Abstract
In one example, a firewall obtains a first network packet that indicates a first mobile country code of a mobile subscriber at a first time and a first mobile network code of the mobile subscriber at the first time. The firewall obtains a second network packet that indicates a second mobile country code of the mobile subscriber at a second time and a second mobile network code of the mobile subscriber at the second time. The firewall determines whether the first mobile country code is different from the second mobile country code or the first mobile network code is different from the second mobile network code. If so, the firewall determines whether a difference between the second time and the first time is less than a threshold difference. If so, the firewall associates the second network packet with a potential security threat.
