The attackers also appear to have leveraged another commercial IT management tool known as PDQ Deploy to push out Windows batch scripts to machines they planned to target. Sophos Rapid Response has created a chart that highlights the consequences of one of these batch files running. The batch files are run before the computer is rebooted into Safe Mode.
These batch scripts orchestrate stages of the attacks and lay the groundwork for the final phase in which the threat actors deploy the Avos Locker ransomware. One of the batch scripts we recovered was called Love.bat (shown above), which was pushed out to machines on the network by the PDQDeployRunner service. We also saw batch files named update.bat or lock.bat with small variations in them.
Disable any Antivirus using batch script

These orchestration scripts modified or deleted Registry keys that effectively sabotaged the services or processes belonging to specific endpoint security tools, including the built-in Windows Defender and third party software from companies such as Kaspersky, Carbon Black, Trend Micro, Symantec, Bitdefender, and Cylance. The script disables Windows Update and attempts to disable Sophos services, but the tamper protection feature prevents the batch script from succeeding.
It is not so easy to reliably and totally disable the Windows Defender. There is a PowerShell script that uninstalls Windows Defender, but you may not be able later to install it back. This script requires two reboots.
I've worked for days to achieve this, looking at almost any work done on Internet including the posts here. I did not find any way to do it without using third-party dependencies. So I wrote a script for it instead.
I cannot copy it here due to character limitation, it's around 1000 lines batch script with some PowerShell calls. It's totally reversible to Windows defaults, but you need to run revert script twice.
Windows Defender is an all in one security software from Microsoft consisting of antivirus and a firewall. Windows Defender comes pre-installed with Windows 10. It gets all its updates from Windows Update.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[300,250],'itechtics_com-medrectangle-4','ezslot_6',149,'0','0']);__ez_fad_position('div-gpt-ad-itechtics_com-medrectangle-4-0');Although you can turn Windows Defender on or off from Windows Settings, there are other quick ways to turn it on or turn off Windows Defender Windows 10 or even Windows 8/8.1. You should choose the best method according to the version of Windows you are using.
Please note that this is a temporary method to stop Windows Defender. The service will return to its original state once the system is restarted.To disable Windows Defender permanently using the command prompt, run the following command:sc config WinDefend start= disabledsc stop WinDefendTo enable it again on startup, run the following commands:
This will only turn off the firewall. The antivirus and other functionality of Windows Defender will keep on working.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[468,60],'itechtics_com-mobile-leaderboard-2','ezslot_22',165,'0','0']);__ez_fad_position('div-gpt-ad-itechtics_com-mobile-leaderboard-2-0');How to turn off Windows Defender real-time antivirus onlyIf you want to turn off the antivirus real-time functionality only, you can follow the steps below:Open Windows Settings (Windows key + i)Click on Update & Security and then Windows SecurityFrom the left-hand pane, click on Virus & threat protectionIn the right-hand pane, toggle real-time protection to off.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[250,250],'itechtics_com-narrow-sky-2','ezslot_24',607,'0','0']);__ez_fad_position('div-gpt-ad-itechtics_com-narrow-sky-2-0');VerdictIf you have not installed any third-party antivirus, then you should keep Windows Defender running as it will protect you from the most common virus/hacking threats while you are connected to the Internet. There should always be an anti-malware solution running on your computer at all times. These methods should be used to disable the security software temporarily.I hope this has been informative for you. If there are any other easier ways to enable or disable Windows Defender, please let us know in the comments below!Also see:
When you need to disable the firewall on many computers, it would be inefficient to manually login to each computer and run the commands. Especially in a network environment, you could disable remotely using PowerShell.
The above process is good only if you are working on a few remote computers. But, if you have a bulk of computers where you need to disable it, you will need an approach that is more adapted to scripting. For that, you can use the Invoke-Command cmdlet.
There surely are many different ways to disable Windows Firewall. Some of those methods were covered in this article. However, there are still other methods that you could explore on your own, such as using PsExec to remotely disable it.
In one instance, the VBS downloaded a batch script which connected to a Cobalt Strike C2 via a DLL beacon dropped on the device by PowerShell. It was launched via rundll32.exe, with the known Cobalt Strike flag StartW. Reconnaissance queries were then run on domain-joined devices, performing actions such as searching for all domain trusts on the network.
Historical observation of typical DEV-0569 attack begins with malicious links delivered to targets via malicious ads, fake forum pages, blog comments, or through phishing emails. These links lead to malicious files signed by the attacker using a legitimate certificate. The malicious files, which are malware downloaders known as BATLOADER, pose as installers or updates for legitimate applications like Microsoft Teams or Zoom. When launched, BATLOADER uses MSI Custom Actions to launch malicious PowerShell activity or run batch scripts to aid in disabling security solutions and lead to the delivery of various encrypted malware payloads that is decrypted and launched with PowerShell commands.
DEV-0569 has used varied infection chains using PowerShell and batch scripts that ultimately led to the download of malware payloads like information stealers or a legitimate remote management tool used for persistence on the network. The management tool can also be an access point for the staging and spread of ransomware.
By using Batch File you can create an extremely dangerous virus which can delete the Windows files, format different drives [C:\, E:], steal data files and information, disable antivirus, firewall, etc.
how do you make something like this that will run multiple batch files and a vbs? I have token a lot of batch viruses and made a fake error, and I want to run them all at a certain pace of 2 minutes in between each payload. How do I do this? is there a way to make it into a batch file that will run each thing from a download and/or usb drive depending whitch one it is in with a 2 minute time space in between each payload? if so can you give me the script?
It's also possible to change the configuration of the workflow through workflow variables. If a variable is defined for a workflow, you can use it in batch mode by referring to it using a comma separated triplet to specify the name, value and type like this:
This particular command requires us to run as an administrator due to the face that it is a system command. This will always be the case when running your batch script. Now, we are going to need the name(s) of the network adapters that we will be disabling and re-enabling in our command. Type in the following in Command Prompt:
A batch file (also known as a .bat file or batch script) is a text file that the Windows cmd.exe command line processor executes as a batch job. Command Prompt assumes both the role of interpreter and runtime environment. Put simply, a batch file is a computer program or script containing data or tasks that are processed sequentially by Command Prompt.
In 2006, Microsoft released PowerShell, another framework that allows you to program and execute batch files. It was made open-source and cross-platform in 2016 and uses the MIT license. PowerShell provides an alternative command line interpreter and its own scripting language called PowerShell Scripting Language.
To save these batch instructions or the script, click File and choose Save As... Specify the save location and enter a name for the script with the extension .bat in the File Name field:
After you create and save the batch file, you have two options to run it: Either run the script in the familiar Windows Explorer environment or open Command Prompt and run it using a command-line command.
You can customize a batch script at any time, for example if you want to add or remove commands or modify directories. To do this, simply go to the folder containing the command line script and right-click it. Then choose Edit:
Although you can manage the feature through the Settings app, you can also enable or disable Remote Desktop on Windows 10 using commands with Command Prompt or PowerShell. You may want to use this method to create a script to configure Remote Desktop on multiple computers more quickly. Or you can send the script to a user, allowing them to automatically set up the feature without additional steps. 2ff7e9595c
