April 05, 2008 - "As we’ve seen before, this continues to be a problem on Google Groups: Fake posts pushing porn that pushes malware (fake codecs)... This really needs to get cleaned up. There’s a reason why so many of the threats that we see users getting infected with are invariably fake codec related..."

April 7, 2008 - "The infamous “Storm worm” is back and now the spam messages contain links to the domain blogspot .com - Google’s Blogger service. The spammed subjects look like “Crazy in love with you“, “I Love Being In Love With You” or “Fallen for you“. The mail body contains just simple short sentences like “I’ll never stope loving you“, “With All My Love” or “Deeply in love with you“, followed by a link to Blogger... When a curious user will follow the lure, he will be presented a Blogger web site like above. An executable file named ‘withlove.exe‘ is linked and downloaded from another fast-fluxing domain... BTW: Storm is not the first malware which invades Blogger. Last year Zlob was also present on many Blogs, waiting to show the infamous missing codec error messages. So be aware..."

16 Apr 2008 | SearchSecurity.com - "...The technique of using otherwise legitimate sites to host and deliver malware is an increasingly popular one and has continued to be effective for a number of reasons. Most importantly, users do not expect to find malware on e-commerce, news and entertainment sites that they trust and have been visiting for years. But there's also the problem of finding and removing the malicious pages. It's much easier to isolate and blackhole an entirely malicious site than it is to find and take down one infected page among thousands on a legitimate site. In his analysis of the malware utility, ISC handler Bojan Zdrnja wrote* that after infecting a new site, the program then checks with a remote server in China, possibly to confirm the new infection as part of a pay-per-infection scheme. After that operation, the tool will then connect to Google and use a specific search string to find vulnerable sites..."

4.17.2008 - "... research has uncovered a case where a museum's compromised Web server is serving malicious code based on the referrer making the request. A referrer could be, for example, a search engine such as images.google.com. As interesting as the fact that they're doing this, however, is which referrers trigger the delivery of malicious content, when others do not. In this case, the malicious content is served -only- when the referrers for the request are certain high-profile image search sites... For example, if a browser attempted to load a page with the desired image through images.google.com, malicious content was delivered. However, if a normal Google search (www .google.com) was used for the same image with the same URL, the result was the proper page, -without- the malicious redirect. So far, the list of image search sites that are used as affected referrers by the attacker are among the most high-profile image searches on the web:
* images.google.com
* images.search.yahoo.com
* www .altavista.com/image/default
* search.live.com/images/
... another screenshot of the same page, but with referrer data disabled. This page contains the normal page content, not the malicious code. The decision on what content to send is made on the server, so this attack is browser-independent. Regardless of which browser is used, if the referrer information on the request is one of the affected image search engines, the malicious content is delivered... it seems as though the museum's page has also been compromised with a search engine poisoning attack. Beyond the normal reasons for such a compromise, we can theorize that this may have been done to increase the site's search ranking, making it more likely for its images to come up in a search. As a result, more systems are likely to be infected by the malicious content."

Google Pages Porn Malware Invasion Continues Unabated
- http://sunbeltblog.blogspot.com/2008...-invasion.html
April 17, 2008 - "... Hundreds of thousands of pages, if not over a million. Examples (warning: graphic language)... And there’s also splogs pushing malware, not as porn, but just off of keywords. Here’s a search for “Symantec Download”... file being pushed, setup.exe, is a trojan. Or, let's use the search term “McAfee download”... (I’m not picking on these AV companies, if you do similar searches for Sunbelt products, you’ll hit these types of things as well.) These slimeballs are using all kinds of keywords. Here’s some more, like Blackberry Ringtones and Free Messenger Download, returning spam links... Or how about keeping it simple, and just saying “free download”? Malware!... A large part of this is most certainly caused by bots uploading stuff, breaking the CAPTCHA. They may not break it all the time, but they do break it probably 10% of the time. That’s enough to upload a ton of garbage..."

05/02/2008 - "Google adwords account holders are being targeted by criminals out to trick them into handing over credit card information using a clever URL spoof that has gained popularity in recent weeks. On the face of it, the scam follows a traditional attack route involving the sending of spam emails to random Internet addresses in the hope of finding users who have purchased adwords. The email claims that the user's account payment has failed and asks them to "update payment information", again a transparent ploy by today's standards... As obvious as this might sound, the unwary might easily be tricked by the convincing http ://adwords .google .com/select/login link embedded in the email, a perfect copy of the correct Google login address. This one, however, actually leads to hxxp ://www .adwords .google .com.XXXX.cn/select/Login [address altered], an obfuscated address that directs to a site associated with IPs in Germany, Romania, and the Czech Republic. The site is a good copy of the real Google adword site, and appears to let users login using their real account details - any account details will work in fact. Entering payment details results in that information being posted using an SSL link to a remote server after which the account will ripped off. The attack has been publicized by security software company Trend Micro*, but the disarmingly simple scam is widespread enough to have been received by ordinary users in recent days..."

June 24, 2008 (Infoworld) - "...Stopbadware.org released data on "badware" Web sites on Tuesday, saying that Google was one of the top five networks responsible for hosting these dangerous Web sites.
The numbers show that China is now a top source of malicious Web sites -- China-based networks hosted more than half of the malicious Web sites tracked by the group -- but Google's appearance on the list is perhaps more remarkable...
A year ago, Google did not appear on Stopbadware.org's list of the top 10 sources of badware, but recently scammers and online criminals have turned to Google's Blogger service to host malicious or spyware-related Web pages... In March, Google was the top badware network tracked by Stopbadware*..."

A Million Search Strings to Get Infected
- http://blog.trendmicro.com/a-million...-get-infected/
August 15, 2008 - "...We received several reports from the North American region earlier today about users being victimized by a rogue antispyware, which these users have downloaded after they have somehow been convinced to click on malicious links. These links point to malware that caused overt signs (such as popup balloons and modified wallpapers) to appear in the PC suggesting that the system has indeed been infected. This is not goodwill, though — because downloading the ‘trial version’ only scans the system. To remove the infection the user will have to purchase the entire antispyware for real money. Users may be infected via spammed email messages, spammed instant messages, or even via ads served in social networking sites. Soon enough, we’ve discovered not one but two fake antivirus software. This time the attack is made possible through a mass SEO poisoning involving several compromised Web sites. This development has certainly upped the chances of the rogue antispyware gaining mileage. How does this work? A simple Google/Yahoo! search can lead you to malware-serving site. Search strings such as “changes on the river amazon” or “changes made for mount Pinatubo” will lead you to a malicious Web site. Users who happen to use these strings will find themselves going down the long road of nasty redirections... After all the fake notifications, the user will be asked to download AV2009Install_880488.exe. The other fake antivirus will lead users to hxxp ://scan. free-antispyware-scanner. com ... This will ask the user to download setup_100722_3.exe instead of AV2009Install_880488.exe. (Note that the final agenda for both and most rogue antispyware scams is extortion. Users who fall for this scam pay a certain amount of money to the malware writers to purchase the full version of the fake antispyware.)
According to our investigation, there are about several dozen domains involved that are currently compromised. The hackers were able to upload PHP scripts that contain various text strings designed for SEO poisoning (SEO poisoning is manipulating or influencing the natural page rankings of search results in order to get more hits than a page really deserves). This is not the first time Trend Micro has seen this incident, a previous SEO poisoning of this scale was also discovered December 2007, with SEO poisoning pages hosted on Blogspot. This time around, compromised web sites were used instead. Digging a little bit deeper, we’ve also found out that the hackers have almost 1 million search phrases at their disposal for SEO poisoning. These search phrases covers the range from free downloads, lyrics, travel, politics and anything in between. Malicious sites have “CLICK HERE! ALL INFORMATION!” and “CLICK HERE! WANT TO KNOW MORE ABOUT” as their page titles, so it will be best to avoid clicking through Google/Yahoo! results that have those aforementioned site titles."

Continuing problem - malware advertised in Google Adwords
- http://sunbeltblog.blogspot.com/2008...are-being.html
August 23, 2008 - "Google continues to have a problem with malware being advertised in Google Adwords, in this case, for the trojan Antivirus XP 2008... An exacerbating part of the problem, of course, is that Google Adwords are massively syndicated to other sites, including heavy-hitters like CNET, all of whom may unknowingly push malware through these ads. A lot of people can get affected by this type of problem."
