You Should Know:

1. Scanning for Malware with VirusTotal via CLI

curl -X POST https://www.virustotal.com/vtapi/v2/file/scan -F 'apikey=YOUR_API_KEY' -F '[email protected]'

Check results:

curl -X GET 'https://www.virustotal.com/vtapi/v2/file/report?apikey=YOUR_API_KEY&resource=FILE_HASH'

2. Checking Breached Passwords

Use `curl` with Have I Been Pwned API:

curl -s "https://api.pwnedpasswords.com/range/$(echo -n 'password123' | sha1sum | cut -c1-5)" | grep $(echo -n 'password123' | sha1sum | cut -c6-40 | tr '[:lower:]' '[:upper:]')

3. Scanning Networks with Shodan

Install Shodan CLI:

pip install shodan
shodan init YOUR_API_KEY

Search for exposed webcams:

shodan search 'webcamxp'

4. Running OpenVAS Vulnerability Scan

Start OpenVAS in Kali Linux:

sudo openvas-start

Authenticate and scan a target:

omp --username=admin --password=admin --xml="<create_task><name>Scan</name><target><hosts>192.168.1.1</hosts></target></create_task>"

5. Analyzing URLs with URLScan

Submit a URL for scanning:

curl -X POST "https://urlscan.io/api/v1/scan/" -H "Content-Type: application/json" -d '{"url":"https://example.com", "public": "on"}'

6. Sandboxing Malware with Hybrid Analysis

Upload a suspicious file via API:

curl -X POST "https://www.hybrid-analysis.com/api/v2/submit/file" -H "api-key: YOUR_API_KEY" -F "[email protected]"

What Undercode Say:

Cybersecurity tools are essential for threat detection, but automation via CLI enhances efficiency. Always:

  • Monitor logs (journalctl -xe for Linux, `Get-WinEvent` for Windows).
  • Check open ports (netstat -tuln or ss -tuln).
  • Scan for vulnerabilities (nmap -sV -A TARGET_IP).
  • Analyze traffic (tcpdump -i eth0 -w capture.pcap).
  • Harden systems (sudo ufw enable for firewalls).

For deeper security:

  • Audit permissions (find / -perm -4000 -type f 2>/dev/null).
  • Check cron jobs (crontab -l).
  • Inspect kernel modules (lsmod).

Expected Output:

 Example: Shodan search results 
200 OK 
1. 45.33.12.10 - WebcamXP (HTTP) 
2. 67.205.15.22 - Exposed Database (MongoDB)

Example: Have I Been Pwned result 
password123 found in 3,456,789 breaches. 

Stay vigilant with these tools and commands to secure your systems effectively. �🔒
