Anonymizing Attacks With Google [via]

This is a repost cause the article rocks:

Google can be utilized to hack into websites – actively exploiting them not information gathering by the use of “Google Hacking”, although that is how most of the sites vulnerable to RFI attacks are found.

By placing a URL on any web page, Google will find it, visit it and then index it. With this mechanism, it is possible to anonymize attacks on third party web sites through Google by the use of its crawler.

A malicious web page is constructed by an attacker, containing a URL built like so:
1. Third party site URI to attack.
2. File inclusion exploit.
3. Second URI containing a malicious PHP shell.

Example URL:

Google will harvest this URL, visit the site using its crawler and index it. Meaning accessing the target site with the URL it was provided and exploiting it unwittingly for whoever planted it. It’s a feature, not a bug.

This is currently exploited in the wild. For example, try searching Google for:

And note, as an example:
Which is no longer vulnerable. The %20 seems out of place, but this is how it is shown in the search.

Why use a botnet when one can abuse the Google crawler, which is allowed on most web sites?


  •  This attack was verified on Google, but there is no reason why it should not work with other search engines, web crawlers and web spiders.
  • File inclusions seem to tie in well with this attack anonymizer, but there is no reason why others attack types can’t be used in a similar fashion.
  • The feature might also be used to anonymize communication, as a covert channel.
