According to the specialists of the hacking course, the attack works this way: When a user installs WhatsApp on their device, it receives a six-digit verification code via SMS, allowing you to activate the WhatsApp account. Threat actors must have a hacked account and write to a friend of the chosen victim.
As with anything in technology, it was only a matter of time before hackers cracked the code. Two-factor authentication is still one of the strongest security tools, but a new hack is putting it in jeopardy.

The most secure method for 2FA is through a timed code generator. Facebook, Microsoft, Google, and many banking apps use this. A 6-digital verification code is displayed for a few seconds and is only valid within a specified time. Tap or click here for more details.
A huge problem is PIN guessing from birthdays (dd/mm/yy lends to a 6 digit number that is easily guessed, dd/mm/yyyy for 8 digits). It's very often that a PIN number is taken from someone's birthday or year, either their own or relatives. There was even a case where a speaker had cracked the phone code of an audience live on-stage.
An analysis by DataGenetics on released/exposed/discovered password tables showed that four and six character pins are the most popular but all sizes of four or larger are used. From this analysis, it found that the most common five digit PIN (12345) in the sample appeared 22.802% of the time! That's about two times more than the most common four or six digit pin (1234 (10.713%) and 123456 (11.684%) respectively). I agree that using a five digit PIN to prevent using dates etc. is wise but in the US, postal zip codes are five digits and I could see people using them. Also, everyone with a single digit month birthday/anniversary etc. could easily use a mddyy PIN. The other interesting finding is the larger the PIN is, the more likely repetitive patterns begin to occur like 1234321 or 1212123. Key take away, the longer the pin the more humans will require a mnemonic to remember them.
For a properly secure digital code, you'd need 14 digits for an offline crack time to exceed a year, and that's assuming something robust like PBKDF2 (this chart assumes PBKDF2 with a speed of 300k guesses/sec) rather than the vastly more likely plaintext code storage.
PINs with five or seven digits may avoid current patterns with four or six digits, but as kenlukas's answer points out, this will simply shift what people choose in their bad attempts at obscurity, such as postal codes or dates. There are 75% odds of a date that fits mddyy (or ddmyy) since there are only three months that miss (365 minus the days in October, November, and December is 273, 273/365 = 75%). Increase that to allow mmdyy/dmmyy and single-digit years between 2000-2009 and it gets worse.
For dates, a six-digit code's 1000000 possibilities get reduced to 36525 and a birthdate can be narrowed to 1826 assuming you can guess the person's age within a five year span. (Five digit variations actually introduce complexity here, but it's not much.)
Still, more is always better, so moving a requirement from four to five is great, but you might as well go to six. Aspire to longer codes barring compatibility concerns (I remember a conversation in 2002 in which a friend couldn't use their bank card in Europe because that bank didn't support six-digit PINs).
You are getting network locked SIM card because your phone's network is still locked to the original network carrier. For the moment, your device can't be used alongside different SIM cards until it gets network unlocked by inserting 8 or 16 digits unlock code.
Before 2009, the code for unlocking Samsung mobiles was an 8 digit number. But after 2019 that changed. Now, Samsung uses 16 digit network codes. Some of the models require a defreeze code alongside the unlock code.
If you are getting the Invalid SIM card network locked SIM card inserted error message after changing your network provider, then it can be fixed pretty easily via a call to your previous service provider. They will provide you with an 8-16 digit code that will unlock the SIM card. But there are a few contract requirements that need to be met. Otherwise, they won't be providing you with the specific code. Here is the list of requirements:
As you see, there are many ways to help you solve iPhone asking for 6-digit passcode i never set 2022. You will never worry about the update requires passcode problem anymore. More than this, you can also use iToolab UnlockGo to remove Apple ID and bypass iCloud lock at the same time. Hope this article helps you!

This authentication method requires the user to provide their phone number when first setting up the account. When the user logs on, they must enter a verification code into their web browser or app (usually six digits long) that arrives via text message.
Attackers sometimes opt for a brute force approach depending on the age of the equipment being used by the target. For example, some legacy keyfobs are only four digits long and thus easier to crack (longer OTP codes increase the difficulty because there are more permutations to decipher).
Step 9: Verify your phone number to load WhatsApp chats.Enter your phone number and then click the "Next" button. When you receive a text message with a 6-digit code, simply enter the 6-digit code to start loading WhatsApp chats from Android. Note: Please make sure the phone number you enter is the same as the one used for the WhatsApp backup.
WhatsApp software automatically compares all the phone numbers from the device's address book with its central database of WhatsApp users to automatically add contacts to the user's WhatsApp contact list. Previously the Android and Nokia Series 40 versions used an MD5-hashed, reversed-version of the phone's IMEI as password,[179] while the iOS version used the phone's Wi-Fi MAC address instead of IMEI.[180][181] A 2012 update now generates a random password on the server side.[182]Alternatively a user can send to any contact in WhatsApp database through the url https:// api.whatsapp.com/send/?phone=[phone number] where [phone number] is the number of the contact including the country code.
As soon as the hacker has access to the WhatsApp account, he can set up a two-step verification. After that it is suddenly no longer possible for the legitimate owner of the account to take it back. This requires a six-digit code that only the attacker has. 2ff7e9595c
