back to article 550,000-strong army of Mac zombies spreads across world

The Mac-specific Flashback Trojan created a zombie army of 550,000 Mac machines by exploiting a Java hole that Apple only patched on Tuesday, six weeks after Microsoft plugged it up on Windows machines. This is according to Russian anti-virus firm Dr Web, which arrived at the figure after it successfully managed to sinkhole …

        I had a crocodile pie once and it was more like flavourless haddock than chicken.

        Of course it is possible I had a haddock pie and some Aussie pie flogger had a giggle at my expense.

        My recollections of crocodile meat, from when Sainsburys sold it as precut strips, around 1998 or so, I think, are:

        1. It has a distinct texture that vaguely looked like it would go in flakes (like white fish does) as I cooked it, but was meat-like rather than fish-like, and didn't flake at all. The texture was more like beef or lamb than it was like chicken.

        2. It was nearly white in colour, which added to its resemblance to fish.

        3. It had distinct, but not particularly strong, flavour that was not very much like chicken.

        Most of that time I have surfed with Javascript disabled. That fended off quite a few threats in the early years.

        I also avoid installing any antivirus products. They lead to a false sense of security. Case in point: I've helped people clear trojans that their AV software only managed to pick up on after quite some time (I kept a sample at work where we are forced to use AV software).

        OSX has grown in popularity. Welcome to your worst nightmare.

                I figured that out after about four or five years of struggling with Virex, and pretty much everything from Norton or McAfee. Also, by that time (early '90s), the Web was just starting to become widespread, and so there was a whole new set of common-sense do's and don'ts for how to handle things like Java, JavaScript and unsolicited downloads, not to mention all the attention of malware authors seemingly shifting to Windows. Back then, I was still using a scanner to check my downloads for viruses, but I'd ditched my automatic self-running AV suite -- the stuff that would run at boot time, and barge in to check every file I opened -- because it was slowing my system to a crawl and was getting to be a bigger pain in the ass than it was worth.

            "erm you have to type in your admin password for it to install"

            Actually, you don't.

            It's a bit of an odd duck, this one. It asks you for an administrator password, but you don't actually have to type it.

            When the malicious Java applet runs, it attempts to download additional code. To do this, it prompts the user for an administrator password. If the user is gullible enough to type it, the downloader installs a payload in the Mac's Applications folder, and (I believe) sets it to run automatically at startup.

            If the user *doesn't* type the administration password, the downloader installs a hostile payload in the user's home folder. This payload runs in userland, without administrator privileges, and I'm not certain but I don't believe it runs on restart (and it certainly doesn't if the user restarts and logs in to a different account). It's a lot more limited in what it can do, but it does still run, and (if the user doesn't have the firewall enabled) does seem to have the capability of making outside connections.

            So the upshot is: No, you don't have to type an admin password. If you don't, the infection is somewhat mitigated, but it is still effective.

      I've been a "true believer" since '85 and, iirc, one of the first major viruses discovered in the wild -- or at least the first that got any media attention -- was a Mac virus, around 1988 or '89.

      I won't speak for other "fanbois" -- jeezus, I hate that goddamn' word -- but one of the first things I learned twenty-odd years ago was to not be complacent. I still think criticism of Windows for its defaults being set to "hack me, root me, trojan me, pwn me" out of the box, but I've always paid close attention to virus/malware reporting in the Reg and elsewhere as I knew sooner or later some miscreants would get around to doing a Mac virus or trojan, and I wanted to be sure I was ready for them (Firefox/NoScript/Adblock/Flashblock/LittleSnitch FTW).

          Thanks. The first computer I ever used or owned was a Mac; the design shop I was working got some in early '85, and I bought my own shortly after that. I think that if I'd used any system other than a Mac, I would be totally fearing and hating computers now. As it was, I was able to explore and experiment and learn about how computers and networks work because the Mac "just worked"; I could concentrate on my work and on self-education with my computer because I wasn't spending half the day ripping my hair out trying to figure out why stuff wasn't working.

          But, aaaa-aaaanyway... long story short... yeah, I hate being tagged as a "fanboi" because I've used a Mac for over 20 years and really like it, but I can still dig where people are coming from when they fling that word around whenever I glance at the TV and see all those goddamn' hipsters lining up at 3:00 in the goddamn' morning to pay too much for iPhones and iPads... and I catch myself mumbling "jeezus, what a bunch of fanbois!"

        In my circles, there is about 1 Mac user for every 50 Windows user. True, it would not be hard for me to find an infected Windows machine, but it is because I know which particular user is most likely to have an infection at any given time. (OTOH maybe he has cleaned up his act by now, in that case I'd be hard pressed to find an infected Windows machine)

Possible reasons of going against such practices might be either recent switch from Windows, or a low IQ.

    Serious question - no Apple or Java bashing here. Why is it that Apple manage the Java updates for OSX when Oracle do them for Windows and Linux? From what I've read it seems Apple would prefer Oracle to do this, but how did they get into this situation in the first place?

    1. ThomH

      Re: Why...?

      As part of their desperate attempts to become relevant again c.1999, Apple built Java directly into OS X and made it an on-the-box feature. The OS hence not only could run standard Java apps exactly as if they were native but included a rich set of bindings so that you could write fully native apps directly with the native frameworks but in Java. Per its designers, Java descends more from Objective-C than from C++ so I guess Apple were positioning themselves to be able to go fully Java if the market embraced it, hence they needed direct control over the thing.

      In the end the market chose Objective-C (though revisionists don't seem to remember it this way), Apple worked on advancing that and deprecated the native Java bindings after only a few versions and dumped the default inclusion of the Java runtime at all as of the current version. Cyberduck is the only big OS X app I'm aware of with a Java core, Neooffice/J having once also been quite popular but probably not so much since Open/LibreOffice went native.

      It was quite stupid that Apple were still maintaining Java separately and more slowly, and this is exactly the sort of flaw that doing so has exposed. So it's good that they don't do that any more, though it's far from being Apple's only security problem.

    I'm currently vulnerable to this, as my main install of Java is a bit out of date, but updating it on Windows, when you run as an user, is a pain - even if you authenticate as admin, it fails with a folder creation error, so you have to log out, login as Admin...yeah, I'm lazy.

    But not only that - a lot of programs that rely on Java (e.g. SPSS/PASW) use their own JVM to ensure that it is compatible, and these never get updated, which is a bit of a security hole...

          So lets examine you English skills

          Where in the advert does it say that Macs can't get a virus? - It doesn't, Not even once.

          They'r clearly talking about a Windows Virus. Which a Mac cannot get. Yes, they can pass them on.

          So you're original comment "they told me Apple computers didn't get viruses!" is actually completely wrong. They never said it at all.

          English may be your first language, but you're not very good at it. Stick to picture books

    I've noticed a distinct dislike of Mac users on El Reg, nothing wrong with that, anyone who spends double the value because it has a customised version of linux on it deserves to be mocked. I mean really, I've tried using a mac, honestly I have. But its just terrible. Shame Microsoft is trying to copy them now.

    "exploiting a Java hole that Apple only patched on Tuesday"

    Er, Apple aren't maintaining Java for OS X on their own. As your own article states, Oracle are involved in this release too.

    Apple are no more interested in keeping Java limping along than they are in supporting Flash on iOS. Both are obsolete technologies that have lasted well beyond their Use By date.

      What bit of "only runs on OS X 10.7" did you not understand?

  20. Wyrdness

    After checking that my Mac was clean, I thought that I'd see which version of Java is installed. So I typed java -version into bash. The result was:

    No Java runtime present, requesting install.

    Needless to say, I clicked cancel when it asked me if I wanted to install Java. So unless a user has explicitly installed Java on their Mac, then they're safe (this time).

    Nice to see El Reg forums maintaining their usual standards...

    For anyone interested, instructions on checking for and removing the malware are here :-

    The only observation I would make is that, of the number of active OSX computers in use (given the sales of OS updates & etc), 500,000 is actually quite a small percentage. So they've got off lightly, basically.

    Anyway a Trojan isn't even a Virus. Plus it's Javas fault, not Apples. and anyway Windows had viruses first.

      How do you know you NEVER, repeat NEVER, got a virus? Every Mac user I've come across in the last 20 years, has refused to install any Antivirus, therefore wouldn't actually know if they had got a Virus.

        ...then you haven't come across very many Mac users then, have you?

        Every Mac user I know (including me) has AV installed - if only to avoid inadvertently forwarding a Windows virus to a windows-using friend.

        Shock! Horror!

        Some of us Mac users DO have friends who use Windows - and we STILL talk to each other and remain friends...

        You may write as many viruses as you want. More interesting is how much chances they will have to infect and spread outside of the lab. For this matter count those viruses for *nix that have been allegedly detected in the wild along with the percentages.

        AMOF, This case shows that:

        1) Java runtime is a pretty dangerous technology to be allowed in a web browser, nothing to say it is almost always redundant stuff

        ...depends on how you define "thousands". I did once end up cleaning a computer that had well over 100,000 running copies of the same worm, each with its own executable in c:\windows\system. "Slow" doesn't begin to describe it.

          I didn't have to clean it up, but our Sr. Tech did.

          Back in the early virus fighting days, Sr. Pilot fish installed really good AV that you can't get anymore (It didn't even trust updates it downloaded itself, and unless you'd granted explicit permissions to directories you couldn't write there either) on server for a client. Client got a virus. Virus said you the system was infected and could be cleaned, but the AV needed to be turned off first. AV was configured to quarantine, not delete and had been running for over a year catching many, many viruses and stopping them from infecting the system. Client dutifully turned off AV and proceeded to "clean" the infection. Which of course released EVERY virus from the quarantine.

          I was so glad I wasn't Sr. Tech that day.

    Please, stop arguing :)

    I have a Windows desktop with a Linux (Mint) VM, an iPhone and an iPad. I don't want viruses on any of my things!

    Arguments as to which is intrinsically safer are usually correct insofar as the history of Windows is that of a totally insecure OS having to evolve into a more secure one, leaving plenty of holes behind, coupled with the fact that it's by far the most common OS on desktops.

    I honestly don't think any of them are secure against the combination of determined attacker and non-expert users. My advice to anyone and everyone is to store anything important, encrypted, onto a memory key that you only plug in when you need it, never run as Administrator, use complex 128 or 256 bit passwords for all of your online banking activity, which you store in something like a KeePass .db (as there's no way you'll be able to remember them!), saved onto your encrypted memory key and try not to visit dodgy websites!

    I don't think you can do much more than that other than unplug your system from the internet or switching it off, whatever OS it is.

      For the truly paranoid among us, simply boot from a Fedora "Live" CD or usb stick for banking transactions, or reserve a notebook exclusively for banking, rebooting before use.

      This should guarantee a safe connection to your bank, free of any keyloggers, worms, viruses or trojans.

    Exactly! As soon as personal Mac and Unix boxes number the same as Windows on the interwebs, the virus writers will take note, and they will succeed too. Macs or Unix are not really more secure, just not as interesting or numerous to be worth it yet.

      I'm a Windows users, but I recognize that Linux and Mac (BSD) are actually inherently more secure than my preferred OS, but, and this is a BIG but, any time you dwadle with patches for known security vulnerabilities, the malware bastages are likely to run by and give you drop your drawers. If you look completely oblivious they may even tie your shoelaces together before they drop your drawers. And the Fanbois* have been completely oblivious for the last few years.

    "The Flashback malware was capable of installing itself on unprotected Mac machines without user interaction, ... Users become infected simply by visiting a site loaded with exploit code, ..."

    Another month and another shock virus claim...

    Symantec list this as a very low risk, it's been around for months. it does require a level of social engineering, you choose to download it and then choose to ignore a system warning about it being downloaded, and then if you give it the users password it installs. Most macs have the root account disabled and essentially rely on sudo. The latest release, as mentioned, does not require the password to do a limited install. which presumably means you'll be warned whenever it tries to install it's downloaded payload.

    Hopefully Oracle will roll the osx release into their main release cycle soon, Java has been depracated on osx since 2010 and has been in the process of being redacted into the main release ever since.

    Macs, like Linux, aren't virus immune. But both are a harder target.

    Anti Virus

    It looks like just having antivirus apps installed means the app self deletes, presumably to hide how far its impregnated. I had AV on my mac for 3 years now and glad of it, anyone who doesn't install antivirus apps on their machines and im including linux guys on this is doing the equivalent of having unprotected sex with as many different people as possible, and not bothering with an STD test the day after.

    Also now apple have relinquished control of how java is ported to their machines and it is the responsibility of the open jdk project hopefully security hole fixes will be quicker.
