Last summer, it was nearly impossible to avoid the news about the Stagefright vulnerability. At the time of its unveiling, security researchers believed Stagefright to be the worst Android vulnerability to be discovered. Nearly a year after its discovery, Metaphor is the most recent embodiment of the vulnerability to rear its ugly head.

Social engineering, a popular technique used to lure victims into becoming infected with malware, can also play a key role in encouraging victims to open web pages that allow the exploit to take place and for Metaphor to be fully effective.
