Thanks to Google, there’s a tool you can use to check any site and see if Google lists it as hosting any suspicious files or acting as a malware intermediary. Yes, I know there’s a Firefox extension and that the Google Toolbar for Firefox incorporates the tool, but what if you’re out in the field on a machine that doesn’t have the tool installed and you want to check a site? Simple. Use this URL:
“http://google.com/safebrowsing/diagnostic?site=[URL of site you want to check]” (Leave off the http://).
For example, this URL produced the report shown in the screen shot (click on the image to view it full size):
http://google.com/safebrowsing/diagnostic?site=itknowledgeexchange.techtarget.com

Try it out for yourself on your favorite sites. You might be surprised at what you find out.
(Thanks to Steve Gibson and Leo Laporte of Security Now! for presenting a reader comment that brought this to my attention.)

As if we don’t already have enough to deal with, it seems that malvertising–a technique where malicious code is placed in an online ad to either mislead the user or infect their computer—is on the rise. Microsoft recently filed five lawsuits against unnamed individuals accusing them of posting ads containing malicious and deceptive code on its MSN advertising network. And when Microsoft stands up and takes notice against a threat, you know it has some teeth.
The lawsuits Microsoft filed allege that individuals doing business as Soft Solutions, Direct Ad, “qiweroqw.com” (that’s a randomly generated name if there ever was one), ITmeter INC, and “ote2008.info” used malverstisements to either spread malicious code or deceive users into visiting websites that peddle scareware. Microsoft hopes that by filing civil suits in the U.S., the individuals responsible will be discovered and enjoined from continuing to post malvertising.
Recall that last week, as reported in The Register, an ad appeared on the New York Times web site offering a virus scan that then attempted to sell scareware to the user (“NYT scareware scam linked to click fraud botnet”).
As always, I recommend using a secure browser (Firefox with NoScript) and keeping your OS and security software up to date. Oh, yes, and a healthy serving of general caution couldn’t hurt.
Caveat araneo-fluitator! (Let the web-surfer beware!)

A client recently called about his home PC saying that there were all kinds of pop-ups telling him he was infected. Naturally, the pop-ups promised to remove the “infection” for $49.95, a typical scareware tactic. I figured this would be a simple job, probably WinAntivirus Pro or some variant of it, and I would be in and out in less than an hour. I was wrong; he had deeper problems.
When I booted his PC, I was confronted by multiple command windows all with the title “desote.exe.” I was able to get to a web page and determine that this file is related to Windows Police PRO, a WinAntivirus Pro variant. I was also able to download MalwareBytes’ Antimalware. It wouldn’t install; desote.exe popped in every time I tried to run MBAM installer. I decided to try a manual removal to get the PC to where I could run MBAM and clean things up later, so I deleted desote.exe, dbsinit.exe and a couple other related files. That was a mistake; Windows lost its ability to run .exe files.
I knew I’d probably have to hack it, so I fell back on an old trick: When .exe files won’t run, change the extension to .com. This worked. I was able to install MBAM, run it, and get the system cleaned up. Turns out that the malware changes the registry key HKCR\exefile\shell\open\command from the (Default) entry of ["%1" %*] to [c:\windows\desote.exe "%1" %*]; since desote.exe was missing, Windows didn’t know what shell to run .exe files with. Besides that, MBAM found rootkit components that would have been difficult to remove manually.
Hacker skills are valuable for us white hats.

I received some good feedback on my “14 Golden Rules of Computer Security” list, in particular, this comment from Michael: “…you encourage people to go through all the effort of running Virtual Machines to protect themselves from malware, but you don’t actually encourage them to run Anti-Virus software. Which basically, unfortunately, means you’re violating rule #1 and much more likely to run into rule #12.” This lead to a review of past articles I’ve posted on the subject and my finding that though I’ve covered all of the bases, my writing is a bit fragmented. So, you can go back to “Nine Steps to System Security – 2008", “The Lazy Man’s Way to System Security”, and “14 Golden Rules of Computer Security” and put them all together for a complete PC security package, but that’s a lot for the average user to digest.
As of today, I’m embarking on a major pre-release revision of the eBook, 14 Golden Rules of Computer Security to make sure all of the bases are covered in a logical combination and sequence. In essence, the book will begin with the concept of a security baseline—the bare security essentials—for a normal home PC setup and will branch from there.
What’s a good PC security baseline? In “The Lazy Man’s Way to System Security,” I proposed these four bare security essentials: “…a NAT router; a good antivirus program; a good anti-malware program; and, a good software firewall.” That was good enough at the time, but these days antivirus, antimalware and a software firewall are usually combined into a single suite. I choose to align with Windows Secrets’ Security Baseline page: “…a hardware firewall that’s built into your [NAT] router, security software that guards against all types of malware threats, a software-update service to ensure that your applications are patched against the latest exploits, and a secure browser.”
There are many possibilities for implementing those four basic items and that will be well covered in the book.

It’s just not in fashion anymore; phishing attacks are ‘way down, falling out of favor with cybercriminals who now prefer malicious websites and password-stealing Trojan horse programs.
IBM’s security research and development division, X-Force, recently issued a report that found throughout 2008 , phishing volume was around 0.5 percent of overall spam volume. But in the first half of 2009, the volume of phishing attacks fell to around 0.1 percent of spam volume. Not only did the volume of phishing attacks drop, but the targets also changed: in 2008, 90 percent of all phishing attacks targeted the financial industry; in the first half of 2009, that percentage had dropped to 66 percent.
That’s the good news. The bad news is that, according to the report, the number of malicious Web links is up 508 percent in the first half of 2009 and many of these links appear on otherwise trusted sites such as search engines. X-Force Director Kris Lamb says, “There is no such thing as safe browsing today and it is no longer the case that only the red light district sites are responsible for malware. We’ve reached a tipping point where every Web site should be viewed as suspicious and every user is at risk."

As always, let the surfer beware.

Rogueware? The names just keep coming. It’s another name for Scareware, that stuff designed to cause shock, anxiety, or the perception of a threat, generally directed at an unsuspecting user. The end result is to steal money from PC users by luring them into paying to remove nonexistent threats. Disturbing statistics point out why this stuff won’t go away:
- Cybercriminals are earning approximately $34 million per month through rogueware attacks
- Approximately 35 million computers are newly infected with rogueware each month
- Rogueware is being distributed through Facebook, MySpace, Twitter, Digg and targeted BlackHat SEO attacks
- Research confirms that majority of cybercriminals operate from Eastern Europe
PandaLabs, Panda Security’s malware analysis and detection laboratory, announced yesterday that they’ve made a multi-year study available that examines the proliferation of rogueware into the overall cybercriminal economy. The report, “The Business of Rogueware,” by PandaLabs researchers, Luis Corrons and Sean-Paul Correll, reviews the various forms of rogueware that have been created, and displays how this new class of malware has become an instrumental player in the overall cybercriminal economy. The study also provides in depth analysis on the increasingly sophisticated social engineering techniques used by cybercriminals to distribute rogueware via Facebook, MySpace, Twitter and Google.
It’s very clear the whole landscape has changed from a vandal model to a profit model. It used to be that the cyber-vandals trashed your hard drive and wrecked your website; now, cyber-criminals use tactics to steal your identity and extort money from you. The damage is no less costly, it has just increased in both the intensity of emotional pain and amount of financial loss. The difference is that cyber-vandals didn’t have a payday—cyber-criminals do.
And people ask me why I’m adamant about cyber-security…

Michael Jackson malware? Farrah Fawcett phishing attempts? Billy Mays spam? Ed McMahon notifies you—from the other side of the grave–that you’ve just won the million-dollar Publisher’s Clearinghouse (but you have to send him some money, first)? Yes, expect it. US-CERT is monitoring reports of an increased number of spam campaigns, phishing attacks, and malicious code targeting the recent deaths. Here’s a typical example:
To: <redacted>
Subject: Confidential===Michael Jackson

Confidential
Vital informations after the death of Michael Jackson’s I really need some one trusted & secrective to speak with with informations i have in my possession before its too late Kindly reply me and i will immediately respond back,Its for just secret between both of us.
Notice the blatant misspellings, lack of punctuation and obvious grammatical mistakes from someone who is clearly not a native English-speaking person. If you get this email, delete it immediately. Same with anything related to any of the other celebrities’ deaths.
They’re all from scammers (criminals) either trying to steal your money, your identity or both.

Enter “screensavers” into any major search engine and there’s better than a fifty percent chance that any result you click on will land you on a malicious website. According to McAfee’s recently released report “The Web’s Most Dangerous Search Terms,“ that search term carries a maximum risk of 59.1 percent. Furthermore, lyrics and anything that includes the word “free” have a high risk of exposing users to malicious or fraudulent web sites. Health-related search terms have the lowest risk profile. Check out The Web’s most dangerous keywords to search for on ZDNet.com.
One of the biggest problems is that the bad guys, using Black Hat SEO techniques, grab onto the trending search terms of the moment and use their popularity to get links to compromised sites placed high in the search engine rankings. This, coupled with the fact that 77% of Websites carrying malicious code are legitimate sites, make for an increasingly dangerous environment for the casual surfer.
This is yet another reason to continue to beat my drum: If you use IE, disable scripting and ActiveX (IE8 has increased security, so consider upgrading). Better yet, switch to Firefox and use the NoScript plugin. Tell the users who trust you to do the same, will you? And make sure they have the latest security patches on their systems. Most people are trusting souls; on the web, they shouldn’t be. Let’s instill the “trust no one” (except for us white hats, of course) mentality into everyone we can.

I’m going to take a lot of heat for this post. Maybe. Unless I’m right (which I usually am). So, let me just get it out of the way: The state of security on the Internet today is NOT YOUR FAULT. Neither is it the fault of the clueless surfers who click on any and every link in their email and say “yes” to every popup on their screen. It’s not the fault of those who love to install the “little bitty kitty” screensavers that are loaded with adware and the ones who use the “fun web products” emoticons and stationery with similar bent. No, it’s not your fault.
It’s M….no, it’s U….no, it’s…hell, it’s the software developers who don’t have a clue on how to write a secure application. The end user—be she a geek or a regular consumer user—has no way of knowing that there are security holes on the software she uses. And she shouldn’t have to be concerned about it, now, should she? NO.
The more I have to deal with the malicious–and sometimes just crappy–stuff that people manage to get on their systems, the more I want to grab the programmers, web app developers, and insecure software purveyors by the throat. Conspiracy theorists speculate that since the anti-malware software industry is a multi-billion dollar cash cow, we don’t have a chance of ever seeing truly secure software. I don’t think that’s true. There’s enough crap out there to keep the anti-malware industry busy for a long time.
But it does make one wonder, doesn’t it?
