Researchers Kneecap ‘Pushdo’ Spam Botnet
Summary: Researchers at LastLine Inc. identified 30 Internet servers controlling the Pushdo/Cutwail spam botnet across eight hosting providers and worked with the providers to take down nearly 20 of them, according to M86 Security Labs. Pushdo had been responsible for more than 10 percent of all junk e-mail worldwide before its output tapered off over the past few days, though several command-and-control servers remain online because not all providers were responsive.
What you should know: The takedown left several control servers running, and Pushdo has rebounded from similar infrastructure attacks before - the Lethic botnet began recovering a month after its own control servers were targeted in January 2010.
