Methods, systems, and computer program products for detecting fraudulent message service message traffic are disclosed. According to one method, message service messages are monitored. It is determined that the message service message traffic indicates that the message service message traffic is fraudulent based on detection of at least one of: 1) message service message traffic received at a first network from a second network, where the traffic includes at least one message with an SCCP calling party address internal to the first network, 2) a volume of message service message traffic received at the first network from the second network that exceeds the volume of message service message traffic sent by the first network to the second network by a threshold amount, and 3) message service message traffic that is sent to a dark number. In response to detecting fraudulent message service message traffic, a mitigating action is performed.
