    Malicious Code: Attackers Exploiting News of Benazir Bhutto Assassination
    - http://www.websense.com/securitylabs...hp?AlertID=834
    December 27, 2007 - "Websense Security Labs has discovered malicious Web sites attempting to capitalize on the breaking news of the assassination of Benazir Bhutto. These sites attempt to infect users seeking more information about the event. This activity is similar to past news events, where attackers used malicious sites containing information about the event to infect visitors. In this case, the first infected site found by Websense Security Labs was the second result in a Google search using a generic and simple keyword. Therefore, the site likely to receive large amounts of traffic. Clicking on the link in the search results did not trigger a warning from Google that the site may be malicious..."

When users search for “Superbowl,” Google search results turn up the following (links to malware)... what’s interesting in this case is that the malicious URLs are once again found in the servers of the Czech hosting provider believed to be hacked.

    Search Engine Spam increasing
    - http://www.messagelabs.com/intelligence.aspx
    MessageLabs Intelligence (PDF report): January 2008 - "...much of this type of spam in recent weeks has also revealed a significant hike in the proportion of spam abusing search engine redirects. Typically Google and Yahoo search engines have been used in these spams. Search engine spam accounts for 17% of spam in January and has been in circulation for only a few weeks. Search engine spam is a technique that allows the spammer to include a link constructed from a search engine query in an email message. When followed, the link will resolve in the spammer’s forged web site. This means that the spammers can send messages without directly mentioning the spam website, which makes it difficult for traditional anti-spam products to detect the malicious link. While they may recognize known spam sites, they cannot reasonably block links to legitimate search engine sites. eBay recently instituted some changes to circumvent this type of attack method... the link in the email passes some special parameters to the Google search engine, using the inURL: keyword (which focuses the search only on the domain listed), and the BtnI= keyword (typically used by the “I’m feeling Lucky” button on Google)..."

    Exclamation Google blog used to spread malware

    FYI...

    - http://www.networkworld.com/news/200...ogle-blog.html
    01/31/08 - "A Google-hosted blog is running phony security content that's linked to malware, as well as using Google's automated notification service to try to entice subscribers to click on an infected link, says one security expert. To trick readers looking for information related to legitimate security products, the blog - which has been spotted working under the name "Brittany" - has copied content related to security vendors Symantec, Trend Micro and Aladdin Knowledge Systems, says Ofer Elzam, director of product management in Aladdin's eSafe division... Google states in its usage policy that "Google does not monitor the contents of Blogger.com and Blogspot.com, and takes no responsibility for such content. Instead, Google merely provides access to such content as a service to you"..."

    Question

    FYI...

    All Your iFrame Are Point to Us (from the Google Anti-Malware Team)
    - http://googleonlinesecurity.blogspot...int-to-us.html
    February 11, 2008 - "...In the past few months, more than 1% of all search results contained at least one result that we believe to point to malicious content and the trend seems to be increasing... Some malware distribution sites had as many as 21,000 regular web sites pointing to them. We also found that the majority of malware was hosted on web servers located in China. Interestingly, Chinese malware distribution sites are mostly pointed to by Chinese web servers. We hope that an analysis such as this will help us to better understand the malware problem in the future and allow us to protect users all over the Internet from malicious web sites as best as we can. One thing is clear - we have a lot of work ahead of us."

    "On March 4, 2008 reports of an IFRAME attack coming from ZDNet Asia began to surface. Attackers appear to have abused the ZDNet search engine's cache by exploiting a script injection issue which is then being cached in Google. Clicking the affected link in Google will cause the browser to be redirected to a malicious site which attempts to install a rogue ActiveX control. On March 6, 2008 the research that discovered the initial attack published an update stating that a number of CNET sites including TV.com, News.com and MySimon.com are also affected by a similar issue.

    Exclamation Google Ads abused to serve Spam and Malware

    FYI...

    Google Ads abused to serve Spam and Malware
    - http://preview.tinyurl.com/2opnkh
    March 17, 2008 (McAfee Avert Labs) - "Early this year we observed spammers using Google page ads in HTML-formatted emails to redirect users who click the spammed URL to the spammers’ sites... At first we thought Google page ads were being used to conceal the actual URL and subvert traditional anti-spam detection techniques. However, it seems one can change the linked URL to point to any site of your choice–as no validation appears to be done on Google’s end. One can even point the Google page ad to executable files (malware authors have started doing this), and the link will redirect and download the malware just fine. It’s kind of ironic given than Google is very strict about the kind of file attachments one can upload/download via their Gmail service... Google must be aware of this redirect abuse, and it’s hard to understand why they don’t prevent these -redirects- working for known bad file types or for spam and malware sites."

    Exclamation Massive IFRAME SEO Poisoning Attack Continuing...

    Massive IFRAME SEO Poisoning Attack Continuing...

    - http://ddanchev.blogspot.com/2008/03...ng-attack.html
    March 28, 2008 - "Last week's massive IFRAME injection attack is slowly turning into a what looks like a large scale web application vulnerabilities audit of high profile sites. Following the timely news coverage, Symantec's rating for the attack as medium risk, StopBadware commenting on XP Antivirus 2008, and US-CERT issuing a warning about the incident, after another week of monitoring the campaign and the type of latest malware and sites targeted, the campaign is still up and running, poisoning what looks like over a million search queries with loadable IFRAMES, whose loading state entirely relies on the site's web application security practices - or the lack of. What has changed since the last time? The number and importance of the sites has increased, Google is to what looks like filtering the search results despite that the malicious parties may have successfully injected the IFRAMEs already, thus trying to undermine the campaign, new malware and fake codecs are introduced under new domain names, and a couple of newly introduced domains within the IFRAMES themselves... The main IPs within the IFRAMES acting as redirection points to the newly introduced rogue software and malware, remain the same, and are still active. The very latest high profile sites successfully injected with IFRAMES forwarding to the rogue security software and Zlob malware variants: USAToday.com, ABCNews.com, News.com, Target.com, Packard Bell.com, Walmart.com, Rediff.com, MiamiHerald.com, Bloomingdales.com, PatentStorm.us, WebShots.com, Sears.com, Forbes.com, Ugo.com, Bartleby.com, Linkedwords.com, Circuitcity.com, Allwords.com, Blogdigger.com, Epinions.com, Buyersindex.com, Jcpenney.com, Nakido.com, Uvm.edu, hobbes.nmsu.edu, jurist.law.pitt.edu, boisestate.edu... For the time being, Google is actively filtering the results, in fact removing the cached pages on number of domains when I last checked, the practice makes it both difficult to assess how many and which sites are actually affected, and of course, undermining the SEO poisoning, as without it the input validation and injecting the IFRAMEs would have never been able to attract traffic at the first place. The attack is now continuing, starting two weeks ago, the main IPs behind the IFRAMES are still active, new pieces of malware and rogue software is introduced hosting for which is still courtesy of the RBN, and we're definitely going to see many other sites with high page ranks targeted by a single massive SEO poisoning in a combination with IFRAME injections. Which site is next? Let's hope not yours..."

    2008-03-28 - "...Danchev... published a blog about another batch of servers getting injected with malicious code and we have confirmed the attack here at Symantec. If you're an IT administrator, you will want to temporarily add them to the list of IPs to filter (block):
    * 72.232.39.252
    * 195.225.178.21
    * 89.149.243.201
    * 89.149.220.85
    In the past we've seen many low-profile sites being targeted with the IFRAME attack, but this time the list of hacked sites include many high-profile sites as well..."

    31 March 2008 - "...ScanSafe found the amount of time a website hosting malicious code remains live increased during the second half of 2007. Malware on infected sites remained live for an average of 29 days in 2H07, up 62 per cent from the first half of the year. Forms of malware undetected by scanner packages have an even a longer shelf life once they compromise a site, persisting an average of 61 days in the second half of 2007."

    31 Mar 2008 - "A malware attack targeting search engine results is continuing to haunt several high-profile sites. The attack uses the common cross-site scripting practice of embedding pages with small IFrame tags which redirect the user to a malicious page on a third-party site... The hackers have compromised search result pages, using search engine optimisation techniques to hijack search results and send users to sites which host malicious downloads. Among the sites said to be compromised are major news outlets ABC, USAToday and Forbes, and retailers Wal-Mart, Target and Sears...
