Abstract: Provided are a computer program product, system, and method for injecting trap code in an execution path of a process executing a program to generate a trap address range to detect potential malicious code. A specified type of command is processed in application code and, in response, trap code is executed to allocate a trap address range. The specified type of command is executed in the application code. A determination is made as to whether an accessing application accesses the trap address range. At least one of transmitting a notification that the accessing application comprises potentially malicious code, monitoring the execution of the accessing application, and restricting execution of the accessing application is performed in response to determining that the accessing application accessed the trap address range.
