New data from Pew indicates that while many have heard of Heartbleed, less than half of those Internet users have taken steps to protect themselves.
OpenSSL is widely used on servers and embedded devices including mobile phones, giving the Heartbleed vulnerability significant global impact. According to the Pew study of 1,501 American adults, surveyed between April 23-27, 64 percent of surveyed Internet users had heard about the Heartbleed flaw.
Of those respondents who were aware of the Heartbleed flaw, only 39 percent actually took steps to protect themselves. Those steps include changing passwords and avoiding potentially vulnerable online services.
