His work focuses on innovative techniques for emulating microprocessor instructions and evaluating malware signatures.

Latest Patents

One of Costin Ionescu's latest patents is titled "Techniques for Emulating Microprocessor Instructions." This patent describes computer-implemented systems, methods, and media that facilitate the emulation of microprocessor instructions. The systems can identify an instruction from a first software application using a second software application that emulates the instructions of a specific type of microprocessor. The process involves adding an additional bit to the length of an operation code to create an extended operation code, which is then represented in an operation code table of the second software application. The execution of the instruction is emulated using the second software application and the extended operation code.

Another significant patent is the "Method and System for Metadata Driven Testing of Malware Signatures." This patent outlines techniques for assessing the effectiveness of a malware signature. A query tool translates a markup language malware signature definition into a database query. This query is executed against a database of application features to identify software packages that the signature would classify as malware. The results are then compared with threat information stored in the database, allowing for the classification of true/false positives and true/false negatives.
