Pump and Dumpers try PDFs

Source: Sophos
Sophos reports that they've now seen pump and dump spam using PDF attachments instead of images. Pump and dump spam was an early adopter of text-as-images, and this technique may be picked up by other spammers, such as the job scam crowd. It's not too hard to extract plain text from a PDF, but obfuscation techniques are possible.
