Remember that old saying: if you don’t know the source, don’t click it? With all these new URL shortening services, that advice seems to have been thrown out the window. As a result, evildoers are embracing the technology to disguise their malware sites behind shortened URLs.

This is obviously effective as an URL like hxxps://goo.gl/3BSi65 would have a much easier time getting past your spamfilter than say something like hxxp://h4x0r.tld/inject.aspx
