  • 3.2Hack Password Menggunakan Pyrit

Password Attack

Password Cracking adalah proses menyerang password dari data yang telah tersimpan atau dikirim oleh sistem komputer. Pendekatan yang umum digunakan adalah brute force attack dengan cara berulang kali mencoba menebak password.

Tujuan cracking password mungkin untuk membantu pengguna memulihkan password yang lupa (walaupun menginstal password yang sama sekali baru akan mengurangi dari risiko keamanan, namun melibatkan hak istimewa sebagai Sistem Administrator), untuk mendapatkan akses tidak sah ke sistem, atau sebagai tindakan pencegahan oleh Administrator Sistem untuk memeriksa password yang mudah rusak. Secara file-by-file, cracking password digunakan untuk mendapatkan akses ke bukti digital dimana hakim mengizinkan akses namun akses file tertentu dibatasi.

Programmer komputer telah mencoba membuat algoritma untuk memecahkan password dalam waktu yang lebih singkat. Sebagian besar tool cracking password mencoba masuk dengan setiap kemungkinan kombinasi kata-kata. Jika login berhasil, berarti password sudah ditemukan. Jika password cukup kuat dengan kombinasi angka, karakter dan karakter khusus, metode cracking ini mungkin memakan waktu berjam-jam sampai berminggu-minggu atau berbulan-bulan. Beberapa tool cracking password menggunakan kamus yang berisi kata sandi. Tool ini sangat bergantung pada kamus, jadi tingkat keberhasilannya lebih rendah.

Tips untuk membuat Password yang kuat

Semakin panjang password, semakin sulit di crack: Panjang password adalah faktor yang paling penting. Jika anda memilih password pendek, tool cracking password dapat dengan mudah memecahkannya dengan menggunakan beberapa kombinasi kata. Password yang lebih panjang akan memakan waktu lebih lama untuk menebak. Password Anda harus minimal 8 karakter.

Selalu gunakan kombinasi karakter, angka dan karakter khusus: Ini adalah hal lain yang membuat password sulit dipecahkan. Tool cracking password mencoba kombinasi satu per satu. Memiliki kombinasi karakter kecil, huruf kapital, dan karakter khusus. Misalkan jika anda hanya memiliki angka dalam password anda. Tool cracking password hanya perlu menebak angka dari 0-9. Disini hanya panjang password yang menjadi penentu. Tapi memiliki kombinasi kata kunci a-z, A-Z, 0-9 dan karakter spesial lainnya yang cukup panjang akan membuat lebih sulit untuk di crack. Password semacam ini terkadang memakan waktu berminggu-minggu untuk dipecahkan.

Keragaman dalam password: Satu hal penting yang harus selalu Anda jaga. Jangan pernah menggunakan kata sandi yang sama di mana saja. Penjahat cyber bisa mencuri password dari satu situs web dan kemudian mencobanya di situs lain-nya.

Contoh strong password: AdZfL48024@ #$!

Tool yang digunakan untuk Password Cracking

• GPU Tools
• Online Attack
• Offline Attack
• Passing The Hash

GPU Tools

GPU, atau unit pemrosesan grafik, digunakan terutama untuk aplikasi 3-D. Ini adalah prosesor chip tunggal yang menciptakan efek pencahayaan dan men-transformasi objek setiap kali 3D scene digambar ulang. Ini adalah tugas-tugas yang intensif secara matematis, yang akan cukup membebani CPU. Memindahkan beban ini dari CPU akan membebaskan siklus CPU digunakan untuk pekerjaan lain.

Alasan sederhana dalam menggunakan GPU daripada CPU untuk memecahkan password adalah karena GPU lebih cepat. Ternyata cracking passwords sangat mirip dengan Bitcoin mining, jadi alasan yang sama GPU lebih cepat untuk Bitcoin mining berlaku untuk cracking password. Jawaban singkatnya adalah bahwa ada banyak chip khusus pada GPU yang melakukan operasi 32-bit dengan sangat cepat. Meskipun CPU dapat melakukan banyak perhitungan untuk keperluan umum, chip pada GPU dapat melakukan jenis operasi tertentu lebih cepat, dan dengan cara lebih mem-paralel-kan proses.

Hack Password Menggunakan Pyrit

Step 1:

Set Wi-Fi menjadi mode monitor dengan airmon-ng. Buka terminal dan ketik:

Catatan: airmon-ng akan me-rename wlan0 menjadi mon0.

Step 2:

Capture Traffic menggunakan airodump-ng. Ini akan menangkap traffic dan menampilkan informasi seperti, BSSID (AP MAC address), power, jumlah beacon frame, jumlah data frame, channel, speed, encryption (if any), dan juga, ESSID (biasanya kita mengenalkan sebagai SSID). Ketik:

Semua AP yang terlihat akan tampil di bagian atas layar, client akan berada di bagian bawah layar.

Step 3:

Menggunakan airodump-ng menangkap Handshake. Langkah ini adalah memfokuskan usaha kita pada satu AP pada satu channel, dan menangkap data penting dari AP tersebut. Kita perlu men-set BSSID dan channel untuk itu. Ketik pada terminal,

Dimana

• 08:86:30:74:22:76 adalah AP BSSID
• -c 6 adalah channel dimana AP beroperasi
• WPAcrack adalah nama file untuk menyimpan hasil
• mon0 adalah adapter wifi yang memonitor jaringan

Catatan: paling asik kalau kita bisa memperoleh AP yang konfigurasi-nya default tidak diubah oleh user.

Step 4:

Aireplay-Ng Deauth

Untuk mendapatkan password yang dienkripsi, kita harus meminta klien untuk melakukan otentikasi terhadap AP. Jika sudah diautentikasi, kami dapat membatalkan otentikasi (kick off) dan sistem mereka akan secara otomatis mengautentikasi ulang, di mana kita dapat mengambil password terenkripsi mereka dari proses tersebut.

Buka terminal baru, ketik:

Setelah berhasil menangkap handshake, gunakan pyrit untuk crack wifi password.

Offline Attack

Cmospwd

CmosPwd is a cross-platform tool to decrypt password stored in CMOS used to access a computer’s BIOS setup.

Crunch

Crunch is a wordlist generator where you can specify a standard character set or a character set you specify. crunch can generate all possible combinations and permutations.

Generate a dictionary file containing words with a minimum and maximum length of 6 (6 6) using the given characters (0123456789abcdef), saving the output to a file (-0 6chars.txt):

hash-identifier

Software to identify the different types of hashes used to encrypt data and especially passwords.

John the Ripper

John the Ripper is another well-known free open source password cracking tool for Linux, Unix and Mac OS X. A Windows version is also available. This tool can detect weak passwords. A pro version of the tool is also available, which offers better features and native packages for target operating systems. You can also download Openwall GNU/*/Linux that comes with John the Riper.

Combine the provided passwd (passwd) and shadow (shadow)(shadow) and redirect them to a file (> unshadowed.txt):

Using a wordlist (–wordlist=/usr/share/john/password.lst),

apply mangling rules (–rules) and attempt to crack the password hashes in the given file (unshadowed.txt):

johnny

Johnny provides a GUI for the John the Ripper password cracking tool.

RainbowCrack

RainbowCrack is a hash cracker tool that uses a large-scale time-memory trade off process for faster password cracking than traditional brute force tools. Time-memory trade off is a computational process in which all plain text and hash pairs are calculated by using a selected hash algorithm. After computation, results are stored in the rainbow table. This process is very time consuming. But, once the table is ready, it can crack a password must faster than brute force tools.

Download naruto ultimate ninja heroes 3 psp iso highly compressed. You also do not need to generate rainbow tablets by yourselves. Developers of RainbowCrack have also generated LM rainbow tables, NTLM rainbow tables, MD5 rainbow tables and Sha1 rainbow tables. Like RainbowCrack, these tables are also available for free. You can download these tables and use for your password cracking processes.

This tool is available for both Windows and Linux systems.

rcracki-mt

rcracki_mt is a modified version of rcrack which supports hybrid and indexed tables. In addition to that, it also adds multi-core support.

Crack the password hash (-h 5d41402abc4b2a76b9719d911017c592) using 4 CPU cores (-t 4) and the specified rainbow tables (tables2/md5/):

RSMangler

RSMangler will take a wordlist and perform various manipulations on it similar to those done by John the Ripper the main difference being that it will first take the input words and generate all permutations and the acronym of the words (in order they appear in the file) before it applies the rest of the mangles.

Use the original wordlist (cat words.txt |) and mangle words with a minimum length of 6 (-m 6) and maximum length of 8 (-x 8), using stdin as input (–file -) and redirecting the results to a new wordlist (> mangled.txt): root@kali:~# cat words.txt | rsmangler -m 6 -x 8 --file - > mangled.txt

chntpw

It is used to Removing Windows OS Passwords.

So Lets' get started:

Step 1: Mounting the drive containing Windows OS-> This one is easy ain't it? Well so that you might not have forgotten how to do it, I'll type the syntax:

Rick ross mastermind download zip.
Note that 'sda1' in above command is the partition on which Windows OS is installed yours can be different. To check yours simply type fdisk -l which will list your all partitions and then check by yourself on which partition your Windows OS is installed.

Step 2: Now move to the config folder of windows os using below command:

Step 3:Type the following command to see the list of users available on Victim's Machine:

Step 4:Copy the name of user whose password you want to crack and then enter the below command to crack the password of selected user:

dictstat

It is used to Generate dictionary file statistics

fcrackzip

fcrackzip is a fast password cracker partly written in assembler. It is able to crack password protected zip files with brute force or dictionary based attacks.

1.Open Terminal type fcrackzip –help this command will open fcrackzip with help options

2. Let’s make a zip file in windows 7 PC than we will copy paste it into Kali Linux afterthat we will try to break this password by fcrackzip. I created a zip file. This zip file’s password is 12345678.

3. Now we are going to break this password protected zip file. If you know your password has numeric (ex- 123.) and how many digits there in your password. Here we know our password is numeric (e.g. 123…) and its total 8 digits. If you have just small thought or knowledge about your password It will you to speed up your brute force attack against your zip file.

Syntax – fcrackzip –u –c <your password character type> –p <total digits> zip file path

Here,

The –u option, Try to decompress the first file by calling unzip with the guessed password. This weeds out false positives when not enough files have been given.

The –c option lets you select the character set, '1' here means password can be a numeric.

The -p option lets you select an initial string to start brute-force attack

Note – as you can see I wrote ‘aaaaaaaa’, if you will count this is total 8 digits means I assumed that my password can be 8 digits but in this step if my assumption will be wrong, like my password have 8 digits and I will write there ‘aaaaaaa’ (only 7 digits) than fcrackzip will not crack your password.

4. If you know your password is numeric but you don’t know there are how many digits. You can assume a password digit range. Here I am thinking that my password can be minimum 4 digits to maximum 8 digits.

Syntax – fcrackzip –u –c <your password character type> -l <password digits range> zip file path

5. In this Example I created another Zip file with small (lower case) alphabet digits as password. Here password is ‘abcdefgh’. If your password has small alphabets characters and length of password is 8 digits.

Syntax – fcrackzip –u –c <your password character type> –p <total digits> zip file path

Here we are using ‘a’ after –c because our password has small (lower case) alphabet. If you have doubt that the password can be capital (upper case) alphabet than you have to write capital ‘A’. If you think that your password has both upper and lower case than you can write ‘Aa’. Just like this if you doubt your password has lower case (a), Upper case (A), numeric (1). You have to write there ‘Aa1’.

6. Range of password digits

7. Here we are using brute force a zip file password which has upper case (A), lower case (a), numeric (1), and symbol (@). Use '!' for including special characters !:$%&/()=?{[]}+*~#. If you want to specify only some of the characters then mention them using ' : '. In this image I want to specify only one (@) character so I used :@.

Synaptics touchpad driver windows 10 acer download. 8. Now we are going to crack this zip password by using dictionary attack. Just for an example I am making a small dictionary manually so it will take less time to crack.

9. Now run the command for cracking this zip file password

Syntax – fcrackzip –u –D –p <dictionary file path> <zip file path>

opcrack

A Microsoft Windows password cracker using rainbow tables

Ophcrack uses Rainbow Tables to crack NTLM and LM hashes into plain text, its a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. If you have a complex password it will take a lot longer than simple passwords, and with the free tables your password may never be cracked.

sipcrack

SIPcrack is a SIP login sniffer/cracker that contains 2 programs: sipdump to capture the digest authentication and sipcrack to bruteforce the hash using a wordlist or standard input.

sipcrack bruteforces the user’s password with the dump file generated by sipdump. If a password is found, the sniffed and cracked login will be updated in the dump file.

Sipcrack needs a wordlist to launch an attack. As a result, it will give you the password.

“John the Ripper” – is a fast password cracker. Its primary purpose is to detect weak Unix passwords.

Most likely you do not need to install “John the Ripper” system-wide.

Instead, after you extract the distribution archive and possibly compile the source code (see below), you may simply enter the “run” directory and invoke John from there.

Compiling “John the Ripper”

Step 1: Download the latest version of ““John the Ripper”” and its signature

Step 2: Confirm the signature

This is a safety measure as we are dealing with dangerous thing.

Install the public key:

Check the signature:

You will see the message similar to the above. Ignore the warning as long as it says Good signature from “Openwall Project … “.

The warning is normal, see http://www.kernel.org/signature.html for more details.

Step 3: Uncompress and compile the sources

Note the make target for your system and type:

Where <system> is the appropriate make target. Alternatively, if your system is not listed, use:
