The OpenSSL Heartbleed vulnerability “allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read” [1]. Heartbleed surprised the public by allowing attackers to steal sensitive information from vulnerable websites by sending crafted SSL heartbeat messages. However, due to the fact that servers can send heartbeats to clients as well, malicious servers can, in turn, attack vulnerable clients and steal sensitive information. For the Android platform, we find that roughly 150M downloads of Android apps contain OpenSSL libraries vulnerable to Heartbleed.
