A new trojan targeting Google Android users, mostly in China, could be a sign that mobile malware is getting sophisticated in a hurry.

The trojan, dubbed Geinimi, contains botnet-like capabilities and may serve as proof that malware designed for the smartphone is evolving much faster than it did when PCs first arrived on the scene, said Kevin Mahaffey, CTO of Lookout Mobile Security, which recently discovered the malware and posted a technical analysis of it on Friday.
