Embodiments described herein enable the detection, analysis and signature determination of obfuscated malicious code. Such malicious code comprises a deobfuscation portion that deobfuscates the obfuscated portion during runtime to generate deobfuscated malicious code. The techniques described herein deterministically detect and suspend the deobfuscated malicious code when it attempts to access memory resources that have been morphed in accordance with embodiments described herein. This advantageously enables the deobfuscated malicious code to be suspended at its initial phase. By doing so, the malicious code is not given the opportunity to delete its traces in memory regions it accesses, thereby enabling the automated exploration of such memory regions to locate and extract runtime memory characteristics associated with the malicious code. Such characteristics may be analyzed to automatically determine indicators of compromise, which can be used as signatures of the malicious code for subsequent runtime detection of malicious code.
