It’s important to take a holistic view when thinking about security. How do you protect yourself from threats like ransomware? Bitcoin and other crypto-currencies are often used because they give the attackers anonymity and are difficult to trace. Once ransomware encrypts the user’s files it demands a payment of money-a ransom-in exchange for restoring the encrypted files. The user is then directed to a malicious website that makes them download software or a file pretending to be a legitimate document which, when opened, installs the ransomware on the user’s computer. How does ransomware work?Ī ransomware attack typically begins when a user clicks on a link or attachment in an email. When it infects a system, WannaCrypt starts encrypting local files and searches the network for other vulnerable systems it can spread to. It combines the capabilities of ransomware with behavior we typically see in a network worm. The WannaCrypt variant of ransomware is more advanced than previous versions, enabling the rapid spread of the ransomware globally. This post gives an overview of what ransomware is and explains the steps organizations can take to protect themselves against WannaCrypt and other forms of malware going forward. Known as “WannaCrypt,” this ransomware targets Windows XP systems and has impacted organizations across the globe. We have just witnessed one of the largest ransomware attacks in history.
