Interlock Ransomware

Discovered in mid-2019, InterLock Ransomware has emerged as a sinister cyber threat. The risk factor surrounding this ransomware variant remains high, especially for Windows users. In March 2020, it struck more than 50 school districts in the US causing long-term damage. Another high-profile incident took place in the same month when it breached the network of Human Rights Watch disrupting their work. Given these incidents, it is clear that any entity is a potential target of this ransomware.
