Computer 'Worms' Turn on Macs

Carl Bialik from WSJ writes "Macs have been laregly immune to the viruses, worms and malware that have plagued PCs, but the Mac's recent popularity uptick has meant that 'bad guys appear to be casing the joint,' the Wall Street Journal reports. Among the signs: two recently discovered worms and the discovery of a vulnerability in Mac OS X that leaves Safari open to a hack. A Symantec engineer predicts a 'gradual erosion' of the idea that Macs are a safer operating system than Windows. 'Some security experts believe hackers are becoming more interested in writing nasty code for Macs precisely because of reports of its relative immunity to security woes,' the WSJ reports. 'Apple itself has gone out of its way not to promote the Mac's relative safety, lest it tempt hackers to prove the company wrong. Apple declined to discuss the topic of security in depth for this article.'"

      One of the recent worms relies on iChat.

      I use iChat every day, and have other Mac users on my "Buddies" list, yet I've still yet to get this particular worm delivered to me, and it's been well over a week since I heard about it being "in the wild." There was even a story about it over on Drudge, so somebody must have been hit by it, right? Yet, I still have yet to hear a first-person account of somebody getting this particular worm sent to them.

      Part of the reason for this might be that the Mac gives all kinds of warnings about the nature of incoming files, and even requires that you type in your admin password before running anything that hits any important part of the OS. (Hint: just installing an application or performing trivial tasks does not require a password. Whenever you get a password prompt on a Mac, you know that the app in question is trying to do something which requires root-level access.)

      Installing antivirus software on a Mac is worse than useless. Should a virus ever come along which can get past both MacOS security and simple user awareness, currently-existing anitvirus software won't be ready for it anyway.

      Plus, I know enough from running antivirus software on my Windows PC at work (which I would never DARE go without) that anitvirus software means a performance hit and less stability of the operating system.

      I think I'll just stick with common sense and Apple's frequent OS update patches.

      Unlike Windows, it's perfectly safe to run full-time as the "Administrator" user, and nearly every OS X user does.
      It's mostly safe, not perfectly safe. The iChat virus/trojan suggests one reason why. Since an admin has free access to /Applications, a bug running under that user's permissions can modify apps in that folder, helping the bug to spread itself either locally (next time another user on the machine opens an infected app) or remotely (e.g. via a modified iChat). A second reason is that admin users can sudo with their own password. If the admin account's password is compromised by a bug or hacker, root control of the machine goes with it. This is not the same as running as root, like Windows admins do, and viruses running under the admin user's permissions do not have root access. A regular user must enter an admin's username/password to sudo, making the virus/hacker's job more complicated.

      Nearly ever OS X user on a single-person machine runs as admin, and that's what Apple sets up by default. But it's not a bad idea to reocnsider.

      How hard would it be to convince some average uses that the worm/virus/trojan that they're downloading is actually an amazing tool to "tweak" some aspect of their computer's performance (internet/speed/ram/etc...)?

      The difference between the security hole approach and the social engineering approach, is that the latter starts and ends with stupid users. The worm cannot force its way onto the computers of more savy users like the RPC worms in Windows did. Instead, it will set off a huge number of warning flags with more experienced users, and perhaps prompt them to take action to clean other user's computers or encourage them not to run anything that asks for their password.

      The end result is that such viruses could not spread as fast or as far as their Windows counterparts.

      I don't get it. I tried running the "rm -rf /" script, and got nothing. I tried it again as root. It just sat there and worked patiently for a few minutes before returning a prompt. Was it supposed to do something cool? If so, maybe I should have run it on a desktop instead of the production server? Any hints at what I did wrong?

      Maybe I should try it on my Windows machine next? Shouldn't I type "C:\" instead? Or, is this script not that portable?

    Windows has had what, like 200,000 Virus's in the last year? Apple has had two or three theoretical exploits that either require the user to run code by hand or else target services that most mac users don't turn on. Sounds like Apple is doing its job to me. And honestly this idea that as Apple gets more popular there will be more viruses is largely a load of crap. The notoriety of writing the first real virus for OS X would be vastly more than for writing yet another windows virus. The reason why no one writes viruses for Apple is most likely because people like Apple and want them to succeed. I think if people start writing viruses for Apple it will be because Apple gets lazy and stops innovating, or else stops at least trying to fix the bugs in its software. Because right now both the means and the motive or there, but it's just not really happening.

  5. It's not that Mac OS X is "virus-proof" by jht · · Score: 4, Insightful

    It's never been that (at least for most people). The advantage of Mac OS X is that it is less vulnerable than Windows (making Windows an easier target), and that Apple made decisions in the design process that mean that the typical consequences of a flaw are less severe. In recent years, Microsoft has attempted to harden Windows further and reduce their exposure - in W2K3 Server, for instance, they've done a pretty good job of it.

    Even if Apple magically pulls some sort of super OS-jujitsu that reverses their market share and Microsoft's, the basic architecture will stay the same underneath - and that means Apple will have their relative advantages intact for the foreseeable future. Windows is, as its heart, an OS that has traded off many security options for ease of access and ease of programming. Apple had the advantage of seeing what was already happening to Windows when they made their decisions about how OS X would be designed, plus the system it was derived from was pretty robust to begin with.

    There will be viruses that attack Mac OS X. Some will do a pretty good job of attacking. I'm kind of surprised it's taken this long to get there. But I'm also not expecting it ever to compare to Windows in that regard.

    A recent columnist at Wired said what I was thinking already:

    From the linked article:

    "These Mac security holes are a storm in a teacup. They've inspired hundreds of stories in the press and even the national network news, but if they were Windows holes, no one would have blinked.

    That's because holes in Windows are routine, business as usual, while it now appears the Mac is under attack thanks to Apple's brand-new high profile. But this isn't the case.

    Last month, there were four "massive" virus attacks on Windows, according to Commtouch, an antispam and antivirus vendor. Indeed, viruses are now so aggressive, they routinely outpace attempts by antivirus companies to distribute protective signatures.

    This state of affairs is now so common, I hadn't noticed -- and I work for a technology news site. "Virulent computer virus infects millions worldwide, other non-news at 11."

    These Mac "threats" are only news because of their novelty, not the threat level they pose."

    The reason why no one writes viruses for Apple is most likely because people like Apple and want them to succeed.

    Considering that the main incentive for virus writers these days seems to be economic (profitable criminal activity such as spamming, phishing, DDOS blackmail, identity fraud), it seems unlikely to me that these criminals care if Apple succeeds. More likely, the profit motive isn't there, probably a result the combination of greater security on OSX, and smaller installed base.

    Agreed: If you want Mac malware, you have to go to a store and buy it.

    It's completely unacceptable that Slashdot editors would post this garbage. From the referenced article:

    "In the past two weeks, information-security companies like Symantec Inc., Sophos PLC and McAfee Inc. have identified several security issues related to the latest version of Apple's Mac operating system, called OS X. Among the concerns: two "worms," programs written by unknown hackers that were designed to spread themselves to other Macs through Apple's iChat instant-messaging software and Bluetooth wireless-communications capability."

    Translation: Some public relations drone, with no technical knowledge, paid the Wall Street Journal to post the article. The Wall Street Journal is a "What the rich want you to think" publication, and, in my experience, usually unreliable for anything useful. Note that the article jumps from subject to subject rapidly, apparently to hide the fact that there are no actual incidents of Mac infections to report.

    Another translation: Symantec, a maker of very buggy security software of poor design, and other "security" companies want Mac users to buy their products.

    Some people, in my opinion, spend their entire working lives being dishonest, trying to trick other people. In my experience some of them work for WSJ.

    Now is it right for me to say that my linux computers are more secure just because they are running linux? No, that's stupid.

    Why is that stupid? There are real architectural, operational, testing, and implementation differences between Windows and Linux. Obviously one of them is more secure and less likely to be compromised than the other. There is nothing stupid about looking at those differences and at the track record of both OS's and making predictions and making usage decisions based upon that information. "They're all the same," is the argument of a lazy man or someone trying to justify a bad choice by trying to make all choices look equally bad.

    The same thing applies with this story - Macs can be exploited because that is the nature of the business. We usually find the holes because some numbnut exploits it.

    No one is arguing that Macs can't be exploited. They certainly can be and are. We do not, however, find most exploitable holes by seeing exploits in the wild. The majority of holes are discovered by developers coding the products. The next largest chunk are found by users and legitimate security researchers. Then a few are found when they are exploited in the wild by hackers. How many zero day exploits have their been for Linux or OS X? The answer is very, very few if any. There have been some for Windows, but most of the underlying vulnerabilities were probably discovered by MS, but they just did not get around to fixing them.

    Sure there will be exploits and even zero-day exploits for OS X, but they are just not likely to spread widely or be much of a problem for the average user. If they are a large threat they will be well-known and quickly fixed. A major worm for OS X would be news and it would be unusual. For Windows it is business as usual.

    But don't assume that just because no one has broken into your house yet that your house is completely secure.

    This is a very good analogy. My house is concrete block and was built with only glass block windows on the first floor. Actually the block is two thick on the first floor. Before I bought it, someone had wired a security system and outdoor flood lights. A few months back someone busted into my shed, but ran off without getting anything. The items in my shed are relatively large an not all that valuable.

    I'd say that is a good analogy for OS X. It is built with security in mind on well tested, industrial grade framework. They have added onto it and made it more secure in some ways and less secure in others, but it will likely never be as insecure as the neighbor's ranch style place with two plate glass doors and a key under the mat that you see the kids get out every day.

    OS X had someone break into the shed (try to distribute a trojan) but nothing has been taken. It is a good sign that maybe Apple and OS X users should be paying attention and maybe doing some more security reviews, but it is in no way comparable to the apartment complex down the street that have been burgled at least once a month for several years and where we always hear about people getting shot.
