Private internet browsing mode vulnerabilities

Internet Explorer 8, Firefox +3.5 and Safari have an internet browsing “privacy mode”, using it to surf the Internet it is meant not to leave an internet cache, history cookies or anything else behind that could jeopardise your internet surfing privacy, but there are two things that still give away what sites you have visited.

  • Cached DNS Entries: In order to be able to surf the internet you will need use a DNS server to resolve the URLs and this will be cached locally into your machine for a while to speed up your internet surfing, this entries also get cached in private mode browsing.

You can see this yourself opening up the command prompt inWindows, type or cmd.exe at the search box to get to the Windows command prompt box.

Now type:
ipconfig /displaydns

Windows cmd.exe command line prompt
Windows cmd.exe command line prompt

You will see the full list of cached DNS entries, open up a new private browsing session, re-run the command again and see how the sites you just visited got added. Anyone with access to your computer, such as a noisy College systems administrator or your boss at work can see this too.

To clean up the cache just type in:
ipconfig /flushdns

  • Flash Cookies: Even in privacy mode evil flash cookies will get stored into the %appdata%\Macromedia\Flash Player\#SharedObjectsdirectory, and they can reveal what sites gave them to you, and what day and at what time you visited them, you can delete these flash cookies manually.

Review: Hide My Ass VPN provider for anonymous internet surfing

Some of you may know Hide My Ass for their free cgi proxy but they also run a premium VPN for anonymous surfing, their VPN is much better than a cgi proxy because it protects every single application and connection going in and out from your computer to the wild wild web.

Hide My Ass VPN encrypts your internet traffic and hides your real computer IP from hackers and stalkers as well as repressive regimes. They have SMTP on port 25 blocked because of abuse by spammers but you can still use webmail and the sender IP will be replaced by one of Hide My Ass VPN servers, you can also request to whitelist your SMTP emailing support.

A VPN for anonymous internet surfing will also get around internet censorship filters implemented by some countries ISPs, like the one they have in China and Australia. Hide My Ass provides PPTP as well as OpenVPN for the same price, I have only used the more secure OpenVPN and this review is based on that.

Hide My Ass VPN Advantages

There is a wide range of servers all over the World, at the time of writing you have a dozen servers in the US, four servers in the UK, three servers in Canada, and single servers in Sweden, Holland, Germany(x2), Estonia and Russia. Hide My Ass VPN service has been adding new servers all the time since I signed up with them 6 months ago.

I have found some Hide My Ass US VPNs IP has been blocked by Hulu and I easily got around this by simply choosing a different US VPN location, I never found myself in a situation where every single US server was blocked. I have also used the Canadian servers to watch online TV at and (only for Canadian residents), as well as listening to radio online, also limited to US and Canada residents only, I never experienced any problem watching US&Canadian TV from abroad using a Hide My Ass VPN located in North America.

The speed I usually get on Hide My Ass VPN servers is around 4MB download and my ISP provides me with 6MB ADSL downloads, occasionally you will find HMA VPN servers with 1MB speeds changing location will solve this.

I am normally able to watch free movies online at , and with just 1MB of bandwidth. I find Hide My Ass speed download speeds more than acceptable for my requirements.

Assuming Hide My Ass VPN FAQ is honest, they say that their VPN logs are kept for one week, this is a sensible length of time, enough to catch abusers and not extremely privacy invasive. Those logs, according to them, do not contain what sites you visit, they only contain what user had certain IP on what date from what time to what time.

Hide My Ass VPN Disadvantages

The worst part of Hide My Ass VPN client is that when you get disconnected from the network for whatever reason you will be surfing with your real IP and the VPN client makes no attempt whatsoever to warn you, instead it tries to reconnect, there is a good chance your real IP will be exposed during that time.

If you want to use Hide My Ass VPN on a BSD or Solaris system you are out of luck because it only works on Windows, MAC and Linux and the client needs to be installed.

Hide My Ass VPN Review conclusion

Hide my Ass is great to watch US and Canadian TV online, the reliability and server speed is more than acceptable to do this, as well as the wide range of locations they offer. Support always replies to email and they are quick and helpful, forget about their forum and IRC channel, if you have a problem email Hide My Ass instead! Their forum is not to be used for support.

Hide My Ass only needs to polish their VPN client about not warning you when the VPN is disconnected, and I will then increase my satisfaction rating at %99, there is something more important than speed in a VPN, their capability of being able to cover your real IP (or your ass) and if they can’t do that, then they can’t do the basics.
