Microsoft Edge's Private Browsing Mode Isn't Actually Private (betanews.com)
JustAnotherOldGuy writes: The forensic examination of most web browsers has proven that they don't have a provision for storing the details of privately browsed web sessions. However, in the case of Microsoft Edge, the private browsing isn't as private as it seems. Previous investigations of the browser have resulted in revealing that websites visited in private mode are also stored in the browser's WebCache file. The Container_n table stores web history, and a field named 'Flag' with a value of '8' shows that website was visited in private mode. An investigator can easily spot the difference and use this evidence against a person. The not-so-private browsing featured by Edge makes its very purpose seem to fail, and you can't help but ask how such a fundamental aspect of private browsing could be so fantastically borked. It beggars belief.
I would say, it's just not a surprise anyone here. An antonym of privacy or security is Microsoft.
So, InPrivate is to Private as InVisible is to Visible.
The rest of us have been here also, all along, but just in "Private Mode". There are actually 1203 "first posts" before yours. Look harder. :-)
seems editors here used all knowing edge, which explains delay in accessing to this old story.
It's worth noting that other browsers' "private browsing" modes only hide the details of the session from the local machine. Using "incognito mode" in Google Chrome is not encryption and does not shield your privacy in any way from others on your network, your ISP, the NSA or Google themselves.
Proof? I think security researchers looking into this would've noticed packets going out encrypted or not during privacy mode.

It "beggars belief" why this editor still works at /.
I'm not sure why I'm feeding the trolls (troll being the summary itself).
I'd appreciate an actual "private" mode, but none of the browsers do what I'd expect from that. My expectation would be that the browser would behave as if it is a clean slate, not store anything to disk, possibly encrypt or at least attempt to hide memory contents, and possibly attempt to hide other identifying details (screen resolution, "agent" header string, plugin list, etc).
Personally, I find little benefit to the make believe "private" mode in that it hides its actions from my own computer. I am not worried about other legitimate users of my computer finding out secrets about me (and if I was, I'd use something much more hidden than "private" mode - another vm with encrypted drives, powered off or in hibernate when I'm not using it).
With that in mind, this info seems to be quite an exaggerated diff between the various private mode expectations. Not that I care much as long as the behavior is what it is, but what I'd want to know is:
* can normal, unprivileged user accounts access these history records?
If not, then it's doing its job just about as well as any of the others.
By "illegal" I mean a civil violation of warranty- and false-advertising laws that say products are supposed to meet their intended purpose, as a common everyday consumer would understand the term "intended purpose."
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
Wrong. I don't know about Google, but I do know about Safari. When it's in private mode, all of the data that is normally saved to disk for any purpose is stored in encrypted memory, so within a private session, you get the benefit of caching, go forward/back, etc. But once you close the private window, all that encrypted memory is erased and released. Apps using the NSURLSession APIs can do exactly the same thing.
I've concluded in the past couple of years that large parts of Microsoft as an organization have stopped being able to coherently sell to the end user market, and whatever people in the management that would have in the past noticed this sort of thing and taken steps to correct it have left or moved on to other roles.
Signs of things slipping I've personally noticed in recent years:
- The faulty Microsoft web-based store (do they expect developers whose first experience with Microsoft is a web site that can't even sell a Windows upgrade are going to turn around and want to build things on ASP.net?)
- Contradictory descriptions of the different Windows SKUs (with respect to use as upgrades, new machine installs, usability by end users vs. system integrators, etc.)
- Software with seriously flakiness in features that worked in previous versions (e.g. Windows 10 Start Menu search and keyboard navigation), with broken help links, without an integrated installer (e.g. Lync, Sharepoint)
well private mode is starting to be just "adblock disabled" mode for them...

Microsoft Edge's Private Browsing Mode Isn't Actually Private
I'm shocked! Shocked, I tell you!
On the other hand, it has been obvious to me for a long time that if you want privacy, you don't use Microsoft products.
I'm an American. I love this country and the freedoms that we used to have.
Modern app appers know that only apps can app apps, and privacy is something only LUDDITES use, so apps like Edge app everything you app so every apper can app your apps while apping other apps!
Apps!
not a bug.
This is Microsoft we're talking about. Misrepresentation about their products is what they do.
You're thinking of "implied warranty of fitness for a particular purpose ", as it's called in the Uniform Commercial Code. There's also warranty of merchantability. Let's look at each in turn.
The terms and conditions can explicitly and clearly disclaim the warranty of fitness for a particular purpose, and I'm sure Microsoft's terms do so. They can't disclaim warranty of merchantability so easily. If they do disclaim fitness for a particular purpose, that's the end of that. If they didn't disclaim the warranty, UCC has two conditions. First, the seller must have reason to know what purpose the buyer intends to use it for - browsing porn without having the address bar later autocomplete xvideos.com? National security level espionage? Secondly, the seller must habe reason to know that the buyer is relying on the seller's expertise to recommend an appropriate product.
Microsoft doesn't know whether you intend to use it to avoid having autocomplete accidentally embarrass you or if you're trying to foil expert forensic investigators. Since they don't know which purpose(s) you might use it for, there is no warranty of fitness for a particular purpose.
On to warranty of merchantability. This applies even when the seller does NOT know what purpose you plan to use it for. Because the seller doesn't know, he warrants only that it's useable for SOME purpose. If the mode successfully avoids accidental embarrassment from autocomplete, accidentally hitting the back button down-arrow, etc, then it is useful for SOME purpose and therefore the warranty of merchantability is met.
Suppose some warranty was NOT met (and not successfully disclaimed). Then you could sue Microsoft for actual damages. If you prove that an accidental autocomplete during a business presentation got you fired, they would need to compensate you for the lost pay.
Lastly, you mentioned false advertising. What exactly do Microsoft's ads say about the feature? I suspect they do not say "prevents forensic examiners from determining anything about your browsing history".
Exactly, it wouldn't have surprised me if they sent private browsing data direclty to their Redmond office.
you're telling me that a corporation that is notorious for their flawed software has made a flawed browser?! impossibru!
Anons need not reply. Questions end with a question mark.
Even so, if you put the safety on on your gun, that doesn't make the weapon truly and completely safe and nobody is suggesting it does.
But can you imagine if putting the safety on merely lowered the muzzle velocity by 5%?
Or a door lock that simply turned a red LED on some dashboard somewhere labelled locked, and nothing else.
There is not, and never will be, a truly "private" browsing experience, regardless of browser.
But some browsers actually do a little more than next to NOTHING to remove the session history from the local PC.
Microsoft has gone full-blown Big Brother/1984; is anyone at all surprised that their newest browser is also spying on you?
Go right ahead and mod me down to negative one troll, Microsoft shills, I expect it of you; wouldn't want your corporate masters to be angry with you, now would you? By the way I'm going to just keep on lambasting Microsoft ad infinitum, and anyone that doesn't like it can, quite frankly, suck my dick.
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
It isn't a surprise.
But in MS's credit Google and Apple both do the same thing too
How does other people doing "the same thing too" work to Microsoft's credit or speak in any way to merits of underlying issues?
This line of argument is nothing more than bandwagon fallacy. It's completely worthless.
Thats why I do my really serious browsing in a new VM that is read-only. After, I delete the vm. Then light the computer on fire.
Chrome Incognito mode is the same. One of the drawbacks being that if you accidentally close a tab, you can't undo it. That tab is gone for good. I don't think it's encrypted in memory though, so if Windows pushes it to the pagefile it could (temporarily) be written to disk.
Sounds like, from the description, that it is working as designed.
No sig. Move along - nothing to see here.
Obviously the web site you visit knows you were there, but if a browser implies it erases its end of the session then it should do so.
You always need to have the "Internet Explorer Enhanced Security Configuration" feature turned on for your privacy you insensitive clods!!
Considering how much spying is baked into Windows 10 frankly the thought that anything done in that OS is "private" is beyond belief.
ACs don't waste your time replying, your posts are never seen by me.
One man's cache is another man's treasure.
How am I meant to browse for gifts and flowers for my wife (WHICH IS ALL ANYONE EVER DOES WITH PRIVATE BROWSING) if its not actually private? Oh and in case the wife does find traces of activity, yes cumgarglingsluts.com is a site that sells flowers and gifts. Way to ruin the surprise Edge.
They invented unsafe OS with user processes running in kernel mode.
They invented the mail-transported virus, when outlook auto-executed attachments received by email
They invented web vulnerabilities with activeX (Execute code found on web pages - no need to look for buffer overflows when this sort of thing is designed in.)
So indeed, no surprise from microsoft here.
>>Then light the computer on fire
Good job your computer is flammable. No, inflammable. Damn!
PS, I've always understood both words to mean the same thing. What's with the suggestion that they have subtly different meanings. No,forget it. I couldn't care less. :-)
Not just Win10. I am always reviewing the logs of my Router (a home brewed Ubuntu server box), and I was surprised when Android also connects to Redmond HQ of Microsoft. Here's the IP being contacted by Android but there are a bunch of other MSFT IPs.
some MS IP being contacted by by Android device:
40.113.87.220
111.221.77.144

Makes one wonder why Microsoft keeps on connecting to Android devices 24/7 even at 2 am when everybody is asleep.
Is why anyone believes things like MS's browser not being "private" is a mistake, or Apples "goto" fail was a bug (some of many fails for both corps) or that there isn't an obvious collusion between the gov and the tech sector, and all the spying and dirty tricks you see are not "bugs" or "mistakes" they were planned all along.
Eisenhower warned us, we didn't listen, it came to be, now we are "proper fucked".
"If any question why we died, Tell them because our fathers lied."
So, Microsoft came out with brand new technology ... tells us how awesome, secure, and private it is.
And, shockingly, it isn't.
Why anybody is surprised that Microsoft hasn't really got a mature enough product to know how secure it is makes no sense.
Why anybody would believe that after all these years Microsoft suddenly wrote a secure browser is beyond belief.
Did anybody believe Edge was magically safe and secure just because Microsoft said so?

Call me a conspiracy nut, I don't care, but *somebody* has got to step up to the plate to fill that giant NSA datacenter in Utah.. I suspect MS has partnered with the NSA to do that very thing, and the way MS is trying to shove Windows 10 down the throats of all of the poor schlubs who still use Windows makes this "conspiracy theory" damn near a sure thing. Given that and the way they're force-feeding the telemetry crap on Windows 7/8/8.1.... Sooooooooooooooo glad I quit sucking on the MS teat...
THANK YOU, Edward Snowden!! Americans owe you a debt of gratitude (whether they know it or not..)
It's private in the sense that they know that that they're tracking you and you don't.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Sadly, with LSOs, various browser fingerprinting mechanisms, and many other items, the only thing that might might equate to a "private mode" would be to turn on automatic rolling back of a VM when it shuts down, or perhaps having a VM which uses a provisioning script to auto-install the browser and generate a new machine ID every so often, fetching and reloading one's bookmarks and other essential add-ons from a provisioning server. At least with Vagrant, cracking off a new VM configured how you like it for browsing isn't too bad.
I'm not sure if it's Android in general or Samsung specifically but I've noticed that my Galaxy S6 Edge uses word-completion suggestions culled from browser usage in incognito mode.

As a matter of fact, isn't the browsing history the basis for the (in)famous crashsafari dot com?
My eyes reflect the stars and a smile lights up my face.
There are a lot of posts talking about what an incognito mode should do. Normally we refer to it as 'porn mode' here on /. which does seem to be the intended use case. There's a lot of reverse-engineered information out there about what these modes actually do. In reality, it's insane to trust any closed-source browser with this type of task. If you really care about this feature, you'll want to use an open-source browser where the source code can be audited to determine exactly what it was *intended* to do. (New security issues pop up all the time WRT things not behaving as intended, but that's a separate issue). And the behavior should be documented so you can decide if it meets your need.
And yet, no browser that I am aware of flushes the DNS cache on the system (even though they could if they were truly trying to make a "private" experience).
My eyes reflect the stars and a smile lights up my face.
Yeah, because inspecting the browser's cache file is within the skill level of so many people....
My eyes reflect the stars and a smile lights up my face.
its microsoft, enough said, TOTAL FAIL
Is why are you relying on your web browser to provide you with the security to break laws, that's not what private/incognito are for.
It's to prevent other users on the machine from seeing your browser history...
I put in the little effort to setup classic IE on my win10 tablet because edge was basically unusable due to the fact it doesn't have an ad blocker. I really have no idea how people can surf the modern internet without an ad blocker, the auto-playing videos and popups everywhere make it completely insane.
At Microsoft the security badge logo goes on the package before the security is added, comrade.
Trust in the computer!
-- Tigger warning: This post may contain tiggers! --
Yeah, you are right. After thinking about if for 2 seconds (which I apparently didn't do when I posted...) you would need to be running as an administrative user in order to flush the system DNS cache. On a shared system this could also lead to unexpected results.
Still, this highlights the point, no browsing is truly private.
My eyes reflect the stars and a smile lights up my face.
well with that, I think the appropriate reaction is to nuke it from orbit, just to be sure.
I was doing this for a while, but realized that a sufficiently advanced attacker could learn things from the combustion products. I now throw the computer into a volcano.
I was going to suggest throwing it into a black hole, but hawking readers are easy to get on newegg.
