General CTF Resources

Tips:

• CTFs require a variety of tools; check the questions for hints.
• Switching between Windows and Linux tools is common (e.g., Ghidra is easier to install on Kali).
• Organize your files in a dedicated CTF folder.
• Kali and SIFT VMs come with many useful tools; having both is helpful.
