Default Credentials

Search in google for default credentials of the technology that is being used, or try these links:

One of the easiest and most overlooked attack vectors is the use of default usernames and passwords. Many systems, especially routers, cameras, IoT devices, web panels, and enterprise software, ship with default login credentials. These are often never changed — making them low-hanging fruit for attackers and red teamers alike.

Before launching a brute-force attack, always check whether the system uses default creds. You can often find these in documentation, online forums, or public lists.

📚 Top Resources for Default Credentials:

• DefaultCreds Cheat Sheet – GitHub

• Phenoelit Default Password List

• Vulnerability Assessment Default Passwords

• 192.168.1.1 Default Router Password List

• DataRecovery Default Passwords

Create Your Own Dictionaries

While default credential lists are a great starting point, custom wordlists tailored to your target dramatically increase the success rate of brute-force and dictionary attacks. By gathering intel about the target, you can generate personalized passwords that are far more likely to work.

Here are some effective methods and tools for building your own dictionaries:

Crunch – Custom Pattern Generator

crunch allows you to generate wordlists with fine control over length, character sets, and patterns.

# Length 4 to 6, using numbers and uppercase hex
crunch 4 6 0123456789ABCDEF -o crunch1.txt

# Length 4 only, using predefined charset
crunch 4 4 -f /usr/share/crunch/charset.lst mixalpha

# Pattern-based example
crunch 6 8 -t ,@@^^%%
@ = lowercase | , = uppercase | % = numbers | ^ = special characters

---

Website-Based Wordlists

Leverage content from target websites to generate relevant wordlists:

# Use CeWL to scrape words from a target site
cewl https://example.com -m 5 -w words.txt

# Tok grabs words from a list of URLs
cat urls.txt | tok

# Extract words from JS files (via getjswords)
cat js-urls.txt | python3 getjswords.py

---

CUPP (Common User Passwords Profiler)

Generate passwords based on personal info like name, birthdate, pets, etc.

python3 cupp.py -h

Wister – Wordlist Mutator

Create highly customized lists by combining keywords and patterns.

python3 wister.py -w john james 1025 summer london 1999 -c 1 2 3 4 5 -o wordlist.lst

 __          _______  _____ _______ ______ _____

Hashcat

Hashcat attacks

• Wordlist attack (-a 0) with rules

Hashcat already comes with a folder containing rules but you can find other interesting rules here.

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

• Wordlist combinator attack

It's possible to combine 2 wordlists into 1 with hashcat. If list 1 contained the word "hello" and the second contained 2 lines with the words "world" and "earth". The words helloworld and helloearth will be generated.

# 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 attack (-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

• Wordlist + Mask (-a 6) / Mask + Wordlist (-a 7) attack

# 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

If you have an xlsx file with a column protected by a password you can unprotect it:

• Upload it to google drive and the password will be automatically removed

• To remove it manually:

unzip file.xlsx

# Find something like: <sheetProtection algorithmName="SHA-512"

Weak SSH keys / Debian predictable PRNG

Some systems have known flaws in the random seed used to generate cryptographic material. This can result in a dramatically reduced keyspace which can be bruteforced with tools such as snowdroppe/ssh-keybrute. Pre-generated sets of weak keys are also available such as g0tmi1k/debian-ssh.

STOMP (ActiveMQ, RabbitMQ, HornetQ and OpenMQ)

The STOMP text protocol is a widely used messaging protocol that allows seamless communication and interaction with popular message queueing services such as RabbitMQ, ActiveMQ, HornetQ, and OpenMQ. It provides a standardized and efficient approach to exchange messages and perform various messaging operations.

Known plaintext zip attack

You need to know the plaintext (or part of the plaintext) of a file contained inside the encrypted zip. You can check filenames and size of files contained inside an encrypted zip running: 7z l encrypted.zip Download bkcrack from the releases page.

# 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

cat /usr/share/wordlists/rockyou.txt | 7za t backup.7z

#Download and install requirements for 7z2john
