This vulnerability has affected both Windows XP as Windows 10, and to all operating systems in between. The problem lies in the way in which MSCTF it establishes communications, allowing even an application running in an isolated or low-privilege environment to read and write data to an application with more privileges.
MSCTF is a module present in the Text Services Framework (TSF) Windows that manages elements such as the processing of what we type with the keyboard, key distribution or voice recognition. Therefore, this element is executed each time we connect to our user. If we go into the task manager, we will see the CTF Loader process running, and it is responsible for communicating the changes made to the keyboard layout or input methods to the rest of the applications.
This interaction is forced into applications by the kernel, but the problem is that there is no access control or verification for this interaction. Any application or user can connect to a CTF session, read and write text in any window. any session, falsify the identifier of an application, increase the privileges or take the identity of a CTF service.
So, it's as simple as waiting for a administrator Sign in to take control of your session and read sensitive information from other apps, including Passwords, get System permissions, delete the UAC dialog box, or execute commands in the Administrator Console. And all this in Windows 10 fully corrected.
The investigator who discovered the incident reported his discovery to Microsoft in mid-May. After 90 days, he decided to publish the information because Microsoft has not fixed the bug yet in one of its operating systems. In addition, it took more than a month for the company to respond to the investigator she was going to investigate. Two weeks before its release, Microsoft was still asking for details about the exploit.
Let's hope now that the vulnerability is public Microsoft hurry to fix itbecause, at the moment, all Windows computers are vulnerable to a failure of the provisioning function. For the moment, Microsoft has corrected one of them, CVE-2019-1162, this month, but for the rest, they said they would need more time.
This week, Microsoft has released updates that affect the collection side of telemetry of its old operating systems, and which some users see the network.
The post office Microsoft includes a telemetry update in the security patches, raising fears about the company's motives appeared first on ExtremeTech.
The Office 365 Advanced Protection Team discovered files in ACE format that were trying to take advantage of the WinRAR vulnerability becausehundreds of millions of computers on which the latest version is not installed which fixes the failure (you can also manually delete the DLL to protect yourself).
The vulnerability, CVE-2018-20250, is increasingly used by cybercriminals around the world since its discovery. This vulnerability allows you to locate a file containing malware anywhere on a Windows computer; including in the File of welcome so that it runs whenever the computer is turned on.
One of the groups that uses it and was detected by Rex Plantado of the Office 365 ATP research team is: MuddyWater. It is known that this group has existed since 2017 and that it attacks people in the Middle East, Europe and the United States. To carry out attacks, they generally modify the files sent by phishing emails posing as companies and security agencies of different governments.
The e-mail they detected came under the name of the Ministry of Foreign Affairs of Afghanistan and had very specific objectives related to: telecommunications and satellite card service. The e-mail contained a Word file with a link to another document stored in OneDrive. If clicked, a second Word file was downloaded in turn with a malicious macro that, in the event that the user would have ignored the security warnings, would have been infected subsequently.
The macro in turn also performs a PowerShell Script who collects information on the infected computer, assigns him a Unique ID, and send it to a remote server. This script is also used to exploit the WinRAR vulnerability Download an ACE file with three JPEG photosand place a malicious file called Dropbox.exe in the home folder when you try to decompress.
From there, the malware informs the user that he has to restart the computer because a DLL is missing. Indeed, the vulnerability allows you to place a file in any folder, but can not run it. Therefore, when restarting the PC and after placing the file in the startup folder, the Malware runs at each startup.
Once the PC is restarted, the attacker persistently maintains a backdoor via PowerShell allowing him to take full control of his computer and install it. even more powerful malware; and all at a distance. The script is not even written in the hard disk or SSDbut it stays in memory to make it even harder to detect.
IP you mean "Internet Protocol"or "Internet Protocol", and the IP address is an identifier. This is a number assigned by the network that identifies the connected devices. However, there are two types of IP addresses: public and private. And not only are they not identical, but they also have a different function compared to each other.
The private IP address is the one assigned to a device, actually, privately. That is, the one that is assigned in a private network portion of the access gate which, in general, will be the router. For there to be no conflict in internal communications, each smartphone, video game console, TV and other devices have a different private IP address corresponding to a range depending on the class.
The different classes of private IP addresses establish the possible range that can be assigned to networked devices. Class A is used for large international companies, while Class B private IP addresses are for medium-sized enterprises and Class C are those we will find regularly for home networks and small by the amount of connected devices. Thus, the usual usage is that home users have the default 192.168.1.1 IP address configured for the router and the 192.168.1.x private IP addresses for the rest of the devices connected to the LAN.
The public IP address is the one that the ISP –the telecommunications operator, usually Assign a customer. It is used to identify devices or complete networks on the Internet and, in general, these are dynamic IP addresses. The client devices, computers and smartphones and others used for browsing the Internet, are identified on the network by a public IP address. But they also identify in this way, and with a static public IP address, the servers in which the web pages and services are hosted.
In the case of Web servers, there is a dependency on DNS servers. To load a web portal, the user types a URL into the web browser. In doing so, the Web server makes a request to the DNS servers, which resolve the domain name by "discovering" the associated IP address, then load the corresponding directory to display the web content. This public IP address is generally unknown to the user, but is registered by the DNS servers that perform the domain name resolution.
The IP adress public, by its very nature, can be recognized externally. Therefore, to know the public IP address of a device –as long as it's your own-, the best is to use an online service. For this we can use what is my IP address. We simply need to access and, without doing anything else, we will find at the bottom of the information we are seeking. The public IP address that identifies the device on the Internet, the Internet Service Provider (ISP) and the company name, as well as the approximate location of the IP address and, therefore, the peripheral.
The ISP is responsible for assigning IP addresses. and this can be done statically or dynamically. In other words, you can assign a different IP address for each connection or a fixed address for all connections made. When dynamically assigning IP addresses, this is done in accordance with DHCP. The reason for the dynamic attribution of IP addresses is related to the scarcity of identifiers on the network; In general, static IP addresses are paid and used exclusively for recurring external connections.
In other words, dynamic IP addresses are assigned to default users and clients, while fixed or fixed IP addresses are usually assigned to data servers, messaging services, and so on. Obviously, privacy is increasingly neglected when a static IP address is used. However, this simplifies the configuration of recurring external connections and, if necessary, the work of DNS servers for resolving domain names, whatever the time needed to update their databases, which can go up to 48 hours
If you are using a computer with a Windows operating system, you can change the IP address of your device from the command console, provided you are using DHCP:dynamic IP address in the local network. To do this, you will need to use the Windows + R keyboard shortcut to access Start and then All Programs. In the search bar, enter cmd for it to appear System symbol and right-click on Run as administrator.
Once here, you can enter the order ipconfig and see the assigned IP address at this time; then we can enter the order ipconfig / release which allows to leave this free IP address and, lastly, the command ipconfig / renew to contact the gateway to request a new IP address according to DHCP. Finally, we can re-enter the same command from the beginning to find out which IP address was assigned to us on this occasion.
If we use a fixed IP address on the local network or if we want to do so, we will need to access the search field from the taskbar, enter the Control Panel and open Networks and Internet. From there, in the network connections, you will find the configured network card, which you must right-click to open Properties. Then we will have to locate Procoolo from Internet version 4 (TCP / IPv4) and open it with a double click. Then we will select & # 39; Use the following IP address & # 39;, and here we can configure it manually.
On Android mobile devices, the IP address changes based on DHCP each time we connect and disconnect from the wireless network. Therefore, the only possible configuration is a fixed IP address. If we need this type of configuration, we should open Settings and, in the Wireless Wi-Fi Connectivity section, you should see the list of available networks. We must locate ours, of course, select it and, when connecting, when requesting the security password, we should click on Advanced options to select the IP parameters then Static IP
On the iPhone, as on Android mobile devices, the dynamic IP address is changed with each new wireless LAN connection. But we can also select a fixed IP address configuration. To do this, we will have to open the settings, access Wi-Fi and click on the "i" icon next to the network we are going to connect to. In the IPv4 Address section, we will click Configure IP to select "Manual", and we will be able to make network adjustments manually.
Rufus is a popular and very comfortable tool to make a USB memory is bootable and we can install Windows on our PC if no operating system is installed and without having to resort to the DVD as before. With this program, the process is as simple as starting it, selecting the ISO that we downloaded to the PC, connecting the USB memory and putting it back to Start. In addition, it allows us to choose if we want to use GPT or MBR as a partition scheme. In addition, the program is portable, so that it does not require installation.
Now Rufus 3.5 adds an extra feature, where in the second box this will allow us to select the route where we uploaded the ISO image, or even to allow us choose to download If we choose the download option, the program downloads a PowerShell Script which shows all available ISO images. This script, called Fide, is also available outside the program on its own page. GitHub.
Rufus only supports the official versions provided by Microsoft and can choose the version that suits us best. In the case of Windows 10, we find all versions of the operating system versions, including the latest update 17763.107 of October 2018. With the media authoring tool, it does not exist. There is no way to know which version we are downloading, although it usually is the most recent one.
After choosing the version we want, we can also choose between the version of the operating system we want to download, choose between Windows 10 Home, Pro or Education. In the case of Windows 8.1, you can choose the normal version or you can use Professional, in addition to the N versions. Finally, you choose the language in which you want to install the operating system and indicate if you want to use the version of . 32 or 64 bits, and we have already passed the copy of the ISO executable to the USB key.
The version of Rufus 3.5 is currently in betaand may present problems for some users. The only thing that could be missing is that it was also allowed to do it with the Windows 7 ISO, although, knowing that there is only 10 months of official security support, it is better look to the future and install newer versions. If you do not like Windows 10, 8.1 at least, you will have security updates until January 10, 2023.
You can download Rufus 3.5 on their page GitHub.
