Abstract: An exploit detector hooks functions of a WebAssembly engine API that include functions invoked when creating a WebAssembly instance, when permissibly modifying read-write-execute (RWX) memory allocated for a WebAssembly instance, and when calling an exported WebAssembly function. Upon invocation of the hooked instance creation function(s), the detector obtains an address of RWX memory allocated for the instance, reads data stored there, and records an association between the address and the data. If the hooked function(s) for permissibly modifying RWX memory is invoked, the detector updates the data stored in the recorded association with the modified data read from the RWX memory. Based on invocation of the hooked function(s) associated with WebAssembly export function calls, the detector reads the current data in the RWX memory to be executed and compares this data to the data recorded in association with the address. If the actual and expected data differ, the detector detects a browser exploit.
