Trik: Mendapatkan direct link APK/GPK dari Muzhiwan/Blackmart

Trik ini berguna kalo Anda pengen download app/game yang ukurannya besar dari “unofficial market tool” seperti muzhiwan atau blackmart (yang udah saya test). Prinsipnya adalah dengan membelokkan request http dari device -Android- ke squid cache proxy, sehingga bisa dicek requestnya di access.log si squid.

Bahan-bahan:

Android handset (saya pake NSFAT) yang udah terinstall aplikasi tersebut :D (muzhiwan/blackmart)
Laptop yang udah terinstall squid (dan udah dikonfigurasi tentunya) yang akan dijadikan router/gateway

Cara memasak:

Konfigurasi laptop sebagai router dulu kemudian hubungkan NSFAT dengan laptop (melalui jaringan ad-hoc) langkah-langkahnya bisa dicek disini. Kemudian jalankan perintah tambahan untuk meredirect semua request http (port 80) yang berasal dari wifi ke local port squid (default 3128).

iptables -t nat -A PREROUTING -i wlan0 -p tcp --dport 80 -j REDIRECT --to-port 3128

jadi kalo discript sebelumnya adalah:

iptables -t nat --flush
iptables -t filter --flush
iptables --flush
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables --append FORWARD --in-interface wlan0 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward

menjadi

iptables -t nat --flush
iptables -t filter --flush
iptables --flush
iptables -t nat -A PREROUTING -i wlan0 -p tcp --dport 80 -j REDIRECT --to-port 3128
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables --append FORWARD --in-interface wlan0 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward

Uji coba:
1. monitor access.log dari squid; (default /var/log/squid/access.log ), dengan perintah tail -f untuk realtime monitoring.

tail -f /var/log/squid/access.log

format output-nya kurang lebih begini:

2. Sambil menjalankan perintah diatas (di laptop), kembali ke NSFAT buka muzhiwan/blackmart, kemudian pilih game yang kita ingin dapatkan link apk-nya, pilih download:

dan ketika downloadnya udah mulai jalan pilih pause/stop:

kemudian “kembali ke laptop” harusnya ada penampakan seperti ini di squid access.log :

NB: kalo app yang g gede-gede amat ukurannya (tanpa data), file typenya apk, ini contoh pake blackmart: Buka blackmart, pilih app, kemudian pilih install/download:

kalo download udah jalan, pilih cancel.

Cek access.log squid di laptop, harusnya muncul penampakan seperti ini:

Tinggal copas aja link *.gpk/*.apk ke download manager kesukaan Anda, resume supported, multithread supported, dan yang paling penting NSFAT g kebakar :D
