WARNING! July 9 DNS Changer Malware Alert!

The news stories are covering this all over the place, so we thought it would be good for us to get you the details as well.

Basically, before tomorrow – July 9th, 2012 – be sure to go to http://www.dns-ok.us/ to make sure you aren’t infected.  Very few computers have been infected, but it can’t hurt to check yours out – and do it before tomorrow, as the malware keeps you from going to the internet! It is a pretty busy site, so you may need to wait a bit.  To make it short – if the background turns green, you are safe.  If it turns red you will need to take a few more steps to clean up your system.

If you’re not a do-it yourselfer, there are quite a few good companies that will do this for you. http://www.dcwg.org/fix/
You can read all about it at http://www.abcactionnews.com – and if you waited too long to check out the site, you can always pick up the phone and give us a call… not that you can read this after tonight at midnight and you have been infected…
Happy computing!
 

Can I just click OK?

What if the greatest threat to your company documents, inventions, client list and financial info, was already inside your firewall?  Don’t think too long about it because it’s already true.

Yeah those wonderful co-workers in your company, especially the ones that bring donuts in on Friday, they’re also the weakest link in the chain of security that prevents your sensitive business information and secrets from being broadcast around the world.

Sound scary?

In our field of networks, computers, firewalls, antivirus, anti-malware and anti-threat, it’s well known that the most effective technique that hackers use is social engineering.

Social engineering in the hacker world tells them how to set their trap right where a normal carbon unit would step.  Even in the legitimate world of software makers like Java or Adobe Acrobat or Microsoft Internet Explorer, what we like to call crapware gets downloaded every day.  Your machine tells you that you need to update and so you agree to its all-knowledgeable directive and click through the screens until it does its thing and goes away.  Only you didn’t see the little checkbox asking if you also wanted this other program, or that you’d prefer your homepage and search engines to be changed to this site or that.

Yet just clicking OK without thinking is kinda like walking alone through New York’s Central Park at night counting Benjamins in your wallet, all the while singing “Money for Nothing” by Dire Straights.

Here’s a silly example:  If you were perusing the City Pages website, perfectly legitimate, reading about upcoming music and movies and other events, and you came across a button, and I’d like a show of hands here, that said “Don’t Click This Button”, how many of you would click that button?  Just to see what was on the other side?

In case you’re wondering, a Minneapolis underground music website actually had a button like that.  On the other side of that click was a simple page that said “You’ve been added to the list”.

So the hacker playbook says lull people into clicking on stuff they always click on or trust, or pique their curiosity, but slip a little bug to them along the way.

Almost sounds like a thrilling spy novel doesn’t it?

One piece of advice:  Be aware, don’t just click OK.

Another piece of advice: Consult a professional IT company like Computer Wrangler who can advise you and even train your staff in secure computing.

Happy computing!

 

Avoiding Viruses & Malware!

First – a simple definition of what malware and viruses are.

  • Definition:  Malware and viruses can be defined as malicious software directed at your computer. Malware is actually a portmanteau of those two words.
  • Difference between virus and malware is that viruses can spread to other computers via networking, flashdrives, etc.  Sage advice – don’t go putting your flashdrives into computers you don’t know!

Viruses:

  • Viruses can now basically be considered Modern Day Warfare.
  • Take, for example, the Iran Nuclear Facility a few weeks back – ‘Someone’ injected a virus into the system that spread through all the computers and not only shut down progress, but also set it back months.

Malware, a couple examples:

  • Spyware:  Software out there gathering all your personal information covertly. Passwords, Internet usage,
  • Scareware:  Scam Software sold to consumers via certain unethical marketing practices.

What can you do?

  1. PAID antivirus/antispyware. We highly recommend NOD32 from www.eset.com. The more popular AV programs that you hear about, or that come with your computer when you buy it, are the ones that hackers attack first.
  2. Keep your Windows or Mac updated with the latest patches. Microsoft puts out patches for its programs on the 2nd Tuesday of each month and many PCs are automatically updated – it is worth double-checking that yours is too!  Go to control panels, automatic updates and make sure yours is turned on.  Then leave your PC on overnight – you’ll see a message in the morning to tell you it’s been it has been updated.
  3. Make sure you are behind a good Firewall – and not just your internet provider’s modem.  The majority of those Firewalls have a list of sites that are ‘bad’ and protect only against those.  You need a Firewall that has SPI – Stateful Packet Inspection.  This looks at individual ‘packets’ of info on a site and inspects them daily, with current information.
  4. Practice safe searching. Don’t search on current events, news or trends.  A search term of ‘Beatrice’s Pretzel Hat’ or ‘Brooklyn Decker’ is prime target for attack. Go to reputable pages such as www.cnn.com or www.minnesota.publicradio.org to view articles.
  5. Read the URL backwards! How many of you do searches and at the results page only look at the title and the description – but not the URL?  www.cnn.com – good. www.cnn.com.cn -  .cn means China – everything to the left of .cn is anybody’s guess & not what it appears to be. DO NOT PROCEED to click on it. You can’t always trust the link at the bottom either – scroll over the link to verify. Where it is bringing you will pop up in the lower left hand corner of your window.

This is just the basics, folks, in it’s simplest form so everyone can understand.  However, just like the flu shot you get, it doesn’t mean you will not get any viruses, but it is a step in the right direction!  Just wash your hands often and hope for the best.   Now go out there and practice safe computing!
