These techniques exist today and are discussed in Chapter 4.

To detect and stop these threats, security teams need to regain full visibility into net- work traffic, reduce the exposure of the network and user, and establish new techniques to detect and prevent modern malware. In the truest sense, modern malware consists of networked applications that are uniquely designed to evade traditional security solutions. Modern malware depends on the enterprise network in order to survive. We cover this and other botnet security challenges in the next section. A whole host of challenges make botnet takedowns very challenging, not the least of which is the need to take down the entire command-and-control infrastructure in a rela- tively short window of time. and any dissemination, distribution, or unauthorized use is strictly prohibited.Ĭhapter 2: Defining Modern Malware 25 While all that certainly sounds ominous, there is an important distinction between the way that the security industry goes about completely dismantling a botnet and the steps that an enterprise should undertake to protect itself from that same botnet. These materials are the copyright of John Wiley & Sons, Inc. TDL-4 updates and distributes information about infected machines over the Kad network, so that even if a command-and-control server is taken down, other infected bots can be found to maintain the botnet - without command-and-control servers. That’s right! You’re familiar with Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS) - get ready for Malware as a Service (MaaS)! For command and control, TDL-4 uses the Kad P2P network, a publicly accessible P2P file exchange network.

TDL-4 can also install a proxy server on an infected machine, which can then be rented out as an anonymous browsing service that proxies traffic through numerous infected machines. Very cleverly, TDL-4 actually removes approximately 20 common malware programs - such as Gbot and ZeuS - to avoid drawing unwanted attention to a victim computer when legiti- mately installed antivirus software detects these common malware programs on the computer! Communications are concealed using proprietary encryption that is tunneled within SSL. Persistence is achieved through installation of a bootkit that infects the Master Boot Record (MBR) of the victim machine, and more than 20 additional malware programs, including fake antivirus programs, adware, and a spamming bot. *Derived from analysis by Kaspersky Labs Figure 2-5: TDL-4 - the “indestructible” botnet.
