Razer Device Plug-In grants Admin Rights on Windows 10 OS

 

A zero-day vulnerability in Razer external device installation software – be it a razer mouse, a keyboard, or any other equipment using the synapse program – offers complete admin privileges to the admin using Windows 10 by plugging and installing a relevant peripheral system. 

Razer is indeed a prominent developer of gameplay mouses and keyboards and is known for providing the best computer accessories. Razer Inc. is a multinational corporation in Singapore that creates, manufactures, and sells electronics, financial services, and games consoles for consumer products. 

However, talking about windows 11, there isn’t any proof yet if it allows the same privileges to the user or not while pugging Razer peripherals. Whereas the vulnerability has nothing with it that won't allow a user to gain access but since the testing on windows 11 hasn’t been done yet, speculations cannot be made. 

In this case, the OS immediately downloads and starts the system installation of the Razer Synapse software whenever users plug a Razer hardware into Windows 10 computer system. Razer Synapse is software that enables users to set up hardware, macros, or map buttons for their hardware devices. 

Security researcher Jonhat (@j0nh4t) disclosed the flaw and tweeted about it on Twitter on Saturday 21st August, after not receiving any response from Razer initially. The tweet had been receiving attention from Razer as of Sunday 22nd August and the maker has told Jonhat that their cybersecurity team is working on a patch for this issue, to fix it at the earliest. Perhaps they gave Jonhat a bug bounty reward as well.  

In the words of the researcher, as well as Bleeping Computer too has proved in the testing itself, that Windows automatically selects an installer containing driver software and a synapse utility when a user plugs into a Razer device (or dongle if this is a wireless device). The activation of Razer Synapse Plug-and-play enables users to obtain SYSTEM permissions on the lickety-split Windows device because it displays an Explorer window as part of the set-up process, which tells users where and how to set up the driver. 

The topmost user permission level in Windows is SYSTEM Privileges: A SYSTEM account enables someone to acquire full control over the system, permitting them to see, alter or delete data; to establish new accounts having full privileges of users, and to install anything – malware included. 

The installation method for Synapse, in other terms, works with Windows 10 with the maximum privileges. The installation application Razer was given the very same administrator rights as the RazerInstaller.exe executable with SYSTEM privileges, which has been launched via a Windows process. 

Jonhat has established that a "Choose a Folder" popup will be displayed if a user decides to modify the default installation folder location. One may right-click the installation window and click the Shift key which launches a certain PowerShell terminal with the same privileges. 

Similar problems are probably identified in other products installed through Windows plug-and-play processes, as indicated by Will Dormann, a CERT/CC vulnerability analyst.

Microsoft Azure Credentials Exposed in Plaintext by Windows 365

 

Mimikatz has been used by a vulnerability researcher to dump a user's unencrypted plaintext Microsoft Azure credentials from Microsoft's new Windows 365 Cloud PC service. Benjamin Delpy designed Mimikatz, an open-source cybersecurity software that allows researchers to test various credential stealing and impersonation vulnerabilities.

Microsoft's Windows 365 cloud-based desktop service went live on August 2nd, allowing customers to rent Cloud PCs and access them via remote desktop clients or a browser. Microsoft offered free virtual PC trials, which rapidly sold out as consumers hurried to receive their two-month free Cloud PC. 

Microsoft announced their new Windows 365 cloud-based virtual desktop experience at the Inspire 2021 conference, which allows organizations to deploy Windows 10 Cloud PCs, as well as Windows 11 eventually, on the cloud. This service is built on top of Azure Virtual Desktop, but it has been modified to make managing and accessing a Cloud PC easier. 

Delpy told that he was one of the lucky few who was able to receive a free trial of the new service and began testing its security. He discovered that the brand-new service allows a malicious programme to dump logged-in customers' Microsoft Azure plaintext email addresses and passwords. The credential dumps are carried out using a vulnerability he identified in May 2021 that allows him to dump plaintext credentials for Terminal Server users. While a user's Terminal Server credentials are encrypted when kept in memory, Delpy claims he could decrypt them using the Terminal Service process. 

To test this technique, BleepingComputer used a free Cloud PC trial on Windows 365. They entered the "ts::logonpasswords" command after connecting through the web browser and started mimikatz with administrative privileges, and mimikatz promptly dumped their login credentials in plaintext. 

While mimikatz was designed for researchers, threat actors frequently use it to extract plaintext passwords from the LSASS process' memory or perform pass-the-hash attacks utilizing NTLM hashes due to the power of its different modules. Threat actors can use this technique to spread laterally across a network until they gain control of a Windows domain controller, allowing them to take control of the entire Windows domain.

To protect against this method, Delpy recommends 2FA, smart cards, Windows Hello, and Windows Defender Remote Credential Guard. These security measures, however, are not yet accessible in Windows 365. Because Windows 365 is oriented toward enterprises, Microsoft is likely to include these security protections in the future, but for the time being, it's crucial to be aware of the technique.

Microsoft Released Security Updates that Block PetitPotam NTLM Relay Attacks

 

The PetitPotam NTLM relay exploit, which allows a threat actor to take over a Windows domain, has been blocked by Microsoft security patches. Gilles Lionel, nicknamed Topotam, a security researcher, revealed a new method called PetitPotam in July that forces a domain controller to authenticate against a threat actor's server utilizing the MS-EFSRPC API capabilities. 

Gilles Lionel published a proof-of-concept (PoC) exploit for a brand new PetitPotam security flaw on July 23, 2021. This problem affected Microsoft's Active Directory Certificate Services (AD CS), which is needed to assure public key infrastructure (PKI) server functionality. 

According to the SANS Institute's Internet Storm Center, PetitPotam uses the Encrypting File System Remote Protocol (MS-EFSRPC) to start the authentication process in remote Windows instances and force them to divulge the NTLM hashes to the adversary. The attacker specifically exploits LSARPC to force any targeted server, including domain controllers (DCs), to connect to the malicious random server and perform NTLM authentication. As a result, the adversary acquires an authentication certificate that is valid for all domain services, including the DC. 

Despite the fact that the PetitPotam attack had devastating results and was simple to launch, the adversaries faced some constraints. To transfer the stolen credentials back to the DC or other internal instances, threat actors needed to achieve SYSTEM/ADMIN rights or maintain covert malicious infrastructure within the LAN, according to the researchers' findings. 

The majority of supported Windows versions, according to the researchers, are vulnerable to the PetitPotam. The technique has been successfully applied to Windows 10, Windows Server 2016, and Windows Server 2019. 

Microsoft provided a security update in August 2021 Patch Tuesday, that prevents the PetitPotam vector (CVE-2021-36942) from forcing a domain controller to authenticate against another server. "This security update blocks the affected API calls OpenEncryptedFileRawA and OpenEncryptedFileRawW through LSARPC interface," explains Microsoft in the CVE-2021-36942 advisory. 

Installing this update may damage backup software that uses the EFS API OpenEncryptedFileRaw(A/W) function, according to Microsoft. "The EFS API OpenEncryptedFileRaw(A/W), often used in backup software, continues to work in all versions of Windows (local and remote), except when backing up to or from a system running Windows Server 2008 SP2. OpenEncryptedFileRaw will no longer work on Windows Server 2008 SP2," warns Microsoft.

Microsoft Edge’s Security Bypass Vulnerability Fixed

 

Microsoft released Edge browser upgrades last week that addressed two security flaws, one of which is a security bypass flaw that may be used to inject and execute arbitrary code in the context of any website. The flaw, dubbed CVE-2021-34506 (CVSS score: 5.4), is caused by a universal cross-site scripting (UXSS) bug that occurs while using Microsoft Translator to automatically translate web pages using the browser's built-in feature.

Microsoft Edge is a cross-platform web browser that was created by the company. It was first released in 2015 for Windows 10 and Xbox One, followed by Android and iOS in 2017, macOS in 2019, and Linux in October 2020 as a preview. Edge was originally designed with Microsoft's proprietary EdgeHTML and Chakra JavaScript engines, resulting in a version known as Microsoft Edge Legacy. 

On January 15, 2020, Microsoft announced the public release of the new Edge. Microsoft began rolling out the new version via Windows Update in June 2020 for Windows 7, 8.1, and Windows 10 versions released between 2003 and 2004. From March 9, 2021, Microsoft stopped issuing security fixes for Edge Legacy, and on April 13, 2021, Microsoft delivered a security upgrade that replaced Edge Legacy with Chromium-based Edge. 

Ignacio Laurence, Vansh Devgan, and Shivam Kumar Singh of CyberXplore Private Limited are credited with finding and reporting CVE-2021-34506. "Unlike the common XSS attacks, UXSS is a type of attack that exploits client-side vulnerabilities in the browser or browser extensions in order to generate an XSS condition, and execute malicious code," CyberXplore researchers said. "When such vulnerabilities are found and exploited, the behavior of the browser is affected and its security features may be bypassed or disabled."

The researchers discovered that the translation feature contained a flaw in the code that failed to sanitise input, allowing an attacker to potentially inject malicious JavaScript code anywhere on the webpage, which is then executed when the user clicks the prompt in the address bar to translate the page. The researchers demonstrated that adding a comment to a YouTube video written in a language other than English, together with an XSS payload, may activate the attack as a proof-of-concept (PoC) exploit. 

In a similar vein, a Facebook friend request with other language content and the XSS payload was discovered to run the code as soon as the recipient checked out the user's profile. Following a responsible disclosure on June 3, Microsoft corrected the problem on June 24 and gave the researchers $20,000 as part of its bug bounty programme.

Golang: A Cryptomining Malware that Maybe Targetting Your PC


Cybersecurity experts at Barracuda Networks have discovered a unique kind of crypto mining malware called "Golang." The malware can attack Windows as well as Linux systems, according to the experts. This latest malware is targeting Monero cryptocurrency with the help of Xmrig, a popular miner. The number of attacks related to the malware may be relatively low, but the cybersecurity experts have discovered 7 IP addresses associated with this malware, all originating from China.


The experts also observed that the Golang malware's primary targets are non-HTTP features like MSSQL and Redis, app servers, web apps frameworks, whereas easy to attack targets like end-users are safe. If we look back into the issue, we will find that the earlier versions of Golang only affected the Linux systems; however, the present version targets Windows and the former. The attacks are carried out using various exploits such as IoT devices, Hadoop, Drupal, ElasticSearch, and Oracle Weblogic. For instance, in a recent malware attack in China, the malware used exploits that targeted ThinkPHP app frameworks widely used in the country.

According to the experts, the Golang malware is capable of evolving every day and using more exploits as each day passes by. Golang malware works by infiltrating the system, and once it does, it uses required files to complete the task. These may include downloaded update scripts, configuration files, scanner, and a miner. It all depends on the type of platform. Whereas, when attacking Windows, the hackers can use backdoors too. In recent times, more and more hackers have shifted towards using Golang as it can't be identified by anti-virus software.

The malware is infamous for targeting vulnerable servers, making it accessible among cybercriminals looking for vulnerabilities to exploit. The only way to be safe from this malware is to keep track of the CPU usage activity (when it goes unusually high) and observe any suspicious activity at the endpoints. Any threat, similar to the likes of Golang, can be avoided by vigilante inspections and immediate responses. Awareness about crypto mining threats is also a must.

Windows 10 New Feature Hunts and Thwarts PUAs/PUPs


Per reports, Microsoft has hinted that the next main version of Windows 10 will come stacked with a fresh security feature that would allow the users to facilitate the Windows Defender’s secret feature that helps hunt and bar the installation of known PUAs (Potentially Unwanted Applications).

PUA’s are also widely known as PUPs that stands for Potentially Unwanted Programs. These aren’t as well known by the users in the cyber-crime world as all the other major threats but are a valid threat nevertheless.

Per sources, these are software that is installed on devices via fooling the targets. The term for which the PUP/PUA stands is self-explanatory with regards to applications or programs that your device may not really need.

PUPs/PUAs go around with tactics like either by employing “silent installs” to dodge user permissions or by “bundling” an unrequired application with the installer of an authentic program.

Sources mention that PUAs most commonly contain applications that alter browser history, hinder security controls, install root certificates, track users and sell their data, and display invasive ads.

As per reports, the May 2020 update is to be rolled out to the users in the last week of this month. Microsoft mentioned that it has added a fresh new feature in its setting panel that would allow users to bar the installation of any unwanted applications or programs in the form of known PUAs/PUPs.

As it turns out, researchers mention that the feature has been available in the Windows Defender for quite a lot of time, but for it to kick start it would need group policies and not the usual Windows user interface.

As per sources, to enable the feature a user must go to ‘Start’, ‘Settings’, ‘Update & Security’, ‘Windows Security’, ‘App & Browser Control’, and finally 'Reputation-based Protection Settings’. Once updated, the feature would show two settings, the above-mentioned feature is disabled by default and would need to be enabled manually. However, Microsoft suggests, enabling both the settings.

Reports mention, that the “Block Apps” feature will scan for PUAs that have already been downloaded or installed, so if the user’s using a different browser Windows Security would intercept it after it’s downloaded. However, the “Block Downloads” feature hunts the PUAs while they are being downloaded.

Windows 10 Users Beware! Astaroth Malware Campaign is Back and More Malicious!


A malware group that goes by the name of ‘Astaroth’ has re-emerged stronger and stealthier than before. This group has been known for exploiting Microsoft Windows tools to further the attack.

Microsoft had gotten aware of these methods and exposed the malware group and its “living-off-the-land” tactics. But the malware resurfaced with a hike in activity and better techniques.

Reportedly, the Windows Management Instrumentation Command-line (WMIC) is the built-in tool that got used the last time as was spotted by the Windows Defender ATP.

Per sources, the analysis done by Microsoft led to the discovery of a spam operation that spread emails with links to websites hosting a “.LNK” shortcut file which would instruct the WMIC and other Windows tools to run “fileless” malware in the memory well out of the reach of the anti-malware.

Sources indicate that having learnt from mistakes, Astaroth now entirely dodges the use of the WMIC. January and February showed a rise in activity.

According to sources, the new styled campaign still commences with a spam email comprising of a malicious website hosting link, LNK file but it the new version it employs a file attribute, “Alternate Data Streams” (ADS), that lets the attacker clip data to a file that already exists so that hiding malicious payloads gets easier.

Per source reports, the first step of the campaign which is a spam email reads, “Please find in the link below the STATEMENT #56704/2019 AND LEGAL DECISION, for due purposes”. The link is an archive file marked as, “Arquivo_PDF_.zip”.

It manipulates the ExtExport.exe to load the payload which per researchers is a valid process and an extremely unusual attack mechanism.

Once the victim clicks on the LNK file with the .zip file in it, the malware runs an obfuscated BAT command line, which releases a JavaScript file into the ‘Pictures’ folder and commands the explorer.exe that helps run the file.

Researchers mention and sources confirm that using the ADS permits the stream data to stay unidentifiable in the File Explorer, in this version Astaroth reads and decrypts plugins from ADS streams in desktop.ini that let Astaroth to rob email and browser passwords. It also unarms security software.

Per sources, the plugins are the “NirSoft WebBrowserPassView” tool is for regaining passwords and browsers and the “NirSoft MailPassView” tool is for getting back the email client passwords.

This is not the only legitimate tool Astaroth exploits. A command-line tool that goes by the name of “BITSAdmin” which aids admins to create download and upload jobs with tracking their progress is exploited to download encrypted payloads.

Reportedly, Astaroth has previously wreaked havoc on continents like Asia, North America, and Europe.

HACKED- Windows 10, macOS, Adobe, VMware, Apple and Oracle at The Pwn2Own 2020!


Pwn2Own is a well-known computer hacking contest which is held once every year at the CanSecWest security conference. In this contest, the contestants are tested on how well they could exploit commonly used software and mobile devices with formerly unheard of vulnerabilities.

An issue as grave as the Coronavirus pandemic has clearly not affected the spirits of the Pwn2Own 2020 hacking competition which got done with its first two days.

On Day 1, security researchers and participants bagged a handsome amount of over $180,000 for exploiting the Windows 10, Ubuntu Desktop and macOS, mention sources.

Reportedly, a “team from the Georgia Tech Systems Software and Security Lab succeeded in exploiting a kernel privilege escalation to execute code on macOS” by way of Safari. The attack mechanism that ended up winning for the team $70,000 was comprised of 6 vulnerabilities.

Per the event page (thezdi.com), Georgia Tech employed a “6 bug chain to pop calc and escalate to root”.

The team that has won several preceding editions of the hacking contest, Team Fluoroacetate, won themselves a victorious $40,000 after they employed a “local privilege escalation exploit” meant for the Windows 10.

Reports mention that one of the two members of the aforementioned team also won himself a smashing amount of $40,000 for yet another privilege escalation exploit pursuing Windows 10.

As per sources, the RedRocket CTF team got themselves a win, owing to it to one of their members, Mafred Paul, who bagged an attractive amount of $30,000 for a local privilege escalation exploit focused on Ubuntu Desktop. The hack was about the manipulation of the ‘Input validation bug’.

On Day 2, The Fluoroacetate successfully targeted the Adobe Reader with a local privilege escalation by employing a pair of UAFs, mentioned sources and grabbed an amount of $50,000.

Per reports, the Synacktiv team targeted the VMware Workstation but unfortunately to no avail in the given duration of time. There also were special demonstrations of the Zero Day Initiative against the Oracle VirtualBox.

This was the very first time the organizers allowed “conditional remote participation” in the Pwn2Own hacking contest, understandably because of the increased concerns of people about traveling due to the Coronavirus outbreak.



Windows 10 Users Beware! TrickBots' Prevalence And Conveyance Escalates in Devices



Reports mention that recently attackers were found exploiting the latest version of the “Remote Desktop ActiveX” which was developed for Windows 10.

Sources say that similar to what many others are doing, the exploitation could cause the automatic execution of the “OSTAP” JavaScript downloaded on the ta
rget’s systems.

Per analyses of researchers, the ActiveX is employed to automatically execute a mal macro right after the target enables a document. The majority of the documents contained images to encourage people to enable the content.

Per reports, the catch was that the image contained a hidden ActiveX control below it; the OSTAP downloader was disguised in white text to make it seemingly invisible to eyes and readable for machines.

Trickbot attackers misuse people’s tendencies of not updating their software with the latest updates to protect the systems.

Trickbots happen to be among the most advanced versions of the malware structures. The number is increasing and so is the threat to systems with Windows 10. Not of late, researchers dug out more documents that execute the OSTAP JavaScript downloader.

It was also found out that the groups of tricksters that were exploiting the ActiveX control were not the only ones. Other groups were also into misusing them along with a few others.

According to sources, the victim documents had the following nomenclature-“i<7-9 arbitrary="" digits="">.doc”. Almost every document had in it an image that would convince the enablers to open it. What the opener wouldn’t know is that below the image is a hidden ActiveX control. The OSTAP JavaScript downloader would be disguised as white text which only the machines could read.

Per sources, the analysis of the ActiveX code exposed the use of the “MsRdpClient10NotSafeForScripting” class. The script is crafted in a way that the server field is left empty to cause an error which would aid the attackers further on.

According to researchers, the technique that kicks the ‘macro’ on is, “_OnDisconnected”. This will execute the main function, first. It doesn’t get executed instantly for it takes time to resolve the DNS to an empty string only to return an error.

The OSTAP’s execution would depend on the “error number matches” exactly to “disconnectReasonDNSLookupFailed”. The OSTAP wscript directive is relative to the error number computation.

The execution of the wscript would work with its very content. This trick is quite an old one in the book. Microsoft’s BAT would ignore the ‘comments’, along with the content and everything that comes with the syntax, while the execution’s happening.

Once the JavaScript is edited per the attackers’ needs, the obfuscation scheme gets repeated. Updating systems doesn’t work every time but it’s a pre-requisite anyway.

A defense mechanism is paramount in cases of OSTAP and the likes of it. With the technology that’s prospering with every passing minute, so is the number of attack mechanisms and attackers. Hence keep systems updates and a tight security structure in place.


Modified TrickBot Trojan can now Steal Windows Active Directory Credentials


TrickBot trojan, a strain of malware that has been around affecting users since 2016 - is now evolved to steal Windows Active Directory credentials. Today, in the cybersecurity ecosystem it is considered as one of the top threats abusing businesses, experts estimate that TrickBot is responsible for compromising more than 250 million email accounts till date. Earlier, TrickBot went a step further while targeting Windows 10 users by disabling Windows defender onto their systems rather than just bypassing the protection. Fundamentally, TrickBot is a banking Trojan and is generally deployed through spearphishing emails like invoices mailed to the accounts department. Typically, it is attached as infected Microsoft Excel or Word documents. The malware can be spread across an organization in a number of ways, one of them is via exploiting vulnerabilities in a protocol called SMB which makes the process of sharing and accessing files on other systems easy for Windows computers.

First identified by Sandor Nemes, a security researcher from Virus Total, this new module of TrickBot dubbed as "ADII" further amplifies the threat it possesses for security, it steals Windows Active Directory information by executing a set of commands.

An Active Directory database is being created and stored into the default C:\Windows\NTDS folder on the domain controller, a server here is acting as the domain controller. Now, all the information including passwords, computers, users, and groups of Windows Active Directory are saved in a file by the name "ntds.dit" in the database. As all the aforementioned information is sensitive in nature, Windows resort to a BootKey that is located in the system component of the Registry and encrypts the information with the help of it. Admins who are responsible for database maintenance use a special tool known as "ntdsutil" to work with that database. Reportedly, standard file operations cannot access the BootKey.

How TrickBot Goes About Stealing Active Directory Credentials?


Administrators use the command "install from media", also known as "ifm", to create a dump of Active Directory. The command leads to the creation of an installation media for setting up new Domain Controllers. The new module "ADII" exploits the ifm command to produce a copy of the Windows Active Directory database; after the database is dumped into the %Temp% folder, the bot collects the information and transfers it to the admin. The collected data can be effective in infecting more systems in the same network and could also be employed by various other malware in search of similar vulnerabilities.

Microsoft Enters 2020 with Two New Products


Microsoft plans to come up with two products with the advent of the New Year, Windows 10X-powered Surface Neo and Android-powered Surface Duo and this could be an indication of 2020 being the year of foldable and dual-screen devices from smartphone and PC creators.

Microsoft's new operating system, Windows 10 X, is set to power the main rush a.k.a the first wave of foldable and dual-screen equipment scheduled for holiday 2020 and Surface Neo is said to have been the primary equipment to be dispatched with Windows 10 X, however, the Redmond giant is additionally preparing the OS for dual-screen PCs from accomplices.

Windows 10 X is additionally expected to power the dual-screen PCs created by Microsoft OEM accomplices like HP, Dell, and Lenovo. A leak as of late affirmed that Windows 10 X will be coming to workstations and other customary PC form factors in the future, however apparently the operating system is as yet 'immature'.


Anyway because of the moderate-paced advancement of the operating system and inadequate adaptable panel supply as per another report, Intel probably won't promote foldable notebooks in the future.

Despite the fact that Intel's dual-screen model highlights a 17-inch display and it would run Windows 10 X, the company will postpone the unveiling which was initially planned for CES 2020 because of issues with “immature OS support”.

The report refers to 'upstream supply chain' as the source of the talk likewise including that Intel won't promote foldable notebooks until mid-2020.

Windows 10 X was announced at the October 2019 occasion and Microsoft has ever since protected it under much 'secrecy' and still hasn't uncovered when it intends to launch Windows 10 X, yet the operating system is reputed to finalize at some point in 2020, a couple of months or weeks before the launch of Surface Neo and other much-awaited foldable devices.

A new zero-day Exploit Leaked to Bypass Already Patched Vulnerability (CVE-2019-0841)



An exploit broker and hacker, SanboxEscaper made a comeback and published the details about a new zero-day which affects the already patched local privilege escalation vulnerability, CVE-2019-0841 on Windows 10 and Windows 9 operating server.

The details of the zero-day have been published on GitHub and the account and repository from which the details were leaked are the same as the ones which attributed to the leaks of 8 other previously released zero-days. 

SandboxEscaper have been actively involved in leaking zero-day exploits since August 2018, some of the previously leaked zero-days are listed below:

LPE in Advanced Local Procedure Call (ALPC)
LPE in Microsoft Data Sharing (dssvc.dll)
LPE in the Windows Error Reporting (WER) system
LPE exploit in the Windows Task Scheduler process
Sandbox escape for Internet Explorer 11
Bypass of the CVE-2019-0841 protections
LPE targeting the Windows Installer folder

The hacker who recently exploited CVE-2019-0841 vulnerability which was patched by Microsoft in April can further install malicious programs, edit and delete data. The vulnerability can be executed by deleting all files, folders, and subfolders in the Edge Browser.

Commenting on the matter, Will Dormann, Vulnerability Analyst at the CERT/CC, says, “I’ve confirmed that this works on a fully-patched (latest May updates) Windows 10 (1809 and 1903) system. This exploit allows a normal desktop user to gain full control of a protected file.”

“Make sure you have multiple cores in your VM (not multiple processors, multiple \b cores\b0 ).\par. It’s going to increase the thread priority to increase our odds of winning the race condition that this exploits”

Basically, it requires the attacker to log in as a local user and then execute this exploit which triggers the vulnerability, which then allows the attacker to access and change system permissions and gain full control of the system making him act as the admin.
