The attack exposed the issue of outdated systems, because the hacker exploited an operating system vulnerability for which a patch had long existed at the time of the attack. Users were locked out and a ransom payable in Bitcoin was demanded. The attack hit one-third of all NHS hospitals in the UK, causing estimated damages of 92 million pounds. WannaCry affected 230,000 computers worldwide.

It was designed to exploit a security vulnerability in Windows that was created by the NSA and leaked by the Shadow Brokers hacker group. WannaCry was a ransomware attack that spread to over 150 countries in 2017. Locky ransomware targets file types that are often used by designers, developers, engineers and testers. This method of spreading is called phishing, and is a form of what is known as social engineering. Users fell for the email trick and installed the ransomware on their computers. Locky encrypted more than 160 file types and was spread by means of fake emails with infected attachments. Locky is ransomware that was first used for an attack in 2016 by a group of organized hackers. Next you will learn about some well-known examples that will help you identify the dangers posed by ransomware: Locky Now you know what ransomware is and the two main types. Consequently, many victims pay the ransom simply to get their files back. Crypto developers often add a countdown to their ransom demand: "If you don't pay the ransom by the deadline, all your files will be deleted." and due to the number of users who are unaware of the need for backups in the cloud or on external physical storage devices, crypto ransomware can have a devastating impact.
This spreads panic because users can see their files but cannot access them. The aim of crypto ransomware is to encrypt your important data, such as documents, pictures and videos, but not to interfere with basic computer functions. Complete destruction of your data is therefore unlikely. But there is good news: Locker malware doesn't usually target critical files it generally just wants to lock you out. Apart from that, the computer is inoperable. This allows you to continue to interact with the window containing the ransom demand in order to make the payment.
For example, you may be denied access to the desktop, while the mouse and keyboard are partially disabled. This type of malware blocks basic computer functions. In particular, two types of ransomware are very popular: Identifying ransomware – a basic distinction must be made A ransomware attack can therefore target both individuals and companies.

Attack vectors frequently used by extortion Trojans include the Remote Desktop Protocol, phishing emails, and software vulnerabilities. Victims of malware attacks have three options after an infection: they can either pay the ransom, try to remove the malware, or restart the device. In order to protect against ransomware infection, a watchful eye and security software are recommended. Cybercriminals demand ransom money from their victims in exchange for releasing the data. If a computer or network has been infected with ransomware, the ransomware blocks access to the system or encrypts its data. Ransomware is a type of malware (malicious software) used by cybercriminals.
