Abstract

Systems, methods, and computer readable media for detecting and mitigating address spoofing in messaging service transactions are disclosed. A messaging service firewall (MSF) separate from a short message service center (SMSC) receives a mobility management reply message (MMR) that is sent by a mobile location register element in response to an associated mobility management query (MMQ) and that includes a serving switch identifier. The MSF allocates a global title address (GTA) from a pool of GTAs and stores a correlation between the allocated GTA and the originating SMSC. The MSF replaces the serving switch identifier in the MMR with the allocated GTA and routes the modified MMR. The MSF then receives a messaging service message (MSM) that is addressed to the allocated GTA and that includes the purported originating SMSC. If the purported originating SMSC does not match the SMSC to which the GTA is correlated, the MSM is discarded.

Claims

1. A method for detecting and mitigating address spoofing in a messaging service transaction, the method comprising:

at a messaging service firewall separate from a short message service center (SMSC) and implemented on a platform including at least one processor;

receiving a mobility management reply message that is sent by a mobile location register element in response to an associated mobility management query, the mobility management query and the mobility management reply message being associated with a mobility management transaction, the mobility management reply message including a message service recipient identifier and a serving switch identifier;

allocating a global title address (GTA) from a pool of global title addresses within a range of global title addresses assigned to the firewall;

storing a correlation between the allocated GTA and an originating SMSC identifier;

replacing the serving switch identifier in the mobility management reply message with the allocated GTA;

routing the modified mobility management reply message;

receiving a message service message associated with the mobility management transaction, the messaging service message being addressed to the allocated GTA;

determining the originating SMSC identifier to which the allocated GTA is correlated;

comparing SMSC identifier information extracted from the messaging service message with the originating SMSC identifier to which the allocated GTA is correlated to determine if the messaging service message contains spoofed address information; and

in response to determining that the messaging service message contains spoofed address information, discarding the messaging service message.

2. The method of claim 1 comprising generating a message detail record based on the attempted delivery of the message service message.

3. A method for detecting and mitigating address spoofing in a messaging service transaction, the method comprising:

at a messaging service firewall separate from a short message service center (SMSC) and implemented on a platform including at least one processor;

receiving a mobility management query message associated with a message delivery transaction that is sent by an originating SMSC element, where the mobility management query message includes a message service recipient identifier and a first originating SMSC identifier;

generating a mobility management reply message in response to the query message, the reply message including a least a portion of the first originating SMSC identifier in one or more parameters of the reply message that trigger the originating SMSC to echo the parameters in a subsequent message associated with the message delivery transaction;

receiving a messaging service message associated with the message delivery transaction, where the messaging service message includes the echoed parameters;

extracting the echoed parameters from the messaging service message;

comparing SMSC identifier information extracted from the messaging service message with SMSC identifier information contained in the routing label of the received messaging service message to determine if the messaging service message contains spoofed address information; and

in response to determining that the messaging service message contains spoofed address information, discarding the messaging service message.

4. The method of claim 3 comprising generating a message detail record based on the attempted delivery of the message service message.

5. The method of claim 3 wherein receiving the messaging service message associated with the message delivery transaction comprises receiving the messaging service message from a signaling message routing node that uses mobile application part (MAP) screening to route received messaging service messages.

6. A system for detecting and mitigating address spoofing in messaging service transactions, the system comprising:

a messaging service firewall separate from a short message service center (SMSC) and implemented on a platform including at least one processor, the messaging service firewall including;

a network interface for sending and receiving signaling messages; and

a spoofing detection module for;

receiving, from the network interface, a mobility management reply message that is sent by a mobile location register element in response to an associated mobility management query, where the mobility management reply message includes a message service recipient identifier and a serving switch identifier;

allocating a global title address (GTA) from a pool of global title addresses within a range of global title addresses assigned to the firewall;

generating and storing a correlation record that associates the GTA with an originating SMSC identifier;

replacing the serving switch identifier in the reply message with the firewall GTA;

routing the modified reply message;

receiving, from the network interface, a message service message including the allocated GTA and using the allocated GTA to locate the correlation record;

comparing SMSC identifier information extracted from the messaging service message with SMSC identifier information contained in the correlation record to determine if the messaging service message contains spoofed address information; and

in response to determining that the messaging service message contains spoofed address information, discarding the messaging service message.

7. The system of claim 6 wherein the messaging service firewall generates a message detail record based on the attempted delivery of the message service message.

8. A system for detecting and mitigating address spoofing in messaging service transactions, the system comprising:

a messaging service firewall separate from a short message service center (SMSC) and implemented on a platform including at least one processor, the messaging service firewall including;

a network interface for sending and receiving signaling messages; and

a spoofing detection module for;

receiving, from the network interface, a mobility management query message associated with a message delivery transaction that is sent by an originating SMSC element, where the mobility management query message includes a message service recipient identifier and a first originating SMSC identifier;

generating a mobility management reply message, in response to the query message, that includes a least a portion of the first originating SMSC identifier in one or more parameters of the reply message that trigger the originating SMSC to echo the parameters in a subsequent message associated with the message delivery transaction;

receiving, from the network interface, a messaging service message associated with the message delivery transaction, where the messaging service message includes the echoed parameters;

extracting the echoed parameters in the messaging service message;

comparing SMSC identifier information extracted from the messaging service message with SMSC identifier information contained in the routing label of the received messaging service message to determine if the messaging service message contains spoofed address information; and

in response to determining that the messaging service message contains spoofed address information, discarding the messaging service message.

9. The system of claim 8 wherein the messaging service firewall generates a message detail record based on the attempted delivery of the message service message.

10. The system of claim 8 comprising a signaling message routing node that uses mobile application part (MAP) screening to route messaging service messages to the messaging service firewall.

11. A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:

at a messaging service firewall separate from a short message service center (SMSC) and implemented on a platform including at least one processor;

receiving a mobility management reply message that is sent by a mobile location register element in response to an associated mobility management query, where the mobility management reply message includes a message service recipient identifier and a serving switch identifier;
