Ransomware: are we safe yet?

The digital world all around the world shook because of the Wannacry ransomware attack which targeted the computers running on the Microsoft operating System. It encrypted the system data and demanded ransom payments in the form of Bitcoin currency.

The landmine attack done by the Wannacry ransomware cryptoworm has infected more than 230,000 computers spanning over 150 nations. This virus infects all the unpatched up systems across the local networks and the internet and disable their function, locking their precious data.

And unfortunately, India is one of the worst hit nations along with Russia, Taiwan and Ukraine. According to one of the leading antivirus software manufacturer, Quickheal Technologies Ltd, in just 6 days more than 48,000 attack attempts have been made to Indian systems, Kolkata taking the worst blows of all the cities.

The cyber criminals chose to target the essential infrastructures such as hospitals, universities, blue chip companies and businesses like movie theatres. And latest among the worst hit by the malicious Wannacry ransomware virus are over 30 systems of the one of richest Hindu temples of the world Tirumala Tirupati Devasthanams.¬† Even the Andhra Pradesh secretariat wasn’t left untouched with at least 20 systems being targeted by the virus. Fortunately the systems were isolated just on time before the virus spread to other computers and the data is being retrieved. The cyber security agency of India, CERT-In has issued critical alert with respect to the Wannacry attack and have urged the affected users not to pay any ransom as there is no assurance that their data will still be unlocked by the criminals.

As we can see that the ransomware is still far from stopping in making the whole world cry over their inaccessible data, it would be wise for us to protect ourselves from the biggest malicious attack in the internet history.

Update your system software

It is believed that Wannacry virus spread to different computers as they were not updated to the latest version of the Microsoft Windows Software. You can protect your system and data from getting locked by simply installing the latest software update available.

 Install antivirus

Most of the antivirus softwares were able to detect and block the virus from infecting the computer. Installing this security barrier would help you detect and block the ransomware.

Do not open suspicious emails and pop-ups

It is believed by the experts that the malware first appeared as an email attachment and when open it spread to the connected systems. So avoid clicking the links attached with the suspicious emails coming from unknown senders. Activate the block pop-up option and do not click on anything that appears on these pop-ups as it might be another path of the virus attack.

Always create a backup of your data

Even when you might have taken all the precautionary measures, your system might still be vulnerable to the attack by the data hijackers. It is advisable to you to make a backup of your data and store in hard disk, pen drive or CDs.
