Description:Cheating in massive multiple online games (MMOGs) adversely affect the game's popularity and reputation among its users. Therefore, game developers invest large amount of efforts to detect and prevent cheats that provide an unfair advantage to cheaters over other naive users during game play. Particularly, MMOG clients share data with the server during game play. Game developers leverage this data to detect cheating. However, detecting cheats is challenging mainly due to the limited client-side information, along with unknown and complex cheating techniques. In this presentation, we aim to leverage machine learning-based models to predict cheats over encrypted game traffic during game play. Concretely, network game traffic during game play from each player can be used to determine whether a cheat is employed. A major challenge in developing such a prediction model is the availability of 12 sufficient training data, which is sparingly available in practice. Game traffic obtained from a few known players can be easily labeled. However, if such players are not a good representation of the population (i.e., other players), then a supervised model trained on labeled game traffic from these set of players may not generalize well for the population. Here, we propose a Graphics Processing Unit (GPU) based scalable transfer learning approach to overcome the constraints of limited labeled data. Our empirical evaluation on a popular MMOG demonstrates significant improvement in cheat prediction compared to other competing methods.

Description:The security of software supply chains is a topic that has been largely overlooked over the past few years, despite numerous recent incidents which show that attacks can happen at any point in this chain, including the most recent one involving SolarWinds. We have developed in-toto, a novel framework that provides insights about processes that occurred in the various steps of the software supply chain. in-toto is the first security mechanism that protects software from the point when the developer commits the code until the end user installs it. in-toto has been deployed into several real-world open source and commercial systems.
