Infected google.com, yahoo.com and blogspot.com

["MustLive" <mustlive () websecurity com ua>]

Hello participants of Full-Disclosure.

Let's talk about infected sites of Google and Yahoo.

As I wrote yesterday in my post Infected google.com, yahoo.com and
blogspot.com (http://websecurity.com.ua/3786/), web sites of Google and
Yahoo were infected over the last 90 days. All mentioned quotes (from
Google's site) are at state of yesterday (19.12.2009) and you can see
current state of these sites by provided links. Google updates their data
regularly.

When I found possibility to use Safe Browsing from Google
(http://websecurity.com.ua/3785/) for checking of the sites for
infectiousness, at first I made diagnostic of few popular web sites. And
I've got very interesting results ;-).

Among the first sites checked by me were google.com, yahoo.com and
blogspot.com, which were found infected over the last 90 days. That
blogspot.com (it's one of domains of Google's service Blogger) was found
infected didn't surprise me, because last year I wrote about that this site
of Google was using for malware spreading (http://websecurity.com.ua/2310/)
(according to data of Sophos), but that google.com itself was infected and
also yahoo.com, it's already a news.

Google Safe Browsing diagnostic page for google.com
(http://google.com/safebrowsing/diagnostic?site=google.com) is informing
about (quote):

    This site is not currently listed as suspicious.

    Part of this site was listed for suspicious activity 1 time(s) over the
past 90 days.

And also (quote):

    Of the 70146 pages we tested on the site over the past 90 days, 4
page(s) resulted in malicious software being downloaded and installed
without user consent. The last time Google visited this site was on
2009-12-19, and the last time suspicious content was found on this site was
on 2009-12-16.

    Malicious software includes 7 scripting exploit(s), 1 trojan(s).
Successful infection resulted in an average of 1 new process(es) on the
target machine.

Also information about that malicious software is hosted on 14 domains, that
7 domains appear to be functioning as intermediaries for distributing
malware to visitors of this site, and also (quote):

    Over the past 90 days, google.com appeared to function as an
intermediary for the infection of 10 site(s)

So Google's site was infected recently (16.12.2009). After that it was
cleared from infection, but the fact remains.

Thus Information Leakage at this service of Google leaded to leakage of
information about infectiousness of own site. This is such humor of Google -
to disclose information about infectiousness of own sites :-). From other
side - it's good that Google honestly admit it.
