The Rise of Heartbleed

In April 2014, the revelation of Heartbleed flaw in OpenSSL program was a major story because of the very nature of the vulnerability. The bug allowed cyber criminals to intercept encrypted information affecting a large size of the population. Personal information such as usernames, passwords, credit/debit card details, and other sensitive data were compromised by Heartbleed.

Around 500,000 sites use OpenSSL to allow users to have secure interactions. Some of the big names include Google, Yahoo, Wikipedia, Facebook, and YouTube. Further, the exploit went unnoticed for two years.

OpenSSL’s open source nature made it available for free to corporates that wanted a dignified and an easy way to allow users of their websites to conduct encrypted interactions with the websites.

Moreover, the program was primarily designed by volunteer coders. Security experts suggested users to change their passwords or cancel online accounts if they felt they were vulnerable.

Precautionary Steps

  • About 48 percent of Web users with college education either changed their password or deleted an online account.
  • Around 31 percent of users with high-school education or less and 40 percent of those who attended some college did the same.

  • About 84 percent of African Americans using the Web feel more confident about the safety of their online accounts.
  • Around 55 percent Hispanics are not so confident about the same, while 70 percent of the Whites who use the Web fall in the middle.
