This is a guide to keep your computer secure against the Java attack. This post is on how to remove Java from your Windows 7 PC completely to keep your computer safe against any suck attacks. There are a lot of vulnerabilities with Java and is recommended that you remove java completely to keep your computer to be secure against any java exploits. Before you uninstall , you must know that uninstalling Java from your java may not allow some programs to run properly.

Step 1:

Click on the Start Button  (that looks like a flag usually in the left bottom corner of your screen) and click on “Control Panel”.

ctrl

Step 2 :

Now, click on “Uninstall a program” . (Note: If you don’t see a similar page like the one below, try to change the View in the top to “Category” )

Step 3:

Now, type in “java” in the search box in the upper right corner. You will now see all the java components like the one below:

A group of researchers from “The University of Texas” at Austin successfully nabbed the drone on a dare from the Department of Homeland Security with parts less than $1000.

They managed to do it through spoofing, a technique where a signal from hackers pretends to be the same as one sent to the drone’s GPS.

The team warned that it is crucial that the government address this grave security concern before it goes any further with plans that would allow drones to fly over American soil.

Fujitsu Laboratories said on Monday that it has successfully cracked a next-generation cryptography standard known as pairing-based cryptography, breaking a world record.

Fujitsu and its partners, Japan’s National Institute of Information and Communications Technology (NICT) and Kyushu University, took 148.2 days to carry out a cryptanalysis of the 278-digit (923-bit) pairing-based cryptography, a task that had been thought to require several hundred thousand years.

 

The team used 21 personal computers with a total of 252 cores, which Fujitsu noted was several hundred times the computing power used to achieve the previous world record, cracking a cryptogram based on  204 digits (676 bits).

“As cryptanalytic techniques and computers become more advanced, cryptanalytic speed accelerates, and conversely, cryptographic security decreases,” Fujitsu said in a statement. “Therefore, it is important to evaluate how long the cryptographic technology can be securely used.”

“We were able to overcome this problem by making good use of various new technologies, that is, a technique optimizing parameter setting that uses computer algebra, a two dimensional search algorithm extended from the linear search, and by using our efficient programing techniques to calculate a solution of an equation from a huge number of data, as well as the parallel programming technology that maximizes computer power,” Fujitsu said in a statement.
