METHOD AND SYSTEM FOR PROTECTING AGAINST UNKNOWN MALICIOUS ACTIVITIES BY DETECTING A HEAP SPRAY ATTACK ON AN ELECTRONIC DEVICE

摘要

A method and system for protecting against unknown malicious activities by detecting a heap spray attack on a electronic device are disclosed. A script is received at an electronic device from a remote device via a network and a loop operation is detected in the script that contains a write operation operable to write data to a memory of the electronic device. The amount of the data operable to be written to the memory by the write operation is determined and the data is prevented from being written to the memory if the amount of the data is greater than or equal to a threshold.

1. A method for detecting malware, comprising:
receiving data at an electronic device from a remote device via a network; detecting a loop operation in the data that contains a write operation operable to write data to a memory of the electronic device; and determining an amount of the data to be written to the memory by the write operation; and based at least on a determination that the amount of the data is greater than or equal to a threshold, identifying the write operation as potential malware and preventing the data from being written to the memory.
