The biggest news this week is the POC ransomware targeting ICS/SCADA that was demonstrated at RSA this week and the live streaming by Fabian Wosar of him reversing and cracking a new ransomware called Hermes. A new variant of the JobCrypter Ransowmare was discovered by MalwareHunter that uses new contact email addresses. 75% of all the ransomware families active during the past year were developed by a Russian-speaking coder, most likely hiding in one of the former Soviet states.
