We develop new techniques to map botnet membership using traces of spam email. To group bots into botnets we look for multiple bots participating in the same spam email campaign. We have applied our technique against a trace of spam email from Hotmail Web mail services. In this trace, we have successfully identified hundreds of botnets. We present new findings about botnet sizes and behavior while also confirming other researcher\u2019s observations derived by different methods [1, 15].<\/p>\n","protected":false},"excerpt":{"rendered":"
