Botnet evolution

Source: The Register

The Register has a summary of new trends in botnet technology as reported by various researchers. One particularly stealthy botnet dubbed "MayDay" allegedly uses the HTTP proxy settings of the host as one communications channel, and coded ICMP messages as another. A different botnet called "Mega-D" employs spamming techniques designed to thwart greylisting, which the researchers say is the first time such a capability has been observed in the wild.
