The biggest news was the release of the Princess Evolution RaaS and a new variant of the Dharma ransomware utilizing the .cmb extension for encrypted files. Otherwise, it was mostly small variants released that will not likely have many victims.

Remember, while ransomware is not distributed as much through malspam, it is still a threat and being installed via more sneaky methods such as through remote desktop, exploit kits, and other malware. Therefore, continue to make sure those backups are working well and to have an updated security software installed.
