Cool Hacking Command

2011-12-13T22:45:00.000-08:00

1) ping : This command will allow you to know if the host you pinging is alive, which means if it is up at the time of executing the “ping” command.
Code:
ping x.x.x.x (x is the IP address)
or
ping www.whatever.com (www.whatever.com is the website you want to ping, but you don't know the IP)

OBS: Keep in mind that if the host you pinging is blocking ICMP packets, then the result will be host down.
2) nslookup : This command has many functionalities.
One is for resolving DNS into IP.
Lets say you know the website URL but you don’t know its IP(and you want to find out).
nslookup www.whatever.com (www.whatever.com is the website you want to find out the IP)
Now, another really nice function of nslookup is to find out IP of specific Mail Severs.
Code:
Code:

nslookup (enter) set type=mx (enter) yahoo.com

This command will give you the mail server IP of yahoo.com. You can use whatever server you want and if it is listed on DNS, then you get the IP. Simple, isn’t it?

3) tracert : This command will give you the hops that a packet will travel to reach its final destination.
OBS: This command is good to know the route a packet takes before it goes to the target box.
Code:
tracert x.x.x.x (x is the IP address)
or
Code:
tracert www.whatever.com (www.whatever.com is the website you don't know the IP)

4) arp : This command will show you the arp table. This is good to know if someone is doing arp poisoning in your LAN.
Code:
Code:

arp -a

5) route : This command will show you the routing table, gateway, interface and metric.
Code:
Code:

route print

6) ipconfig : This command will show tons of very helpful things.
Your IP, gateway, dns in use.
Code:
Code:

ipconfig

or
Code:
ipconfig /all

this command will give all that info but for all networks you might have it.
Also, in case you have a dynamic IP and want to change it, then type…
Code:
Code:

ipconfig /release (this will release your IP) ipconfig /renew (this will renew your iP)

OBS: Keep in mind that those commands will change your IP, but the new IP will still be tighed up to you. So don’t do anything stupid.
7) netstat : This command will show you connection to your box.
Code:
netstat

or
Code:

netstat -a (this will show you all the listening ports and connection with DNS names) netstat -n (this will show you all the open connection with IP addresses) netstat -an (this will combined both of the above)

8)nbtstat : This command will show you the netbios name of the target box.
Code:
nbtstat -A x.x.x.x (x is the IP address) nbtstat -a computername

net view x.x.x.x or computername (will list the available sharing folders on the target box)
Now some hints:
Code:
net use \ipaddressipc$ "" /user:administrator

(this command will allow you to connect to the target box as administrator)
Now if you want to connect to the target box and browse the entire C drive, then use this command:
Code:
net use K: \computernameC$

(this will create a virtual drive on your “my computer” folder)
OBS: Keep in mind that this will only works if the target box doesn’t have an administrator password set.
And least but not last, the “help” command.
Code:
whatevercommand /help

or
Code:

whatevercommand /?

This command will help you to understand what it does and all the switchs available for each command.
Very useful if you know the command, but forgot the right switch.

Enjoy........

How to Use Windows 7 Without Activation

2011-09-29T02:54:00.000-07:00

Most of you might be aware of the fact that it is possible to use Windows 7 and Vista for 120 days without activation. This is actually possible using the slmgr -rearm command which will extend the grace period from 30 days to 120 days. However in this post I will show you a small trick using which it is possible to use Windows 7 without activation for approximately an year! Here is a way to do that.

1. Goto “Start Menu -> All Programs -> Accessories” . Right click on “Command Prompt” and select “Run as Administrator“. If you are not the administrator then you are prompted to enter the password, or else you can proceed to step-2.

2. Now type the following command and hit enter
slmgr -rearm

3. You will be prompted to restart the computer. Once restarted the trial period will be once again reset to 30 days. You can use the above command for up to 3 times by which you can extend the trial period to 120 days without activation.

4. Now comes the actual trick by which you can extend the trial period for another 240 days. Open Registry Editor (type regedit in “Run” and hit Enter) and navigate to the following location
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

5. In right-side pane, change value of SkipRearm to 1.

6. Now you will be able to use the slmgr -rearm command for another 8 times so that you can skip activation process for another 240 days. So you will get 120 + 240 = 360 days of free Windows 7 usage.
120 days using “slmgr -rearm” command before registry edit

+

240 days using “slmgr -rearm” command after registry edit

= 360 Days

How to Detect Anonymous IP Addresses

2011-05-10T02:54:00.000-07:00

As the fraudsters are now becoming more sophisticated in bypassing the Geo-location controls by using proxies (Anonymous IPs) to spoof their IP address, it has become very much necessary to come up with a means for detecting the proxies so that the authenticity of the users can be verified. Using a proxy (web proxy) is the simplest and easiest way to conceal the IP address of an Internet user and maintain the online privacy. However proxies are more widely used by online fraudsters to engage in cyber crimes since it is the easiest way to hide their actual Geo-location such as city/country through a spoofed IP address. Following are some of the examples where fraudsters use the proxies to hide their actual IP.

1. Credit Card Frauds
For example, say a Nigerian fraudster tries to purchase goods online with a stolen credit card for which the billing address is associated with New York. Most credit card merchants use Geo-location to block orders from countries like Nigeria and other high risk countries. So in order to bypass this restriction the credit card fraudster uses a proxy to spoof his IP address so that it appears to have come from New York. The IP address location appears to be legitimate since it is in the same city as the billing address. A proxy check would be needed to flag this order.

2. Bypass Website Country Restrictions
Some website services are restricted to users form only a selected list of countries. For example, a paid survey may be restricted only to countries like United States and Canada. So a user from say China may use a proxy so as to make his IP appear to have come from U.S. so that he can earn from participating in the paid survey.

3. Proxy Detection Services
So in order to stop such online frauds, Proxy Detection has become a critical component. Today most companies, credit card merchants and websites that deal with e-commerce transactions make use of Proxy Detection Services like MaxMind and FraudLabs to detect the usage of proxy or spoofed IP from users participating online.

Proxy Detection web services allow instant detection of anonymous IP addresses. Even though the use of proxy address by users is not a direct indication of fraudulent behaviour, it can often indicate the intention of the user to hide his or her real IP. In fact, some of the most used ISPs like AOL and MSN are forms of proxies and are used by both good and bad consumers.

How Proxy Detection Works?

Proxy detection services often rely on IP addresses to determine whether or not the IP is a proxy. Merchants can obtain the IP address of the users from the HTTP header on the order that comes into their website. This IP address is sent to the proxy detecting service in real time to confirm it’s authenticity.

The proxy detection services on the other hand compare this IP against a known list of flagged IPs that belong to proxy services. If the IP is not on the list then it is authenticated and the confirmation is sent back to the merchant. Otherwise it is reported to be a suspected proxy. These proxy detection services work continuously to grab a list or range of IPs that are commonly used for proxy services. With this it is possible to tell whether or not a given IP address is a proxy or spoofed IP.

How to Tell Whether a given IP is Real or a Proxy?

There are a few free sites that help you determine whether or not a given IP is a proxy. You can use free services like WhatisMyIPAddress to detect proxy IPs. Just enter the suspected IP in the field and click on “Lookup IP Address” button to check the IP address. If it is a suspected proxy then you will see the results something as follows.

Internet Security, Protection, Habits and Cybercrime

2011-02-26T04:49:00.000-08:00

The nature and tactics of cybercriminals is rapidly changing. Operating systems, software and network equipment that used to protect your network probably no longer work. The habits that we use to work on the Internet have also changed and may have opened doors for hackers, malware and more
report from the Blue Coat WebPulse service and the Blue Coat Security Lab provide a comprehensive overview of the changing ways in which people are using the Internet and the new methods cybercrime is using perpetrate attacks.

As conditions and platforms change our use of the Internet also changes in response.

The current 2010 communication platforms based on usage are:

1) Social Networking

2) Personal Pages/Blogs

3) Chat/Instant Messaging

4) Email

Webmail has fallen to 17th place ( falling from ninth in 2009, and fifth in 2008)

Web search patterns for 2010 have changed from previous years:

1) Audio/Video Clips

2) New/Media

3) Reference

Personal search categories that were popular in previous years have lost position and declined in use, perhaps based on the state of the economy.

4) Dating/Personals

5) Pornography

8) Adult/Mature Content

With this change in usage come a shift in tactics used by cyber criminals. The landscape for 2010 revealed some noticeable shifts:

1) Cybercrime repositioned itself to take advantage of Social Networking relationships and infect friends and followers with malware. Phishing and click-jacking attacks on social networks became the most common types of attacks in 2010. The main focus of these attacks is to obtain user credentials that might also be the user name and password for banking, financial and other online accounts.

2) Use of hacked websites and email addresses of legitimate companies. Rather than using free domains as a penetration point sites with trusted reputations and good page rank and category recognition became the hackers preferred places from which to host an attack.

3) Attacks by malware moved to categories which would slip through spam filters and site block filters.

For example, Online Storage ranked second and Open/Mixed Content ranked sixth on the list of sites hosting malware. In fact, the number of new Online Storage sites hosting malware increased 13 percent and the number of new Open/Mixed Content sites hosting malware increased 29 percent. Interestingly, both of these categories would easily slip past most company’s filtering systems.

Based on the findings of this report many lessons can be learned to better protect employees and confidential data.

1) Web defenses must analyze data in real time and provide immediate attack alerts since attacks that only last for a few hours can still cause huge damage.

2) A defense that only utilizes reputation ratings will leave its users exposed to malware attacks from legitimate sites.

3) Web access never sleeps so network protection must provide security 24/7 regardless of location.

4) Malware can not be deterred through the use of data governance or automated prevention parameters. A dynamic Web defense must be implemented that can identify command and control servers and block data to/from those servers.

Set comprehensive policies, update your firewalls and make sure your network equipment systems and software have you protected against malicious attacks.

Access Gmail through Outlook Mobile

2010-02-01T18:22:00.000-08:00

Gmail offers both POP and IMAP e-mail access. Though both POP and IMAP enable you to access e-mail through Microsoft Office Outlook Mobile, using IMAP provides more benefits. With POP you can only download e-mail from your Inbox to your Windows Mobile phone. Any changes that are made to your phone’s mailbox will not be reflected in your Gmail account and vice versa. For instance, if you create a folder in Office Outlook Mobile, the same folder will not be visible in your online Gmail account, and vice versa. However, with IMAP you will see folders that you create in Office Outlook Mobile and folders that you create in Gmail. You don’t need to sort e-mails into various folders in Outlook Mobile if you have already done so in your Gmail account. Also with IMAP, if you check your e-mail on multiple devices, you can view the latest e-mail from any of the devices.

Setup Your Own Hot Spot :

2009-11-06T18:46:00.000-08:00

Definition:What is Hot Spot ?

A Hot-spot is a venue that offers Internet access over a wireless LAN through the use of a shared Internet. In general, a hot spot provides users' unfettered access to the Internet via one or more wireless access points.
Well, how to set up your own hot spot, from determining your coverage area to installing and controlling access to your network. However, before we begin, make sure your ISP lets you share your Internet connection. Some companies don't care, while it may be a violation of your Terms of Service with others.

Before you start:

Who want this connection.
Where you want them to connect
What your ISP's connection-sharing policy is for your service
Which network resources on your network require protection from hot-spot users

Follow the Steps:

Determine Hot-Spot Coverage: The goal of a hot spot is to cover a public area with an 802.11 signal. Most of the decisions about how and where to mount your access point and what antenna to use will depend on your desired coverage area. For small areas close to the physical location of your access point, a standard device such as one offered by your service provider or any wireless routers you can get off-the-shelf would do the job. Draft N (or 802.11n or Wireless-N) routers are faster and offer larger coverage than 802.11g routers.

Well, if you want to provide coverage to a municipal park a mile away, you will need to attach a more sensitive antenna and establish a line-of-site connection between your access point and the hot-spot location.

Wireless Standards & Characteristics

802.11
Operates at 2.4GHz; the lowest common denominator of the IEEE wireless LAN standards; provides bandwidth of only 1Mbps; equipment based on this older standard may be hard to find
802.11b
Operates at 2.4GHz; backward compatible with the older 802.11 standard; delivers bandwidth of up to 11Mbps. This once-popular standard is becoming obsolete and routers/access points based on this standard are hard to find.
802.11g
Operates at 2.4GHz; delivers bandwidth of up to 54Mbps; backward compatible with 802.11b; currently has the largest user base, especially in mobile hand held applications
802.11n
Also called Draft N; operates at 2.4GHz and 5GHz ; currently a draft specification awaiting ratification by the IEEE; delivers bandwidth of up to 300Mbps; backward compatible with 802.11g and b (when operated at 2.4Ghz); we expect this standard to co-exist with 802.11g as the standards of choice.
Bluetooth
Operates at 2.4GHz; is a short-range, low-bandwidth solution designed to connect peripheral devices without the use of cables; is not compatible with any of the above standards; is not well suited for hot-spot deployment.

Steps 2,

Choose an antenna type: If you use a Wireless-N router and have a relatively small area to cover, say a restaurant or a cafe, the built-in antenna of the router should suffice. For larger area, you will need a high-gain antenna capable of bridging the gap.

High-gain antennas concentrate radiation in a certain direction, in much the same way that flashlights focus beams of light. A low-gain, omni directional antenna spreads the signal in a 360-degree circular pattern, whereas a high-gain antenna focuses the signal in a particular direction, reducing the coverage from 360 degrees to 180 degrees or less. However, because a high-gain antenna delivers a more-concentrated radiation pattern, it's capable of spanning a greater distance. For example, a 24dB-gain antenna may reduce your coverage to a 10-degree swath of space but will dramatically increase the sensitivity and range of your access point in one direction.

Connect the antenna: Once you've determined the appropriate antenna based on your desired coverage area, you'll need to attach it to your access point or wireless router. (A wireless router is a regular router with a built-in access point). While most antennas feature N or SMA connectors, access points can vary.

Step 4

Mount the antenna: If your entire setup sits inside, mounting the antenna should prove easy. However, if your rig sits outside, you will need to put your access point into a weatherproof case. Just how much weatherproofing you need to make the enclosure depends on the local climate. There are both commercial and home-brew options available, depending on your level of crafting skills, it can range from something as simple as putting the device in a close box or elaborate.

Step 5
Lock down your Network: Generally, if your hot spot is open to the public, you'd want to separate it from your home or office network while allowing it to share your access to the Internet.

A VPN, or Virtual Private Network, is a connection between two endpoints - a VPN Router, for instance – in different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This establishes a private network that can send data securely between these two locations or Networks. This is done by creating a “tunnel”. A VPN tunnel connects the two PCs or networks and allows data to be transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a connection secured by encrypting the data sent between the two Networks. VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private Network. Using industry standard encryption and authentication techniques - IPSec, short for IP Security - the VPN creates a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual Private Networking can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road (travelers can connect to a VPN Router using any computer with
VPN client software that supports IPSec, such as SSH Sentinel.)

There are two basic ways to create a VPN connection:

•VPN Router to VPN Router
•Computer (using VPN client software that supports IPSec) to VPN Router

The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with VPN client software that supports IPSec can be one of the two endpoints. Any computer with the built-in IPSec Security Manager (Microsoft 2000 and XP) allows the VPN Router to create a VPN
tunnel using IPSec). Other versions of Microsoft operating systems require additional, third-party VPN client software applications that support IPSec to be installed.

A Virtual Private Network (VPN) is a connection between two endpoints - a VPN router, for instance - in different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This establishes a private network that can send data securely between these two locations or networks through a "tunnel." A VPN tunnel connects two PCs or networks and allows data to be transmitted over the Internet as if it were still within those networks. It is a connection secured by encrypting the data sent between the two networks.

To setup a VPN Tunnel on a Linksys router you need to perform four steps:
1.Connecting Devices Together
2.Verifying the VPN Settings Needed on the Two Routers
3.Configuring VPN Tunnel settings on Router A
4.Configuring VPN Tunnel settings on Router B

Connecting Devices Together

Before connecting to a VPN tunnel you need to ensure that there is an active Internet connection between the two routers that will communicate. After ensuring that there is an active Internet connection, you need to verify the VPN settings. To verify the VPN settings of the two routers, follow the instructions below.

Verifying the VPN Settings Needed on the Two Routers

In order for you to successfully configure a VPN tunnel, you need to take note of the settings needed to set-up a tunnel. To verify the settings needed for your VPN Tunnel follow the steps below.

Step 1:
Access the router's web-based setup page.
Step 2:
Click Status then under WAN/Gateway take note of the Internet IP Address.
Step 3:
Click Status then LAN and take note of the IP Address.

Router A's Status page:

Router B's Status page:

Step 4:
Make sure the Local IP Address of the two routers are different. Take note that the Local IP Address of Router A will be Router B's Remote Secure Group.
Note: Change the Local IP Address of a Linksys router if necessary.
In this example, we will use the following:

Step 5:
After verifying the settings needed to setup a tunnel, you need to configure the settings on Router A. For instructions, follow the steps below.
Configuring VPN Tunnel settings on Router A

Step 1:
Access the router's web-based setup page.
Step 2:
When the router's web-based setup page appears, click VPN.

Step 3:
Look for IPsec VPN Tunnel then select Enable.
Step 4:
Under Tunnel Name enter the name you want to set your tunnel. In this example "tunnel1" was used.

Step 5:
Look for Local Secure Group and select either Subnet, IP Addr. or IP Range, then on the fields provided enter the appropriate values of the router. In this example, we selected Subnet and entered "192.168.1.0" for the IP since this is the LAN segment of the local router and "255.255.255.0" for the Mask.

Step 6:
Under Remote Security Group, select either Subnet, IP Addr., IP Range, or Any, then on the fields provided enter the appropriate values of the remote router. In this example, we selected Subnet and entered "192.168.2.0" for the IP since this is the LAN segment of the remote router and "255.255.255.0" for the Mask.

Step 7:
Look for the Remote Security Gateway drop down menu and select either IP Addr. or Any, then enter the WAN/Internet IP address or the DDNS of the remote router. In this example, we selected IP Addr. and entered "10.100.16.60" for the IP Address field since this is the Internet IP address of the remote router.

Step 8:
Under Encryption, select 3DES since this is the only Encryption type supported.
Note: Make sure the Encryption level selected is the same with the router you wish to establish a VPN tunnel with.
Step 9:
Under Authentication, select the authentication mode you wish to enable on your tunnel. In this example we used SHA1.
Note: Make sure the Authentication mode selected is the same with the router you wish to establish a VPN tunnel with.

Step 10:
Under Key Exchange Method, select Auto (IKE).
Step 11:
Make sure PFS is set to Enable. This will ensure that the initial key exchange and IKE proposals are secured.

Step 12:
Under Pre-Shared Key, enter the key you want to enable on your tunnel. In this example "MyPresharedKey" was used.
Step 13:
Under Key Life Time, enter the time period you want the key to expire on your tunnel. In this example "28800" was used.

Note: Make sure the Pre-shared Key and Key Life Time entered are the same with the remote router.
Step 14:

Step 15:
After verifying the settings needed to setup a tunnel, you need to configure the settings on Router B. For instructions, follow the steps below.
Configuring VPN Tunnel settings on Router B

Step 1:
Access the router's web-based setup page.
Step 2:
When the router's web-based setup page appears, click VPN.

Step 3:
Look for IPsec VPN Tunnel then select Enable.
Step 4:
Under Tunnel Name enter the name you want to set your tunnel. In this example "tunnel1" was used.

Step 5:
Look for Local Secure Group and select either Subnet, IP Addr. or IP Range, then on the fields provided enter the appropriate values of the router. In this example, we selected Subnet and entered "192.168.2.0" for the IP since this is the LAN segment of the local router and "255.255.255.0" for the Mask.

Step 6:
Under Remote Security Group select either Subnet, IP Addr., IP Range, or Any, then on the fields provided enter the appropriate values on your router (this values should be from the remote router). In this example we select Subnet and enter "192.168.1.0" for the IP since this is the LAN segment of the remote router and "255.255.255.0" for the Mask.

Step 7:
Look for the Remote Security Gateway drop down menu and select either IP Addr. or Any, then enter the WAN/Internet IP address or the DDNS of the remote router. In this example, we selected IP Addr. and entered "22.15.160.53" for the IP Address field since this is the Internet IP address of the remote router.

Step 8:
Under Encryption, select 3DES since this is the only Encryption type supported.
Note: Make sure the Encryption level is the same with the router you wish to establish a VPN tunnel with.
Step 9:
Under Authentication, select the authentication mode you wish to enable on your tunnel. In this example we used SHA1.
Note: Make sure the Authentication mode is the same with the router you wish to establish a VPN tunnel with.

Step 10:
Under Key Exchange Method, select Auto (IKE).
Step 11:
Make sure PFS is set to Enable. This will ensure that the initial key exchange and IKE proposals are secured.

Step 12:
Under Pre-Shared Key, enter the key you want to enable on your tunnel. In this example "MyPresharedKey" was used.
Step 13:
Under Key Life Time, enter the time period you want the key to expire on your tunnel. In this example "28800" was used.

Note: Make Sure the Pre-Shared Key and Key Life Time Entered are the same with the remote Router
