Pentera Labs introduced DevalScript, a lightweight scripting language built on the concept of double-evaluation to streamline remote interactions with reflectively loaded DLLs. Instead of sending multiple memory operation commands across the network, DevalScript chains them together, reducing latency and enabling complex logic execution. It supports dynamic arguments, variables, contexts, conditional branching, slicing, and advanced commands like loadlibrary and getprocaddress. Use cases include loading python.dll to run scripts and creating partial functions to encapsulate reusable logic. Encodings like base128 help manage protocol efficiency. The framework improves performance, enables malware evasion, and highlights the need for proactive defenses.
