This realization sends your blood pressure through the roof and you feel sick to your stomach. Your immediate first thought: how the heck did they get MY password? This thought is followed by, what have they done with it, and how much damage are they doing right now? Data Breaches It may not even be your fault. One way a hacker may have obtained your password is via a massive corporate data breach. Unfortunately, data breaches have become a fact of life these days. It seems like every other day there is some news story about a large corporation falling victim to a hack attack resulting in the exposure of customer information, oftentimes including passwords. As soon as you hear about a data breach possibly involving one of your accounts you should take immediate action. One of the first steps you should take is to change the password on your affected account immediately after the organization affected by the breach says it's safe to change your password. Your Password Was Too Simple Sometimes a password that is too simple can be a hacker's way into your account. Hackers can use brute force cracking tools, password dictionary tools, and other means to obtain your password. The simpler your password, the shorter time it will take to crack your password. Make your password as long as allowable by the system that you're using. Make your password complex and random. Avoid using whole words or parts of words when creating a password as these are easily crackable by hacker tools. Avoid easy keyboard combinations (i.e. 123456, or qwerty).

Sniffing Your Network Traffic (Evil Twin Hotspot or by Other Means) So you're at the coffee shop surfing the Internet on your notebook minding your own business, what you don't realize is that hackers may be listening in on all of your network traffic. Another method hackers use to obtain passwords is setting up phony Wi-Fi hotspots in public areas. These hotspots, known as Evil Twins may be given the same name as a legitimate hotspot in hopes that victims will mistakenly connect to their phony one instead of the real one. Once connected to the "Evil Twin" hotspot, hackers can eavesdrop on the data stream and potentially intercept passwords without victims even knowing it. Cracked Wi-Fi If your Wi-Fi network password isn't complex enough, then you might have it cracked by Wi-Fi Hackers. If you're using outdated wireless encryption such as the highly-crackable Wired Equivalent Privacy (WEP) encryption, then there is a very strong chance that your network could be "owned" in a matter of minutes. Cracking WEP has become a trivial task thanks to freely available WEP cracking tools that are available on the Internet for anyone to download. Change your wireless network security standard to WPA2 (or better if available). You should also definitely choose a wireless network password that isn't easily guessed or cracked as well. Follow the same rules as above for creating a strong password for your wireless network password. Additionally, your network's name or SSID can be a security risk as well. You should make sure that you're not using a default network name or a common one.
