Image spammers doing the twist

It's been quite a while since I last blogged about ever changing image spam. Anna Vlasova wakens me from my unblogging slumber with some great samples of recent image spams were the spammer has decided to rotate the entire image to try to avoid detect. Take a look at this first one:

The spammer has really gone to town here:

• There's random speckling all over the images to upset hashing and OCR techniques
• There's no URL in the message itself (it's in the image)
• The entire image has been rotated to the left to obscure the text
  

And, of course, they are not going to be content with just one rotation and can randomize the angle per message:

And they've gone even further by slicing the image up, randomizing the angle and overlaying the elements using animation.
