What is Shodan?

EDITOR NOTE: This is Jonny’s 75th post on Technology Bloggers! Jonny was a complete newbie to blogging when he wrote his first post (about prosthetic limbs) but he is now somewhat of an expert – although he probably wouldn’t agree! – note by Christopher

Recently a couple of articles have appeared on large US websites about a type of search engine called Shodan. This search engine has been about for about 3 years, but it is different from Google and its cohorts in many ways. I looked at it and could not understand it at all, so what is it then and why is it causing such concern?

I have seen Shodan described as “The scariest search engine on the Internet”. This CNN money article explains that Shodan navigates the Internet’s back channels. It’s a kind of “dark” Google, looking for the servers, webcams, printers, routers and all the other stuff that is connected to and makes up the Internet.

What interest could there be in such capability? Well a lot apparently. The system allows an individual to find security cameras, cooling systems and all types of home control systems that we have connected to the Internet. (See Christopher’s series about his British Gas system here).

One serious problem is that many of these systems have little or no security because they are not perceived as threatened. Shodan searchers have however found control systems for a water park, a gas station, a hotel wine cooler and a crematorium. Cybersecurity researchers have even located command and control systems for nuclear power plants and a particle-accelerating cyclotron by using Shodan.

Hacking apart it turns out that the world is full of systems that are attached via router to the office computer and web server, and on to the outside world. Access for anyone who can find them and might like to turn of the refrigeration at the local ice rink, shut down a city’s traffic lights or just turn off a hydroelectric plant.

The Shodan system was designed to help police forces and others who might have legitimate need for such a tool, but what when it gets into the wrong hands. Security is non existent, just get your free account and do a few searches and see what you find.

See this Tech News World article for a further look at the ethical and practical issues that such a freely available product might bring

Regular readers will be aware of my interest in these types of problems through my work at the Bassetti Foundation for Responsible Innovation. I am not sure how the development and marketing of such a tool could be seen as responsible behaviour, but as I have been told on many occasions during interviews there are plenty of other ways of finding out such things. These types of systems are gathering already available information to make it usable, nothing more, so not doing anything wrong.

Do you agree?

Stop using Internet Explorer

This post was going to be entitled “Why you should stop using Internet Explorer” however I didn’t think that was a strong enough title, so I changed it to the direct instruction you see above this text: Stop using Internet Explorer.

You have a choice. You can use Google, Bing, Yahoo! or Ask. You can buy Windows, Mac OS, Chrome OS or Ubuntu. You can go with Apple, Samsung, Sony or RIM.

Although Google dominate the search market, there are still many other search engines out there. Microsoft dominate the computer market, but you can still choose from a [reasonable] selection of other, popular operating systems. You could argue that Samsung now dominate the global smartphone market, but there are still many other companies you can go to to get a smartphone.

You also have a choice as to what browser you use. The internet is arguably now the main function for any computer, so surely you should devote some time then to choosing which browser is right for you?

If you have tried more than three different browsers before, for a considerable length of time and have after weighing up all the pros and cons of each, have chosen your favourite, well done you. If you haven’t, read on.

If you are using Microsoft Internet Explorer (IE), stop. Okay, well you can finish reading the article, but then stop using it. A simple instruction, which could do wonders for your internet experience.

Reasons To Not Use IE

There are many reasons not to use IE. Here is a list of what I think are the strongest arguments against the heavy, slow and outdated browser.

Lack of Security

IE seems to constantly be in the news for its security issues. Much of the malware out there on the internet is only made possible by bugs and holes in Internet Explorer! Need proof? Check out this section of IE’s Wikipedia page.

Speed!

In recent years Microsoft have been really working on making Internet Explorer faster, and IE 9 is much faster than IE 6 or 7 were; granted. That said, it is still much slower than the competition. For example, loading Technology Bloggers from cold (hard refresh) in Firefox, Chrome and Safari took 3 seconds, Opera took 4, while Internet Explorer took 7 seconds.

Lack of Features

Without a doubt, for features, add-ons and extensions, Firefox and Chrome are miles out in front. Safari and Opera also have a reasonable number of things you can add to your browser to customise/improve it, but Internet Explorer has only really started to embrace such features since IE 8. Apart from toolbars, Flash, Adobe Reader etc. IE 6 didn’t really do add-ons.

Inconsistency

Social buttons badly rendered by IE

How IE rendered the same code (our social buttons) on three separate page loads – neither is correct.

Take a look at the three images to the right.

Each of the images is a different variation of the social buttons on our sidebar that IE rendered. The screen size remained the same, and the loads were seconds apart.

IE managed to render three completely different versions of the same code. How does that work?

In the first image it didn’t even attempt to load the social buttons before declaring it was finished. It took a better shot in the second image, whilst in the third image it didn’t bother loading Twitter and threw Google+ to the bottom. Why?

Upon loading the blog in Firefox, Chrome, Safari and Opera, I saw the exact same result. Each browser displayed them as they are meant to be displayed, every time – Internet Expolorer didn’t.

Lack of Compatibility with Modern Code

Code is advancing all the time, and a good browser will keep up to date with changes, and make sure it is able to interpret and display modern CSS, HTML, PHP etc.

When the blog snows at Christmas, IE doesn’t show that, IE also doesn’t like the ‘modern’ code which makes our search box work, or the code we use to add shadows to text.

Lack of Compatibility with Older Operating Systems

IE 9 doesn’t work with Windows XP, or any Mac OS or Linux system. Only Vista, 7 and 8 support IE 9. IE 10 only works with Windows 7 and Windows 8. According to StatCounter, in the last 6 months, 26.55% of all computer users used XP, whilst 7.13% used Vista and 7.46% use MacOSX – that’s 41.14% of the market that Microsoft are isolating straight away, and Windows 7 and 8 don’t even own all of the 58.86% share of the market that is left!

Advertising Campaign

Microsoft have recently undergone a quite extensive advertising campaign for IE, to try and shake off its bad reputation. They state how ‘lightning fast’ it is compared to how it used to be, which I can’t dispute. What they don’t however say is how it compares to Chrome or Opera. They also try to reassure users that it is now secure, although that is still debatable!

Which Browser to Use?

There are loads of web browsers out there, check out this handy Wikipedia comparison table to see.

Below is a map showing in 2013 so far, which internet browser is the most commonly used by country.

Top browser by country - 2013

Browser popularity by country. The colour of the country is the colour of the most used browser – see legend.

Personally I would advise using either Chrome or Firefox. If you have a relatively standard, or slow PC, then Chrome is probably best for you. It is light, simple and fast.

I still think that Firefox had more functionality than Chrome, and it is my personal favourite. If your PC is usually pretty quick and of a reasonable spec, then I would recommend Firefox.

Chrome is owned by Google – a multinational corporate giant – whilst Firefox is non-profit and open source.

Stealing Wi-Fi

Hey, come here I have something to tell you, in private. Those thieving types who live next door might be stealing your Wi-Fi you know. Not only that but Google maps drive past with their super technology cars and use your Wi-Fi, take information from your computer and all sorts (apparently). And anyone could be getting in, once on the Wi-Fi they can get into your hard disk! Well come here and let me whisper something in your ear…Wallpaper, yes from France. Tres stylish.

Wallpaper that stops Wi-Fi from passing through. You can pay your own connection, and even if you live in a shared house nobody else can get it. Ha Ha student so called friends, you can steal my cheese from the fridge but the real important stuff is mine, all mine. And it doesn’t even block out your mobile phone or the TV signal, how about that for fantastic? And it comes in a lovely snowflake design, perfect for any look, from Abba revival to minimal chic.

Block in Wi-Fi

Take a look at this link here, it’s in French I know but an online translator will help for anyone who doesn’t understand.

CNN have got onto it too, so keep it a bit quiet otherwise everyone will get it, and you will end up walking for miles through the suburbs with your mobile phone looking for someone with open Wi-Fi overspill.
