Ransomware is becoming an easy source of making money for cybercriminals resulting an increase in the number of ransomware attacks recently. Such attacks are easy to launch as it does not need you to be master when it comes to codes. Malicious codes can easily be downloaded via dark communities online which patronize such hackers. Hackers generally target organizations and firms that are ill-equipped or have loopholes in their network security. Hackers normally demand ransom in the form of cryptocurrency which makes it all the more difficult to trace them if you were to track the money transactions.
Small or medium-sized organizations are soft targets for such hackers due to lack of a defense against such potential attacks. This can be improved with organizations paying more attention to protecting their network and prioritizing their resources. There has been an instance where not just businesses but even government offices, banks and hospitals have been victims of such ransomware attacks. It becomes a matter of saving one’s pride as no organization will like to gain media attention for the wrong reasons. On the other hand, such ransomware attacks result in customers loss of trust when it comes to the organization’s ability to secure their personal details. This loss of trust might result in loss of revenue and profit for such organizations.

How Ransomware Works?
The most commonly used method used to launch a ransomware attack is phishing. Here the victims are sent an email making them believe its from some reliable or trustworthy source. Once these email contents are downloaded and accessed the attackers can take control of your computer.
Ransomware can also be delivered via attacks known as drive-by download attacks on compromised or malicious websites. While some other types of ransomware can be sent using social media messaging platforms, where it can be spread via chat messages or removable USB drives.
Some other advanced forms of ransomware like NotPetya can exploit security loopholes and infect computers without having to trick users.
As we already discussed there are a number of things cybercriminals can demand once they have control of your computer. Once your data is encrypted by the cybercriminals you can only be able to access if you are able to decrypt it or end up paying for the ransom money in the form of Bitcoin to the attacker. Once payment is transferred the attacker release the mathematical key known only by them, which will help the victim decrypted compromised data.
In recent years we also have witnessed incidents where the attackers have posted to be law enforcement agency person and shutting down on victim’s computer on the pretext that they are watching illegal porn or using a pirated software. Ransom is demanded and systems are locked until the payment is made. Yet the attacks are more common their days where the attackers simply use different variations of ransomware like leakware or doxware. In such attacks, they simply threaten the victims to publicize sensitive data on the victim’s computer unless a ransom is paid.
