In 2017, we saw digital extortion increasingly become cybercriminals’ first and foremost money-making modus operandi. It’s mostly due to ransomware — cybercriminals’ currently most popular weapon of choice, helping them in extorting cash from users all over the world and in hitting big businesses and organizations.

On June 10, South Korean web hosting company NAYANA was hit by Erebus ransomware (detected by Trend Micro as RANSOM_ELFEREBUS.A), infecting 153 Linux servers and over 3,400 business websites the company hosts.
