Sheran spends most of his time researching mobile malware, security and forensic analysis techniques. In between bouts of bricking mobile devices, Sheran comes up with occasional, mildly interesting research topics. As a change of pace, he also tried his hand at authoring a security book on Android. He wrote a fairly well-read white-paper analyzing real-world BlackBerry malware that gained him some level of notoriety. Sheran was a former co-founder and CISO for GO-JEK Indonesia.
