Webtechniques are suﬃcient to bypass most commercial and open source malware detection techniques, rendering the lack of de-obfuscation fea-tures in tools a vulnerability. This paper focuses on a speciﬁc obfuscation technique, which we call XOR(255). XOR is the exclusive-or binary operation. XOR binary op-erations are performed with “keys.” WebMost implementations of Yao’s garbled circuit approach for 2-party secure computation use the free-XOR optimization of Kolesnikov & Schneider (ICALP 2008).
