Although Linux holds only a small market share, Linux computers appear to send a disproportionate amount of spam compared to other operating systems, according to new research from Symantec's MessageLabs messaging security division.
Symantec looked at spam from November 2009 through March and broke down what kind of operating system is on the computer that sent the spam. Analysts do that by a method called passive fingerprinting, which involves analyzing the network traffic of a remote host, which reveals that host's operating system.
Since Windows holds more than 90 percent of the market, the lion's share of spam still comes from Windows machines, said Paul Wood, a MessageLabs intelligence analyst with Symantec.
