Somthing Everybopdy Ought to Know About The Mac scareware

The fact that Mac users have fallen victim to "scareware" scams -- the kind that have long plagued Windows users -- shouldn't come as a surprise. After all, fake antivirus software schemes like MacDefender don't have to rely on exploitable vulnerabilities, but instead typically depend on tricking users into visiting malicious sites and duping them into installing the software.

And Mac users, for all their pretensions otherwise, are as fallible as the next person.

But from the news accounts this month about MacDefender, and the posts not only on Mac-specific blogs but also on ones usually devoted to Windows, you could be forgiven for thinking that Macs are suddenly the victims of choice.

They're not. Windows machines remain the most common target because, well, globally Windows PCs outnumber Mac OS by more than 16-to-1.

What is true is that Mac users now face the same scareware scams that Windows owners have had to deal with for years.

So what's the deal? Macpocalypse or not? And what should you watch for, and what can you do to keep safe?

Those are the questions we try to answer.

Is MacDefender a worm? Nope. Although MacDefender Dell latitude d630 battery and its ilk fall under the general term "malware" -- as in, it's malicious in some way -- it's not a virus, not a worm, not a true Trojan horse.

Instead, its one of a long line of "scareware" or "rogueware," terms that apply to fake -- hence "rogue" -- software that tries to spook you -- that's the "scare" -- into paying for a worthless program.

The labels are usually slapped on phony security software that claims a computer is heavily infected with worms, viruses and other malware. Such software nags users with pervasive pop-ups and fake alerts until they fork over the "registration" fee, which in MacDefender's case ranges between $60 and $80.

The criminals monetize their work by collecting these fees. And it's a profitable trade, at least where Windows scareware's concerned. Back in 2008, SecureWorks, now owned by Dell, said that some bad guys were making as much as $5 million a year shilling scareware.

So MacDefender isn't hacking my Mac? No. Although scareware targeting Windows has been known to silently plant itself on PCs after other malware first exploits a security vulnerability in the OS or other software, MacDefender doesn't.

That's a possible future move, of course, assuming attackers spend the time digging up an unpatched vulnerability in, say, Mac OS X or a browser like Safari or Firefox, and then write an exploit.

So how do Macs get infected with things like MacDefender? Easy, they dupe users into doing the job for them.

The group behind MacDefender entices victims to malicious sites, where a Web page that looks like the Mac Finder appears, runs a phony virus scan, then claims that the machine is infected with dozens of Trojans. When the unsuspecting user clicks the "OK" button, MacDefender downloads to the Mac.

Such social engineering-style attacks are commonplace on Windows, but have been rare on Macs. Looks like that party is over.

Okay, so I fell for the ruse. What happens next? Once it's downloaded, MacDefender automatically pops up an install screen on Macs where Safari is running.

If you used another browser to download the scareware -- Firefox or Chrome, for instance -- the criminals rely on you to find the just-obtained installation package in the browser's download destination and click on it.

Next you'll see a typical Mac installation process. (In earlier versions you had to enter your administrator password, but that requirement's been eliminated in the most recent version, dubbed "MacGuard.")

Once MacDefender's fooled you into installing it, the scareware runs another scan and drops numerous alerts on the screen, all part of the scam to make you think your Mac is infected.

To remove the "infections," you have to pay up by entering your credit card information.

I'm not completely stupid ... I just won't pay up. What happens then? MacDefender -- which also goes by names like MacSecurity, MacProtector and now, MacGuard -- duns you with those irritating pop ups, flashes an icon in the menu bar, and worst of all, opens pornographic pages in your browser every few minutes.

That last is a new twist to spur you to pay for the scareware.

"We think they're doing this because most people will assume that that means they've got a virus on their Mac, and they need to get rid of it by paying for the program," said Peter James of Mac-only security software maker Intego in an interview earlier this month.

MacDefender automatically runs each time you start your Mac, so you can't get rid of it by restarting or shutting down the machine.

So it's here to stay? Isn't there a way to get rid of it? Yes, you can scrub your Mac manually.

Earlier this week, Apple finally acknowledged the MacDefender scareware campaign by posting a support document on its site. That document spells out the removal steps you should take.

Can't the Mac remove this itself? Not yet. But Apple's promised an update to Mac OS X 10.6, aka Snow Leopard, that will.

"In the coming days, Apple dell inspiron 6400 battery will deliver a Mac OS X software update that will automatically find and remove MacDefender malware and its known variants." Apple said in the support document it published Tuesday. "The update will also help protect users by providing an explicit warning if they download this malware."

Only Snow Leopard has rudimentary antivirus capabilities, which can warn users of a small number of threats. That same feature can also quarantine already-downloaded files that it deems dangerous.

But Apple seems to be saying that it will add a cleaning tool to Snow Leopard that can scrub an already infected Mac. If so, that would be a first.

And it would mean that Apple would be following in the footsteps of Microsoft, which has offered free cleaning tools -- notably the Malicious Software Removal Tool, or MSRT -- for years. MSRT is updated at least once each month, then pushed to customers via the Windows Update service.

People running older versions of Mac OS X, including 10.5, aka Leopard and 10.4, the even older Tiger, presumably will be on their own.

How pervasive is MacDefender? No one really knows.

A back-of-the-envelope estimate by Ed Bott, a ZDNet blogger who usually writes about Windows but has dealt out a series on MacDefender, put the number of infections between 60,000 and 125,000.

While security firms that sell Mac antivirus software have not tossed out numbers like that, at least one -- Intego -- has cited Bott's estimates and concluded that "this fake antivirus has been extremely effective in tricking Mac users."

Today, Finnish antivirus company F-Secure said it had seen "a significant rise on infections with the Mac rogue Trojans," but didn't specify the raw numbers or the rate of increase in infections.

Companies like Intego, of course, have an interest in touting MacDefender's ubiquity: They sell antivirus software for the Mac.

F-Secure, in fact, launched its first Mac-specific product today.

Symantec, which has one of the world's largest network of malware sensors and "honeypot" systems -- and also sells Mac security software -- said it didn't have "much if anything, in the way of hard data/numbers" on the Mac scareware campaigns.

Bottom line: There's no solid evidence yet on how many Mac users are falling for the con.

Why the Mac? Why now? The question should be, "Why not before this?"

Scareware has hammered Windows users for years, and remains a very popular way for criminals to make money. According to Microsoft's latest security intelligence report, the company's MSRT cleaned millions of scareware-infected Windows PCs last year.

Both Intego and Microsoft Compaq nc6400 battery have reported connections between MacDefender and a gang responsible for one of the biggest Windows scareware families.

Intego has said that the group simply added MacDefender to its scam arsenal by developing the Mac-specific fake antivirus program, then seeded it to the same malicious sites that were already serving up Windows scareware, in effect getting a bigger bang for its buck.

Apple's increased sales of Macs may have triggered the move by the gang. While Windows PC sales have stalled -- and still greatly outnumber Mac sales -- Apple's sales of desktops and notebooks has outpaced PC sales for 20 consecutive quarters.

Where there's a market for malware, there's malware.

What can I do to keep MacDefender and its like off my Mac? Lots of things, actually.

For one, be wary of search results on hot news topics, since scareware scammers constantly "poison" those results to push their sites higher on the list. When MacDefender first appeared, it was spread through sites that ranked high on Google Image searches, and those resulting from searches for information on Osama Bin Laden's death.

For another, don't install anything you haven't downloaded yourself.

If you browse with Safari, head to its Preferences screen, then uncheck the box marked "Open 'safe' files after downloading" at the bottom of the General tab: That keeps Safari from automatically opening the installation screen of MacDefender.

Only type in your account password when installing software you actually want and asked to be installed. If the account password dialog pops up and you don't know why, don't enter your password.

Speaking of accounts, the newest MacGuard scam doesn't require a password when you're running under an administrator account. You might want to switch to a standard account instead, which will prompt you for a password when MacGuard tries to install. Check out this Apple support document for how to set up a standard account in Snow Leopard.

Don't pay for security software you haven't asked for. Don't enter your credit card information in any prompt to register such software.

Consider adding an antivirus program to your Mac. Sophos gives one away free, and others, including F-Secure, Intego and Symantec, sell products that will block scareware and remove it if it's infected your machine.

If I buy an imac, should I buy microsoft office for the mac or just stick with iwork?

What problems if any would I run into? Example: creating a document with microsoft word (at work or school) and then opening it with pages. Is that possible? Any other advice for a potential mac buyer. They recently upgraded their Ram and processors on the imacs so they are selling the previous version for $200 less ($1299- 20" monitor). Is it worth it to buy the newer for $1499? Thanks!

Hey,

Pages (and Keynote and stuff) can open Microsoft Office format documents, but it is not always fully compatible, so some stuff (like clip art, different fonts and such) may not be transferred. If you are working on both macs and pcs, then office might be a good option, even though Pages is probably a better program on a Mac.

As for the iMac thing, not sure which model you are referring to, but they did recently upgrade the whole iMac range to the newest processors a couple of weeks ago. The only difference is speed and memory, it depends what you are doing with your computer, but if you are a serious user then go for the upgrade, a casual user then i would recommend sticking to the cheaper one if thats best for you!

Hope that helps.

Word Document Corruption Due To Abrupt System Shutdown

While working with a Microsoft Word document, you can never be certain about its corruption. It can happen anytime. One of the most common reasons for the Word document corruption is when the system shuts down in an improper or abrupt manner, while the document was open. Due to Word document corruption, all the contents or data stored in the document gets inaccessible. To access the data, you can use a healthy backup file (if available) to restore the data. But, in an unfortunate event where the backup file is not available or it fails to restore the data, there you need to repair word file using an effective third-party file repair application.

To illustrate the above case, consider a practical situation where you are working with a document and you accidentally switch off the main switch of your computer system, due to which it gets shutdown improperly. After restarting the system, when you try to open the document, it does not open and you receive any of the following error messages:

• "????.doc cannot be Worded. The file may be read-only, or you may be trying to Word a read-only location. Or, the server on which the presentation is stored on may not be responding."

• "Unable to read file."

• "The file is not in a recognizable format."

• "Word.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created."

The occurrence of any of these error messages proves disastrous as the data stored in the Word document gets inaccessible.

Cause:

The reason why these error messages appear is because of the corruption of the Word document.

Resolution:

Word document corruption due to abrupt or sudden system shutdown can easily be dealt with a powerful word repair software that can Repair DOC file completely. The software scans and repairs the Word document effectively by employing highly advanced scanning algorithms. The application allows restoration of the repaired Word document on default or new user-specified location. It does not overwrite or alter the original settings of the document.
