Ransomware is growing fast and could become more difficult to tackle as the criminal ecosystem shifts from a few dominant players to many smaller ones.
Tech security company Bitdefender analysed Windows security threats including ransomware, coin miners, fileless malware, PUAs ('potentially unwanted applications' that can compromise privacy or security), exploits (attacks based on unpatched or previously-unknown vulnerabilities) and banking Trojans.
Bitdefender found that of all these threats, ransomware reports saw the biggest year-on-year increase – 74.2%. Ransomware also ranked first in terms of the total number of reports.
Crypto-locking malware attacks are growing, and could become more dangerous after the apparent departure of a big player.
