To exploit the flaw, Caballero says that an attacker can use server redirect requests combined with data URIs, which would allow him to confuse Edge’s SOP filter and load unauthorized resources on sensitive domains. The expert explains the attack step by step on his blog.
In the end, the attacker will be able to inject a password form on another domain, which the built-in Edge password manager will automatically fill in with the user’s credentials for that domain. Below is a video of the attack.

Ok, maybe not…but its very likely that if you are reading this and find yourself needing to SSH here and there, you also use GIT. Well many are unaware that git for windows bundles several Linux familiar tools. Many might use these in the git bash shell.
That means that when Microsoft showed Windows 10 overtaking Windows 7, this apparently happened in August last year. Most other analysts don’t see that seismic shift happening globally until December 2017, at the earliest.
Microsoft does not intend to gather sensitive information, such as credit card numbers, usernames and passwords, email addresses, or other similarly sensitive information for Linguistic Data Collection. We guard against such events by using technologies to identify and remove sensitive information before linguistic data is sent from the user’s device. If we determine that sensitive information has been inadvertently received, we delete the information.
The CyanogenMod team has posted an update of their own, confirming the shutdown of the CM infrastructure and outlining a plan to continue the open-source initiative as Lineage, which we suspected was going to be the case last week.
The exploit ending in .flac works as a drive-by attack when a Fedora 25 user visits a booby-trapped webpage. With nothing more than a click required, the file will open the desktop calculator. With modification, it could load any code an attacker chooses and execute it with the same system privileges afforded to the user. While users typically don’t have the same unfettered system privileges granted to root, the ones they do have are plenty powerful.
Here’s a blurb from the researcher’s blog post about this:
Resolving all the above, I present here a full, working, reliable, 0day exploit for current Linux distributions (Ubuntu 16.04 LTS and Fedora 25). It’s a full drive-by download in the context of Fedora. It abuses cascading subtle side effects of an emulation misstep that at first appears extremely difficult to exploit but ends up presenting beautiful and 100% reliable exploitation possibilities.
The vulnerability, a variety known as a race condition, was found in the way Linux memory handles a duplication technique called copy on write. Untrusted users can exploit it to gain highly privileged write-access rights to memory mappings that would normally be read-only. More technical details about the vulnerability and exploit are available here, here, and here. Using the acronym derived from copy on write, some researchers have dubbed the vulnerability Dirty COW.
The tactics Microsoft employed to get users of earlier versions of Windows to upgrade to Windows 10 went from annoying to downright malicious. Some highlights: Microsoft installed an app in users’ system trays advertising the free upgrade to Windows 10. The app couldn’t be easily hidden or removed, but some enterprising users figured out a way. Then, the company kept changing the app and bundling it into various security patches, creating a cat-and-mouse game to uninstall it.
And while users can disable some of these settings, it is not a guarantee that your computer will stop talking to Microsoft’s servers. A significant issue is the telemetry data the company receives. While Microsoft insists that it aggregates and anonymizes this data, it hasn’t explained just how it does so.
