More in-depth analysis of email scam links

In my last post  http://security5magics.blogspot.com/2015/12/an-obvious-e-mail-scam-lets-see-where.html I ran through a quick analysis of a very prominent e-mail scam used today. The scam uses a link which has a PHP file holding a piece of java script at the end. The java script is a redirect to another site, usually a fake pharmacy site. I felt showing a quick decoding of what the java script does, the following code is very similar to the code from my first post, but is from a different spam e-mail I received today, which leads to a different site. Check it out. script type="text/javascript" function suddenlye() { suddenlya = 5; suddenlyb = [124, 110, 115, 105, 116, 124, 51, 121, 116, 117, 51, 113, 116, 104, 102, 121, 110, 116, 115, 51, 109, 119, 106, 107, 66, 44, 109, 121, 121, 117, 63, 52, 52, 120, 114, 102, 119, 121, 117, 110, 113, 113, 120, 123, 102, 113, 122, 106, 51, 119, 122, 44, 64]; suddenlyc = ""; for (suddenlyd = 0; suddenlyd < suddenlyb.leng...
