ZeroDays Colleges CTF: A Must-Attend Event For Cybersecurity Enthusiasts

The ZeroDays Colleges Capture The Flag (CTF) event, sponsored by Bugcrowd, is a premier opportunity for cybersecurity enthusiasts to test their skills, learn new techniques, and network with industry professionals. This event is a must-attend for anyone interested in cybersecurity, ethical hacking, and penetration testing.

You Should Know:

CTF Basics: A Capture The Flag (CTF) competition is a cybersecurity challenge where participants solve security-related tasks to find “flags” hidden in various systems. These tasks can range from web exploitation, reverse engineering, cryptography, and more.
Preparation: Before attending a CTF, it’s essential to familiarize yourself with common tools and techniques. Here are some commands and tools you should know:

Nmap: A powerful network scanning tool.
```
nmap -sV -sC target.com
```

Metasploit: A penetration testing framework.

msfconsole
use exploit/windows/smb/ms17_010_eternalblue
set RHOSTS target.com
exploit

John the Ripper: A password cracking tool.

john --wordlist=/usr/share/wordlists/rockyou.txt hashfile.txt

Wireshark: A network protocol analyzer.
```
wireshark
```
Ghidra: A reverse engineering tool.
```

```

Practice Challenges: To prepare for the CTF, you can practice on platforms like:

– Hack The Box
– TryHackMe
– CTFtime

4. Common CTF Categories:

Web Exploitation: Finding vulnerabilities in web applications.
Reverse Engineering: Analyzing binary files to understand their functionality.
Cryptography: Solving challenges related to encryption and decryption.
Forensics: Analyzing data to find hidden information.

5. Linux Commands for CTF:

```

Privilege Escalation:

sudo -l
find / -perm -u=s -o -perm -g=s 2>/dev/null

6. Windows Commands for CTF:

System Information:
```
systeminfo
```
Network Configuration:
```
