  • Non-signature malware detection system and method for mobile platforms
    Patent number: 8312545
    Abstract: A system and method for detecting malware on a mobile platform in a mobile network. The system and method verifies that an executable is malware-free by computing the checksum of the executable and comparing that checksum with a checksum obtained from a malware-free copy of the executable. The checksum is a sum of all 32-bit values in a code section and an import section of said executable, a byte sequence at an entry point in said executable, a size descriptor of an import table, a size descriptor of said import section, a cyclic redundancy check of said executable, or a combination thereof.
