It didnt say which markets had been affected, though given the involvement of local police, it appears likely that the South African operation is one of those impacted.
