Why Home Network Is 192.168.0.1 AS Default Gateway ?

Why Home Network Is 192.168.0.1 AS Default Gateway ?

Someone recently asked me why their wireless routers always had a default IP address of 192.168.0.1 and I really could not come up with a good answer! Being an IT guy myself, I was obviously irritated by the fact that I hadn’t really thought about something that’s in my face pretty much every day before.

New IoT malware targets IP cameras via known flaw

New IoT malware targets IP cameras via known flaw

At least 1,250 camera models produced by a Chinese manufacturer possess the bugs, the researcher went on to claim.In April, Trend Micro noticed a new malware that spreads by exploiting the same products via the recently disclosed flaws. The security firm estimates that about 120,000 cameras are vulnerable to the malware, based on Shodan, a search engine for internet-connected hardware. The Persirai malware is infecting the cameras to form a botnet, or an army of enslaved computers. These botnets can launch DDoS attacks, which can overwhelm websites with internet traffic, forcing them offline. Once Persirai infects, it'll also block anyone else from exploiting the same vulnerabilities on the device. Security firm Qihoo 360 has also noticed the malware and estimated finding 43,621 devices in China infected with it. Interestingly, Persirai borrows some computer code from a notorious malware known as Mirai, which has also been infecting IoT devices, such as DVRs, internet routers, and CCTV cameras, but by guessing the passwords protecting them.

How to Easily Extend System Partition in Windows 10

Normally while extending partition during Windows installation, we keep the storage space for System Partition at least close to 100GB. But, eventually the storage bar indicator turns red and you feel the need for more storage space on your drive. Well, you probably must be knowing that the inbuilt disk management utility in Windows 10 won’t let you extend your system drive. Even though you have enough unallocated space, the Extend Partition option will be greyed out.
Yes, you can manually extend system partition by backing up the logical drives and deleting them. And, thereafter extending system partition using the available space. But, that’s a tedious task and will take too much time. So, here I’d like to show you how you can easily extend system partition without doing any backup or deletion of logical partitions.

Why only passwords can't keep you safe ?

Why only passwords can't keep you safe ?
So many online accounts, so many passwords. No wonder it's tempting to turn to apps and services that promise to keep track of your passwords.But these password managers are like treasure chests for hackers. If your master password is compromised, all your accounts potentially go with it.
One such service, LastPass, says it has detected "suspicious activity." Although it says it found no evidence that individual passwords or user accounts were breached, it's advising users to change their LastPass master password.

How to check if Google is tracking you and how to stop it if it is.

To see if you have location history enabled, head to your Google Maps Timeline. In the belt below the map Google will tell you whether location history is on or off and let you enable or pause it. (You can also find this setting in the Personal info and privacy section on your Google account page. Scroll down to the Places you go area click the toggle switch to turn it off.)
Disabling location history, however, does not remove your past history. If you'd like to erase the locations Google has stored for you, click the gear icon in the lower-right corner of your Timeline map and choose Delete all Location History.
You can also delete your whereabouts for a single day or even a single stop of a single day. Choose a day from the menu in the upper-left corner of your Timeline map. You'll then see to the left of the map a list of your stops for that day. Click the trashcan icon at the top of the list to delete the location information for the entire day, or click the triple-dot button next to a stop and select Remove stop from day to delete just that location.

Check your phone's location settings:-

  •  For iOS users who want to disable Google's location reporting from your iPhone, you will need to disable Location Reporting from the Google search app or another Google app on your iPhone, such as Google Maps.
  • For the Google search app, tap on your profile pic in the upper-left corner to open Settings. Next, tap on Privacy, tap Location and Location Reporting and then choose Do not report. You could leave Location Reporting enabled but prevent Google from storing your history by tapping Location History from the Location screen and then choosing Do not store before tapping Done.
  •  On Google Maps, tap the hamburger button in the top left, tap Your timeline, tap the triple-dot button in the top right and tap Settings. Under Location settings, you can see if Location Services and Location History are turned on or off. From this page in settings, you can also delete all or a portion of your location history.
  • There is also a new item on the main Google Maps panel called Share location. It lets you temporarily share your location with specific contacts.
  • You can also see which apps are using location services on your iPhone by going to Settings > Privacy > Location Services.
  • For Android users, the process is streamlined. Go to Settings > Location > Google Location Reporting. For Location Reporting, tap the slider to turn it off.
