What is the impact of Heartbleed virus?

What is the impact of Heartbleed? The Heartbleed bug allows anyone on the internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software.

How does the Heartbleed attack work?

The Heartbleed attack works by tricking servers into leaking information stored in their memory. So any information handled by web servers is potentially vulnerable. That includes passwords, credit card numbers, medical records, and the contents of private email or social media messages.

What type of vulnerability is Heartbleed?

The Heartbleed Bug. The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet.

How is the heartbleed bug exploited?

Heartbleed is therefore exploited by sending a malformed heartbeat request with a small payload and large length field to the vulnerable party (usually a server) in order to elicit the victim’s response, permitting attackers to read up to 64 kilobytes of the victim’s memory that was likely to have been used previously …

The Heartbleed attack takes advantage of the fact that the server can be too trusting. When someone tells it that the message has 6 characters, the server automatically sends back 6 characters in response. A malicious user can take take advantage of the server’s gullibility:

What is Heartbleed and how does it affect you?

Heartbleed is a vulnerability that came to light in April of 2014; it allowed attackers unprecedented access to sensitive information, and it was present on thousands of web servers, including those running major sites like Yahoo.

How many servers are affected by Heartbleed?

An Attacker can obtain up to 64K memory from the server or client as well that uses an OpenSSL implementation vulnerable to Heartbleed ( CVE-2014-0160 ). Researcher estimated two-thirds of the world’s servers i.e. half a million servers are affected by the Heartbleed Bug, including websites, email, and instant messaging services. 5.)

Which devices are vulnerable to Heartbleed?

IP phones, Routers, Medical devices, Smart TV sets, embedded devices and millions of other devices that rely on the OpenSSL to provide secure communications could also be vulnerable to Heartbleed bug, as it is not expected for these devices to get the updates soon from Google’s Android partners.
