Hive ransomware has been targeting Microsoft exchange servers lately vulnerable to ProxyShell security issues in order to deploy various backdoors. Once the backdoor has been placed various attacks can be performed including but not limited to network reconnaissance, stealing admin accounts, taking valuable data, and even installing and deploying file-encrypting algorithms.

ProxyShell is a set of three vulnerabilities in the Microsoft Exchange Server that allows remote code execution without authentication on vulnerable deployments. The flaw has been used in past by various ransomware like Conti, BlackByte, Babuk, Cuba, and LockFile.
Security vulnerabilities have been reported to be fully patched on May 2021 but how Hive was able to still be successful in exploiting PowerShell and infiltrating into the system there seems to be still some unpatched and open issues.
Hive has gone a long way since it was first observed in the wild back in June 2021, having a successful start that prompted the FBI to release a dedicated report on its tactics and indicators of compromise.
In October 2021, the Hive gang added Linux and FreeBSD variants, and in December it became one of the most active ransomware operations in attack frequency.
Last month, researchers at Sentinel Labs reported on a new payload-hiding obfuscation method employed by Hive, which indicates active development.

Choosing default browser in settings“Installing, this may take a few minutes… WslRegisterDistribution failed with error: 0x8007019e/0x8000000d Error: 0x8007019e/0x8000000d The parameter is incorrect. Press any key to continue.”Error code 0x8007019e or 0x8000000d could be due to the absence of supporting Windows 10 features since the error does not even let one use the WSL-based command line. If you are one of the users facing this problem, then you’ve come to the right place as this post will provide you with a couple of suggestions to fix it. There are two options you can check out to fix the problem, but before you do that, you need to make sure that the Windows Subsystem for Linux feature is enabled. The two options include enabling WSL using the “Turn Windows features on or off” option and using the Windows PowerShell.
Following are proven solutions that will resolve the issue and provide you with a working device.
You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.
The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.
This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.
These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.
There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.
So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.
There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.
On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.
If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.
“The drive is not a valid backup location.”One of the causes of this problem is that Windows was not able to recognize the USB drives as a valid backup location since USB storage devices weren’t previously large enough to store system images. To fix this error, here are some possible solutions that might help.
CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.
Error code 0xc004f210 is one of the many activation errors that affect Windows 10 users. Users will be able to identify error code 0xc004f210 because of the following common symptoms which occur:
Error CausesError code 0xc004f210 usually occurs due to issues related to one’s product key or digital entitlement. Both the product key and digital entitlement are used by Microsoft to enable customers to activate the version of Microsoft that they have legitimate access to. If you enter the wrong product key or if you upgrade to Windows 10 but the current version of Windows to which you are attempting an activation does not match the edition of your digital entitlement, error code 0xc004f210 may occur. To correct this issue, you will need to implement one or more manual repair procedures. This will depend on the problem that caused the error to occur in the first place.
The methods below are simple procedures that Windows users lacking technical knowledge will be able to successfully complete. However, do contact a Windows repair technician if you have difficulty completing the manual repair methods listed below, or if the problem persists after completing these steps.
In order to successfully activate your Windows 10 operating system and resolve error code 0xc004f210, you will need to enter a valid product key. Ensure you enter the 25-character code in the order it is given as making a simple mistake while typing the product key can lead to the reoccurrence of the error code. Follow the instructions below to enter the product key.
You should be able to successfully activate Windows 10 once you complete the process. However, move to the next manual method suggested below if the problem persists as error code 0xc004f210 could be due to an issue with your digital entitlement.
Digital entitlement, a new form of activation that doesn’t require the use of a product key, could be the real reason you are experiencing error code 0xc004f210 on your device. To combat any issues related to your digital entitlement, ensure the version of Windows 10 installed on your system matches your digital entitlement. This will require that you reinstall your operating system as well. After reinstalling Windows 10, follow the steps below to complete the process.
If this method is successful, you will no longer see the error code 0xc004f210 pop up on your screen. However, contact a Windows repair technician to evaluate your system if the issue persists.
This method involves the use of a powerful automated tool. But why is this important you might ask? A third-party tool is often the best solution when all manual repair efforts fail. Automated tools come equipped to tackle the most serious PC problems including error codes which can cause frustration and result in reduces PC performance.
So, what is Electron bot, and why it even matters if it is in the MS store. Electron bot is malware that somehow found its way inside MS Store via game clones of popular games temple run and subway surfer. This infiltration led to the infection of around 5000 systems over the globe in a very short period of time.

This malware is a backdoor that gives complete system control to the attacker. Any type of execution can be performed remotely in real-time. Usually, this kind of attack was aimed at a spread of click fraud over popular social media like Facebook, google, youtube, etc.
Electron Bot's primary goals in the ongoing campaign analyzed by researchers are:
These functions are offered as services to those who want to increase their online profits illegitimately, so the gains for the malware operators are indirect.
For now, users may take note of the publishers who released confirmed malicious game apps using the following names:
