Apache 2.4.3 now ignores DNT by default for IE10 users.
As per the new default httpd.conf file:-
<IfModule setenvif_module> BrowserMatch "MSIE 10.0;" bad_DNT </IfModule> <IfModule headers_module> RequestHeader unset DNT env=bad_DNT </IfModule>
The good news is though, that this behaviour can be disabled by simply commenting out the above lines.
I can’t believe they called it this but here’s a site of novelty:-
It is done using some automated search scripts to search for well known samples.
It’s a great idea – the scary thing is – what kind of spoils are others collecting?
Here’s another great example of how companies can evade your desire for privacy:-
The Register – Yahoo to ignore DNT
Thanks Yahoo for honouring your user’s privacy – NOT!
It’s pretty fair to say that admin.com is probably one of the most abused domains in the world.
I take my hat off to them in their attempt to combat spam.
They tool the simple eloquent solution of setting their MX record to localhost.
This dear reader is pure genius.
It is genius because it means that any DNS-aware mail server carrying mail for admin.com will burn up on repeated local delivery attempts my this MX record to localhost forcing the mail server into attempting delivery to itself.
The added bonus of this method is that mail never hits admin.com’s servers thus ensuring that their servers do not serve a dross of spam.
While it is obvious that this method does not allow delivery of mail if you actually want to receive mail, it is only suitable in this uncommon situation, and hmm, maybe some other situations.
It may possibly be a suitable remedy to eliciting noticeable decommissioning of domains such that the receiving SMTP servers catch no load and the sending SMTP servers get to see all the errors.
This may also be a useful spoofing technique for DNS views within your control if you want to suppress mail to certain domains within a subscribed client-base.
Or maybe suppressing mail from a machine which it is not possible to disable applications from mailing out.
A quick ‘hack’ to test this on any given machine is to alias the given domain to localhost in the /etc/hosts or c:\windows\system32\drivers\etc\hosts file in order to elicit the same outcome.
Caution is recommended – don’t lock-out access to key hosts like yourself or the device’s default router by aliasing critical network nodes. Your mileage may vary – don’t alias the name in which your machine has (if known to the device) for which you are using to administer the given device.
Have you ever wondered how search engines actually make their money from advertising?
Have you ever had privacy concerns over the search terms you use?
Have you ever been freaked out by how well targeted modern advertising is?
If you can say yes to any of these – then read on! Otherwise, still read on for an eye-opener.
Search engines only exist because there is a financial model behind them which is there, naturally, to generate profits. So, how do search engines make their profit? Search engines primarily make their money from advertising (as their search and associated services are free to end-users) and they achieve this by three primary techniques:-
Through the many different tracking technologies available- it is easy to identify and build a profile of an Internet user. This data is collected in the form of search engine logs (on their servers) which can then be analysed either in real-time or at a later date, This statistical analysis provides deep insight into what other products and services might be of interest to you in order to elicit targeted marketing, however there can be a far more sinister use for this data too.
This data can be used to profile a person in order to find out things such as:-
All of these are used for profiling you in order to place you within a demographic classification which can then be identified and targeted for a number of uses including advertising.
How are these stats collected? The user normally wilfully gives them without a second thought. Sources such as your favourite search engine, along with Facebook, Twitter, Flickr, and other social media, which is then tied together into continuous sessions using tracking cookies.
Many social media tools like facial recognition on Facebook enable people to be accurately associated with others, another social engineering danger, which usually starts with “do you know ‘so-and-so’?”
Many web pages register your presence with syndication partners merely by viewing the page, for example, Google and Facebook get informed of your visit every time you visit a page with some of their ‘like’ buttons (but not all), so in many cases – even if you don’t click it, you may get tracked. Same for YouTube videos on sites other than YouTube itself – YouTube (and thus Google) will know you’ve visited even if you don’t watch any movies because it will have linked back to YouTube in order to provide the ‘player’ for that shared content. In another example, Amazon’s affiliate advertising syndication could be used to track users across pages which show Amazon affiliate adverts.
An interesting concept on social tracking is that if you use your friend’s wireless with your own equipment then there will be a chance to trace your tracking session transferring to a source of other known tracking sessions, thus it is able to also track your physical movements and correlate you to others through simultaneously sharing the same IP. Your iPhone or Android will go with you everywhere, and wherever there is wireless configured (with the correct password), it will use it and tell on you. Being fair on the matter, the telephone companies can do this far easier through 3G phone networks but being in the same proximity does not always positively prove a relationship – unlike sharing an IP.
It is also possible for ISPs to proxy your web traffic for the purpose of caching content in order to deliver a faster network – this can also be used as a source of data.
Many people simply ‘like’ products, creating for themselves an association with which allows others to gauge your persona because when you ‘like’ a product on Facebook, it tells all of your friends (or at least ‘friends’ on Facebook). This could then be used in social engineering attacks against you. Google track you simply for viewing a page with a Google+ button on it.
Google is so elusive – you need their “opt-out” plugin to avoid them – which as discussed before comes with an auto-update program which still ‘phones-home’.
So, by using social, open-source, and purchased data from many different sources such as Facebook, Twitter, MySpace, Google, Bing! Etc it is easily possible to build an accurate profile of a person, their relationships, and their surfing habits which will reveal insight into that person in order to target them for one purpose or another. This indeed is what the advertisers are after hence this is the reason why this data has value.
While this data has value, this data is also private data about individuals, and it is about your data too, which while a few traces will reveal little about you, long term traces can reveal lots more than you realise. How often do you clear your cookie cache? And do you have ‘Do Not Trace’ set on your web browser?
A recent row has broken out between online advertisers and Microsoft, who have taken the bold step to enable ‘Do Not Trace’ on their latest web browsers, which if you’re not aware is the default action of actively blocking tracking cookies. The advertisers are up in arms – and this tells you a lot about the value of the data.
To protect yourself from this form of personal data leakage, you should choose your web browser and search engines wisely. I am currently using SRW Iron for a web browser because it has all the power and prowess of Google Chrome with all of the Google-phone-home stuff taken out and a few safety features made default, and I use duckduckgo.com for a search engine because it supports encrypted connections through https, it does not record your IP in its logs, and they discard your results after 2 days. Duckduckgo.com also has a search portal within Tor and are strong advocates of internet privacy.
See duckduckgo’s privacy statement here:-

Another search engine worth considering is ixquick, who’s privacy policy can be seen here:-

For comparison, here’s Google’s privacy statement:-
https://www.google.co.uk/intl/en/policies/privacy/
Wow!, need I say more?
It is worth noting that all searches done using standard http can be recorded ‘on-the-wire’ by anyone who is monitoring the traffic. This includes all searches, returned content, and modifications to those searches, often, character-by-character where auto-fill offers search suggestions. For this reason, it is always worth using a search engine which can support https as this will stop a degree (but not all) snooping on the wire.
Another point worth noting is that you often lose protection the second you leave the https encrypted search engine page because you then give away the site which the search engine led you too. In the cases of many search engines, they too track this information, adding to their knowledge base of not only what you searched, but which links you clicked on. Once you click your intended site, you leave the protection of the encrypted search thus revealing your next site, so therefore using an encrypted search does not protect you beyond the initial search you undertake.
So, now knowing the extend of browser tracking, I encourage you to consider this when surfing the Internet, and take measures to protect your privacy.
It always makes me wonder why people click “like” for commercial products and allow themselves to be used as free advertising!
Millions every day give away habits such as gambling and playing online games through their “likes”.
Many also attach themselves to high value products in the vain hope of improving their own self image.
These commercial endorsements serve only to benefit the vendors but have the unexpected consequence of providing very accurate demographics on yourself.
So often I hear about people being concerned with browser cookies – what they are, what they do, and what they tell about you. Well, there’s lots on that already. In this post I recommend that users set their web browsers to clear down all cookies after every session in order to ensure information from one browsing session is not passed to the next. I also recommend the blocking of all 3rd party cookies, and also recommend setting your browser history to “0”. This way, all residual information should be cleared down at the end of each browsing session.
it is of my opinion that Google is evil, or at least their analytics is evil – they are one of the few search engines where you have to install a browser plugin to opt-out! of their analytics, and to make things worse – it comes with an automatic update system which pollutes your windows services and scheduled tasks in order to make it phone home to google anyway! It somehow reminds me of phorm!
Browser search bar plugins are like a plague on your privacy as they send stats on you back to their respective companies – only ever use the simple search set inside the top right or address bar of your browser and set it to something secure like https://duckduckgo.com or https://encrypted.google.com. All search bars which offer any kind of automatic search or auto-completion or ‘safe-search’ filtering will provide all of your web surfing traffic to a 3rd party who may then sell or expose that data. For this reason – all browser search plugins unless absolutely necessary (like when provided as part of a malware scanner) should be avoided like the plague.
Cached passwords are the holy grail of hackers and a principal target for information thieves, for this reason you should never save your password on your workstation and never use the same password across systems.
When prompted to save a persistent authentication token such password, you should always say no or never. The only place for a ‘stored’ password is an encrypted and password protected database (for which it should not have the password written down).
