Ransomware, the most fear-provoking demon of the cyber world (currently), has purposefully attacked thousands of systems of the technologically advanced countries like UK, Russia, China, Taiwan, etc. The name of this global ransomware is WannsCry which have attacked and is attacking the systems running on Windows Operating System. This very recent attack is the World’s biggest ransomware attack. In this article, I’ll tell about the facts regarding Ransomware and how to protect our system from the ransomware attacks.
Ransomware is basically a malevolent software which attacks the system (smartphone / computer / tablet), subsequently, encrypts the files (stored in victimized system), locks the system and, finally, demands an amount (in the form of Bitcoins) as ransom to unlock the system.
Whenever a ransomware manages to influence (successfully) a system, a prompt message starts appearing on the screen of the system in which the ransomware demands an amount (in the form of bitcoins) to be paid within three days, in order to regain the encrypted files. The window showing the prompt message also holds a countdown timer at its left side and, further, adds that, if the did not pay the demanded amount of bitcoins within three days then the ransom will be doubled and if the user fails to do the payment within 7 days then all of the files will be done deleted forever.
How to Protect Our System From Ransomware ?
- First of all, disable the SMB service on the system by following Settings > Uncheck the settings > OK. In Windows’ system, the SMB remains enabled by default.
- Install a reliably purposeful anti-ransomware (along with a competent anti-virus) to strengthen the security.
- Mandatorily, block the ports viz. port 139, port 445 and port 3389 in the firewall.
- Fortify the system immediately with Windows security patch MS17-010.
- Take the backup of your files regularly.
- Don’t click on the link from the unknown people.
- Don’t open those emails or attachments which are sent by such firms with which you don’t do any sort of business.
- Pull Window NT4, Windows 2000 and Windows XP – 2003 out of the office premises.
- Always, keep your software updated.
- Make the Pop-up Blocker run on the Browser of the system.
NOTE : Ransomware can only encrypt the files which are stored in the computer or system. Therefore, the best and
the most preferable
precaution is to keep the thorough backup of the files. If the system gets conquered by any ransomware and the user has
backup of the files then the user can simply need to Reset his system, reinstall the software and recover the data from the backup.
