What is WannaCry Ransomware and How Does it Work?
WannaCry is a type of ransomware that encrypts files on a computer system, making them inaccessible to the user. It works by exploiting a vulnerability in the Windows operating system, specifically the SMBv1 protocol. Once a system is infected, WannaCry spreads rapidly to other connected devices, encrypting files and demanding a ransom in Bitcoin in exchange for the decryption key.
The WannaCry attack is particularly devastating because it can spread quickly and quietly, often going undetected until it’s too late. The ransomware also has a “kill switch” that can be activated remotely, allowing the attackers to shut down the malware and prevent further damage. However, this kill switch can also be used to reactivate the malware, making it a persistent threat to infected systems.
What Happened to Merck & Co. During the WannaCry Attack?
Merck & Co., a multinational pharmaceutical company, was one of the many organizations affected by the WannaCry ransomware attack in 2017.
