ESET-LOGOBANGALORE, India – April 24, 2014: ESET, a leading provider of security solutions for businesses and consumers, has warned that Heartbleed bug causing widespread alarm on affecting more than feared and could affect billions of users like websites, internet users, and smartphone users. Heartbleed Bug is used to extract private SSL Keys and it allow Malicious Individuals to extract Information invisibly during an Encryption process. It affects the open-source encryption software OpenSSL – which is used on millions of web servers which has been undiscovered for more than two years. 
In recent past, Heartbleed bug has affected at least 500,000 sites and millions of users by the small programming error did by the student, who has spoken of his regret at the incident. Any smartphone not protected by “enterprise grade” security may be at risk due to the apps.

Heartlbeed’s ability to steal private keys raised the scope of Heartlbeed considerably. Having access to these private keys means hackers can return even after the Heartbleed exploit has been removed through the window. Hackers can only cease to have access to these keys once the server’s security certificates are all updated. It means fixing the bug may not solve the problems Heartbleed has created.
