Mar 26 2007 ~ "Search Engine Poisoning is a topic that we have have researched at some length. We discussed the topic briefly in an October blog post: Search Engine Typosquatting*. Our previous research focused on malicious URLs in search engine results from misspelled search terms; it was far less common to discover malicious content for legitimate search terms. In early March, a report from Sunbelt** demonstrated Microsoft Windows Live Search™ Italy returning exploit sites for extremely common search terms. Doing some additional research of our own, we performed searches for the names of financial companies, well-known banks, and lenders. The results were alarming. Many of the URLs in the search results linked to malicious sites capable of silently compromising the visitor..."

McAfee report - State of Search Engine Safety

- http://www.siteadvisor.com/studies/s...safety_may2007
June 4, 2007 ~ "...Key Findings
* Overall, 4.0% of search results link to risky Web sites, which marks an improvement from 5.0% in May 2006. Dangerous sites are found in search results of all 5 of the top US search engines (representing 93% of all search engine use).
* The improvement in search engine safety is primarily due to safer sponsored results. The percentage of risky sites dropped from 8.5% in May 2006 to 6.9% in May 2007. However, sponsored results still contain 2.4 times as many risky sites as organic results.
* AOL returns the safest results: 2.9 % of results rated red1 or yellow2 by McAfee SiteAdvisor. At 5.4%, Yahoo! returns the most results rated red or yellow.
* Google, AOL, and Ask have become safer since May 2006, with Ask exhibiting the greatest improvement. The safety of search results on Yahoo! and MSN has declined..."

Google search malware attack in progress

November 27, 2007 (Computerworld) - "A large-scale, coordinated campaign to steer users toward malware-spewing Web sites from Google search results is under way, security researchers said today. Users searching Google with any of hundreds of legitimate phrases -- from the technical "how to cisco router vpn dial in" to the heart-tugging "how to teach a dog to play fetch" -- will see links near the top of the results listings that lead directly to malicious sites hosting a mountain of malware. "This is huge," said Alex Eckelberry, Sunbelt Software's CEO. "So far we've found 27 different domains, each with up to 1,499 [malicious] pages. That's 40,000 possible pages." Those pages have had their Google ranking boosted by crooked tactics that include "comment spam" and "blog spam," where bots inundate the comment areas of sites with links or mass large numbers of them as bogus blog posts. Attackers may be using bots to plug links into any Web form that requests a URL, added Sunbelt malware researcher Adam Thomas. There's no evidence that the criminals bought Google search keywords, however, nor that they've compromised legitimate sites. Instead, they've gamed Google's ranking system and registered their own sites... One site that Thomas encountered tried to install more than 25 separate pieces of malware, including numerous Trojan horses, a spam bot, a full-blown rootkit, and a pair of password stealers. All the malicious code pitched at users is well-known to security vendors, and can only exploit PCs that aren't up-to-date on their patches... Sunbelt's company blog sports screen shots* of several Google search results lists, with malware-infecting sites identified, as well as images of the bogus codec installation dialogs and the code of one of the malicious IFRAMEs."

November 28, 2007 - "As a follow-up to our recent posts*, here’s some additional information. First, we can ring the all-clear bell. Google took action on these domains and you won’t find them anymore in Google (see Java script at URL above)... So. if you use search terms like “inurl” and “site”, you won’t see these malware pages in your results. Clever, since that’s one way for malware researchers to find stuff... And, it only cares if you’re coming from Google..."
