Malware uses Google Docs to communicate with control hub

A new iteration of backdoor trojan Makadocs is capable of hiding its command-and-control (C&C) server communications by abusing a legitimate Google Docs function.

Symantec researchers discovered that the malware used Google Docs, a document sharing and editing service, as a proxy server, or intermediary step, to pass along information to C&C servers, according to a Friday blog post.
