Ransomware is malware which encrypts your files until you pay a ransom to the hackers. Before beginning the encryption process, the Clop ransomware blocks over Windows processes and disables multiple Windows 10 applications, including Windows Defender and Microsoft Security Essentials — leaving you with zero chance of protecting your data.

Hackers can also use internet-based cameras and mics to spy on and communicate with people — including young children via smart baby monitors. Humans are possibly the weakest link in any security protocol. This is why cybercriminals are now turning to human psychology and deception to try and gain access to personal information.
