A major hack that compromised Uganda’s mobile money network has plunged the country’s telecoms and banking sectors into crisis.

The Oct. 3 hack was a result of a security breach on a consumer finance aggregator, Pegasus Technologies, which mainly affected bank to mobile wallet transfers, according to an Oct. 8 statement by MTN Uganda, the country’s largest mobile phone company. Kampala-based Pegasus Technologies  provides financial and billing solutions for various companies including all the affected entities.
