Warning on search engine safety
Some net searches are leading users to websites that
expose them to spam, spyware and other dangerous downloads, reveals a
According to the research the most dangerous words to search for are “free screensavers”.
The report found that 64% of the sites found using this phrase were flagged as causing problems for users.
The authors urged search sites to tighten up rules to ensure users are not inadvertently exposed to harm.
It is well known that visiting sites offering porn,
gambling and free MP3s leaves users at serious risk of falling victim
to spyware and adware. However, the research by Ben Edelman and Hannah
Rosenbaum reveals that those carrying out searches for innocuous
subjects are at risk too.
The report looked at the websites returned for 1,394 popular keywords searches found via Google, Yahoo, MSN, AOL and Ask.
The results returned for each search term were then
analysed using the Site Advisor security tool. Once installed this
piece of software warns users when they browse websites known to be
The most benign of the pages that Site Advisor flags up

In one case signing up with one site led to a test e-mail address getting more than 300 spam messages per week.
Some of these risky sites use security flaws and loopholes in browsers
to install software without users’ knowledge and can lead to that
machine being hijacked or to a user losing personal data.
The riskiest search terms were associated with downloads
(such as “screensavers” and “free ringtones”) and file-sharing (such as
“Bearshare” and “limewire”). Searching under these categories returned
a substantial proportion of dangerous sites.
The authors speculate that spammers and scammers are
turning to websites to try to snare victims as efforts are made to stop
spam before it reaches e-mail inboxes.
“Where internet users go, attackers follow,” wrote the authors.
Across all searches approximately 4-6% of sites returned
were flagged as dangerous. The authors noted that this was more
“alarming” than it first appeared because American net users carry out
almost 6 billion searches per month. This translates to 285 million
clicks on these potentially dangerous sites every month.
“Even a single visit to a dangerous site can have
serious and lasting implications for the average internet user,” wrote
The number of risky sites increases when users click on
sponsored results – the adverts generated to accompany particular
search terms. Dangerous sites are two to four times as common in
sponsored results found the research.
“We are troubled by the untrustworthiness of search engines’ ads,” said the authors.
The authors urged the search engines to get much tougher
on those who buy adverts to accompany searches and expose those that
“We’re alarmed by the scope of these problems – by the
many ways search engines lead users to sites that turn out to be
untrustworthy or worse,” concluded the report.
