Re: Crack Password Rar Backtrack 3
Christian Erdmann
I've installed BackTrack 5 R3, a security testing distro, onto a USB drive, and I can get it to boot up, but I'm stuck in the BusyBox shell. Everybody says "just log in with username root and password toor, then type startx to launch the GUI, but startx reports "command not found". I've tried various commands such as "login" and "sh", but no luck. sudo is out of the question, too.
Note: This post demonstrates how to crack WEP passwords, an older and less often used network security protocol. If the network you want to crack is using the more popular WPA encryption, see our guide to cracking a Wi-Fi network's WPA password with Reaver instead.
Patience with the command line. Thisis an ten-step process that requires typing in long, arcane commands andwaiting around for your Wi-Fi card to collect data in order to crackthe password. Like the doctor said to the short person, be a littlepatient.
Microsoft stores the password hashes of Windows user accounts in the registry hive c:\windows\system32\config\sam. This file is highly protected and not accessible while Windows is running even for the administrator user. To circumvent the protection and access the SAM file, we need to boot from a Live CD such as BackTrack so we can hack Windows password in the SAM registry file.
The method that I describe in this tutorial can works with any computer running Windows 7/Vista/XP system. To get started, you need to download a live edition of BackTrack Linux distribution and burn that ISO image to a CD (you could also burn BackTrack on a USB drive). Either way, you will need to boot in to Linux to hack your forgotten Windows 7/Vista/XP password.
I am planning to run backtrack in Live USB mode with persistent memory, can I change the password of root, because my friends will certainly mess up with the files if it has default root/toot credentials.
Well I've recovered a WEP Wi-Fi password using Aircrack-ng, and it says the password is 00:00:00:00:00 in hex, which is five times null. Backtrack represents the password in ASCII as dots, but I've tried that and it naturally didn't work. How do I enter that? I'm running Win8.1 / Backtrack. I've googled that null on Win is alt + 255, but that didn't work for me.
The company I work for recently took over another car dealership franchise and location. Currently there is a wireless ap setup and 4 laptops, 2 diag scanners, and 2 printers are all associated and working fine. They are adding another 2 laptops and 1 more diag scanner. I can't find any documentation of the security settings on the AP. The prior IT person left me with a password for the AP itself, but not the WEP key and I'd really hate to have to redo all them with a new key. Is there a way to decrypt the key in the AP? Is there a way of getting the key out of one of the existing laptops? They are Toughbooks with Intel Proset software. I can copy the profile and possibly get it working on the toughbook but not the additional scanner.
Unless I am mistaken, if you save the configuration to a TFTP server, the passwords stay encrypted, but, preshared Keys, come across in clear text.
This may be the case for WEP keys as well, I do not have any Aironets to test on.
There are many "tools" to get the password revealed, however, leaving the same password put you in the main seat of the risk wagon, anybody that knows that password can tap into the system and wreak havoc, I will strongly suggest you change it.
Well I ended up resetting the password on ALL the devices (took a whole day to do this because of how the testers are setup) and everything linked back up except the newest tester. I linked up once, got DHCP from our server, then after a poweroff it seems to be unable to obtain an IP address. Thanks for everyone's help.
My thought process in justifying putting out a step by step on how to hack passwords on the internet is because posting this would 1) promote awareness of how easy this is to do and 2) to provide a recommendation on readily available tools that could increase security. The other reason is these methods are in no way earth shattering and readily available on youtube.
Passwords that are long, random and unique are the most difficult to crack. But humans tend to use weak passwords made up of familiar phrases and numbers. Mike Meyers demonstrates just how easy it is to hack a weak Wi-Fi password in this episode of Cyber Work Applied.
(0:00- 0:24) WPA and WPA2 are very good encryptions. If you're using WPA, you're using RC4, but you're using TKIP with that. If you're using WPA2 while you're using AES with CCMP, then you are not going to be able to crack these passwords, except for one little problem.
(1:36- 2:15) Luckily for us, we know that human beings don't use good, randomized, long passwords. We know that most human beings are going to use a phrase and then a number. Or their pet's name and then the date they were born, or the number of kids they have and their wife's name and the date that they got married. Little, simple, things like that.
We'll put a really weak password on here, then we're going to go back over to the Kali box and in this case, what we're going to do is we're still going to monitor the traffic, but we're just going to wait for somebody to authenticate, and we got them. We'll run the cracker, and with luck, since it's a weak password, we're going to be able to get it pretty easily.
The next thing I'm going to do is go over to Wireless Security, and we're going to take off WEP, and let's go to WPA Personal. This type of attack will work with a WPA or WPA2 personal shared key. So I've already got a password here, and I want to keep it.
Hi, I wanted to make this post because I want to login to an old account I used to have for this game, my mom recovered it again after I forgot the password, that was years ago but now I don't remember the login information as well as the nickname/username of my account. Though I need that nickname in order to receive help from Niantic, can anyone help me on what I should do or if its even possible to get my old account I dont remember the nick or password to back? The account was tied under her email but we couldn't find any old emails that may have had the account username
Make sure the router password is not still set to the default password. If the password can be guessed this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys.
Also, if I remember correctly their use to be demo's for password recovery programs that would tell you how long the recoverable password was and the first 3 or 4 characters. Does anyone remember or know if they still exist - it would make brute forcing more targeted.
I have used backtrack to crack a neighbor's WPA2 password, and I am wondering if it is explicitly illegal. My thinking is that because I only captured a packet of data with a handshake, and then used hashcat to crack the password with a dictionary, I at no point had unauthorized access to the router, and my MAC was spoofed. I never actually used the password to access their network or connect to their router, I simply cracked the password and was done with it. Thanks for your advice, some of my friends are worried that I will get caught by the FBI.
In cryptanalysis and computer security, password cracking is the process of recovering passwords[1] from data that has been stored in or transmitted by a computer system in scrambled form. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password.[2] Another type of approach is password spraying, which is often automated and occurs slowly over time in order to remain undetected, using a list of common passwords.[3]
The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence to which a judge has allowed access, when a particular file's permissions restricted.
The time to crack a password is related to bit strength .mw-parser-output div.crossreferencepadding-left:0.mw-parser-output .hatnotefont-style:italic.mw-parser-output div.hatnotepadding-left:1.6em;margin-bottom:0.5em.mw-parser-output .hatnote ifont-style:normal.mw-parser-output .hatnote+link+.hatnotemargin-top:-0.5em(see Password cracking), which is a measure of the password's entropy, and the details of how the password is stored. Most methods of password cracking require the computer to produce many candidate passwords, each of which is checked. One example is brute-force cracking, in which a computer tries every possible key or password until it succeeds. With multiple processors, this time can be optimized through searching from the last possible group of symbols and the beginning at the same time, with other processors being placed to search through a designated selection of possible passwords.[4] More common methods of password cracking, such as dictionary attacks, pattern checking, word list substitution, etc. attempt to reduce the number of trials required and will usually be attempted before brute force. Higher password bit strength exponentially increases the number of candidate passwords that must be checked, on average, to recover the password and reduces the likelihood that the password will be found in any cracking dictionary.[5]
The ability to crack passwords using computer programs is also a function of the number of possible passwords per second which can be checked. If a hash of the target password is available to the attacker, this number can be in the billions or trillions per second, since an offline attack is possible. If not, the rate depends on whether the authentication software limits how often a password can be tried, either by time delays, CAPTCHAs, or forced lockouts after some number of failed attempts. Another situation where quick guessing is possible is when the password is used to form a cryptographic key. In such cases, an attacker can quickly check to see if a guessed password successfully decodes encrypted data.
