Protect Your Devices from juice jacking

The concept is simple, leading smart phones on the market have been designed to utilize the same port for charging the phone as data transfer. This opens the opportunity to trick a user in need of a charge to expose their phone's data port. The attack encompasses many facets of information security, including security design, user awareness, attacks against system design/code, as well a bit of social engineering.


With juice jacking, the vulnerability or attack vector is the phone's USB port, the exposure factor is dependent on the user's awareness of this possible attack method and their phone's battery life. When these two factors come together, the unsuspecting user plugs their phone into a malicious system, the attack is able to take place. In the age where business executives travel regularly, and depend on access to their phones to respond to emails, check their schedule, etc.. (basic work functionality) this vector may come up more often then people presume.


How do I avoid it?

The most effective precautions center around simply not charging your phone using a third-party system. Here are some tips to help you avoid using public kiosk charger:

    1.Keep your devices topped off: Make it a habit to charge your phone at your home and office when you’re not actively using it or are just sitting at your desk working.

    2.Carry a personal charger: Chargers have become very small and portable, from USB cables to power banks. Get one and throw it in your bag so you can charge your phone anytime you’re at the office or while on-the-go if you use a power bank.

    3.Carry a backup battery: If you’re not keen on bringing a spare charger or power bank, you can opt to carry a full spare battery if your device has a removable battery.

    4.Lock your phone: When your phone is truly locked as in inaccessible without the input of a pin or equivalent passcode, your phone should not be able to be paired with the device it’s connected to.

    5.Power the phone down: This technique only works on phones on a model-by-model basis as some phones will, despite being powered down, still power on the entire USB circuit and allow access to the flash storage in the device.

    6.Use power only USB cables: These cables are missing the two wires necessary for data transmission and have only the two wires for power transmission remaining. They will charge your device, but data transfer is made impossible.

5 Best Programming Languages to Learn in 2017

Python has continued its upward trajectory from last year and jumped two places to the No. 1 slot, though the top four—Python, C, Java, and C++—all remain very close in popularity. Indeed, in Diakopoulos’s analysis of what the underlying metrics have to say about the languages currently in demand by recruiting companies, C comes out ahead of Python by a good margin.

The C programming language was created to redesign the UNIX operating system for use on multiple computers. When judged by programming language popularity, C has been one of the most stable languages ever created. C provides low-level access to memory and requires minimal run-time support. Many critical components of modern operating systems are written in C as is the whole Linux operating system. Even though most programmers understand C to some degree, only a minority use it on a regular basis.

With 22.7% market share, Java leads the index as the most popular programming language in the world. The reason behinds Java’s popularity is simple: Android. Any device that can run a Java virtual machine (JVM) can run all standard, dependency-free Java applications. 
Developers used to criticize Java for its inferior performance. But things have improved dramatically as the language continued to evolve. Anyone with a solid grasp of the language should find it easy to secure a good job as a software developer.  

The language was created by Bjarne Stroustrup, a Danish computer scientist, with the original name “C with Classes”. In 1979, Stroustrup came up with the idea to create a language that would combine the features found in the Simula programming language with the performance of C. The language quickly took off. It’s now used by most popular software projects: Windows, Chrome, all major applications of Adobe, etc. Its advantages over C and other most popular programming languages 2016 and 2017 include portability, exception handling, function overloading, a rich function library, efficiency, and speed.

Created by Microsoft, C# is a modern programming language that continues to evolve and improve with time. Developers use C# to write apps for the Windows operating system. Also, it’s one of a few programming languages supported by the incredibly popular game engine Unity. C# is fully open-source, and Microsoft has even released an open-source C# compiler, called Mono. Most operating systems, including Android, Linux, BSD, Mac OS X, and Solaris, can run Mono with no issues. C# programmers can enjoy access to all the .NET Framework class libraries. They include a comprehensive collection of reusable components.

MAC address spoofing Attack

MAC address spoofing tricks the switch into thinking your computer is something else. You simply change your computer’s MAC address and masquerade as another user.
You can use this trick to test access control systems, such as your IPS/firewall, and even your operating system login controls that check for specific
MAC addresses.

UNIX-based systems :

In UNIX and Linux, you can spoof MAC addresses with the ifconfig utility.
Follow these steps:

1. While logged in as root, use ifconfig to enter a command that disables
the network interface.

Insert the network interface number that you want to disable (usually,
eth0) into the command, like this:

[root@localhost root]# ifconfig eth0 down

2. Enter a command for the MAC address you want to use.

Insert the fake MAC address and the network interface number (eth0)
into the command again, like this:

[root@localhost root]# ifconfig eth0 hw ether
new_mac_address

You can use a more feature-rich utility called GNU MAC Changer (http://cut-urls.com/tmwwB) for Linux systems.




 Windows :

You can use regedit to edit the Windows Registry, but I like using a neat
Windows utility called SMAC (www.klcconsulting.net/smac), which
makes MAC spoofing a simple process. Follow these steps to use SMAC:

1. Load the program.
2. Select the adapter for which you want to change the MAC address.
3. Enter the new MAC address in the New Spoofed MAC Address fields and click the Update MAC button.
4. Stop and restart the network card with these steps:
a. Right-click the network card in Network and Dialup Connections and then choose Disable.
b. Right-click again and then choose Enable for the change to take effect. You might have to reboot for this to work properly.
5. Click the Refresh button in the SMAC interface. To reverse Registry changes with SMAC, follow these steps:
1. Select the adapter for which you want to change the MAC address.
2. Click the Remove MAC button.
3. Stop and restart the network card with these steps:
a. Right-click the network card in Network and Dialup Connections and then choose Disable.
b. Right-click again and then choose Enable for the change to take effect. You might have to reboot for this to work properly.
4. Click the Refresh button in the SMAC interface. You should see your original MAC address again.

MAC-daddy attack ARP poisoning

ARP poisoning can be hazardous to your network’s hardware and health,
causing downtime and more. So be careful!

Using Cain & Abel for ARP poisoning
You can perform ARP poisoning on your switched Ethernet network to test
your IPS or to see how easy it is to turn a switch into a hub and capture anything and everything with a network analyzer.

Perform the following steps to use Cain & Abel for ARP poisoning:
1. Load Cain & Abel and then click the Sniffer tab to enter the network analyzer mode. The Hosts page opens by default.
2. Click the Start/Stop APR icon (the yellow and black circle). The ARP poison routing (how Cain & Abel refers to ARP poisoning) process starts and enables the built-in sniffer.
3. If prompted, select the network adapter in the window that appears and then click OK.
4. Click the blue + icon to add hosts to perform ARP poisoning on.
5. In the MAC Address Scanner window that appears, ensure the All Hosts in My Subnet option is selected and then click OK.
6. Click the APR tab (the one with the yellow-and-black circle icon) to load the APR page.
7. Click the white space under the uppermost Status column heading (just under the Sniffer tab). This re-enables the blue + icon.
8. Click the blue + icon and the New ARP Poison Routing window shows the hosts discovered in Step 3.
9. Select your default route (in my case, 10.11.12.1).The right-hand column fills with all the remaining hosts, as shown in Figure 1.

Selecting your victim hosts for ARP poisoning in Cain & Abel

10. Ctrl+click all the hosts in the right column that you want to poison.
11. Click OK and the ARP poisoning process starts.
This process can take anywhere from a few seconds to a few minutes
depending on your network hardware and each hosts’ local TCP/IP
stack. The results of ARP poisoning on my test network are shown in
Figure 2.

 ARP poisoning results in Cain & Abel.

12. You can use Cain & Abel’s built-in passwords feature to capture passwords traversing the network to and from various hosts simply by
clicking the Passwords tab.


The preceding steps show how easy it is to exploit a vulnerability and prove
that Ethernet switches aren’t all they’re cracked up to be from a security
perspective.
