The Microsoft Tax: Critical flaw lets hackers take remote control of Windows PCs; Mac unaffected

Apple Online Store“An emergency Windows software update will close a loophole in Microsoft’s operating system that makes it easy for hackers to take control of a computer using shortcuts,” Claudine Beaumont reports for The Independent.

“Microsoft has confirmed that it will release an emergency, ‘out of band’ patch to close a loophole that made it easy for hackers and cyber criminals to gain remote access to PCs,” Beaumont reports. “The software update will patch a vulnerability in the way Windows XP, Windows Vista and Windows 7 handle shortcuts, also known as .lnk files.”

Beaumont reports, “Microsoft said it had seen a significant ‘increase in attempts’ by hackers over the last few days to take advantage of the loophole, which enables them to take control of a computer by tricking users in to clicking on infected shortcut links.”

  1. It is great to be one of the Mac users that is not *directly* affected, although we all pay a Microsoft tax in one way or another. For instance, the spam from the Windows botnets that plagues us all.

    But do not get complacent. Secure is not invulnerable. Be careful to avoid the phishing and trojan attacks and keep your OS and applications updated, and your Mac stands a very good chance of remaining malware-free. Eventually hackers will likely find a hole or two to exploit, but that won’t be the end of the world. It will just be reality stepping in for a brief visit.

  2. Anybody that pay’s taxes is paying the “Microsoft Tax”, every time this happens every agency in the US Government (except some covert operations that do not use Windows) has to make updates not to mention unnamed sums of money lost thru espionage.

  3. Whoa. That’s a whole mess of related articles. I don’t think I’ve ever seen so many attached to one story before.

    To be fair, has anyone successfully used this vulnerability successfully? If not, we should lay off, because we all defend Apple when there’s an un-exploited vulnerability discovered.

  4. I wouldn’t be crowing too loud about this one, not when iphones can get taken over with a malformed pdf file. Oh you can cry about adobe or safari being the cause, but if that’s all it takes to get owned, you have a serious problem.

    kind of like having microsoft

  5. I agree with Christian. We cannot make fun of windows for having an exploitable flaw when our iOS devices are wide open to a completely compromising security vulnerability. It has almost been a week since it went very very public, and even though Apple says they have the fix ready, they still haven’t released it! That’s something to write about.

  6. @aka Christian: “To be fair, has anyone successfully used this vulnerability successfully? If not, we should lay off, because we all defend Apple when there’s an un-exploited vulnerability discovered.”

    For the last 2 weeks I have had to deal with a Windows desktop at work with the default Windows error icon for every shortcut and task bar item because our crack IT security team felt it necessary to turn off all icon .lnk files. Whether this vulnerability has been taken advantage of or not it has created a huge PITA for everyone at my company for a couple of weeks now. I have probably a hundred shortcuts to vital files and applications on my desktop, all of which are pretty much useless right now.

    The so-called vulnerabilities associated with OS X have not caused me such problems. They are transparent to me and I’ve never had so much as a malware issue on my Macs.

  7. @Shadow/Maconymous: Please try to separate your FUD postings by at least a few minutes. It becomes obvious from the timing, subject matter, and writing style that you’re the same person.

    That said, let’s compare apples to apples. Yes, there seems to be an obscure and as yet unexploited vulnerability in some applications under iOS. Comparing that to the abject victimization of a full blown computer operating system is silly. Compare iOS to other mobile OSs. K-Mart is selling a tablet with a pirated version of Android off the shelf at retail! Windows can’t display shortcut icons! Get real.

    I only post under one name, as I believe it is against MDN policy to use multiples, which gets you banned.

    As for you trying to compare apples to apples, you failed. Internet explorer holes, for example, that allow exploits to get root access to windows are no different than safari holes that allow exploits to gain root access to idevices. And by the way, this flaw has been exploited, very publicly, but luckily for a benevolent (if one can say so) way.

    I am an owner of iPod, iPhone, and iPad, and I find it silly and ignorant that people are quick to judge other OS flaws, when we are just as affected today until apple finally comes out with a patch. I’m not spreading FUD as you suggest, just calling out some ingorance.

  9. it’s amazing the blogsphere makes a big deal every time some security company reports Macs have “more” vulnerabilities than Windows based on some counting of practically unusable flaws, but constantly shrugs off worst-case zero-day vulnerabilities like this that pop up several times a year for Windows. call it Stockholm Syndrome or just bias, it makes it obvious what gasbags most of them are.

    Windows is hopeless. even Windows 7, which was supposed to end these exploits. unless and until MS re-writes the entire OS code from the ground up (which it never will) it will always be riddled with holes like swiss cheese.

    the iOS PDF flaw is irrelevant, dude. get a sense of proportion. the millions of ‘bots that are spamming the world with trillions of junk hits are running on Windows. Apple is not invulnerable, but it has won its security war over the years. MS has not just lost that war, it has endangered the whole planet in the process.

  10. @ John

    I agree with most of what you say, except for one thing: that this iOS flaw is irrelevant.

    Any exploit, I don’t care on what device or OS that one may use, that is publicly known to allow complete control over one’s device without one’s express permission, or even awareness, is completely relevant and critical to the person being exploitable. Since iPhones now hold as much personal and financial info as PCs and Macs, any such flaw on any device or computer is of great concern to the people vulnerable to it. To say otherwise is irresponsible.

    I hear you on the point that windows has (too) many of them hindering usability and productivity. But I’m sure you will agree that any device flaw that can be exploited to negatively affect you is very relevant to you.

  11. but it’s not all about me. it’s the big picture that counts more. all OS’s have vulnerabilities. but OS X (and cousin Linux, both branches of the UNIX tree) and its variants are generally difficult to attack with practically useful success at scale, while Windows is generally road kill. it is simply wrong to equate the two situations in any way.

    iOS is also just 3 years old. it takes time to find the vulnerabilities. Windows is 15 years old. it should be fixed by now. it ain’t.

  12. @ Maconymous,

    This one iOS exploit, as you call it, was done with direct control of the piece of hardware that was infected, a la a Black Hat Mac exploit. In other words, it was just another Trojan, not an external attack.

    Tell me how the bad guys are going to get me to download an infected PDF.

    I’m waiting!

    While I’m waiting, someone is stealing your Credit Card info off of your Wonderful Windows 7 PC without you downloading a frigging thing.

    They are both similar exploits my ass.

  13. @AI

    First, I don’t own a PC, but an iMac (as well as all other idevices). Your personal attack is really unwarranted, very presumptive, and your use of colorful language to express a faulty point is childish, probably because you are trying to downplay or deny what you know is an obvious and serious exploit (a description acceptable by any reasonable technologically-savvy person) that has unfortunately surfaced on an Apple device.

    Second, if you had followed the news on how this exploit works, you would know that you never need to click on a link to a PDF. All it takes is a swipe of a menu item or flipping a switch or interacting with any unsuspecting GUI element on a mobile webpage to install anything. I am guessing on this, but I suspect that one can probably automate this interaction on a malicious page that completes this action automatically just by you visiting it, without warning. That is why this is serious.

    I have no problems with people who are Apple fanboys, as am I to some extent, believe it or not. What really bothers me is ignorance, arrogance, and unreasonableness to which this leads in some posters’ comments here and elsewhere. I am not defending Windows by any means. I am just saying that people who are downplaying this serious exploit just because it’s on an Apple device are irrational, and those who make fun of windows at the same time are hypocrites.

    I don’t want another password to remember. ” width=”19″ height=”19″ alt=”smile” style=”border:0;” />

    I’m sure MDN tracks IPs to prevent abuse by using different usernames. Besides, if you look at the history of my posts, you will see that I have asked for help or advice with my idevices, offered productive projections on where I see Apple as going in the future, and also criticized them when I feel they need it. To label me as FUD would therefore be very presumptive, just based on my comments to this post. Even in my posts here, I am not criticizing Apple here, just pointing out the irrational and hypocritical reactions and comments to the posters.

  15. If an exploit is discovered in Windows XP, Vista or 7, should Mac or iOS users be concerned about that the same exploit?

    No. These operating systems are vastly different. A venerability in Windows has absolutely no relevance to the UNIX based Mac or iOS.

  16. @Maconymous.

    “First, I don’t own a PC, but an iMac…”
    “I don’t want another password to remember”.

    A Mac without keychain must be very rare indeed. Don’t ever sell your machine.
