Differences Between Virus, Trojans, Spyware..

The Internet has become one of the greatest technological achievements of the century, but as is usually the case, the Internet also has a dark side. We’re referring to all the threats that lurk on the web, ready to infect our computers as soon as we take one wrong step. These threats are usually known viruses, trojans and spyware.

Nevertheless, the first step in solving a problem is to truly understand what you’re dealing with. Many PC owners refer to all of these threats simply as “viruses”, but that’s a rather generic term. Let’s find out the main differences between these threats, and why you shouldn’t mistake one for the other.

What are Viruses?

In a nutshell, a computer virus is a program that has the ability to infect a PC, while copying itself and spreading from one file to another. When sharing an infected file, a virus is capable of infecting the target computer as well, further spreading and multiplying.

Viruses are generally designed to wreak havoc on your computer, by corrupting and deleting files. In the worst case scenario, viruses can make your computer inoperable, until you completely disinfect it using anti-viruses, or by formatting the HDD and re-installing a fresh copy of the OS.

What is a Trojan?

Unlike viruses, trojans are malicious programs that don’t have the ability to replicate themselves. Trojans also cannot infect a computer without the consent of the user, so in theory, they shouldn’t be a threat at all. Who would want to infect his or her computer anyway? Well, the trick is that trojans come disguised as harmless or useful programs. Once the user agrees to unknowingly install a trojan, the program usually create a “backdoor” on the machine, allowing remote access to the PC.

A computer infected with a trojan can be used for DoS attacks in order to attack websites, proxy servers, or for sending spam.

What are Spyware?

The term Spyware defines a wide range of malicious programs that are designed specifically for gathering personal information on the user. Most often than not, spyware come in the form of keyloggers, which register and learn passwords as well as credit card numbers. They generally register keyboard strokes and capture screenshots.

The information is then sent back to the creator of the spyware, which can use the personal information for nefarious purposes – usually for stealing money from bank accounts, breaking into email accounts and more.

That’s all for today, and remember. Keep your computer safe, and keep your anti malware software up to date.

7 Must Have Tools For Every Hacker

7 Must Have Tools For Every Hacker

Its been a while since I have posted about some hacking tools and with increasing number of emails asking me to do an  article on it, I finally decided to cover it up.Hacking tools are developed by some really good coders out there to ease out many complex tasks which have to be done manually and took painstakingly great deal of time and effort.All these tools provided here are free of cost,are tried hands on and are being actively developed by community,and if not,their alternatives are provided.To summarize it up, these are the 7 must have tools for every hacker out there.

1. Nmap 
I think everyone has heard of this one, Nmap (Network Mapper) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts.Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use,and dozens of other characteristics. It may be used to discover computers and services on a computer network, thus creating a "map" of the network.Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source.Can be used by beginners (-sT) or by pros alike (packet_trace). A very versatile tool, once you fully understand the results.

Download Nmap

2. Nessus Remote Security Scanner 
Recently went closed source, but is still essentially free. Works with a client-server framework.Nessus is the worlds most popular vulnerability scanner used in over 75,000 organizations world-wide. Many of the worlds largest organizations are realizing significant cost savings by using Nessus to audit business-critical enterprise devices and applications. 

Download Nessus

3. Wireshark 
Wireshark is a GTK+-based  network protocol analyzer, or sniffer, that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and to give Wireshark features that are missing from closed-source sniffers. Works great on both Linux and Windows (with a GUI), easy to use and can reconstruct TCP/IP Streams! . 

Download Wireshark

4. Cain and Abel 
The swiss knife of hacking tools..Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, revealing password boxes, uncovering cached passwords and analyzing routing protocols.The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. 

Download Cain and Abel

5. Kismet 
Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. Kismet will work with  any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g traffic. A good wireless tool as long as your card supports rfmon 

Download Kismet

6. NetStumbler 
Yes a decent wireless tool for Windows! Sadly not as powerful as it’s Linux counterparts, but it’s easy to use and has a nice interface, good for the basics of war-driving. NetStumbler is a tool for Windows that allows you to detect Wireless Local Area Networks (WLANs) using 802.11b, 802.11a and 802.11g. It has many uses:

1. Verify that your network is set up the way you intended.
2. Find locations with poor coverage in your WLAN.
3. Detect other networks that may be causing interference on your network.
4. Detect unauthorized rogue access points in your workplace.
5. Help aim directional antennas for long-haul WLAN links.
6. Use it recreationally for WarDriving.

Download NetStumbler

7. SuperScan
Powerful TCP port scanner, pinger, resolver. SuperScan 4 is an update of the highly popular Windows port scanning tool, SuperScan. If you need an alternative for nmap on Windows with a decent interface, I suggest you check this out, it’s pretty nice.

Top 10 Computer Tricks Every Person Should Know

SEXPAND

We've talked before about the things every computer user should know how to do, but we geeks are special: we want to go above and beyond, to explore every nook and cranny of our system and make everything easier. Here are ten ways to do just that.P

10. Find New Uses for the Programs You Already HaveP

Chances are, you've probably already found a few awesome tools and added them to your productivity arsenal, but most programs can be used for more than just their inteded purpose. The file-syncing Dropbox, for example, is also great for monitoring your home computer, printing files from afar, and even downloading stuff with BitTorrent. Savvy folks can use Gmail to store files in the cloud or find out if someone's stolen your laptop. Any tool can become multipurpose if you know its ins and outs.P

9. Use the Command Line Like a NinjaP

Using the command line isn't as exciting as it looks in the movies, but it can be a very useful tool (in fact, some tools are just better in the command line). It's pretty easy to learn, too—check out our command line primer for beginners to learn some basic commands. Once you've got that down, read up on the best shortcuts that help you navigate the command line like a ninja. Those guides apply to UNIX-based systems like Linux and OS X, but if you're a Windows user you can grab something like Cygwin to get a similar experience (or, if you want a more Windows-centric tool, try Powershell).P

8. Read and Understand Your Resource UsageP

When your computer starts acting a little slow, a lot of people jump to their resource monitor to see what's causing problems. However, just looking at a bunch of charts and graphs isn't going to tell you what's wrong unless you really know what you're looking for. High CPU is a common problem with one app slowing your system down, and as soon as you close it, the issue should go away. High network activity could be the cause of slow internet or slow file transfers over the network. RAM usage, however, is where a lot of people get thrown off: high RAM usage isn't inherently a bad thing. Know the difference between good and bad RAM usagebefore you start blaming processes. If you want to keep an eye on your resources, check out ourfavorite system monitors for Windows, Mac, and Linux, too.P

7. Run Everything on a ScheduleP

Stop performing all that system maintenance yourself and set it all up to run on a schedule. With Windows' built-in Task Scheduler, you can run just about any kind of task—whether it'smaintenance, picture uploads, or even a simple alarm—through Windows' built-in tools (in fact, it's one of the best Windows 7 features you've probably forgotten about). Mac users looking for something similar should check out Tasks Till Dawn.P

SEXPAND

6. Know Your OS's Hidden FeaturesP

Every operating system has hidden things lying under the hood, you just have to know where to look. Windows users should check out the hidden features of Windows 7 and Windows 8, while Mac users should peruse the hidden features of OS X Lion and Mountain Lion. If you want to find even more, you can often find them in Windows' Registry or in OS X's terminal. System tweakers like Ultimate Windows Tweaker, OnyX for Mac, and Ubuntu Tweak are also great places to find secret features.P

SEXPAND

5. Learn to Crack Passwords (and Protect Yourself)P

Everyone should know how to create a secure password, but responsible geeks can take it a step further by learning how to break into a comptuer. This skill—whether used on a Windows machine or a Mac—can really help you understand how computer thieves and hackers will try to get at your data. Learning the process means you know how to protect yourself against the process—not just with strong passwords but with encryption and other settings tweaks that keep thieves out. Similarly, you may also want to learn how to crack a Wi-Fi network's WEP and WPA password.P

SEXPAND

4. Navigate Everything With Your KeyboardP

There are certain basic keyboard shortcuts everyone should know, but if you really want to use your computer more efficiently, you can take it so much further. Learn the most common shortcuts for your favorite programs, like Gmail, Microsoft Word, basic text boxes, and even Facebook. After a little while, you'll be able to blow through menus and text boxes with unbelievable speed. Check out our guide to becoming a keyboard ninja, complete with a bunch of cheat sheets to help get you off the ground.P

3. Run a Basic Linux DistributionP

Even if you don't want to switch operating systems, knowing a few Linux basics can be really handy. With a live CD on hand you can troubleshoot your machine, revive an old, slow PC, and make your way through Linux-based DIY projects. Check out our five-part guide to getting started with Linux, and be careful—it can be quite the rabbit hole once you get into it!P

2. Squeeze More Power Out of Your HardwareP

With a bit of tweaking, you can push your hardware past its original limits and get some pretty serious bang for your buck. When it comes to your PC, you can overclock your processor and video card, and even install OS X on non-Macs by building a Hackintosh. And, while you're at it—even though it isn't a computer trick specifically—you should try turning your $60 router into a $600 router with DD-WRT.P

1. Program Your Own Dead Simple ScriptsP

You don't need to learn an entire programming language to write advanced scripts. Windows users can do a ton of awesome stuff with AutoHotkey, from creating simple keyboard shortcuts to controlling their PC remotely. To get started, just check our beginner's guide to AutoHotkeyand our list of the best AutoHotkey tricks. Mac users don't have anything quite like AutoHotkey, but you can do quite a bit with the built-in, insanely easy-to-learn AppleScript. If you aren't the coding type, check out Automator on the Mac and its clone, Actions on WindowsP

When all is said and done, this is probably way more than 10 tricks, but if you don't know any of the above, they should keep you busy for awhile. If you have an idea we didn't list, be sure to mention it in the comments below.P
