Microsoft said in early October that it was aware of only a single threat actor exploiting the vulnerabilities and that the actor had targeted fewer than 10 organizations. The threat actor is fluent in Simplified Chinese, suggesting it has a nexus to China. A third zero-day is CVE, a critical Windows vulnerability that also allows a threat actor to execute malicious code remotely.

Because TAG tracks hacking backed by nation-states, the discovery likely means that government-backed hackers are behind the zero-day exploits. Two more zero-days are escalation-of-privilege vulnerabilities, a class of vulnerability that, when paired with a separate vulnerability or used by someone who already has limited system privileges on a device, elevates system rights to those needed to install code, access passwords, and take control of a device.

As security in applications and operating systems has improved in the past decade, so-called EoP vulnerabilities have grown in importance. The last zero-day fixed this month is also in Windows. CVE allows hackers to create malicious files that evade Mark of the Web defenses, which are designed to work with security features such as Protected View in Microsoft Office.

Windows 7 will also receive security patches, despite falling out of support in Microsoft said the flaw requires that an attacker already has access to a compromised device, or the ability to run code on the target system.

Microsoft credited four different sets of researchers from CrowdStrike, DBAPPSecurity, Mandiant and Zscaler for reporting the flaw, which may be an indication of widespread exploitation in the wild. Microsoft did not share details about the attacks exploiting this vulnerability and did not respond to our request for comment.

Spectre-BHB is a variant of the Spectre v2 vulnerability , which can allow attackers to steal data from memory.

 
 

 

Windows Security: Microsoft Confirms 4 New Zero-Day Attacks

 

The issue risked data leaks across the same clusters, but the firm was quick to note that it found no indication of active exploits. However, the sign-up cut-off is soon approaching, with the date set for September Those eligible will receive invites on both the PC and Xbox platforms.

As for the changes, Industries detailed the tweaks it is planning to make based on the first technical preview’s feedback. For those excited about Alan Wake Remastered , screenshots of the game appeared on Amazon UK before the official announcement arrived with details on the changed elements and PC system requirements.

An extended look at Marvel’s Midnight Suns also came this week in the form of visceral gameplay footage. Considering that the footage is of the game in its alpha stages, the animations and visuals were still unpolished but gave a better look at the villains.

However, only Fallout 1st subscribers will be able to host Custom Worlds. Xbox Game Pass Ultimate subscribers, luckily, will receive Fallout 1st subscription for one month. For Forza Horizon 5 fans, we have listed the current list of cars confirmed by Playground Games , which is over in number.

Cars from the likes of BMW and Tesla are obvious omissions and there is no word on whether they are expected later. This time, central European nations are receiving love, including Austria, Germany, and Switzerland. As usual, there are a bunch of new airports, New Bush Trips, landing challenges, and Discovery flights, and overall improvements to the visuals in those countries.

When Windows 11 began being offered to testers, it was discovered that Windows 11 Home users could not complete the setup process without an internet connection. We found out a workaround , which was soon patched. Now, there is yet another way to bypass this block, which we have detailed in our guide here.

Thank you for taking part. However, Naceri soon discovered that the patch itself was flawed, and published a proof-of-concept that showcase how an attacker could still abuse the vulnerability.

Ideally, as soon as critical content is available, an organization will have the tools available to push updates in real time to all customers without having to upgrade or update the sensor. An attacker can send a maliciously crafted Microsoft Office or RTF document via email to invoke remote code execution when run. Organizations need prevention and detection capabilities that can immediately shut down attack attempts such as these.

As reported , an attacker can leverage non-document techniques — such as a wget request from PowerShell to an attacker controlled domain — to retrieve an HTML payload to further actions on objectives via remote code execution.

In simple terms, the proof-of-concept shows how a hacker can replace any executable file on the system with an MSI file using the discretionary access control list DACL for Microsoft Edge Elevation Service. Microsoft rated the vulnerability as “medium severity,” with a base CVSS Common Vulnerability scoring system score of 5. Now that a functional proof-of-concept exploit code is available, others could try to further abuse it, possibly increasing these scores.

At the moment, Microsoft has yet to issue a new update to mitigate the vulnerability. Naceri seems to have tried to patch the binary himself, but with no success. Until Microsoft patches the vulnerability, the Cisco Talos group recommends those using a Cisco secure firewall to update their rules set with Snort rules and to keep users protected from the exploit.

 
 

– Windows 11 zero day vulnerability – windows 11 zero day vulnerability

 
 

CISA orders agencies to patch new Windows zero-day used in attacks. Hackers steal crypto from Bitcoin ATMs by exploiting zero-day bug. I fail to understand why anyone would seek a bug bounty from Microsoft in the first place They simply maintain Monopoly Control from your hard work so they don’t have to work Stop paying for your own enslavement!

A bug bounty is where a company such as Microsoft pays you for reporting a vulnerability. If you don’t want to do it, then that’s OK, because there are plenty of people who enjoy earning tons of money from companies for helping them discover their security issues. The complaints in the story indicate they are NOT making tons of money? Didn’t you read that far? Some-Other-Guy Microsoft has apparently reduced some of their payouts for reported vulnerabilities, however it didn’t say all of them.

Bug bounty has at least some revenue.. I agree with you and the worst is Windows “Insider” aka unpayed betatester. People are blind.. Very True! You have to guess that ethics don’t mean much to Naceri. With Microsoft, there is no need to guess. You think threat actors are going to bleeping computer for their zero days? This article helps make defenders aware.

Closing your eyes will not mean that the Exploint does not exist. In some ways, I think it is good that the information about Exploits is shown to the “public”. This forces the responsible companies to act. No such vulnerability if you purged Edge from your system I would love to be able to get rid of “Edge” permanently but as usual MS keeps shoving it in our faces insisting that we like it.

If you know a way to permanently remove it and not have it come back please reveal the method. Thank you kindly. You dont need Windows. Windows needs you. The release build 32bit from Naceri doesn’t appear to work on a 64bit system unless IIS is installed. True for others testing the concept and how systems may be compromised? Was it found being actively exploited in the wild? Not a zero-day. A vulnerability does not have to be actively exploited to be a zero-day. It just needs to be publicly disclosed without an available patch.

As for it being abused, yes, it has now been detected used by malware. How can I stop my browser from redirecting. This is a bounty account take over or something, someone reporting my device usage using targeted advertising, they are also on my google account , everything I do, he monitors and report it very wrongly causing me and my usage difficulty.
