It sounds like a smartphone user’s worst fear: Software that starts up before the phone’s operating system, intercepting and encrypting every byte sent to or from the flash memory or the network interface.
This is not some new kind of ransomware, though. This is the D4 Secure Platform from Cog Systems.
The product grew out of custom security software the company developed for governments, and which it saw could also be put to use in the enterprise as a way to make smartphones more productive while still maintaining a high level of security.
It includes a Type 1 hypervisor, a virtualized VPN and additional storage encryption that wrap the standard Android OS in additional layers of protection largely invisible to the end user.
