Abstract
Methods and devices for tracking data flows in a computing device include monitoring memory in a hardware component of the computing device to identify a read operation that reads information from a tainted memory address, using heuristics to identify a first, second, and third number of operations performed after the identified read operation, marking memory addresses of write operations performed after first number of operations and before the second number of operations as tainted, and marking memory addresses of write operations performed after the third number of operations and before the second number of operations as untainted.
