Systems and methods for javascript based application cybersecurity

A non-transitory computer readable medium containing instructions that when executed by at least one processor cause the at least one processor to perform cybersecurity operations comprising:

• detecting at least one JavaScript enabled application, wherein the JavaScript enabled application is configured to exhibit native functionality and to generate a plurality of execution contexts following receipt of an original input code;
• injecting a JavaScript cybersecurity agent within the at least one detected Javascript enabled application, wherein the injected JavaScript cybersecurity agent is configured for execution prior to execution of the original input code by the JavaScript enabled application;
• and
• patching exposed application programming interfaces using the injected JavaScript cybersecurity agent, wherein the patching is configured to cause patched application programming interfaces to exhibit non-native functionality different from the native functionality, and wherein the non-native functionality differs for different execution contexts of the JavaScript enabled application in order to thwart exploitations.

A method for performing cybersecurity operations, the method comprising:

• detecting at least one JavaScript enabled application, wherein the JavaScript enabled application has a plurality of execution contexts and is configured to exhibit native functionality;
• injecting a JavaScript cybersecurity agent within the at least one detected Javascript enabled application, wherein the injected JavaScript cybersecurity agent is configured for execution prior to code associated with the JavaScript enabled application;
• and
• patching exposed application programming interfaces using the injected JavaScript cybersecurity agent, wherein the patching is configured to cause the patched application programming interfaces to exhibit non-native functionality different from the native functionality, and wherein the non-native functionality differs for differing execution contexts of the JavaScript enabled application in order to circumvent exploitations.
