VirusTotal[1] and hybrid-analysis[2] info via [3].
It seems to be a very clearly targeted payload, named CrunchyViewer.exe. It could be served through a DNS hijack of some sort[8]. It's a modified version of Taiga[4], making it seem like a legitimate application and flying under many anti-malware programs' radars.
Apparently the exact malware strain is currently unknown. Most likely it is ransomware that activates on reboot[5]. Given there are traces of a command and control server[2] and the Lilith open source RAT[6], the ransomware payload may be supplied by the CnC server.
An overview can also be found at [7].
