Is Your Computer Listed “For Rent”?
Summary: An invite-only underground subscription service was renting access to more than 4,100 hacked PCs acting as proxies in 75 countries, charging a one-time $150 registration fee via WebMoney or Liberty Reserve and about a dollar a day per botted system. Krebs traced listed proxies to organizations including broker/dealer The Securities Group LLC and the Kirby Pines Retirement Community in Memphis, whose IT provider said a spam bot had been removed about two weeks earlier but was unaware the network was still being exploited.
Why it matters: A single compromised machine on your network can be sold to criminals for roughly a dollar a day, and the TSG case shows a bot removed two weeks earlier did not mean the network was clean. The service's customers could filter bots by city, IP range, provider and connection speed, which is exactly the targeting that defeats rudimentary geographic checks on bank logins.
