Open Source BleachBit 0.9.3 – Deletes HTML5 Cookies

I considered just giving up – but, I’ll be damned if I will. I take every precaution I can to guard against the invasive parasitic practices of data collectors who are persistent in their attempts to collect “anonymous” data on my personal browsing habits. But, it’s never enough.

Despite my precautions – despite the tools I use in an attempt to respond to the insidious nature of web tracking – I find myself fighting a constant rear guard action. No sooner do I reach a plateau from which I can exert a functional level of control over the “behind closed doors nature” of Internet tracking – than I’m forced to deal with an even more insidious method of personal data collection.

Let’s spin back for a moment, to the time when the so called LSO (Flash Cookie) was introduced as a response to users gaining control over standard HTTP cookies. Control which allowed for the acceptance, the rejection, and the wiping of private data – including wiping cookies.

The Flash Cookie changed all that. By design, a Flash Cookie (Super Cookie)remains active on a system even after the user has cleared cookies and privacy settings. BetterPrivacy – a free Firefox add-on, stepped into the battle to address this issue, and gave users an opportunity to identify, and delete, Super Cookies.

When a Tracking Cookie is not obvious to a casual Internet user and, when that cookie cannot be deleted without the aid of a specialty cleaner, then Internet tracking has been taken to a level that borders on deception. Hell, let’s call it what it really is – crooked, immoral, fraudulent, illegal, ……..

When I first wrote on Super Cookies in September 2009, I made the following comment –

“……….with little resistance being offered by the “sheeple”,  and a failure by regulatory authorities to enact appropriate consumer protection laws, we can expect privacy intrusions , like this, to accelerate.”

It’s hardly surprising then, that we are now faced with the Evercookie (HTML5 Cookies)

From Wikipedia:

An Evercookie is not merely difficult to delete. It actively “resists” deletion by copying itself in different forms on the user’s machine and resurrecting itself if it notices that some of the copies are missing or expired. Specifically, when creating a new cookie, Evercookie uses the following storage mechanisms when available:

• Standard HTTP cookies
• Local Shared Objects (Flash cookies)
• Silverlight Isolated Storage
• Storing cookies in RGB values of auto-generated, force-cached PNGs using HTML5 Canvas tag to read pixels (cookies) back out
• Storing cookies in Web history
• Storing cookies in HTTP ETags
• Storing cookies in Web cache
• window.name caching
• Internet Explorer userData storage
• HTML5 Session Storage
• HTML5 Local Storage
• HTML5 Global Storage
• HTML5 Database Storage via SQLite

Hold on – there’s more:

The developer is looking to add the following features:

• Caching in HTTP Authentication
• Using Java to produce a unique key based on NIC information.

We’re not quite finished.

With this tool it is possible to have persistent identification of a specific computer, and since it is specific to an account on that computer, it links the data to an individual. It is conceivable this tool could be used to track a user and the different cookies associated with that user’s identifying data without the user’s consent. The tool has a great deal of potential to undermine browsing privacy.

I don’t know what your definition of hacking, or illegal access encompasses – but, in my view, the placement of an Evercookie steps over the line into the realm of cybercrime. I suggest to you, that if a government were to penetrate a user system to plant an Evercookie as a matter of course – the outrage would be immediate. But, private enterprise does it – and the “sheeple” happily bow to what they consider the inevitable.

The tracking industry (a multi-Billion dollar industry), has gone too far on this one. I predict the litigation lawyers, and privacy advocates, will run out the big guns in a justifiable attempt to eradicate this spyware.

Personally, I believe that criminal charges should be laid against the executives of those organizations currently using Evercookie. I see no difference between these yahoos, and Russian cybercriminals.

Additional statistics on which web sites are currently using Evercookies can be had by reading an eye opening article by one of my favorite Tech writers Ed Bott – here.

In the meantime, you might consider installing BleachBit – an open source application which will delete Evercookies from your system.

In the following screen capture I have focused on a Firefox cleanup – including wiping HTML5 cookies.

In this screen capture the focus is on deleting Flash cookies ((Super Cookies).

Lets take a look at a preview of what’s going to be deleted –

Choosing the same parameters using CCleaner (a Flash and Firefox cleanup), leads to a considerable difference.

Fast facts:

BleachBit quickly frees disk space and tirelessly guards your privacy.

Free cache, delete cookies, clear Internet history, shred temporary files, delete logs, and discard junk you didn’t know was there.

Designed for Linux and Windows systems, it wipes clean 90 applications including Firefox, Internet Explorer, Adobe Flash, Google Chrome, Opera, Safari,and more.

Beyond simply deleting files, BleachBit includes advanced features such as shredding files to prevent recovery, wiping free disk space to hide traces of files deleted by other applications, and vacuuming Firefox to make it faster.

Better than free, BleachBit is open source.

System requirements: Window, Linux.

Languages: This application is available in 56 languages.

Download at: SourceForge

BleachBit is a powerful application; I recommend that you spend some time becoming familiar with its operation and capacity, before using for the first time.

Flash Cookies – Spyware By Any Other Name

I first wrote on the issue of Flash cookies back in September 2009, and since then, I’ve watched as these obnoxious web trackers and privacy invaders multiply like a virus. Based on the number of questions I continue to get on the Flash cookie issue, it’s apparent – confusion reigns when it comes to this underhanded privacy threat.

One of the better forum comments I’ve seen referencing Flash cookies:

“I think many people may not realize how serious it is. In many ways, I see it as the virtual equivalent of dumpster diving or taping together a shredded document. It is deliberately ignoring a data owners deletion of data by an entity that has no business doing so.”

This practice of  web sites dropping Flash cookies onto your computer, which occurs without your knowledge or permission, is akin to hacking – according to some in the security community. Frankly, I agree.

Continuing developments in tracking technologies, and a complete disregard for fundamental privacy rights, should be a major topic of conversation in the security community – until such time as the issue has been resolved in favor of consumers.

In the meantime, we’re on our own. It’s up to us, as individual consumers, to take the appropriate steps to safeguard our privacy (as best we can), while interacting with the Internet.

Here’s what we’re up against – and, this is just one small example.

From Disinformation.com

McDonald’s, CBS, Mazda, Microsoft Sued For Tracking Internet Users’ Histories

In a complaint filed Tuesday with the U.S. District Court for the Southern District of New York, Sonal Bose alleges that McDonald’s and the other companies “acted in concert with Interclick,” to mine users’ Web surfing history for marketing purposes. “Defendants circumvented the privacy and security controls of consumers who, like plaintiff, had configured their browsers to prevent third-party advertisers from monitoring their online activities,” Bose alleges.

The lawsuit alleges that the companies violated the federal computer fraud law, wiretap law and other statutes. She is seeking class-action status. This lawsuit comes several weeks after Bose sued Interclick for allegedly using history-sniffing technology and Flash cookies to track her online activity.

History-sniffing technology exploits a vulnerability in browsers to discover the Web sites users previously visited. Researchers from the University of California, San Diego recently brought the technique to light when they published a paper explaining the technique and naming 46 Web sites where history-sniffing technology was being deployed. In at least some cases, ad company Interclick reportedly used the technology without the publishers’ knowledge.

Bose also says in her complaint that she believes that the defendants used Flash cookies for tracking purposes. Flash cookies are stored in a different place in the browser than HTTP cookies, and therefore, require additional effort to delete.

Flash cookie quick facts:

They never expire

Can store up to 100 KB of information compared to a text cookie’s 4 KB.

Internet browsers are not aware of those cookies.

LSO’s usually cannot be removed by browsers.

Using Flash they can access and store highly specific personal and technical information (system, user name, files,…).

Can send the stored information to the appropriate server, without user’s permission.

Flash applications do not need to be visible.

There is no easy way to tell which flash-cookie sites are tracking you.

Shared folders allow cross-browser tracking – LSO’s work in every flash-enabled application

No user-friendly way to manage LSO’s, in fact it’s incredible cumbersome.

Many domains and tracking companies make extensive use of flash-cookies.

If you value your privacy, then without a doubt you need to control these highly invasive objects, and if you are a Firefox user there is a solution – BetterPrivacy – a free Firefox add-on.

From the BetterPrivacy page:

“Better Privacy serves to protect against not delectable, long-term cookies, a new generation of ‘Super-Cookie’, which silently conquered the internet.

This new cookie generation offers unlimited user tracking to industry and market research. Concerning privacy Flash- and DOM Storage objects are most critical.

This add-on was made to make users aware of those hidden, never expiring objects and to offer an easy way to get rid of them – since browsers are unable to do that for you”.

In the following screen capture (click to expand to original), you’ll notice BetterPrivacy has deleted a cumulative total of 6188 Super Cookies.

The Options and Help tab (shown in the following screen shot), will allow you to choose specific deletion methods. You should consider selecting “Disable Ping Tracking”, which will prohibit sites from following you as you surf the Net.

Download at: Mozilla

Take Control Of Your Internet Privacy With BetterPrivacy Firefox Add-on

In the real world of Internet security push and shove, it seems everything has a “season” – a space in the spotlight. For example – each day we are bombarded with the latest, subjectively “most dangerous” – malware threat, cyber criminal operational techniques, application vulnerabilities, or irresponsible enterprise behavior – the latest being the negligent Epsilon data breach. All destined to become “old news” and seemingly irrelevant, within days

Just wait a few days and the Epsilon data breach will no longer be news worthy; it will simple fade away (just as if it never happened) – as have the other 20+ serious data breaches which have occurred in the last 30 days. Data breaches that have impacted governments, educational facilities, major enterprises ……

Test yourself – can you name one other security breach, application vulnerability, or dangerous malware threat, or technique, reported on in the last thirty days?

Internet privacy is a perfect example of this; in favor – out of favor, critical issue – non-critical issue cycle of Internet security push and shove. Lately, Internet privacy has been relegated to the back burner. Sort of like – hey, it’s not a big deal. Besides, there are newer and more exciting issues to report on – Internet privacy is old news!

But here’s the thing – Internet privacy is a substantial issue, and a more critical issue than ever. Developments in tracking technologies and a complete disregard for fundamental privacy rights, should be a major topic of conversation in the security community – until such time as the issue has been resolved in favor of consumers.

In the meantime, we’re on our own. It’s up to us, as individual consumers, to take the appropriate steps to safeguard our privacy (as best we can), while interacting with the Internet.

You can take a step in that direction by increasing your awareness of a significant threat to your privacy – Flash Cookies (also described as (LSO) – Local Shared Objects, and Smart Cookies).

Late last year, I wrote an article “BetterPrivacy Firefox Add-on Kills Flash Cookies”, centered on this stealthy and underhanded privacy threat, which I have now updated. I think you’ll find it’s worth another read.

If you hear something repeated often enough, then that “something” takes on a veneer of truth. It doesn’t necessarily mean that it is true of course – but, it appears to be true. The “truth” regarding Internet site cookies, falls into that category.

Most of us have heard that “truth” – without cookies (and now, Flash cookies), your Web experience would be terrible. You’d be starting from scratch each time you did anything on a given site online. Or, something along that line.

Nonsense! For years, I have deleted cookies at every Browser shut down, and have experienced no perceptible difference in performance when visiting the same 30 or so sites, that I visit every day

Here’s the reality:

Cookies are there for the benefit of advertisers; not the web site visitor – plain and simple. Keep in mind, that it’s critically important to advertisers to generate advertising that is specific to the web site visitor at the time of the visit – not later, but right then. And a cookie is the tool that facilitates this happening.

Luckily, Internet browsers can be set to allow full user control over cookies including accepting, rejecting, or wiping private data which includes wiping cookies. That is, until recently.

It appears that a user’s decision to control cookies, in this way, is simply not acceptable to advertisers and certain web sites, and so, we now have the Flash Cookie (LSO) – Local Shared Objects.

There is a major advantage for an advertiser to employ Flash cookies, not the least of which is; they are virtually unknown to the average user. Equally as important, from an advertisers perspective is; they remain active on a system even after the user has cleared cookies and privacy settings.

This practice of  web sites dropping Flash cookies onto your computer, which occurs without your knowledge or permission,  according to some in the security community, is akin to hacking. Frankly, I agree.

If you think this practice is restricted to shady web sites, you’d be wrong. Of the top 100 web sites, the majority use Flash Cookies. So, I was not particularly surprised, when I found some of my favorite sites involved in this invasive practice.

I first wrote on the issue of Flash Cookies back in September 2009, and since then, I’ve watched as these obnoxious web trackers and privacy invaders multiply like a virus.

Quick Flash cookie facts:

In the following screen capture (click to expand to original), you’ll notice BetterPrivacy has deleted a cumulative total of 6188 Super Cookies. An amazing number, considering the OS on this machine was freshly installed on March 1, 2011.

The Options and Help tab (shown in the following screen shot), will allow you to choose specific deletion methods. You should consider selecting “Disable Ping Tracking”, which will prohibit sites from following you as you surf the Net.

Simple HTTP cookies (ordinary cookies), can be subject to attack by cyber criminals, so it won’t be long before flash cookies will be subject to the same manipulation. Better you should learn how to control them now – not later.

Privacy, in all areas of our life is under constant attack, but that shouldn’t mean that we give up. We need to learn to fight back with every tool that’s available.
