Using Wget to surf SEO attacked websites link

There have couple of ways used to detect malicious redirects to malicious sites. For me, the safety way is used wget command-line tools. This tools works at Linux, Mac and Windows as well. You can simulate the traffic like normal browsers do by configuring such as referer, agent-string, and etc.

Example,
# wget --referer=http://www.google.com "http://www.malicioussite.com/"

# wget --referer=http://www.yahoo.com "http://www.malicioussite.com/"

Faking user-agent with Wget
wget --refer=http://www.google.com --user-agent="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1)" "http://www.malicioussite.com/"

It is important to include user agent string because more and more sites excluding browsing by "unapproved" browsers.

Example:

wget -k -m --referer=http://www.google.com --user-agent="Mozilla/5.0 (Windows; U; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)" "http://visualflowdesigns.com/ecuuz.php?t=polish+president+killed"
