Switchback is one very clever virus, but it's having a hard time distributing itself, so most of the world doesn't even know it exists.

For a start, it can only infect Macs running OS?X 1.2.5 or 1.2.6 (it's possible that 10.2.7 could be infected as well, although we haven't heard about infections from any G5 owners yet). So out of 25-30 million Mac users, maybe 7-8 million tops are using the right version of OS?X.

Then they have to be using Safari 1.0 and visit a site displaying affiliate ads for XGeeks.com. Although these ads are presented as linking to a hot new mail order company specializing on OS?X, that's just a cover. Their prices are just high enough to keep people from ordering, but the commission rate is enough to get every Mac webmaster interested enough to sign up for the program.

The ads aren't simple animated GIFs; they're JavaScript programs that install an AppleScript on the user's OS?X Macintosh. When this AppleScript is run (it autoruns a few minutes after startup), it accesses your Address Book through Mail and sends itself to the first 100 users who have "mac" somewhere in their email address. The email offers recipients a 15% discount on their first order through XGeeks.com.

That's the clever part. They try to target just Mac users, and when they visit the XGeeks site, they get infected -- assuming they're running the right version of OS?X and Safari 1.0. And Switchback then propagates itself again, assuming the visitor has Mail configured on their computer.

Considering the size of the OS X installed base, the number of Safari 1.0 downloads, and the number of OS?X users who use Mail rather than something else, we estimate that this virus could potentially infect 5,000 to 20,000 users. And it could take months to reach that level, since OS?X users don't restart nearly as often as Windows or classic Mac OS users.

It's only a start, but this is the first OS?X virus ever, so everyone should try to get their hands on a copy to see what makes it tick. The next X-virus might actually do something malicious. Consider Switchback a proof of concept that almost sorta works.

Of course, with the latest Window worm on the rampage, nobody but the Lite Side staff has even noticed Switchback.

And why is it called Switchback? Because when you read the source code, the first comment calls OS?X users to give up their nonconformity and switch back to Microsoft Windows.

perhaps i should have actually posted this over in the humour forum

OSX has never been virus free, I has just been less prone to viruses.

"virus free" means no viruses are known to exits.

"virus prone" means that it is possible to write a virus for it.

While OS X has pretty much been "virus free", I doubt any OS is ever going to not be "virus prone".

    • Ocenaudio 3.19.5

      By Copernic · Posted

      Ocenaudio 3.19.5 by Razvan Serea  Ocenaudio is a full featured, fast and easy to use audio and music editor. It is the ideal software for people who need to edit and analyze audio files without complications. Ocenaudio also has powerful features that will please more advanced users. To assist ocenaudio development, a powerful toolset of audio editing, analysis and manipulation called Ocen Framework was created. ocenaudio is also based on Qt framework, a well known library for cross-platform development. Cross-platform support ocenaudio is available for all major operating systems: Microsoft Windows, Mac OS X and Linux. Native applications are generated for each platform from a common source, in order to achieve excelent performance and seamless integration with the operating system. All versions of ocenaudio have a uniform set of features and the same graphical interface, so the skills you learn in one platform can be used in the others. VST plugins support Ocenaudio supports VST (Virtual Studio Technology) plugins, giving its users access to numerous effects. Like the native effects, VST effects can use real-time preview to aide configuration. Real-time preview of effects Applying effects such as EQ, gain and filtering is an important part of audio editing. However, it is very tricky to get the desired result by adjusting the controls configuration alone: you must listen the processed audio. To ease the configuration of audio effects, ocenaudio has a real time preview feature: you hear the processed signal while adjusting the controls. The effect configuration window also includes a miniature view of the selected audio signal. You can navigate on this miniature view in the same way as you do on the main interface, selecting parts that interest you and listening to the effect result in real time. Multiselection for delicate editions To speed up complex audio files editing, ocenaudio includes multi-selection. With this amazing tool, you can simultaneously select different portions of an audio file and listen, edit or even apply an effect to them. For example, if you want to normalize only the excerpts of an interview where the interviewee is talking, just select them and apply the effect. Eficient edition of large files With ocenaudio, there is no limit to the length or the quantity of the audio files you can edit. Using an advanced memory management system, the application keeps your files open without wasting any of your computer's memory. Even in files several hours long, common editing operations such as copy, cut or paste happen almost instantly. Fully featured spectrogram Besides offering an incredible waveform view of your audio files, ocenaudio has a powerful and complete spectrogram view. In this view, you can analyze the spectral content of your audio signal with maximum clarity. Advanced users will be surprised to find that the spectrogram settings are applied in real time. The display is updated immediately when altering features such as the number of frequency bands, window type and size and dynamic range of the display. Ocenaudio 3.19.5 changelog: Fixes crashes related to audio devices on Windows (DirectSound and ASIO) Fixes several crashes and memory corruption issues Fixes opening several headerless files at once, which previously dropped all but one Improves batch export by suggesting and remembering the destination folder Fixes accented and non-Latin characters in VST plug-in and compressed-archive file names Adds zstd compression support and updates the archive library Other bug fixes and improvements Download: Ocenaudio 64-bit | Portable | ~40.0 MB (Freeware) Download: Ocenaudio for Linux and Mac OS View: Ocenaudio Homepage | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
    • Limited Prime Day deal sees Amazon Echo Show 11 is at its lowest price yet

      By ad47uk · Posted

      I did think about a Echo show once and it would be useful to see what my cameras see. But my brother got one and I changed my mind. Adverts and not really worth the price just to see my cameras. I have a load of dots and a Echo Gen 4, they will do.
    • The Trump administration doesn't want you to use OpenAI's GPT-5.6 without its approval

      I asking where you are from or live, because if you don't live in the U.K, why are you so bothered? That is another reason I voted out, E.U and people poking their noses in where they should not be. Sadly we still have it, Trump, and his cronies. Putin as well and no doubt others. It makes no difference what we believe, if we made the right choice or not, we are out. As I said to someone when the news first broke we have voted out, we just need to make the best of it. I have no problems with closer ties to the E.U, we still need to trade. Just don't want to be in their club.

      So you think I voted out because i am anti-immigrant. I am fed up with those that come over and think that we owe them something. The ones that are at the moment coming over from France where they are already in a safe country because they think and no doubt will get everything chucked at them. While people who were born and bred here get very little. I have nothing against as i have said before those that come here and work. In fact I know full well that our NHS would struggle without them. I do have a problem with those that come over here and try to push their religion and their way of life onto us. My reasons for voting out was because of what the E.U is and is also becoming. I did not agree with Freedom of movement, not because I don't want people over here, but because people need to be checked before being allowed to cross borders and that goes both ways. But my main thing was because the E.U is becoming if not already a united states of Europe. The only reason countries like Poland and Romania joined was because they had no money. When my partner left Poland, she had nothing, Poland had nothing, that is why she left. Wanted to learn something and earn a living. The E.U would have us back according to Michel Barnier. https://www.euronews.com/my-eu...ator-barnier-tells-euronews Why are you so scared to say what country you are in?
