Massive SQL Injections Through Search Engine's Reconnaissance


From the lone Chinese SQL injectors empowered with point'n'click tools for massive SQL injection attacks, to the much more efficient and automated botnet approach courtesy of the, for instance, ASProx botnet the process of automatically fetching URLs from public search engines in order to build hit lists for verifying against remote file inclusion attacks and potential SQL injections, remains a commodity feature in a great number of newly released malware bots.

In 2004, the Santy worm advertised the feature to the not so efficiently centered hordes of script kiddies back then. Due to its simplicity, but huge potential for abuse, the concept of SQL injections through search engines reconnaissance has not only reached a real-time syndication with the latest remotely exploitable web application vulnerabilities, but has also converged with remote file inclusion checks, local file inclusion checks, and ip2geolocation to unethically pen-test a particular country going beyond its designated domain extension.

A recently released malware bot is once again empowering the average script kiddie with the possibility to take advantage of the window of opportunity for each and every remotely exploitable web application flaw featured at Milworm, based on its real-time syndication of the exploits. Moreover, the IRC based bot is also featuring a console which allows manual exploitation or intelligence gathering for a particular site.

Some of the features include:
- Remote file inclusion
- Local file inclusion checks ()
- MySQL database details
- Extract all database names
- Data dumping from column and table
- Notification issued when Google bans the infected host for automatically using it


The commoditization of these features results in a situation where the window of opportunity for abusing a partcular web application flaw is abused much more efficiently due to the fact that reconnaissance data about its potential exploitability is already crawled by a public search engine - often in real time.

The concept, as well as the features within the bot are not rocket science - that's what makes it so easy to use.
