Microsoft\u2019s InPrivate browsing is supposed to help you \u201csurf the web without leaving a trail\u201d and InPrivate browsing mode can be used in Edge. Microsoft says, \u201cWhen you use Microsoft Edge in InPrivate mode, your browsing information, such as cookies, history, or temporary files, aren\u2019t saved on your device after your browsing session has ended. Microsoft Edge clears all temporary data from your device.\u201d Yet InPrivate browsing with Edge is a fail as it is not private and instead keeps browsing history.Hmm, if that sounds a bit familiar it might be because it\u2019s been said before. In September, computer forensic analyst Brent Muir wrote, \u201cJust how private is InPrivate Browsing mode in Microsoft Edge? Not as private as Microsoft would lead you to believe."He added that Microsoft Edge \u201cisn\u2019t that private after all. If you are hiding from a spouse\/partner then it may suffice but if you are trying to cover your tracks you\u2019d better guess again, any good forensicator will be able to identify and recover your browsing history in a matter of minutes.\u201d Incidentally, if you are interested, Muir also has slides about various Windows 10 evidentiary artifacts.Muir isn\u2019t alone in advising against using Edge\u2019s not-so-private InPrivate browing. When questioned about similar findings by forensic researcher Ashish Singh, the Microsoft PR machine jumped into action. \u201cWe recently became aware of a report that claims InPrivate tabs are not working as designed and we are committed to resolving this as quickly as possible,\u201d a Microsoft spokesperson told The Verge.Aw, isn\u2019t that cute? Microsoft cares. Yet it is perplexing as to what \u201crecently became aware\u201d actually means since the original forensic research article was published in October. The issue was kicked to the forefront by BetaNews which advised users to \u201cstop using Microsoft\u2019s Edge\u2019s InPrivate mode if you value your privacy.\u201dBut when checking it out, the forensic article seems to have poofed even though retrieving InPrivate artifacts are discussed elsewhere on Forensic Focus. My interest was piqued. Thankfully there is a January 30 cached copy of Singh\u2019s research \u2013 captured for prosperity \u2013 to save the day.Singh goes through the \u201csearch for evidence,\u201d detailing the artifacts left behind after using Edge InPrivate browsing mode. He then added, \u201cThe forensic examination of most web browsers has proven that they don't have a provision for storing the details of privately browsed web sessions. Private browsing is provided for a purpose, i.e. privately browsing the web, which is being delivered.\u201dHowever, in Microsoft Edge, \u201cthe private browsing isn't as private as it seems,\u201d explained Singh. \u201cPrevious investigations of the browser have resulted in revealing that websites visited in private mode are also stored in the browser\u2019s WebCache file.\u201dSingh concluded:Therefore any skilled investigator can easily spot the difference and get concrete evidence against a person\u2019s wrongdoings. Plenty of artifacts are maintained by the browser, which makes examination quite easy. However, there are stages where evidence is not so easy to find. The not-so-private browsing featured by Edge makes its very purpose seem to fail.Seriously, if you really care about your privacy and you are using Edge at all then I\u2019m concerned for you. The same might be said of all Microsoft products, but that\u2019s the way the world rolls and you likely do use Microsoft. Regarding private browsing, you would be better served to use the Tor browser which implies Firefox.
