Abstract

Techniques and devices for circumventing wireless data monitoring in communications between a communication device and a proxy server, as well as systems and techniques for detecting and resolving vulnerabilities in wireless data monitoring systems are described herein. The techniques for circumventing wireless data monitoring may include manipulating a routing table of a communication device, encapsulating data in an unmonitored protocol, and transmitting the encapsulated data in a “bearer,” or communications channel, to a proxy server that fulfills requests included in the encapsulated data. Furthermore, the techniques for detecting and resolving network vulnerabilities may include restricting protocols by bearers in an Access Control List, limiting a bandwidth of a bearer, or protecting a routing table in a secure location of the communication device.

Claims (63)

1. A system comprising:

a communication device including a first memory coupled to a first processor, the first memory including one or more modules that are executable by the first processor to perform first operations comprising:

gaining root access to the communication device;

updating a routing table stored in the first memory of the communication device, the routing table identifying at least a first destination and a first communication bearer;

encapsulating a hypertext transfer protocol (HTTP) request from an application stored in the first memory as an Internet Control Message Protocol (ICMP) packet;

transmitting the ICMP packet to a proxy server via the first communication bearer based at least in part on the routing table;

receiving an ICMP reply packet from the proxy server;

identifying a network vulnerability based at least on part on the ICMP reply packet; and

providing an indication to a service provider of the network vulnerability,

wherein identifying a network vulnerability based at least on part on the ICMP reply packet comprises:

determining that the ICMP reply packet was received from a proxy server at the communication device; and

determining the proxy server is outside of the service provider's network.

2. The system of claim 1 , wherein identifying a network vulnerability based at least on part on the ICMP reply packet comprises:

determining that the ICMP reply packet includes data fetched by a proxy server; and

determining that the ICMP reply packet transfer was undetected by the network.

3. The system of claim 2 , wherein determining that the ICMP replay packet transfer was undetected by the network comprises:

determining that the ICMP reply packet is a type of data or protocol that is ignored or not logged by the network.

4. The system of claim 1 , further comprising a data server associated with the service provider, the data server comprising a third memory coupled to a third processor, the third memory including one or more modules that are executable by the third processor to perform third operations comprising:

receiving the indication of the network vulnerability; and

updating an access control list to block the ICMP packet from being delivered to the proxy server.

5. The system of claim 1 , further comprising a data server associated with the service provider, the data server comprising a third memory coupled to a third processor, the third memory including one or more modules that are executable by the third processor to perform third operations comprising:

receiving the indication of the network vulnerability;

determining that the ICMP reply packet was received at the communication device from a voice over long term evolution (VoLTE) communication bearer; and

restricting a bandwidth of the VoLTE communication bearer.

6. A computer-implemented method comprising:

gaining root access to a communication device associated with a service provider of a network;

updating a routing table of the communication device to identify at least a first destination and a first communication bearer, wherein the first destination is a destination unauthorized by the service provider;

encapsulating data as an encapsulated data packet;

transmitting the encapsulated data packet to a proxy server via the first communication bearer based at least in part on the routing table;

determining whether the encapsulated data packet can be transmitted to the first destination; and

receiving an encapsulated reply data packet from the proxy server at the communication device,

wherein determining whether the encapsulated data can be transmitted to the first destination comprises:

determining that the encapsulated data can be transmitted to the first destination based at least in part on the receiving of the encapsulated reply data packet; and

providing an indication to a service provider of a network vulnerability.

7. The method of claim 6 , wherein determining whether the encapsulated data can be transmitted to the first destination comprises determining that the encapsulated data cannot be transmitted to the first destination, the method further comprising:

providing an indication to the service provider that undetected data transfer is not possible.

8. The method of claim 6 , wherein the encapsulated reply data packet includes at least web content fetched by the proxy server.

9. The method of claim 6 , further comprising:

storing the routing table in a trusted execution environment of the communication device in response to determining that the encapsulated data can be transmitted to the first destination.

10. The method of claim 6 , further comprising:

determining that the proxy server is a dedicated communication bearer providing Voice over Long Term Evolution (VoLTE) voice communications; and

restricting a bandwidth of the dedicated communication bearer.

11. The method of claim 6 , wherein the transmitting the encapsulated data packet is not logged in a data volume associated with a data monitoring module associated with the network.

12. The method of claim 6 , wherein encapsulating the data as the encapsulated data packet comprises encapsulating a hypertext transfer protocol (HTTP) request as an Internet Control Message Protocol (ICMP) packet.

13. A communication device operating on a network associated with a service provider, the communication device comprising:

a processor, and

a memory including one or more modules that are executable by the processor to perform operations comprising:

updating a routing table stored in the memory to identify at least a first destination and a first communication bearer, wherein the first communication bearer is unauthorized for use by the service provider;

encapsulating a first data as a first encapsulated data packet;

transmitting the first encapsulated data packet via the first communication bearer to the first destination based at least in part on the routing table;

receiving a first encapsulated reply data packet, the first encapsulated reply data packet including content provided by a network component at the first destination;

providing an indication to the service provider of a network vulnerability based at least in part on the receiving the first encapsulated reply data packet;

updating the routing table stored in the memory to identify at least the first destination and a second communication bearer;

encapsulating a second data as a second encapsulated data packet;

transmitting the second encapsulated data packet via the second communication bearer to the first destination based at least in part on the routing table; and

receiving a second encapsulated reply data packet, the second encapsulated reply data packet including content provided by the network component at the first destination.

14. The communication device of claim 13 , wherein the encapsulating the first data as the first encapsulated data packet comprises encapsulating a hypertext transfer protocol (HTTP) request as an Internet Control Message Protocol (ICMP) packet.

15. The communication device of claim 13 , wherein the operations further comprise:

storing the routing table in a trusted execution environment of the communication device in response to receiving the first encapsulated reply data packet.

16. The communication device of claim 13 , the operations further comprising:

determining a quality of service (QoS) for the first communication bearer and the second communication bearer based at least in part on the first encapsulated reply data packet and the second encapsulated reply data packet; and

providing an indication to the service provider of a QoS for the first communication bearer, the second communication bearer, or both the first communication bearer and the second communication bearer based at least in part on the receiving the first encapsulated reply data packet and the second encapsulated reply data packet.

17. The communication device of claim 13 , wherein the first encapsulated data packet is sent with a first QoS class identifier (QCI) and the second encapsulated data packet is sent with a second QCI.
