Dealing with Wannacry Ransomeware       
By: Kartikeya Semwal

Countries all over the world got a shock in May 2017 when an unknown group of hackers attacked computers all over the world with a worm called “Wannacry Ransomeware”. It is a crypto worm that attacks computers running on Microsoft Operating System, by encrypting the data present in the computers and locks them, asking for password to unlock it. The password is present with the hackers only, who then demand money in ransome in Bitcoins in exchange of providing password to unlock the computer.

This cyber-attack took place from 12 to 15 May 2017 and infected 3,00,000 computers and 2,00,000 people across 100 countries. Its impact was huge as most of the people were using various new versions of Windows such as 7, 8.1, 10, Windows Servers 2008, 2012, 2016 and Windows Vista. “Wannacry Ransomeware” used the computers’ ‘Eternal Vulnerability’ to spread itself.  

Surprisingly, those people using older versions of Microsoft Windows such as Windows XP and Windows Server 2003 had very less effect of this ransomeware. This means that those two Windows had some kind of resistance in them against the ransomeware, which needs to be identified and rediscovered so that it can be used to make an anti-crypto wormware.
There is one more thing that can be done to prevent this kind of crypto-worm and that is- to not open any kind of suspicious or unknown page or e-mail; and prevent anyone from getting access to your computer. This can also be done by blocking the URL that carries the wormware, from dispatching its payload on the targeted computers. You can also download latest security patches released by Microsoft for all its Windows versions. Also keep your anti-virus up to date by upgrading it every month.

Indian Navy needs a variety & quantity upgrade in submarines

Image
By: Kartikeya Semwal Conventional submarine  Indian Navy is the world’s 7 th largest navy in the world with 294 warships. While our biggest enemy China is ranked 2 nd largest with 730 warships of different types. This is a cause of concern as we aren’t even half of our enemy. In the last 1 decade, under Prime Minister Shri Narendra Modi ji & Raksha mantri Shri Rajnath Singh ji, our navy has added many warships to its fleet, yet a lot more needs to be done. China has a large number of different types of submarines ranging from conventional to nuclear. The advantage that they have is that they are building their own submarines & that too, at a fast pace. Contrast to that India doesn’t makes its own conventional submarines. And there is a huge gap in this category. China has 48 conventional submarines which means that it can deploy as many of them to watch or surround Indian Ocean region (IOR) while India has only 16 conventional submarines. Those too are the old Russian Kilo cl

Those 21 Mig-29s were needed

  Those 21 Mig-29s were needed  By- Kartikeya Semwal  IAF had signed a deal with the Russian Mig Consortium to purchase 21 Mig-29s to strengthen its air-defense capabilities and increase its number of fighter squadrons. But now that deal has been canceled keeping India’s MWF/Tejas Mk-2 in mind. But one thing that IAF failed to notice is that the 1 st MWF won’t be inducted before 2026, which is far away for now and the 1 st flying squadron of MWF/Tejas Mk-2 won’t appear before 2028-2029 which is way too long keeping IAF’s requirement and Chinese threat in mind.  Mig-29 UPG of IAF Some of the defense experts and analysts have expressed concern with inducting more Russian jets as they can be hacked into and crashed by China’s cyber force. But India has the ability to counter it by installing their own system computers and indigenous radar and EWS (electronic warfare system) on those Mig-29s. Those were also meant to be upgraded in terms of hardware and software. According to me, IAF has
