NamesHermes
CategoryMalware
TypeRansomware
Description(Malwarebytes) The ransomware copies itself into %TEMP% under the name svchosta.exe and redeploys itself from that location. The initial sample is then deleted.

The ransomware is not particularly stealthy—some windows pop up during its run. For example, we are asked to run a batch script with administrator privileges.

The authors didn’t bother to deploy any UAC bypass technique, relying only on social engineering for this. The pop-up is deployed in a loop, and by this way it tries to force the user into accepting it. But even if we don’t let the batch script be deployed, the main executable proceeds with encryption.
