Detecting and removing injected elements from content interfaces
Systems and methods are disclosed for detecting and removing injected elements from content interfaces. In one implementation, a processing device receives a content interface from a content provider, processes the content interface to identify elements of the interface that may not have been received from the content provider, compares the content interface with corresponding reference interfaces to identify elements of the content interface that are not present in the reference interfaces, processes the identified elements to determine how the identified elements affect a rendering of the content interface on the device, and modifies a rendering of the content interface on the device based on the manner in which the identified elements affect the rendering of the content interface on the device.
1. A method comprising:
receiving a webpage associated with a content provider, wherein the webpage comprises a plurality of content elements;
comparing, by a processing device, the webpage loaded by the device with one or more reference webpages originating from the content provider to detect a first malware element of the plurality of content elements of the webpage loaded by the device that is not present in the one or more reference webpages, wherein the first malware element is loaded after expiration of a time interval subsequent to a loading of one or more other content elements of the webpage; and
modifying a first parameter of code associated with the first malware element to interrupt a display of the first malware element via the webpage on the device, wherein at least a portion of the code associated with the first malware element is maintained.
2. The method of claim 1 , further comprising identifying the first malware element is capable of being injected by a third-party service into the webpage.
3. The method of claim 1 , further comprising identifying the first malware element was previously injected into another webpage by a third-party service.
4. The method of claim 1 , further comprising identifying the first malware element is capable of being injected by a third-party service and not present in the one or more corresponding reference interfaces.
5. The method of claim 4 , further comprising comparing a first attribute of the first malware element with one or more attributes of one or more elements from the one or more reference webpages, wherein the first attribute comprises at least one of: a position of the first malware element, a size of the first malware element, or a shape of the first malware element.
6. The method of claim 1 , further comprising identifying the first malware element comprises one or more source domains that are not included in a set of valid source domains.
7. The method of claim 1 , further comprising determining the first malware element overlays one or more content elements of the webpage.
8. The method of claim 1 , further comprising identifying a removal of one or more content elements of the webpage.
9. The method of claim 1 , further comprising identifying a removal of one or more content elements of the webpage after expiration of a time interval.
10. The method of claim 1 , wherein the first parameter comprises one or more coordinates pertaining to an orientation of the first malware element.
11. The method of claim 1 , further comprising removing one or more parameters of the first malware element.
12. The method of claim 1 , further comprising replacing a content element of the webpage with a substitute content element.
13. The method of claim 1 , further comprising generating a content element that encapsulates the first malware element.
14. The method of claim 13 , wherein the content element comprises an invisibility attribute.
15. The method of claim 1 , further comprising determining the first malware element is listening for one or more inputs to be provided in relation to the webpage.
16. The method of claim 15 , further comprising modifying the webpage to process an input prior to processing of the input by the first malware element.
17. A system comprising:
a memory; and
a processing device, coupled to the memory, to:
receive a webpage associated with a content provider, wherein the webpage comprises a plurality of elements;
compare the webpage loaded by the device with one or more corresponding reference webpages originating from the content provider to detect a first malware element of the plurality of elements of the webpage loaded by the device that is not present in the one or more corresponding reference webpages, wherein an element of the plurality of elements is removed after expiration of a time interval; and
modify a first parameter of code associated with the first malware element to interrupt a display of the first malware element via the webpage on the device, wherein at least a portion of the code associated with the first malware element is maintained.
18. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processing device, cause the processing device to:
receive a webpage associated with a content provider, wherein the webpage comprises a plurality of elements;
compare the webpage loaded by the device with one or more corresponding reference webpages originating from the content provider to detect a first malware element of the plurality of elements of the webpage loaded by the device that is not present in the one or more corresponding reference webpages, wherein an element of the plurality of elements is removed after expiration of a time interval; and
modify a first parameter of code associated with the first malware element to interrupt a display of the first malware element via the webpage on the device, wherein at least a portion of the code associated with the first malware element is maintained.
