Help me identify an App by the icon on Notifications

[zinksilver]

Hi,

I've searched on the entire Google and even on Q&A websites, I can't seem to find what this app is.

This is a device I can't unlock or expand the Notification shade/bar, but all I want is to know:

What is this Devil-like app icon? Does anyone know what App is this?

"Devil-like"? I've never seen it before, but it's probably from an app. Kill apps one at a time (use SystemPanelLite) until it disappears.
