If you forget this master password, all your other passwords in the database are lost, too. There isn't any backdoor or a key which can open all databases. There is no way of recovering your passwords.
If its correctly built (and by all accounts it is), your chances of recovering your password are very limited - luck, knowledge about yourself and your behaviour, you may be able to narrow down the key space and brute force it. There are tools to brute force Keepass files - see here. That said, its likely easier and faster to simply reset all your passwords.
Massive data dumps such as these become treasure troves for research of human behavior in the context of security. The US Company Preempt revealed that a staggering 35% of the passwords in the dump could already be found in password dictionaries available prior to the breach. Statistics like these remind us to keep our passwords as strong as possible.
Today we are going to perform a simple attack on a KeePass database file and attempt to break a master password. For those unfamiliar with the software, KeePass is a popular open source password manager. Say you have 50 different passwords for different purposes that you need to remember, how do you go about remembering them all? Some people will write them down in a book. Others may store them in a plain text file - definitely not recommended! A third approach is to use a software application like KeePass. What it does is encrypt all passwords provided to the tool using AES in combination with a master password and optionally a key file. When a user then wishes to recall any particular password they will provide their master password to the tool; in response, the tool will decrypt all passwords in plain text allowing the user to check the entry of their interest.
For the software system to verify the validity of the master password provided it will apply a hashing algorithm to the string given in concatenation with other data. All those who have meddled in the password cracking world know that whenever a hash is available a brute force or dictionary attack can be launched.
So how can we do this? The first step is to extract the hash out of the KeePass database file. Here is a KeePass database we created with a very simple password that we will use for the course of this tutorial.
We now have our extracted hash file ready to be cracked. The next step is to download a password cracking utility. The greatest by far is Hashcat available from here. What makes Hashcat the leader of such tools is its massive collection of predefined hashing algorithms and its ability to utilize a computers GPU to increase cracking speeds by an enormous degree.
As of Hashcat version 3.0 the software supports KeePass with no custom algorithms needed to be defined. We can run a quick grep command to learn the switch value of 13400 needed for our invocation of the binary.
Next, we need to make an edit to our hash file. The hashcat binary does not expect the name of our KeePass database to be pre-pended to our hash so we will have to trim the string with a text editor; after doing so our hash file will look as follows.
On average, each person has 27 online logins and passwords. They protect our bank accounts, our social media, our phones, and more. Passwords are the keys that unlock our digital lives. But what makes them so secure, and how can you make sure your passwords are doing a good job of protecting your information and your identity?
Fourth, implementing a two-step verification process that does not solely rely on your password adds an extra layer of security to your accounts. In this process, a one-time random security code is sent via a SMS message, a phone app, an auxiliary device like a token or smart card, or a secondary email address. Although it may be cumbersome to have an additional step before accessing your accounts, multi-factor authentication means that a hacker would need both your password and the one-time security code to access your account. Access to your account is, therefore, not achievable through a brute force attack.

For those who are unfamiliar, the original NES Metroid was one of many NES games to use passwords as a means to save progress.Later, this password system was leveraged to create unusual effects in the game by inputting invalid passwords. One of these passwords was "ENGAGERIDLEYMOTHERFUCKER" which bricked some versions of the game, and would later go on to break NES emulators, and even brick the systems they ran on.
ConsolidatePassword converts the password from characters into bytes, and stores it in memory at address $6988. The password in question is decoded into the byte sequence 39 74 0A 40 E6 D2 35 53 A2 59 87 51 39 B3 DE 31 43 9B. The last two bytes are special: the 43 indicates that the password should be deobfuscated by rotating it to the right by 0x43 bits, and the 9B is a checksum. ValidatePassword performs the rotation, and computes the checksum. The password then becomes the sequence 12 CC 3A 89 CD 9E F1 89 CB A0 52 07 36 91 AA 9D 43, which (by pure coincidence) happens to add up to 0x9B, meaning the checksum matches and the game treats it as a valid password rather than displaying the error screen.
Since this isn't actually a "real", meaningful password, this routine just ends up loading a bunch of nonsensical, meaningless values. The one that actually causes the game to crash is the InArea, which comes from the low 5 bits of byte 8 of the password, or 0xB.
But note that this table has only 5 entries! An area of 0xB (decimal 11) causes us to read well past the end of the table and into the next routine. The byte we read happens to be 0x84, which is not a valid bank number.
Unlike almost all other mappers, the MMC1 is configured through a serial port in order to reduce pin count. CPU $8000-$FFFF is connected to a common shift register. Writing a value with bit 7 set ($80 through $FF) to any address in $8000-$FFFF clears the shift register to its initial state. To change a register's value, the CPU writes five times with bit 7 clear and a bit of the desired value in bit 0. On the first four writes, the MMC1 shifts bit 0 into a shift register. On the fifth write, the MMC1 copies bit 0 and the shift register contents into an internal register selected by bits 14 and 13 of the address, and then it clears the shift register.
In other words: each time we write to an MMC register, bit 7 indicates whether we want to clear the shift register or write to it, and if we want to write then bit 0 indicates the bit we want to write. Bits 1-6 are ignored
However, when we try to switch banks to a value that's way out of range (0x83, because of the dey instruction), the first write has bit 7 set and actually resets the shift register rather than writing. The remaining 4 writes write to the shift register but do not trigger a bankswitch, since the MMC1 is waiting for a 5th write.
However, the shift register still contains 4 leftover bits from the failed bankswitch; it's contents (in binary) are x0001. The first write to the MMC1 register fills in the 5th bit (the x) and causes all 5 bits to immediately be written to the control register. This causes the MMC1 to suddenly switch into 32-KiB bank mode.
We've ended up misaligned in the instruction stream: note that one instruction starts at address C4C7, and the next starts at C4C9; but we're trying to execute the instruction starting at C4C8. The processor ends up interpreting the LDA operand (memory address $49) as an opcode, which happens to correspond to the instruction EOR #i. This doesn't do anything interesting, but it means that we're still misaligned and now attempting to execute address C4CA (the #$02 operand to the CMP). Opcode 02 is invalid; if executed, it just causes the CPU to freeze until the console is reset.
There's no way this crash could possibly cause any permanent damage to the cartridge or console. The 02 opcode itself could not cause any harm; it just locks up the CPU until the user presses the reset button or cycles the power. Besides, the Metroid NES cartridge included no persistent storage so there's no way to "brick" it. There were (to my knowledge) no other "versions" of Metroid released on the NES, so it's not possible that I investigated the wrong version.
As far as emulators: an accurate emulator should behave identically to the hardware, so the password will cause the game to crash on an emulator just as it would on hardware. But it's virtually impossible for the crash to actually have any effect on the system running; it would take an extraordinarily badly-written emulator to actually cause harm to the system it's running on if it encounters an invalid opcode.
Fundamentally these 'passwords' aren't really passwords as such, but map back to a string of bits that control the state of the game - so it's more of a string representation of the current state of the game than a password.
As the passed string is basically forcing the game into a set state, it's possible for it to be put into a state that the game manufacturer never intended it to be in - including states that simply make no sense in the context of the game. This can then lead to triggering bugs in the game that occur due to the invalid state that the writers never intended to occur (and thus obviously never handled/tested), resulting in crashes.
There's no reason whatsoever that you should be forcing your users to have a password length less than 16 characters, this is particularly egregious in 2020.When you combine this with "include one number and one letter" you see this is security theatre, this classic XKCD comic explains why limiting password length is not good for security in practice. Security theatre like this is incredibly damaging because of the false sense of security it creates and honestly I wish people would just stop it.
