In this presentation,  I will introduce a new model-checking approach for malware detection that takes into account the behavior of the stack. Our approach consists in :
(1) Modeling the program using a PDS.
(2) Introducing two new logics, called SCTPL and SLTPL, to represent the malicious behaviors. SCTPL (resp. SLTPL) can be seen as an extension of the temporal logic CTL (resp. LTL) with variables, quantifiers, and predicates over the stack.
(3) Reducing the malware detection problem to the model-checking problem of PDSs against SCTPL/SLTPL formulas. We present symbolic techniques to solve these model-checking problems and implement them in our tool PoMMaDe. PoMMaDe was able to detect 600 real malwares and 200 new malwares. Several well-known and widely used anti-viruses such as Avira, Avast, Kaspersky, McAfee or Norton were not able to detect several of these new malwares. PoMMaDe was also able to prove that 400 real benign programs are benign.Bio:
