When accessing their bills online, MTN clients are being shown the bills of other subscribers.
This is according to a subscriber who told MyBroadband he was able to see thousands of bills that weren’t his own.
He logged in as normal on MTN’s e-billing site, received a one-time PIN, and accessed the client portal – which looked the same as it always does.
However, when he tried to download his invoice, he was shown the names, numbers, and bills of other customers.
To find his bill, he had to use the browser’s search feature to look for his number – wading through the bills of other subscribers which contained personal information.
MTN was asked for comment on the data leak, but the company did not respond by the time of publication.
Update: MTN’s Twitter account has retweeted an apology to customers regarding its online billing system, which it said has been deactivated until the security issue has been resolved.
