SQL Injection Attack — one of the oldest bugs, still one of the most dangerous.

SQL injection happens when user input is treated as executable SQL instead of data. A single unsafe query can expose sensitive data, bypass authentication, or even destroy entire tables.

String interpolation inside raw SQL is a red flag. It allows attackers to inject malicious logic directly into your query. Sanitizing input helps, but it is not enough on its own.

The real fix is parameterized queries.
When parameters are used correctly, the database engine treats input strictly as data — not executable code. No matter...

SQL Injection Explained

A malicious user inputs something like:

' OR '1'='1

This input alters the SQL query:

SELECT * FROM users WHERE username='' OR '1'='1';

Because '1'='1' is always true, the query returns all rows from the users table instead of a specific user.

This allows attackers to bypass login or extract entire databases without authorization.

Prevention Tips:
✅ Always use prepared statements or parameterized queries.
✅ Sanitize and validate all user inputs.
✅ Apply least privilege principles on database access.

🔎 What is 𝐘𝐚𝐧𝐝𝐞𝐱 𝐝𝐨𝐫𝐤𝐢𝐧𝐠? (Advanced OSINT Technique)

Most bug hunters know about Google Dorks…

But very few explore the power of Yandex Dorking using Yandex 🔥

Yandex is a Russian search engine that sometimes indexes files and directories that Google ignores — making it extremely powerful for reconnaissance and OSINT.

💡 Why Yandex is Special?

✔️ Different indexing algorithm
✔️ Better exposure of open directories
✔️ Sometimes reveals sensitive files not visible on Google
✔️ Useful for bug bounty & recon

Installation:
Open PHPMyAdmin, create a database and import hashtag.sql.
Open config/class/needy_class.php and fill in your PDO, path and email.
Open config/declare.php, config/class/needy_class.php & public/js/modules.js and replace the DIR variable containing my root path with your root path. (Note: do not add a slash at the end!).
Open .htaccess, go to line 17 and replace it with your root path.
If the "Back Time" function does not work correctly (forward or backward), go to config/class/time.class.php and play with line #8. Enjoy!!
