Aircrack-ng, penetration test
Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools.

Aircrack-ng 1.6 - (C) 2006-2020 Thomas d'Otreppe
https://www.aircrack-ng.org
usage: aircrack-ng [options]
Common options:
-a : force attack mode (1/WEP, 2/WPA-PSK)
-e : target selection: network identifier
-b : target selection: access point's MAC
-p : # of CPU to use (default: all CPUs)
-q : enable quiet mode (no status output)
-C : merge the given APs to a virtual one
-l : write key to file. Overwrites file.
Static WEP cracking options:
-c : search alpha-numeric characters only
-t : search binary coded decimal chr only
-h : search the numeric key for Fritz!BOX
-d : use masking of the key (A1:XX:CF:YY)
-m : MAC address to filter usable packets
-n : WEP key length : 64/128/152/256/512
-i : WEP key index (1 to 4), default: any
-f : bruteforce fudge factor, default: 2
-k : disable one attack method (1 to 17)
-x or -x0 : disable bruteforce for last keybytes
-x1 : last keybyte bruteforcing (default)
-x2 : enable last 2 keybytes bruteforcing
-X : disable bruteforce multithreading
-y : experimental single bruteforce mode
-K : use only old KoreK attacks (pre-PTW)
-s : show the key in ASCII while cracking
-M : specify maximum number of IVs to use
-D : WEP decloak, skips broken keystreams
-P : PTW debug: 1: disable Klein, 2: PTW

-V : run in visual inspection mode
WEP and WPA-PSK cracking options:

-j : create Hashcat v3.6+ file (HCCAPX)
-J : create Hashcat file (HCCAP)
-S : WPA cracking speed test
-Z : WPA cracking speed test length of
execution.
-r : path to airolib-ng database
(Cannot be used with -w)

How to Disable Welcome message to group Office 365 online
How to Disable Welcome message to group Office 365 online(Azure Directory)?
Solution 1:
Using PowerShell
Step 1 Open PowerSheel and connect to ExchangeOnline
PS C:\Users\UKgoodByeSales> Connect-ExchangeOnline
Step 2 Change the value of this UnifiedGroupWelcomeMessageEnable to “false”
PS C:\Users\UKgoodByeSales> Set-UnifiedGroup -Identity "UKgoodbyeSalesDepartment@groups.ukgoodbye.co.uk" -UnifiedGroupWelcomeMessageEnable:$false
Use the command Get-UnifiedGroup view the variable of the Sharepoint group or Azure D group:
C:\Users\MoussaSow> Get-UnifiedGroup -Identity "UKgoodbyeSalesDepartment@groups.ukgoodbye.co.uk" | Format-List
Solution Microsoft Power apps and power automate error appres://blobmanager
Solution for Microsoft Power apps and power automate error appres://blobmanager, that will upload corruputed file to Sharepoint:
Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '12861': 'The template language function 'dataUriToBinary' expects its parameter to be formatted as a valid data URI.

Change this by:
PowerAppsUploadDocuments.Run(AddMediaButton1.FileName,UploadedImage1.Image);
This using json:

Solution 1: Rebsumit it
If the error code 500 or 502 appears, the failure is temporary or transient. Click or tap Resubmit to try the flow again.
Solution 2: Double-check the original PDF you are try to appaend is OK first.
You can not preview the file SharePoint by the browser the “Insert HTML to PDF” process will fail.
Hmm.. Looks like this file doesn’t have a preview we can show you.
In our case the uploading document by Power apps were not decoding the final document on SharePoint
Share an app with Microsoft 365 Groups
Share an app with Microsoft 365 Groups. Ppower apps how give implicit access to sharepoint group?
Ensure you have access to the Azure AD cmdlets.
Go to Azure portal > Azure Active Directory > Groups > Select the appropriate group > Copy the Object Id.
1 Connect to Azure AD using PowerShell:
code> C:\system>system32> Connect-AzureAD
2- Get-AzureADGroup -ObjectId 9d046f003-93b7-4691-9935-174139c990d3 | select *
3 If the group isn’t security enabled, you can enable it using PowerShell cmdlet Set-AzureADGroup by setting the SecurityEnabled property to True:
code> C:\system>system32>Set-AzureADGroup -ObjectId 9d046f003-93b7-4691-9935-174139c990d3 -SecurityEnabled $True
Assign a security group in Azure AD to a role
In the sharing panel, select Assign a security role under Data permissions.
Select the Dataverse role(s) that you want to apply to the selected Azure AD user(s) or group(s):
What CMOS Settings Wrong, CMOS date/Time Not Set?
The CMOS Settings Wrong, CMOS Date/Time Not Set are telling you the date on the device is not set.
what is CMOS? CMOS is Complementary Metal–Oxide–Semiconductor or CMOS RAM, Non-Volatile RAM (NVRAM), Non-Volatile BIOS memory: Most CMOS batteries will last the lifetime of a motherboard, up to 10 years in most cases.
1- It’s possible if the device was a long time without power and the CMOS battery is drained out or either the CMOS battery is dead.
1- Solution A – if the CMOS battery is not dead you connect to power and set the date and time and let the device charge that battery. If after a long time you can remove the power cable and reconnect it. If you restart the device and do you still seeing the same message about “CMOS Settings Wrong”: Definitely the CMOS battery is dead!
2- Solution B – You will replace the CMOS battery; you search by brand and model and buy a new battery.

Microsoft form with upload file, Who can fill in this form?
The option; Anyone can respond -is disabled when the form has an upload file:
File upload is only available when “Only people in my organisation can respond” is the selected setting
When you add a file upload to a form, the form cannot be shared with anyone link and is restricted to other people within your organization.
Who can fill in this form?
The reason is that uploaded files for personal forms are stored in the form creator’s OneDrive for Business account, at date of 24/12/2020 only the users inside the Office 365(Active Directory) can access the form with the upload option.
