[Questionnaire] We are writing here to get some insights from dedicated malware analysis experts. We are a group of experienced researchers, and we developed a state-of-the-art sandbox for Android malware. We are absolutely convinced that it makes sense to bring this technology to the market, but we need to picture your biggest sandbox needs in your daily work. The idea is to grasp what are, in your eyes, the must-haves of a sandbox. Our goal is to shape the product accordingly and make it available in the forthcoming months/next few months. To this end, we prepared a quick (approximately 15-minutes) questionnaire, and it would really mean a lot to us if you could share your valuable feedback. Thanks to this, we hope to offer you soon a gain of efficiency, time and energy in your job. Questionnaire: https://forms.gle/qJ9ck8UH5WQK6jAZ8
