Fear of dangerous cyber attacks

With the possibility of microprocessor error, 'meltdown' and 'speaker', the cyber attacks, have been threatened with almost all of the world's desktops, laptops, tablet computers, smartphones and other devices. There is no common anti-virus or computer security software that can attack such attacks. Users can not easily understand whether they are being trafficked with the information, whether it is being trafficked with the information.

In the event of Meltdown Processors, in memory of the bug, the RAM can enter and pass through all the passwords and information from the operating system. The Spectator can make itself a program to read and steal other software information through one software.

The new cyber attack has been known for three to four days. In the meantime, Microsoft Corporation, Apple Computer, Google and other major technology organizations have updated their operating system so that the attack can keep the computer and mobile phone secure.

These bugs or bugs were made in all Intel processors created after 1995. This error has been detected by Advanced Micro Devices (AMD), Advanced Risk Machine (ARM) and Qualcomm made processors. This error also occurs in the GPU (Graphics Processing Unit) used on the computer's graphics card.

The meltdown and the speaker are the cyber attacks that have taken the chance of hardware (hardware) errors - this is how Raghib Hasan, associate professor and computer security expert of Computer Science at the University of Alabama at Birmingham, USA. He explained why this cyber attack was created. To increase the computer performance, all processor makers use a technical technique. For three to four decades, this technique, called spacquel execution, is being used in microprocessors. This means that the processor processes some information beforehand by understanding the type of user's operating system through the operating system or different software. This leads to the speed of its work. The bug remained the same in this strategy.

Intel Corp., the world's largest microprocessor maker, has made all the processors since 1995, all of which have this error. Since 2013, Intel has made the Atom processor for tablets computer, Intel has made these errors. Apple Computer has become a processor from Intel. As a result, almost all of the world's computers, smartphones are at risk of this cyber attack.

International media on The Meltdown says The Guardian, it is the worst among the recent CPU (Central Processing Unit) faults. A few months ago, Intel could know about this error of the processor. In a news story of Fortune magazine, after knowing this information, Intel has sold half of its shares in Intel for months, and its chief executive officer Brian Krizeneck As a result, the importance of understanding the importance of the matter is not left.

There is no clear information about how much cyber attack and data has been stolen using Meltdown and Spectator. The UK's National Cyber ​​Security Center says there is no evidence of theft of information by Meltdown and Spectator. However, it is very difficult to identify the attack in this attack.

The process that is performed on the computer or the direction that it gets, is stored in memory before the processor. With the processor error, the meltdown can take RAM and other information through the operating system. Ragib Hasan said, the programs that were run on computers were kept separately in memory. One program can not read other information. The speaker broke the separation system. As a result, a program can get information from another program. The deadly thing is that it is not difficult to write the program to steal the data from the processor's error. There is no evidence to steal information.

Since all Intel and other processors are being used in all the computers, smartphones in Bangladesh, so all users are at risk of data theft. Risks are the servers used in the cloud computing service.

What is the dangerous way to escape from this cyber attack? Ragib said, all the operating system manufacturers have released the patches to prevent this cyber attack. The operator who is using the operating system has to update it. However, after installing this update, the speed of working on desktops, laptops, tablet computers, mobile phones, etc. is reduced by 3 to 4 percent. Meltdown can not hit AMD processors, but the speaker works.
