Aircrack-ng Termux |top| Info
Leo smiled. “I audited our own router. That’s the ethical part. Now let’s change the password to something stronger.” | What Leo Learned | Why It Matters | |----------------|----------------| | Monitor mode rarely works on internal Android Wi-Fi | You need a rooted phone + external USB Wi-Fi adapter (with OTG cable) for real penetration testing. | | Aircrack-ng in Termux works for cracking captures | If you obtain a .cap file legally (e.g., from your own router or test lab), aircrack-ng runs fine. | | Wordlists are essential | Without a good wordlist like rockyou.txt , cracking is nearly impossible. | | Ethics are non-negotiable | Only test networks you own or have written permission to audit. | The Happy Ending Leo’s friend changed the Wi-Fi password to BlueMuffin$42 — strong, unique, and not in any dictionary. Leo documented the test, thanked his friend, and used the experience for his cybersecurity homework.
After a few seconds of reconnection attempts, he stopped the capture ( Ctrl+C ). He copied the .cap file and ran:
ip a On Android, it was wlan0 . Leo asked his friend to disconnect and reconnect to the network. Meanwhile, Leo ran: aircrack-ng termux
sudo tcpdump -i wlan0 -s 0 -w handshake.cap Note: sudo may not work without root; on non-rooted devices, he used tcpdump -i wlan0 -w capture.cap and hoped the chip allowed promiscuous mode.
He turned on his phone’s Wi-Fi, connected to the target network (his own), and found the interface name: Leo smiled
aircrack-ng -w /usr/share/wordlists/rockyou.txt handshake.cap He had to download rockyou.txt first:
His friend was amazed. “You did that just from your phone?” Now let’s change the password to something stronger
pkg update && pkg upgrade pkg install root-repo pkg install aircrack-ng He also installed tcpdump and termux-api (to check Wi-Fi status). Leo’s internal Wi-Fi couldn’t go into monitor mode. So he couldn’t use airodump-ng to scan. But he had a backup plan: capture a WPA handshake passively using tcpdump while his friend reconnected to the router.
