Methods, systems, and media for detecting alteration of a web page

1. A method for detecting alteration of a web page, comprising:

requesting, using a hardware processor of a user device, a web page;

receiving, using the hardware processor of the user device, the web page;

analyzing, using the hardware processor of the user device, the web page;

generating, using the hardware processor of the user device, a forensic footprint associated with the web page based on the analyzing;

requesting a reference footprint using an identifier corresponding to the web page from a server;

receiving the reference footprint from the server;

determining, using the hardware processor of the user device, whether the forensic footprint matches the reference footprint associated with the web page; and

in response to determining that the forensic footprint does not match the reference footprint, blocking, using the hardware processor of the user device, at least a portion of the web page from being presented.

2. The method of claim 1 , wherein the forensic footprint comprises at least one of a size of the web page, a number of scripted files included in the web page, a number of user input fields included in the web page, a number of selectable icons included in the web page, a number of images included in the web page, and information indicating content of the web page.

3. The method of claim 1 , wherein the reference footprint is generated prior to the receiving.

4. The method of claim 1 , further comprising at least one of redirecting a browser to another web page and presenting a notification to a user.

5. The method of claim 1 , further comprising, in response to determining that the forensic footprint matches the reference footprint, iteratively performing the analyzing, the generating, and the determining after a predetermined amount of time.

6. A system for detecting alteration of a web page,

comprising:

a hardware processor of a user device configured to:

request a web page;

receive the web page;

analyze the web page;

generate a forensic footprint associated with the web page based on the analyzing;

request a reference footprint using an identifier corresponding to the web page from a server;

receive the reference footprint from the server;

determine whether the forensic footprint matches reference footprint associated with the web page; and

in response to determining that the forensic footprint does not match the reference footprint, blocking at least a portion of the web page from being presented.

7. The system of claim 6 , wherein the forensic footprint comprises at least one of a size of the web page, a number of scripted files included in the web page, a number of user input fields included in the web page, a number of selectable icons included in the web page, a number of images included in the web page, and information indicating content of the web page.

8. The system of claim 6 , wherein the reference footprint is generated prior to the receiving.

9. The system of claim 6 , wherein the hardware processor is further configured to perform at least one of redirecting a browser to another web page and presenting a notification to a user.

10. The system of claim 6 , wherein the hardware processor is further configured to, in response to determining that the forensic footprint matches the reference footprint, iteratively perform the analyzing, the generating, and the determining after a predetermined amount of time.

11. A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor of a user device, cause the processor to perform a method for detecting alteration of a web page, the method comprising:

requesting a web page;

receiving, at the user device, the web page;

analyzing a web page;

generating a forensic footprint associated with the web page based on the analyzing;

requesting a reference footprint using an identifier corresponding to the web page from a server;

receiving the reference footprint from the server;

determining at the user device whether the forensic footprint matches reference footprint associated with the web page; and

in response to determining at the user device that the forensic footprint does not match the reference footprint, blocking at least a portion of the web page from being presented.

12. The non-transitory computer-readable medium of claim 11 , wherein the forensic footprint comprises at least one of a size of the web page, a number of scripted files included in the web page, a number of user input fields included in the web page, a number of selectable icons included in the web page, a number of images included in the web page, and information indicating content of the web page.

13. The non-transitory computer-readable medium of claim 11 , wherein the reference footprint is generated prior to the receiving.

14. The non-transitory computer-readable medium of claim 11 , further comprising at least one of redirecting a browser to another web page and presenting a notification to a user.

15. The non-transitory computer-readable medium of claim 11 , the method further comprising, in response to determining that the forensic footprint matches the reference footprint, iteratively performing the analyzing, the generating, and the determining after a predetermined amount of time.
