ZeroDays CTF: One Of The Biggest Cybersecurity Challenges In The World

ZeroDays CTF, founded by Mark Lane, is one of the most prominent cybersecurity challenges globally. It has gained significant recognition, with Team Ireland competing in ENISA’s European Cyber Security Challenge. The event recently sold out, but additional tickets were made available due to high demand. Cyber-Schools CTF is also fully booked, with a waiting list now active.

You Should Know:

Here are some essential commands and tools commonly used in Capture The Flag (CTF) challenges and cybersecurity practices:

1. Nmap (Network Mapper)

Scan a target IP for open ports:
```
nmap -sV -p 1-65535 <target_ip>
```
Aggressive scan with OS detection:
```
nmap -A <target_ip>
```

2. Metasploit Framework

Search for exploits:

msfconsole
msf6 > search <exploit_name>

Use an exploit:

msf6 > use exploit/<exploit_path>
msf6 > set RHOSTS <target_ip>
msf6 > exploit

3. John the Ripper (Password Cracking)

Crack a password hash:

john --format=<hash_type> --wordlist=<wordlist.txt> <hash_file>

4. Wireshark (Packet Analysis)

Analyze network traffic:
```
wireshark <capture_file.pcap>
```

5. Linux Command Line Tools

Find files with specific permissions:
```
find / -perm -4000 2>/dev/null
```
Check running processes:
```
ps aux
```
Monitor network connections:
```
netstat -tuln
```

6. Windows Command Line Tools

Check open ports:
```
netstat -an
```
List scheduled tasks:
```
schtasks /query /fo LIST /v
```
Check system information:
```
systeminfo
```
