An overview of ransomware threats and endpoint securityApril 12, 2018 | By Comodo
Ransomware is a type of malware that threatens to erase or deny access to data once it has taken over your computer. The attacker demands ransom, usually through cryptocurrency, in order to restore your access to the files. Owing to the growing trend of ransomware attacks, enterprises and their data have become more vulnerable to cybercriminals in the recent years. Thereby, it is vital to secure corporate network endpoints through advanced endpoint protection software to evade all types of cyber attacks.
In this article, we discuss ransomware threats and essential endpoint security tools that organizations require in order to steer clear from all types of cyber threats.
How Ransomware Works
It is important to know how Ransomware takes control of your computer.
Basically, ransomware attacks arrive in the form of Phishing Emails that disguise as important files or software updates. Once the victim opens the email and downloads the content, the malware installs itself on the computer and starts running in the background without the knowledge of the user. Latest forms of ransomware malware, like NotPetya, make use of the security weak spots to attack the computers without needing to trick users.
The victimized computer files are locked and denied access using a mathematical key known only to the attacker. Usually, the victim’s screen is prompted with a message stating that their files are inaccessible and will only become accessible if the victim transfers the ransom through untraceable Bitcoin payment. In the recent years, Ransomware attacks have been targeted at corporate levels.
It is necessary to secure all the remote devices such as laptops, mobile devices and other wireless devices using endpoint security software in order to successfully prevent attacks from infiltrating your network.

- Install advanced endpoint protection software, which detects malicious programs
- Back up your files, regularly and automatically
Some of the most malicious Ransomware examples are listed below:
- WannaCry: the ransomware attack happened worldwide in May 2017. It targeted computers running Windows OS and spread autonomously from computer to computer.
- NotPetya: a Russian-directed online attack against Ukraine. The ransomware spread from computer to computer using EternalBlue.
- Locky: a ransomware released in 2016 was very active until 2017.
- TeslaCrypt: the malware that targeted gaming files was constantly reinforced by hackers during its terror reign.
- CryptoLocker: the ransomware attack happened in 2013. The malware successfully infected 500,000 computers.
