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.
And Leo’s final advice to you: “Aircrack-ng on Termux is a powerful learning tool — but respect the law. Use it on your own lab, your own router, or with explicit permission. Otherwise, you’re not a hacker; you’re a criminal.” Want to try it safely? Set up a free virtual lab with aircrack-ng on Kali Linux instead of relying on Termux’s limitations. Your future self will thank you. aircrack-ng termux

First, he updated Termux:
Late one evening, Leo, a cybersecurity student, sat in a bustling coffee shop. His friend had just lost the Wi-Fi password to their shared study group’s router. “No problem,” Leo said, pulling out his Android phone. “Let me show you how we audit our own network’s security.” Step 1: The Setup (No Root? No Problem — Mostly) Leo opened Termux . He knew that Android’s Wi-Fi chip is locked down — no monitor mode without a rooted device and a compatible external adapter. But for basic WPA handshake capture on his own, authorized network , he could still use aircrack-ng in limited ways. Otherwise, you’re not a hacker; you’re a criminal
After a few seconds of reconnection attempts, he stopped the capture ( Ctrl+C ). He copied the .cap file and ran:
