Virus Trackers Find Malware With Google

Casper the Angry Ghost writes "Malware hunters have figured out a way to use the freely available Google SOAP Search API, as well as WDSL, to find dangerous .exe files sitting on thousands of Web servers around the world. Queries can be written to examine the internals of web-accessible binaries, thus allowing the hunters to identify malicious code from across the internet." From the article: "We're finding literally thousands of sites with malicious code executables. From hacker forums, newsgroups to mailing list archives, they're all full of executables that Google is indexing. About 15 percent of the results came back from legitimate Web sites hijacked by malicious hackers and seeded with executables."

do no evil, rat out evil

[yagu]

This raises Google's "no evil" equity significantly. Any mechanism to sniff out, identify, and hopefully proactively take measure to protect against the evil that is the web and its sinister demographic is a good thing.

So, Google takes the "do no evil" a step further and calls evil out.

There is a quote from the article I don't quite understand,

"While we do not believe that the fact that Google is indexing binary file contents is a large threat, this is further evidence of a rise in Web sites being used as an method of storing and distributing malicious code," Websense said in a research note announcing the experiment.

Is there some potential badness that Google is indexing binary file content? What might that be?

It's not really Google that's doing it, it's Websense using a Google tool.

In any case, the only thing I can figure about the quote is that Google indexing these sites helps to spread the malware around. Somebody could type in "l337 hax0rs hax" and end up at a malware site.

SOAP?

[breckinshire]

Google SOAP Search API

Is there anything that the Snakes on a Plane Search API can't do?

Securing the Search Engine?

[Alamoth]

It seems to me that the possibilities for uses of this application of SOAP would be highly beneficial. My initial thought would be the ability to filter your Google searches so that websites that are potentially carrying MalWare are either flagged or not shown at all.

The 15% of sites that are reputable sites being attacked are the biggest threat. These are probably websites people visit often, and people should be warned. Perhaps even web browsers such as firefox and i.e. could incorporate the API into a toolbar and warn users before a dangerous site loads.

My only question is how long does it take for the API to verify the potential threat of a webserver? Is it fast enough for these applications to be feasible? No one wants to wait for their websites to load.

How to

[mailspam]

Search on google for something like signature:00004550 inurl:exe
Then, click View HTML

Re:Little did you know

Actually, the real reason it was ineffective was because they put the executables in an article link.

Indexing these MAY be exploitable

[ratboy666]

The idea is to code the exploit in such a way that Google extracts the exploit itself as the content description in the index. This probably gives 200 bytes or so for the entire exploit (maybe more, I don't have time to try this stunt right now).

The idea is to put up useful content into the web site, along with the exploit. Google will index, and when the target searches google, the code will be injected into the search results.

Of course, this needs hacking; both trying to figure out what google will allow in the content section, and to find a browser exploit that can be exploited.

Just sayin...

Your point of trust (as the target) is your browser. Which means ONLY open source browsers should be used. Those, at least, are controllable as to the exposure and behaviour when being delivered content.
