While we have all sorts of technologies to protect the computer systems and the data, cyber-attacks are still rampant today.

The latest to add to this list is the global ransomware attack by WannaCry or WanaCrypt0r 2.0 that has hit around 100 countries within a timeframe of 48 hours.

The attack, not only has hit hospitals, telecommunications, rail systems, and courier services but has also affected individual systems and organizations.

What is WannaCry?

WannaCry is being considered the major reason behind the attack. Also known as WanaCrypt or Wcry, it is a type of ransomware that encrypts files on the host’s system with an intention to extort money.

Using an exploit stolen from USA’s NSA (National Security Agency) the attack gave a tough time to various institutions affected. Ransomware like wcry, are finding their ways into the users’ systems through emails and SMB ports.

By encrypting the files on the system, the user is deprived access to his/her own files with a note that states, “Your files are encrypted” and “To get the key to decrypt files, you have to pay 500 USD.”

what is ransomware

This is not the only case, Hollywood Presbyterian Medical Center was also struck by a ransomware attack.

According to Wired Magazine, the entire computer system of the hospital was infected by a ransomware virus, known as Locky. As the name sounds, it locks the user out and denies decryption unless a ransom demand is fulfilled.

The IBM X-Force researchers who were continuously tracking down the trends behind such attacks noted that in 2016, the ransomware spam reached 6000%, as compared from 0.6% of spam emails in 2015 to an average of 40% of email spam in 2016. This situation is only going to worsen in 2017.

How these victims survived these attacks or what solution they got, will be discussed in the later sections of this write-up. Before we suggest some solutions, it’s important that you understand what ransomware is and how it affects your computer system.

What is Ransomware?

According to Kaspersky, “Ransomware is a type of malware that severely restricts access to a computer, device or file until a ransom is paid by the user.”

The present era is witnessing the rise of internet users, and along with it, the cybercriminals, who want to make illegal money out of this burgeoning market.

Ransomware attacks are targeted with the sole aim of making money. Attackers sabotage your personal files and computers and deny access until you pay the ransom in return, which they usually demand in bitcoins.


The horrible state of inaccessible files and computer systems, make ransomware one of the most dangerous malware of our time. The market has witnessed two common types of such viruses:

  • Encrypting Ransomware: This particular malware encrypts the user files, networks and data, and demands a decryption price or ransom, mostly in bitcoin. CryptoLocker, Locky, and CryptoWall are some of its examples.
  • Locker Ransomware: Infection by this ransomware will deny your access to the computer system. It will lock you out and will demand a ransom if you want to regain access. The common examples include “Police-themed”, ransomware and Winlocker.

While both the types are targeted at denying access to something that you want, crypto-ransomware or encrypting ransomware is particularly harmful. How?

Locker Ransomware simply locks the user interface that stops you from accessing the system. It will not allow you to log into the system.

In some cases, even the mouse and some of the keyboard functionalities are also denied. As the virus attack is on the user interface, chances are there that the underlying systems are safe, and hence the malware can be cleaned easily.

In the case of crypto-ransomware, the condition is worse. The files and data are locked or encrypted such that it may result in absolute data loss. The data can range from person to person.

For some, it may be a lost family album, while for a professional, it may be loss of an important financial report. Anything can be encrypted, be it any document, video, audio or any image. Thus, crypto-ransomware directly hits your valuable data.

So, what are the possibilities to protect your system from a ransomware attack? Or How to deal with a CryptoLocker?

How to protect your computer system from a ransomware attack?

Ransomware is definitely a serious threat to your computer system. Hence, precaution is always better than cure. If you are able to stop the virus from entering your PC, then you can rest assured of your data. But for that, you should know how you can fall victim to a ransomware attack:

  • Suspicious and spam emails are the secret paths for these intruders. You may receive some malicious emails probing you to download them. It may sound like “You have won the lucky draw, open attachment to claim your money.” Unknown email IDs and very similar-looking brand names can mislead you to download a wrong attachment and get malware installed on your system.
  • USB drives that are already infected with the virus. When you use your drives on multiple devices, most commonly on public computers, you might unknowingly invite viruses.
  • Some viruses get installed while you are downloading third party software or exchanging files on a network.
  • Following any link leading to a comprised or hacked website can also let the malware into your system from already-present malware on your systems.

Now that we know from where these malware can enter your computer systems, let’s have a look at the preventive measures.
