FBI shutting down extra DNS servers, could kill the Internet for thousands?
OK, this has had lots of news organisations going crazy. Imagine it! The internet gets shutdown. Very sensational!
Take a breath, another sip of coffee/tea/whatever and read on…
Spin back to November 2011. You may or may not of heard reports the FBI had busted a large botnet network and we might have noticed a drop in spam email. When the Feds shut this network down they did something that was unexpected.
They kept some of it running.
The malware that made the botnet network what is was did most of its work by messing with DNS settings. If you are not familiar with DNS, listen in to tomorrow morning’s show or catch the recording and I will explain DNS. Hopefully I will be able to explain it in a way that makes it easy to understand.
Now the FBI has decided to shut down the last parts of the botnet which will result in around 360000 computers no longer able to access the internet.
Fortunately we have ways to detect and repair this.
CERT has a page dedicated to detecting if you have the problem and should also have links to help remove the problem if you are infected. Just go to dns-ok.gov.au to find out if you are infected.
Keep in mind that the estimated figure of 360000 is worldwide so most Australians should be OK. Better safe than sorry though, right?
Of course, if you have all your data backed up you can happily just format your hard drive, re-install your preferred programs (without the junk you don’t need) and restore your data. This spring cleaning should be done regularly anyway.
Samsung could be adding cloud services to Galaxy lineup.
The mobile technology space is possibly one of the fastest and competitive areas in the business and technology worlds and the competition is fierce between the two heavyweights Samsung and Apple. On the heels of a Samsung event announcement early next month in London we are hearing rumors that Samsung may be releasing or announcing a cloud service much like the icloud by Apple. I expect that we should see similar services like backing up devices, synchronizing email, contacts, calendars etc.
Java Exploits – Follow up
Over the last two weeks I have been letting people know about the Flashback malware and its variants that have been affecting computers including Apple Mac products.
The way this is getting in is through a security hole in Java which allows the malware to be installed on the target computer. I have been directed to a website that does a good job of telling you if your installation of Java is vulnerable or not. If you want to know if you Java installation needs to be updated go to http://isjavaexploitable.com/ to get a straight answer.
