Crypto-ransomware is becoming an increasing problem for businesses as cybercriminals are turning their attention to using these attacks to target corporate networks.
Cybercriminals are aware that this method of attack is working and are increasingly deploying it: according to a new Kaspersky Labs report on ransomware, the number of corporate users attacked with crypto-ransomware has increased by over six times with 718,000 victims in the last year compared to 131,000 during the previous 12 months.
Previously, ransomware attacks had largely ignored corporate networks, with hackers instead choosing to target home users. While home users still make up the vast majority of crypto-ransomware victims, corporate users now account for over one in ten infected.
Almost exactly half of crypto-ransomware attacks carried out between 2015 and 2016 used Teslacrypt ransomware - although the trojan is no more after it's masterkey was released to the public in May. Nonetheless, prior to that point it had infected users, encrypted their files and demanded a ransom in Bitcoin in order to release.
