Trailrunner7 writes, quoting Threat Post: "Security researchers have come across a worm that is meant specifically to steal blueprints, design documents and other files created with the AutoCAD software. The worm, known as ACAD/Medre.A, is spreading through infected AutoCAD templates and is sending tens of thousands of stolen documents to email addresses in China. However, experts say that the worm's infection rates are dropping at this point and it doesn't seem to be part of a targeted attack campaign. ... [They] discovered that not only was the worm highly customized and well-constructed, it seemed to be targeting mostly machines in Peru for some reason. ... They found that ACAD/Medre.A was written in AutoLISP, a specialized version of the LISP scripting language that's used in AutoCAD."
