We all are not as much as aware of ransomware attacks as we should be because these may cause serious problems for you and your business.

Such malware attacks can cost you a lot of time and money along with your reputation. In our daily lives, most of the files we store on our hard drives are not as important as that we can go to any extent of paying money to get our data back.

However, this scenario is just the opposite for the corporate world. The data of the corporate businesses are the lifeline of their business empire. If this data is somehow compromised, it can cause serious damage to the organization.

So in this post, we’ll learn a few things about ransomware, how it can affect your system, and how to prevent it from happening in the first place-

What exactly is ransomware?

Ransomware is a kind of malware or malicious software designed to block access to your computer for the money. Recently attacking cyber world that encrypts your file and attacker demands a ransom (a sum of money demanded or paid for the release of a captive) to decrypt your files.

In this way, the owner loses access to his files, however, the files remain present on the owner system but it’s not readable, the encryption process transforms the contents of files to some other unreadable, jumbled data.

Types of Ransomware

According to Symantec (A global leader in Cyber Security), there are basically two major types of ransomware that we mostly come across.
1. Lockers Ransomware
2. Crypto Ransomware

1. Lockers Ransomware

These viruses generally don’t let you log in to your computer or mobile device, even they overlay your web browser and display a message like you have done some crime, that’s why you have been blocked from accessing the internet or your PC or mobile device. And to unlock the screen they demand some money.

In these tests, user files remain untouched, but this totally depends on the attacker and how they have designed the malware.

These messages seem legitimate and it’s challenging for the common people to understand what has gone wrong. Some people indeed fall into this trap and pay the ransom. Look at the screenshot-

2. Crypton Ransomware

These kinds of attacks will encrypt your user files as well as system files. Encrypting system files may result in Showing lock screens during the boot of your OS and when user files are encrypted whenever you try to open that file it will generally display a message to pay ransom to get the decryption key.

The Appearance of Ransomware Attack

The first ransomware appeared in 1989, according to Becker’s Hospital Review, an AIDS researcher Joseph Popp, distributed the floppies to other AIDS researcher saying that it contains computer application related to their research field (AIDS).

That program was ransomware. But that first attack was fundamental and later it sets the evolution of sophisticated attacks.

Recent Ransomware cases:

1. Cryptowall: This ransomware mainly targeted the US individuals and business, with lots of total $18 M. –Claims Journal

2. Tesla Crypt (2015): Loss of total worth around $70 K

3. Petya (2017): This virus seemed to be ransomware but recent research by Kaspersky labs on Petya reveals that it is a wiper. The key generated on the victim’s computer after encryption seems to be random gibberish as said by Kaspersky labs.

So, if you are infected don’t pay the ransom.

Prevention of Ransomware Attacks

My best advice is to prevent yourself from downloading an email attachment and opening unknown emails if it looks suspicious and you don’t know the sender. Like Offer emails, cash prizes, etc.

1. Use Genuine and well-known websites to download legit software.
2. Use antivirus, and keep it up to date
3. If you are suspicious about running exe or any program or opening a document update your antivirus program first, yes! Manually.
4. If you have some important files, then do not forget to backup them to another storage or cloud.
5. If you are a technical person, keep track of your Hard Drive usage led. if it’s never idle and continuously busy for hours, there might be some malicious things going on, but it’s not always the case.
