Is Mac OS as safe as ever?

Apple Computer fans have long loved to point out the safety of using Mac OS X, which has mostly been left to its own devices by hackers. But the arrival of three threats has some asking: Is the software's charmed security life over?

In the past two weeks, a pair of worms that target Mac OS X have been discovered, along with an easily exploitable, severe, security flaw. The vulnerability exposes Mac users to risks that are more familiar to Windows owners: the installation of malicious code through a bad Web site or e-mail.

While these represent a sea change, there is no need for Mac owners to worry, experts said, as the published attacks are still mainly theoretical and not widespread. But they caution that Apple fans should not be smug: Now that it's been done, other malicious code writers are likely to turn their attention to the operating system.

It's a "small step in malicious code development for OS X," said Kevin Long, an analyst at security specialist Cybertrust and a Mac user for 11 years. "The message we need to get out there is that Mac users should not be complacent."

While Microsoft Windows users have grown accustomed to a seemingly incessant stream of computer worms, viruses and security vulnerabilities, the same is not true for Mac owners. Going by forum postings, many Apple customers believe their system is much better protected against cyberattacks than the average Windows PC.

"Mac malware is not a myth. It is very real," said Kevin Finisterre, a security researcher at Digital Munition. Finisterre created the Inqtana worm, which targets Mac OS X and spreads using an 8- month-old vulnerability in Apple's Bluetooth software. "My point with Inqtana was to say, 'Hey! Wake up!'" he said.

Finisterre did not release his worm into the wild. He created Inqtana only to prove a point, and to encourage antivirus makers to update their products against malicious software using the same method of attack, he said. Furthermore, Inqtana was programmed so that it could never spread far.

"Go buy yourself some antivirus software, keep your Apple updates current and stop pretending that you are invincible, because you are not," Finisterre advised Mac users.

The risk for Apple system users grows slightly every day, Long said. The number of people using Macs is growing, which makes attacks more likely, he said. Some have suggested that Mac OS X's previous immunity to threats is due partly to malicious coders focusing on Microsoft products, which have a much larger user base and so bring a much bigger scope for impact.

"Many think that the Macintosh operating system is impervious to viruses or these kind of security threats. It is not that they are impervious; they are targeted less," said Craig Schmugar, virus research manager at McAfee.

"Don't need to freak out"
The events of the last two weeks could change that. Hackers have had their interest in Apple piqued, Finisterre said. "It is a semi-new frontier, so to speak," he said.

Even so, the incidents likely won't have any significant fallout, Long said. "Hopefully, the end result is that people are a little more careful. They don't need to freak out about this," he said.

Many Mac users seem unfazed. "I don't see myself changing any habits or panicking and running out to grab antivirus," CNET News.com reader Shane Walker wrote in an e-mail. "I am concerned, but not overly so. You just need to take the right precautions, watch your e-mail attachments and what you download like a hawk, and try to avoid known or seemingly questionable sites."

Another CNET News.com reader, using the initials J.G., said the three incidents don't bother him. "They are 'proof of concept,' not actual malware loose in the wild," the reader wrote in an e-mail. "I think much of the attention now being focused on Macs and OS X will dissipate in a few months."

So far, there have been no reports of any Mac systems infected with the Inqtana worm. The other OS X security incidents have had little impact on users either, experts said. Leap.A, considered to be the first first Mac operating system worm, was publicly posted on an online Mac message board, but did not make it onto many computers.

The most serious incident was perhaps the public disclosure of a serious and easily exploitable flaw in the Apple operating system, which could be a conduit for intruders to install malicious code on computers running the software. Attack code that takes advantage of the security hole was quickly posted on the Internet.

The problem lies in the way Mac OS X associates files with applications, and it could be exploited to hit a Mac via the Safari Web browser or Apple Mail, experts said. Apple has said it is working on a fix for the flaw. So far, no attacks based on the bug have been spotted on the Web.

Overall, only a few currently known worms, viruses and Trojans target the Mac, McAfee's Schmugar said. Nevertheless, people should not ignore the danger. "There does not have to be more then 150,000 threats for Macs before it's a security concern," he said, referring to the number of known Windows pests.

A machine running Apple's operating system might actually be easier to hit than a Windows PC, Schmugar said. "There are fewer and less evolved defenses around a Mac, because there have been fewer threats against it," he said. "The success rate for getting malicious code to run is probably greater."

The Mac maker is taking measures to sew up the latest hole in its operating system. "Apple takes security very seriously," a company representative said. "We're working on a fix so that this doesn't become something that could affect customers." The representative could not say when the patch would be ready.

Long recommends two tweaks to the OS X settings to make it more secure: enabling the firewall, and disabling the "Open safe files after downloading" option in the Safari preferences. That last option, if not locked up, could be exploited to trick people into downloading malicious code onto their Mac, he said.

All in all, this is not significant enough to dent user confidence in Mac OS X as a secure operating system, said Ray Wagner, an analyst at Gartner. "Given that the most recent vulnerability does not spawn an attack before being patched--an unknown--there is not enough impact on the average user to cause a significant change in behavior," he said.

Apple is advising its customers to consult its online safety guide, and to be cautious when surfing the Web. "Apple always advises Mac users to only accept files from vendors and Web sites that they know and trust," the company representative said.

Asked if the Mac, compared with Windows, is still the obvious safer choice for people on the Internet, Gartner's Wagner simply replied: "Yes."

Good article man, I figured it was only a matter of time that someone bothered to code a virus or two for the platfrom. My dad should take a peek at this, he often seems to flaunt the idea that security is never a problem for the OS.

 

Apple has taken a somewhat casual approach to security lately, so this is for the most part unsurprising. Apple was relying on their smaller market share and the obscurity of the Mac as a server platform to keep them relatively unscathed. For the most part it has been successful, but as they become more ubiquitous we will see more and more of this.

Before somebody draws a parallel to Linux, keep in mind that Unix/BSD/Linux has been the very framework of the Internet since its conception. It is already ubiquitous as a server OS, and still has no such issues.

 

Hail Linux!

 

An update on the Mac OS flaw(s): Patches have been released.

Source: CNET News

Apple Computer on Wednesday released a security update for Mac OS X that fixes 20 vulnerabilities, including a high-profile Web browser and Mail flaw disclosed last week.

The set of patches addresses a variety of security flaws, including several that could let an attacker gain control over a computer running the operating system software. The patch arrives after two weeks of intense scrutiny for Apple Mac OS X safety, prompted by the discovery of two worms and the disclosure of two security flaws in that period.

The Apple security update addresses those flaws, which affect the Safari Web browser and Apple Mail client. The vulnerabilities expose Mac users to risks that are more familiar to Windows owners: the installation of malicious code through a bad Web site or e-mail because of improper validation of downloads.

The update also changes iChat, Apple's instant messaging application, to thwart instant message threats such as the Leap.A pest, which was detected recently and attacked some Apple users.

"iChat now uses Download Validation to warn of unknown or unsafe file types during file transfers," Apple said.

Aside from the previously disclosed vulnerability in Safari, the Apple patch fixes four additional security bugs. These could result in code being executed on the user's machine after viewing a malicious Web site or allow JavaScript to execute in the local domain, Apple said in its update.

Other flaws fixed in the update include four issues related to the PHP scripted programming language, two problems related to Apple's Directory Services, a problem with mounting of file servers and a bug in FileVault secure storage, which was found to be insecure in the way a FileVault image is created.

Security Update 2006-001, can be downloaded and installed via the Software Update feature in Mac OS X or from Apple Downloads.

"Apple advises Mac OS X users to keep their system current by installing this and all Mac OS X software updates," the representative said.
