KLIMAX: Pro Ling Memory Write Patterns to Detect Keystroke-Harvesting Malware
Privacy-breaching malware is an ever-growing class of malicious applications that attempt to steal confidential data and leak them to third parties. One of the most prominent activities to acquire private user information is to eavesdrop and harvest user-issued keystrokes. Despite the serious threat involved, key-logging activities are challenging to detect in the general case. From an operating system perspective, their general behavior is no different than that of legitimate applications used to implement common end-user features like custom shortcut handling and keyboard remapping. As a result, existing detection techniques that attempt to model malware behavior based on system or library calls are largely ineffective.
