  • Hundreds of thousands may lose Internet in July

    Published April 20, 2012 – Associated Press

    For computer users, a few mouse clicks could mean the difference between staying online and losing Internet connections this summer.

    Unknown to most of them, their problem began when international hackers ran an online advertising scam to take control of infected computers around the world. In a highly unusual response, the FBI set up a safety net months ago using government computers to prevent Internet disruptions for those infected users. But that system is to be shut down.

    The FBI is encouraging users to visit a website run by its security partner, http://www.dcwg.org , that will inform them whether they’re infected and explain how to fix the problem. (Click “Detect” in the upper-left corner.)

    After July 9, infected users won’t be able to connect to the Internet.

    Most victims don’t even know their computers have been infected, although the malicious software probably has slowed their web surfing and disabled their antivirus software, making their machines more vulnerable to other problems.

    Last November, the FBI and other authorities were preparing to take down a hacker ring that had been running an Internet ad scam on a massive network of infected computers.

    “We started to realize that we might have a little bit of a problem on our hands because … if we just pulled the plug on their criminal infrastructure and threw everybody in jail, the victims of this were going to be without Internet service,” said Tom Grasso, an FBI supervisory special agent. “The average user would open up Internet Explorer and get ‘page not found’ and think the Internet is broken.”

    On the night of the arrests, the agency brought in Paul Vixie, chairman and founder of Internet Systems Consortium, to install two Internet servers to take the place of the truckload of impounded rogue servers that infected computers were using. Federal officials planned to keep their servers online until March, giving everyone opportunity to clean their computers. But it wasn’t enough time. A federal judge in New York extended the deadline until July.

    Now, said Grasso, “the full court press is on to get people to address this problem.” And it’s up to computer users to check their PCs.

    This is what happened:

    Hackers infected a network of probably more than 570,000 computers worldwide. They took advantage of vulnerabilities in the Microsoft Windows operating system to install malicious software on the victim computers. This turned off antivirus updates and changed the way the computers reconcile website addresses behind the scenes on the Internet’s domain name system.

    The DNS system is a network of servers that translates a web address — such as http://www.ap.org — into the numerical addresses that computers use. Victim computers were reprogrammed to use rogue DNS servers owned by the attackers. This allowed the attackers to redirect computers to fraudulent versions of any website.

    The hackers earned profits from advertisements that appeared on websites that victims were tricked into visiting. The scam netted the hackers at least $14 million, according to the FBI. It also made thousands of computers reliant on the rogue servers for their Internet browsing.

    When the FBI and others arrested six Estonians last November, the agency replaced the rogue servers with Vixie’s clean ones. Installing and running the two substitute servers for eight months is costing the federal government about $87,000.

    The number of victims is hard to pinpoint, but the FBI believes that on the day of the arrests, at least 568,000 unique Internet addresses were using the rogue servers. Five months later, FBI estimates that the number is down to at least 360,000. The U.S. has the most, about 85,000, federal authorities said. Other countries with more than 20,000 each include Italy, India, England and Germany. Smaller numbers are online in Spain, France, Canada, China and Mexico.

    Vixie said most of the victims are probably individual home users, rather than corporations that have technology staffs who routinely check the computers.

    FBI officials said they organized an unusual system to avoid any appearance of government intrusion into the Internet or private computers. And while this is the first time the FBI used it, it won’t be the last.

    “This is the future of what we will be doing,” said Eric Strom, a unit chief in the FBI’s Cyber Division. “Until there is a change in legal system, both inside and outside the United States, to get up to speed with the cyber problem, we will have to go down these paths, trail-blazing if you will, on these types of investigations.”

    Now, he said, every time the agency gets near the end of a cyber case, “we get to the point where we say, how are we going to do this, how are we going to clean the system” without creating a bigger mess than before.

    Knowing that a lot of people don’t follow links to news articles in a forum, I decided to paste the article here.

  • Interesting.  Thanks for sharing

  • thx…  we  checked ours yesterday…scary!!!…

  • it’s funny that this sounds like a scam, but appears to be real. I was expecting for a pop-up asking for my credit card details so they could fix my issue.

  • ha ha,  me  too..

    .dh  sent himself an email about it  and i saw and  thought it  was  spam….

    we are  clear…

  • Thanks Warren, I also got an email from Comcast in the beginning of April saying that I needed to check my computers (one is still not recovered, is not working yet), that next time, they were not going to send a notice, I just was going to loose Internet connection.

  • A shortened version of the article appeared in our local paper’s Technology section (Dallas Morning News) and that started me looking online where I found the article above on the AP feed.

    Every indication so far is that it is legitimate, so just to be safe, I’d check it out.

    @trudy @annfurnivall @richardmclaughlin @hildaalanisgonzalez

  • @warrenveach Thanks for the heads up. I’m assuming that protected computers would be ok (mine are protected by Norton). Does this apply to smartphones as well I wonder?

  • @warrenveach  Thanks for posting this.  I just did the automatic and manual checks on my computer and it check out fine, but I hope everyone else is okay!

  • My computers were clean from the test, thank goodness.  Good Info. 

    Just FYI:  I use PCtools anti-virus/andi-spyware and PCtools Registry cleaner.

  • thanks, Warren, great info @warrenveach

  • The same notice appeared in the Tampa Bay Times. I decided to double check and went to the FBI web site. I used the link on their site to test my DNS lookup and got the “green” message.

  • I got the green message too!! woohoo!! @warrenveach @marketinggeek

  • So if it’s Microsoft Internet Explorer, then it should effect MACs Safari or Firefox.  At least I think that is the case.  Also I’ve found in the past that the scammers usually do this to the minus 1 or minus 2 versions of the software so perhaps if you’re using IE9 you not have an issue.  Just a thought.  @warrenveach

    I’m not sure of the cope of the threat, but here is a link to the story on the FBI website: http://www.fbi.gov/news/stories/2011/november/malware_110911/malware_110911

    Here’s another link on the FBI website to check your computer: https://forms.fbi.gov/check-to-see-if-your-computer-is-using-rogue-DNS

    @kc_kreative

    The FBI says that even NASA’s computers were affected, and “In some cases, the malware had the additional effect of preventing users’ anti-virus software and operating systems from updating, thereby exposing infected machines to even more malicious software.”

    I guess I’d rather be safe than sorry…

  • I got the green light. Thanks  @warrenveach . I am glad to know we can post this kind of info here in SME Clubs. If i were to have gotten this on Facebook I would have ignored it. 

  • @warrenveach Thanks, I got the green light, but my computer at work is only 4 months old…..I’ll have to check the computer at home.

  • @jasonwiser @trudyd1474

    It’s too bad these hackers can’t use their talents for improving the web instead of trying to tear it down.

  • July 9 is upon us, so I thought I’d throw this post back into the rotation.

    The FBI is encouraging users to visit a website run by its security partner, http://www.dcwg.org , that will inform them whether they’re infected and explain how to fix the problem. (Click “Detect” in the upper-left corner.) 

    After July 9, infected users won’t be able to connect to the Internet.

    Good luck!

  • my company is pretty big in the security domain and we are advertising this pretty heavily in the office.

  • How can you detect if your computer has been violated and infected with DNS Changer?

    An industry wide team has developed easy “are you infected” web sites.  They are a quick way to determine if you are infected with DNS Changer. Each site is designed for any normal computer user to browse to a link, follow the instructions, and see if they might be infected. Each site has instructions in their local languages on the next steps to clean up possible infections.

    For example, the http://www.dns-ok.us/ will state if you are or are not infected (see below).

    • No Software is Downloaded! The tools do not need to to load any software on your computer to perform the check.
    • No changes are performed on your computer! Nothing is changed on your computer when you use sites like http://www.dns-ok.us/.
    • No scanning!  The “are you infected with DNS Changer” tool does not need to scan your computer.

    If you think your computer is infected with DNS Changer or any other malware, please refer to the security guides from your operating system or the self -help references from our fix page (http://www.dcwg.org/fix).
