Google bots subversion

There is a lot of truth in saying that every tool can be used by good and by evil. There is no point in blocking the tools themselves as the attacker will turn to new tools and subvert the very familiar tools in unexpected ways. Now Google crawler bots were turned into such a weapon to execute SQL injection attacks against websites chosen by attackers.

Instead, think that this is a prime case of a familiar tool that comes back to your website regularly subverted into doing something evil. You did not expect that to happen and you cannot just block the Google from your website. This is a perfect example of a security attack where your application security is the only way to stop the attacker.

The application must be written in such a way that it does not matter whether it is protected by a firewall – you will not always be able to block the attacks with the firewall. The application must also be written so that it withstands an unanticipated attack, something that you were not able to predict in advance would happen. The application must be prepared to ward off things that are not there yet at the time of writing. Secure design and coding cannot be replaced with firewalls and add-on filtering.

Only such securely designed and implemented applications withstand unexpected attacks.
