Ransomware attacks have more than doubled this year, as criminals turn to powerful new forms of file-locking malware and additional attack techniques to conduct campaigns that are more lucrative than ever before.
Ransomware came to the fore in 2017 because of the widespread impact of global campaigns WannaCry amd NotPetya. But shortly after that, ransomware appeared to fall out of favour with hackers, with many switching to campaigns based around cryptojacking attacks, trojan malware or credential theft.
