Damage examples

Attacks to embedded software

The more equipments increase, such as connected vehicles and smart consumer electronics that are always-on connection with the internet, the higher the rate of cracking on embedded software increases. There are many cases where equipments are automatically connected to the external network.
The shift to high functionality has been realized in favor of the internet connection on the one hand, an attack from the outside has become easier on the other hand, and the security hole has been spreading.
It can be easily imagined that an individual cracking method could be disclosed through the Internet as a general cracking tool, and the damage might spread explosively. Under such circumstances, perfect measures against cracking on embedded equipments are demanded from now.

Example: Attacks to in-vehicle systems

  • Interception of in-vehicle LAN communications
  • Invasion to in-vehicle LAN from the wide area network
  • Disclosure of the immobilizer certification key and theft of a vehicle
  • Leaks of vehicle inherent information such as vehicle ID
  • Unauthorized control of the brake or the wiper from outside while a vehicle is driving
  • Illegal unlocking of the door from a remote place

Outline of the Product

This is an anti-tampering*1 security software preventing Linux applications including .SO file from cracking damages, such as analysis and tampering by reverse engineering and the outflow of the intellectual property. This software has been developed to protect Linux applications from cracking*2, based on our anti-tampering technologies developed for CrackProof™ Windows version .
Since the anti-tampering processing is completed simply by a drag-and-drop of the target app for security processing, it is possible to introduce security measures without putting extra burden on the application developer.

* 1: Resistance to analysis and tampering * 2: Illegal analysis of programs and tampering

Security Functions

Function types functions Explanation
Static Analysis
Prevention Functions
AES Encryption Encrypts codes by AES to prevent disassembling.
Tampering Check Prevents tampering with files.
Symbol Deletion Deletes symbol information to make it more difficult to analyze by disassembling.
Dynamic Analysis
Prevention Functions
Debugger Prevention Prevents analysis by debuggers.
Memory Snapping Prevention Prevents memory snapping shot such as core dumping.
SO Injection*3 Prevention Prevents injection of malicious SO.

*3 To read the SO, that the developer does not intend, in the memory and let it execute aiming to make an analysis or else.
