downloading Adobe Flash Player annoyances

Every so often, Adobe releases updates to fix security holes after researchers and other security specialists find holes and exploits in their Flash Player. These updates are usually critical and require you to update your version of Flash Player on your computers asap.

The problem is that installing and updating Flash, in my opinion is a pain in the ass. This is one of my bigger annoyances since its very widespread and affects pretty much anyone.

The Adobe Way of updating these browsers:

  • Mozilla Firefox: Updating flash is a bit of an annoyance for Firefox users. I don’t want to use Adobe’s Download Manager. I’d prefer to keep extra extensions off my Firefox profile.
  • Internet Explorer: Updating flash for IE isn’t super easy/friendly as well, it involves downloading an ActiveX plugin containing Adobe’s Download Manager.
  • Google Chrome: Probably the easiest browser to update since Google actually pushes updates to your computer. When a Flash update is released, your browser should automatically update Flash after the next restart.

I think Adobe’s way takes too long and is a headache. Too many clicks, too much user interaction needed.

My solution is to download the local installers directly and just run them. Its a lot faster, simpler, and easier. Whenever I’m working on client’s computers, I take this route.
Unfortunately, finding the link for the direct downloads can be quite hard sometimes, also taking an excessive amount of click and searching. I finally decided to use my favourite URl shortener service Bit.ly to make my life a lot easier.

If you go to http://bit.ly/dlflash it’ll take you to the page that has the manual download links for Internet Explorer and Firefox/Opera/Safari…etc. Feel free to use this link. It’ll work as long as Adobe doesn’t change and/or remove the links..

Hopefully this’ll make updating flash easier and faster for you.

Oh, and if you’re wondering if your Flash Player does need updating, visit http://www.mozilla.com/plugincheck and it’ll tell you if it needs updating, as well as other plug-ins installed on your browser.

How to prevent Wi-Fi Piggybacking?

In any form of Internet communications, there is always a possibility for your information or data to be intercepted by people (or machines) you’re not suspecting. This article will provide you with some basic information about wireless networks (Wi-Fi), discuss some possible ways your data can be intercepted over Wi-Fi and simple methods of preventing these risks on Wi-Fi.

Some background info about Wi-Fi

Wireless networks began popping up in homes about 10 years or so. They have vastly changed the way we work as it allows portability and convenience around the house and the workplace. It prevents us from having to fully wire our houses, whether old or new, vastly reducing labour and integration costs. Service providers are now implementing wireless into their modems and routers. Universities offer campus-wide wireless in their campuses, and there are millions of hot-spots all over the world in libraries and coffee shops.

Beyond the scope of this article are the types of wireless network protocols. Some of the more tech-savvy would know this as 802.11a/b/g/n type wireless standards. Although it is important to know that there are differences between them, for the most part, it doesn’t change how privacy can affect you by using the different protocols. We can assume however, that the most predominant protocol being used, at the time of this blog post, is 802.11g which was standardized in 2003.

What are the dangers

If your Wi-Fi is unencrypted, then this it is important that you pay attention to this!

Like any other form of radio communications, Wi-Fi travels over the air and there is no way to control who else can listen to the basic signal. Therefore it has no way to prevent piggybacking or snooping of its basic unencrypted signal, which is the term used when an unauthorized user is able to listen in on your conversation.

For an example, think of your local FM radio station. FM signals do not care who is tuning into its channel, whoever does, will inherently be able to listen to the signal it is broadcasting as long as it’s within range. Since FM radio is usually designated as a public system intended to reach the general population, it is not a great example to demonstrate “Piggybacking” or snooping. However, if you were to designate a FM radio station as private where the intended purpose is for only you and a select number of authorized people were supposed to be able to tune into a specific channel, the moment an unauthorized person tunes into the station, he is then to piggybacking on your station and listen to everything that is to be heard over the specific FM radio channel.

Thankfully, unlike FM radio stations, Wi-Fi does not operate at extreme power levels, so the area of penetration that your computer and wireless router operate at is very low. Although this does lowers the amount of area that people can intercept your data, it does not eliminate the risk.

The ability to intercept Wi-Fi communications is very easy and nowadays, can be done even be done from a netbook or a simple kit. The software can be easily downloaded online and run by the click of a button. Its soo easy that you don’t need to know a lot about computers in order to intercept the data. These softwares are capable of handing the decryption of WEP, which, unfortunately is still used widely today on uninformed users.

Some of you may be asking, “Why does it matter/I don’t care? I have nothing to hide!”

If someone were to capture your entire Internet conversation, they would probably be able to access your passwords to your favourite websites (Facebook, Youtube, etc), your email, your online banking information, and also reconstruct what you’re doing online on your computer. They could then resell or use the information to impersonate you or steal your identity. Although this may seem a bit far fetched, why give them easy access to all this interesting data when we have the technologies to prevent most of it?

How to fix the dangers

In order to prevent “Piggybacking” a number of methods were produced by various organizations. If you simply Google or Wikipedia “Wireless Security”, you will discover many different methods of securing your wireless network.

The act of securing your network prevents Piggybacking by adding level of encryption on all the information travelling on your configured wireless network. If we look back at the FM radio example again, the unauthorized user, tuning into your designated channel or radio station, would now only hear garbled noise and have no clue how to read it.

For the basic home user/consumer, I recommend using the currently most secure
WPA2-PSK with AES encryption. If your router or computers are unable to acheive this level of encryption, I would then recommend downgrading to WPA-PSK with TKIP encryption.

Simply pick a key that is at least 10 characters long and make sure it uses a variety of different characters including special characters.

Save the key securely and only give it to people you want to have access to your network.

I would not recommend hiding your SSID or implementing a MAC address filter as it is essentially useless and makes configuration a bigger administrative pain for you and your users.

Taking these simple steps into action could prevent you from becoming a victim of data piggybacking and preventing data snoopers from accessing your personal life.

Lastly, stay on top of technology. Check for firmware updates and re-evaluate you hardware every few years to see if there are newer wireless security standards to re-enforce your network security. Something that maybe secure today, may not be secure tomorrow.

What to do if you’re on a Wireless Hotspot?

Many of you may ask…what can you do if you’re at Starbucks or at University where you need internet access via Wi-Fi and they only offer a free unencrypted version?

There’s not a whole lot you can do. Unless you’re accessing online services via a specified encryption method (encrypted browsing session, VPN), you could be susceptible to Piggybacking. Generally speaking, with wireless hotspots, there are usually tons of users. A piggybacking snooper, looking for your information would have a bit more trouble sifting through all the information he’s capturing. But don’t feel to safe.

Make sure you’re accessing your email with an encrypted protocol. Popular free email providers such as Gmail defaults to this and I believe Microsoft’s hotmail is slowly following suit. If you have a different provider, visit or call your local IT administrator to see if they can give you some further information. Lastly, try and prevent doing online banking or other personal things you wouldn’t want anyone else seeing while you’re on a hotspot.

For the average user, simple steps in securing your Wi-Fi and being more aware of the dangers of using a unencrypted wireless network should hopefully prevent you from having your data snooped unexpectedly.

Enjoy a more safe and secure web browsing life.
