New Vulnerability discovered in the iPhone

Thursday, July 30th, 2009

iphoneA vulnerability has recently been discovered in the iPhone. Apparently by sending a single character text message or a series of blank messages to an iPhone will confuse it and open it up for attack.

Many people use their iPhones and apps for many aspects of their lives so if their iPhone were to get hacked it could be detrimental. The attacker could get everything from contacts to personal and financial information.

As of right now Apple has not released an update to fix this security issue.  It is not perceived as a serious threat at this time but iPhone users who want to be safe can simply power down their iPhones for now until an update has been released to deal with the issue.

Conficker Virus silent for now

Thursday, April 2nd, 2009

conficker-wormThere was a panic recently that a virus known as the Conficker virus was set to activate on April 1, 2009.  Well today is April 2 and it looks like nothing happened.

Part of the problem that caused the panic is the fact that no one knows what the Conficker virus is going to do. You see, when most viruses are discovered they have instructions encoded into them that tell the virus what to do. The Conficker virus is not accompanied by instructions. It instead dynamically references thousands of websites looking for instructions.  This means that the master(s) of this virus can upload instructions to any one of these thousands of sites and the virus will find the instructions and obey orders.  If given the appropriate orders that virus could start stealing credit card numbers off of your computer or take over your computer and turn it into a spamming machine.

Now that I have probably terrified you with worst case scenarios, I’m going to tell you that you should not get all worked up over this threat. Here are some reasons why.

  • Most computers infected by this virus are in Asia and Europe. Security professionals predict that only about 6% of computers in the United States are infected.
  • The virus is only known to infect Windows computers. You are safe if you have a Mac or Linux/Unix machine.
  • You should be safe as long as you have anti virus software and keep it updated. AVG is a simple yet powerful antivirus solution that we recommend. They have a free version for noncommercial use, as well as affordable paid versions for commercial use. You can get AVG Anti virus by visiting avg.com.
  • Download windows updates and security patches. Microsoft regularly creates and releases security patches as necessary to deal with virus threats.

If you want to be sure that you don’t have the virus you can download the W32 Downadup Removal Tool from Symantec and it can scan and remove the virus from your computer if it is present.
