Abstract

Claims (34)

1. A method for monitoring an electronic device to detect infection by unwanted software, the method comprising:

receiving parameters and inserting the parameters into artificial sensitive information using a software agent running on the electronic device, wherein the parameters include identifying information for the electronic device;

performing, using the software agent running on the electronic device, a login session using the artificial sensitive information; and

monitoring, at a computer hardware network gateway, network transmissions of the electronic device unrelated to the login session to detect a transmission of the artificial sensitive information to another electronic device based on a comparison of information included in a network transmission to the artificial sensitive information to determine the existence of unwanted software on the electronic device based on the information identifying the electronic device being included in the transmission of the artificial sensitive information.

2. The method of claim 1 , further comprising installing the software agent on the electronic device.

3. The method of claim 1 , further comprising performing, using the software agent, the login session by emulating keystrokes on the electronic device.

4. The method of claim 3 , further comprising emulating the keystrokes, using the software agent, at a variable rate.

5. The method of claim 1 , further comprising:

detecting encrypted electronic output of the electronic device within the network transmissions of the electronic device;

correlating an amount of the encrypted electronic output with one or more properties of the artificial sensitive information; and

determining that the network transmissions of the electronic device include the transmission of the artificial sensitive information based on the correlating.

6. The method of claim 5 , further comprising detecting the encrypted electronic output based on an entropy of the network transmissions of the electronic device.

7. The method of claim 1 , wherein the electronic output is analyzed by correlating the output with the artificial sensitive information.

8. The method of claim 1 , further comprising:

storing information about the artificial sensitive information in a database; and

comparing information from a user with the information in the database in order to determine if the electronic device that transmitted the artificial sensitive information contains unwanted software.

9. The method of claim 1 , wherein the software agent performs the login session on a target site, the method further comprising:

configuring the artificial sensitive information to identify the electronic device; and

monitoring the target site for detection of the artificial sensitive information to determine the existence of unwanted software on the electronic device.

10. A system for monitoring an electronic device to detect infection by unwanted software, the system comprising:

a software agent installed on the electronic device and configured to:

receive parameters and insert the parameters into artificial sensitive information, wherein the parameters include identifying information for the electronic device, and

perform a login session using the artificial sensitive information; and

a computer hardware network gateway configured to monitor network transmissions of the electronic device unrelated to the login session that include a transmission of the artificial sensitive information over a network to another electronic device to determine the existence of unwanted software on the electronic device based on the information identifying the electronic device being included in the transmission of the artificial sensitive information.

11. The system of claim 10 , further comprising a management unit configured to install the software agent on the electronic device.

12. The system of claim 10 , wherein the software agent is configured to perform the login session by emulating keystrokes on the electronic device.

13. The system of claim 12 , wherein the software agent is further configured to emulate the keystrokes at a variable rate.

14. The system of claim 10 , wherein the computer hardware network gateway is further configured to:

detect encrypted electronic output of the electronic device within the network transmissions of the electronic device;

correlate an amount of the encrypted electronic output with one or more properties of the artificial sensitive information; and

determine that the network transmissions of the electronic device include the transmission of the artificial sensitive information based on the correlating.

15. The system of claim 10 , wherein the computer hardware network gateway is further configured to detect the encrypted electronic output based on an entropy of the network transmissions of the electronic device.

16. The system of claim 10 , wherein the computer hardware network gateway is further configured to store information about the artificial sensitive information in a database, and to compare information from a user with the information in the database in order to determine if the electronic device that transmitted the artificial sensitive information contains unwanted software.

17. The system of claim 10 , wherein the software agent is configured to perform the login session on a target site, and the computer hardware network gateway is configured to monitor the target site for detection of the artificial sensitive information to determine the existence of unwanted software on the electronic device.
