More than 100 PCs of Andhra Pradesh police have likewise been influenced.

South Indian part of our country became the prey of these cyber attacks which targeted computers running Microsoft Windows operating system. Carrying out using WannaCry (malware), the attack was considered to be a ransomware. This ransomware is a digital system that locks down the systems by encoding the data on it.

With rising e-parasite attacks, it is time to take preventive measures to lessen the risks of these Cyber Attacks.

1) Using passwords that are difficult to access:

Your passwords must be easy to remember but difficult to assume by any third person. Don’t just use letters or numerical. Use a combination of these to make the password more complex which reduces the chances of your data getting hacked. For example instead of 12345 or abcde, one can write a2b3c1d4. Usage of signs and symbols along with the password makes them stronger.

2) Lock your phone and laptop:

Make sure you always have a preferable lock in your laptop and mobile phone. By chance, if your phone or laptop is lost, so that no other random person can access it the usage of locking system is preferred. Facilities such as remote tracking and remote wiping are much helpful in this case.

3) Change your Wi-Fi password:

Change the default password that your Wi-Fi router came with. This is the password that even the Wi-Fi setter knows. Well, this is risky. So, think of it and put a new password for your Wi-Fi connection.

4) Be aware of the social networking sites:

Nowadays, even the social networking sites get hacked. Enter no personal and confidential information in these sites.

5) Different service, different password:

Use different passwords for various services. Same password for every multiple service results in less security. Hence, it is risky. This implies that if a programmer has one secret word, he or she has the greater part of your passwords.

6) No random hard drives allowed:

Do not use pen drives and hard drives which you don’t trust. Don’t put your computer at risk if the source is unknown. You never know, which hard drive is made with an intention of stealing your data present in your system.

7) Be careful while installing apps:

Read all the permissions before installing any app rather than avoiding them. You should be aware of the permissions the apps are taking from your cell phones. They might be accessing your personal information like contacts, location or your phone’s camera, which leads to encouragement of Cyber Attacks.

8) Use a secure website:

There is a need to ensure that the website is secure before you enter any of your confidential information in them. Check that the web address of that website starts with “//”. This proves that the website is totally secure.

To conclude, Cyber Attacks now are constantly increasing at a rapid pace which is alarming for the whole nation. Hence, these preventive measures can be a turning point to make strong gateways of our online accounts and websites.
