Should You Turn Your Computer Off At Night?

This is a question I have heard for as long as I can remember.

This argument goes all the way back to my childhood and the early days of computers. Back then, computer parts, especially hard drive, wear out much faster than they do today. So, the argument was that to make your computers last longer, you should always shut it down at nights. My mother would yell at me to turn off the computer and go to bed.

Whether you shut down your computers during the night, is now a personal preferences. If you want your computer to do things like back up, updates or other intensive task, you can schedule them at nights while you are not using your systems. To run these task your computer has to be on.

If you’re concerned about saving energy, turn it off. Or you can use one of your computer has many power-saving modes, which are more convenients for getting it going again in the morning.

Hack Wi-Fi With The Same SSID To Create Fake Access Point

Have you ever gone to a big public place like an airport or an arena? You know they have hundreds of APs. But when you try to connect you only see 1 AP (SSID) instead of the hundreds that you know are there.

This is where an evil genius would ask, “What will happen if I started a wifi hotspot with the same SSID?”

This is called an evil twin attack. When a device tries to connect to an SSID it will connect to which ever device has the strongest signal. This is normally the closest AP. This type of attack works best in a place that offers free wifi.

Once someone connects to your evil twin AP, you can sniff their traffic and get all of their credentials. If the user checks their banking information, then now you have all of their banking information.

Warning

Always be very careful when you use “free public wifi” you never know who could be watching you.
