Claves SSH débiles / PRNG predecible de Debian

Algunos sistemas tienen fallas conocidas en la semilla aleatoria utilizada para generar material criptográfico. Esto puede resultar en un espacio de claves dramáticamente reducido que puede ser atacado por fuerza bruta con herramientas como snowdroppe/ssh-keybrute. También están disponibles conjuntos pre-generados de claves débiles como g0tmi1k/debian-ssh.

STOMP (ActiveMQ, RabbitMQ, HornetQ y OpenMQ)

El protocolo de texto STOMP es un protocolo de mensajería ampliamente utilizado que permite una comunicación e interacción sin problemas con servicios populares de colas de mensajes como RabbitMQ, ActiveMQ, HornetQ y OpenMQ. Proporciona un enfoque estandarizado y eficiente para intercambiar mensajes y realizar diversas operaciones de mensajería.

Necesitas conocer el texto plano (o parte del texto plano) de un archivo contenido dentro del zip encriptado. Puedes verificar nombres de archivos y tamaño de archivos contenidos dentro de un zip encriptado ejecutando: 7z l encrypted.zip Descarga bkcrack de la página de lanzamientos.

# 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

Columna Protegida por Contraseña de Open Office

Si tienes un archivo xlsx con una columna protegida por una contraseña, puedes desprotegerlo:

• Cárgalo en google drive y la contraseña será eliminada automáticamente

• Para eliminarla manualmente:

unzip file.xlsx
grep -R "sheetProtection" ./*
# Find something like: <sheetProtection algorithmName="SHA-512"
hashValue="hFq32ZstMEekuneGzHEfxeBZh3hnmO9nvv8qVHV8Ux+t+39/22E3pfr8aSuXISfrRV9UVfNEzidgv+Uvf8C5Tg" saltValue="U9oZfaVCkz5jWdhs9AA8nA" spinCount="100000" sheet="1" objects="1" scenarios="1"/>
# Remove that line and rezip the file
zip -r file.xls .

Herramientas

Ejemplos de hash: https://openwall.info/wiki/john/sample-hashes

Hash-identifier

hash-identifier
> <HASH>

Wordlists

• Rockyou

• Probable-Wordlists

• Kaonashi

• Seclists - Passwords

Herramientas de Generación de Wordlists

• kwprocessor: Generador avanzado de teclado con caracteres base configurables, mapa de teclas y rutas.

kwp64.exe basechars\custom.base keymaps\uk.keymap routes\2-to-10-max-3-direction-changes.route -o D:\Tools\keywalk.txt

John mutation

Lee /etc/john/john.conf y configúralo

john --wordlist=words.txt --rules --stdout > w_mutated.txt
john --wordlist=words.txt --rules=all --stdout > w_mutated.txt #Apply all rules

Hashcat

Ataques de Hashcat

• Ataque de lista de palabras (-a 0) con reglas

Hashcat ya viene con una carpeta que contiene reglas pero puedes encontrar otras reglas interesantes aquí.

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

• Ataque combinador de listas de palabras

Es posible combinar 2 listas de palabras en 1 con hashcat. Si la lista 1 contenía la palabra "hello" y la segunda contenía 2 líneas con las palabras "world" y "earth". Se generarán las palabras helloworld y helloearth.

# 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 $!

• Ataque de máscara (-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

• Lista de palabras + Máscara (-a 6) / Máscara + Lista de palabras (-a 7) ataque

# 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
