VPN – The Fastest Way to Get Hacked!

Posted by nik on April 24, 2008

This is a guest post authored by Monte Russel.

VPN (Virtual Personal Network) is very convent way to connect while you are away from your normal network. This is a network protocol that builds a private path or tunnel from your computer to the network you want to connect to. A lot of companies utilize this protocol for their employees to connect to the business network while traveling or working from home.

As with all network devices, once you leave the safety of the local area network (LAN) and connect to the Wide Area Network (WAN) or World Wide Web (WWW) your protocol is subject to attack by the unscrupulous that inhabit the WWW. Hackers, thieves, and criminals have tools to defeat a normal VPN’s security. To be safest, you or your company should invest in a commercial VPN package.

A commercial package will have encryption as part of the VPN. With the encryption you will have two keys, a private key and a public key. Only you know the password to the private key and only the company knows the public key. For a hacker to gain access to the encrypted data you are sending back and forth on the VPN they have to crack both keys the public and the private key. By the time they have cracked the key you will have ended your session and move away from their locality. That is unless you establish your VPN and leave it on for a long period of time, a very long time. At this time the best programs that can recover passwords take anywhere from two days to a week to get the password to a 16 bit encrypted key. Newer programs use 58 bit or 64 bit encryption keys.

So now you want to know if your VPN is encrypted? Well one way to know is ask your IT department. Another is when you installed your VPN did you have a ‘Certificate’ that you had to install and then create a password? If you have a certificate and had to create a password then type random characters on the key board to create the key you have encryption.

If you don’t have encryption I suggest you contact your IT Director or Manager and find out why your VPN is open to anyone who wants to connect while you are connected. An open VPN is an invitation not only to the data you are transferring back and forth but to the sending and receiving computers. It is like an open door on a hot summer day, any thing can and will come in to the house.

Lol Monte… I just went to your website and I have to say it’s so full of it! But I digress.

Anyways Gbridge uses AES 128bits encryption and is authenticated with SHA1 HMAC by session keys that are only known to my computer and my peer’s computer…

http://www.gbridge.com/

Perhaps that proves that Gbridge was invented in the future and sent back in time by Skynet or perhaps has an alien origin? At least according to you anyways. Your article is published in 2008 but you’ve probably been living under a stone for the last decade?

If that’s the case then it totally explains why this article and your website is like abysmally outdated.

Oh by the way Dolores, I bet you probably know much more about computers than this guy who claims that VPN is the fastest way to get hacked. LOL.

And to clarify for the n00bs, the fastest way to get hacked is a) Use Windows or b) Use the Internet. And VPN doesn’t even come anywhere close.

Monte please… Please double check your facts before you write another stupid article, or better yet stop altogether. Because unlike me, not everyone on the Internet can tell immediately that you’re so full of it.

Have a nice day!

I have a personal vpn, and have recently secured my wireless internet that I suspect my neighbor was using before. There is a computer logged on to my network, when I attempt to explore the IP, it asks for a user name and password. Mine don’t work. Can a person hack into my neighbors computer and then access my wifi assuming they have already hacked my VPN? This foreign computer on my network has me concerned. I have seen it on my computer before and chalked it up to the neighbor but now I wonder how it is accessed when the wireless is secure.

Hi Dave,

The url in the article http://www.Diy-Computer-Repair.com/vpn.html is wrong, the published web page is http://www.Diy-Computer-Repair.com/info-vpn.html

I had to change the name of the web page.

Actually the fastest way to get hacked is to leave your computer unsupervised. 90% of hacks done on computers are done when the hacker has physical access to the machine, or is able to phish information out of the computer owner.

When a military base in washington state had the identities of 30 of its employees stolen…it was done by someone who physically stole a computer from the base. Talk about bad network security.
