Anti keylogger techniques - Literature review Example The recent increase in internet usage means that that the disadvantages of key-loggers outweigh its productive uses. The source amplifies how key-loggers are a serious threat to privacy and security, especially because they are barely discernible against anti-virus and spyware applications. Transient kernel control flow attacks are an innovative group of stealthy kernel-level malware that apply dynamic soft timers to attain considerable work while evading any continual alterations to kernel code or data (Wei, Payne, Giffin, and Pu, 2008). To defend against attacks such as stealthy key logger and a CPU cycle stealer, it is essential to examine the static analysis of the entire kernel. The source affirms that through this, one can identify and catalog all genuine STIR in a database. At run-time, a reference monitor in a reliable virtual machine allows the implementation of recognized and good soft timer interrupt requests and averts implementation of all unidentified STIRs. Schiffman and Kaplan (2014) present new SMM-based malware that usurps USB host controllers to interrupt USB events. System Management Mode (SMM) in x86 can manage physical hardware that the host operating system cannot notice virtually. It is a new class of malware with unbelievable power that helps to transform kernel data structures and trapping on I/O registers to execute PS/2 key loggers. In essence, it helps SMM root kits to manage USB devices straightforwardly without while denying the OS kernel from receiving USB-related hardware interrupts. Schiffman and Kaplan also discuss a proof-of-concept USB key logger, which are harder to identify than previous SMM-based key loggers that are activated by OS actions like port I/O. The source further suggests extra extensions to this technique and processes to avoid and moderate such attacks. Gupta, Sengupta, Bhattacharyya, and Chattrejee (2009) present a user verification
