AutoCAD Worm Medre.A Stealing Designs, Blueprints 139

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."

      Well my copy of 2012 does, otherwise it won't work at all. I don't know if 2013 does. Maybe someone who's company has sprung for the new version can chime in.

          auto cad needs a better then video card what most vm have. Also can use a lot of cpu power.

            That entirely depends on what you do with it, it doesn't "need it" unless it is for a very large project (for CPU) and you want it to look very nice on the screen with 3D rendering.

              We designed cars in 1992 on Spark stations. Multi-surfaced wireframe models, in those days.

              It may have taken a second or two to redraw shaded views, but CPU speeds were never a real issue.

              The biggest problems back then were network problems. "Network going down!" was a common scream around the body design shop and everyone rushed to save their work.

              Solid modelling was done on the same Spark stations in 1999. Once again, no real problems with the hardware.

              • Solaris, where simple things like pressing the up arrow in the terminal don't work (or was it tab completion, one of the two, don't remember which).

                Solaris is like Linux, except that everything is a little worse.

                Maybe back in those days you mentioned it was good compared to the rest then... But maybe today it's still like it was in 1992 or so?

                  The lack of arrows and broken tab completion was a problem with ksh, no matter what Unix variant you ran it on. Ksh can be fixed to provide both features using some hacks in your kshrc, but they aren't obvious. Or, you can just use bash like you do on Linux.

                  Of course, the version of bash on Solaris 10 is ancient, but that's a consequence of the philosophy of "if it isn't broke, don't fix it." This philosophy pervades the entire toolchain and the core libraries. This focus on stability is great for serve

      also most Autodesk software needs local admin to run right or at least the older ver of it did.

      AutoCAD 2013 (and 2012, and at least a few more versions back) run fine without admin rights. It helps to have write permissions opened up on various AutoCad folders (Program Files\AutoDesk, ProgramData\Autodesk, etc.) to allow for customization, but the application will run fine. Admin rights are only needed at the time of initial installation.

      I cannot remember any version of AutoCAD (and I am started administrating AutoCAD systems from version 10) needing local admin rights to run. AutoCAD has been one of the few apps to support non-admin users as soon as windows enabled that feature (windows NT3.5 anyone?). Only if you seriously mess up your AutoCAD settings inside your user profile or the registry will this happen. Of course you're messing with those if you don't pay for the software you use...

        OK, don't feed the trolls, but here goes anyway:

        There's a bit of a difference: The AutoCAD drawings being stolen were (presumably) never meant to be released to the public. It could very well be theft, as in theft of trade-secret or such. Piracy never enters into it, as it's not a publicly-sold copyrighted work.

        You generally don't walk up to a engineering firm and ask to browse their drawings catalog and then offer to buy one. If you somehow did manage to buy a drawing, and if said drawing were copyrighted, and you then turned around and started selling copies of that drawing to others, then that would be piracy (and not theft).

        Theft of corporate secrets is indeed theft, since the original owners no longer have the secrets. The "secrecy" part of it is forever gone, even if the drawings remain. The economic loss is easily much, much greater than the corresponding loss due to piracy, namely of one potential sale of a copyrighted work that's otherwise generally available.

    A brand new install of Autocad costs $3,995 and up. It produces files that have a distinctive extension, making them easy to identify and to tell from other types of documents without even having to examine internal code. Any file produced by a legal autocad install was made by somebody who paid serious money to be able to do so. Ergo, if someone can harvest a thousand Autocad files at random, a high proportion of them will be of valuable, useful stuff.

            Fighting warez sites distributing Autocad means, if the company is successful, a higher percentage of the documents made with it will be the valuable stuff. At 4K a legitimate copy, actually stopping a high percentage of 'pirates' means increasing the danger to your own legitimate users.

              If going through 10,000 autocad documents means finding, say, a dozen new patent filings and diagrams, two trade secret process designs for million dollar product lines, a few archetectural blueprint packages, and such, it becomes worth a government paying a programming team to write the software and putting three or four fulltime engineers and a few technicians on just evaluating those documents for the 'good' ones. If there were a thousand bootleg copies of the software for every legitimate one, that government might not bother to go through 10 million documents for about the same haul, as most of the bootleg copies won't be producing anything worth that much.
