Even
if you read a little about tech news, I doubt you may not have not heard the
name Heartbleed bug. It has shaken the internet geeks! But what is this buzz
all about?
What
is a Heartbleed?
Heartbleed
bug is a serious vulnerability in one of the implementation of SSL/TLS
cryptography protocol which is OpenSSL. The scary thing is, OpenSSL is used by
the 2/3 of the websites on the internet. And this bug went undetected for 2
years.
How
serious is this bug?
Quoting
the security expert Bruce Schneier,
"Catastrophic" is the right word. On the scale of 1 to
10, this is an 11.
What
is the risk?
This
security bug can allow attacker to read arbitrary 64kb chunk of server memory.
The vulnerability lets a hacker
access up to 64 kilobytes of server memory, but perform the attack over and
over again to get lots of information. This allows
the tracking the username, passwords and cookies. The Heartbleed bug is putting millions of passwords and credit
card numbers at risk.
What
can I do to make sure I am secure?
If
you have access to server, you will need to install latest OpenSSL patch. If
you are just a user, you can do nothing until website / web server
administrator has fixed the issue. Once the issue is fixed at sites, we
recommend you to change your passwords ASAP. To check if the issues is fixed
on aparticular site, check : http://filippo.io/Heartbleed/ .
How
do I know if I am not compromised?
Unfortunately,
exploitation of this bug leaves no traces of anything abnormal happening to the
logs as said on heartbleed.org . You won't find any abnormality in your log if
you've been compromised.
Which
famous sites were affected by this bug?

Irrespective of receiving daily oral or future injectable depot therapies, these require health care visits for medication and monitoring of safety and response. If patients are treated early enough, before a lot of immune system damage has occurred, life expectancy is close to normal, as long as they remain on successful treatment. However, when patients stop therapy, virus rebounds to high levels in most patients, sometimes associated with severe illness because i have gone through this and even an increased risk of death. The aim of “cure”is ongoing but i still do believe my government made millions of ARV drugs instead of finding a cure. for ongoing therapy and monitoring. ARV alone cannot cure HIV as among the cells that are infected are very long-living CD4 memory cells and possibly other cells that act as long-term reservoirs. HIV can hide in these cells without being detected by the body’s immune system. Therefore even when ART completely blocks subsequent rounds of infection of cells, reservoirs that have been infected before therapy initiation persist and from these reservoirs HIV rebounds if therapy is stopped. “Cure” could either mean an eradication cure, which means to completely rid the body of reservoir virus or a functional HIV cure, where HIV may remain in reservoir cells but rebound to high levels is prevented after therapy interruption.Dr Itua Herbal Medicine makes me believes there is a hope for people suffering from,Parkinson's disease,Schizophrenia,Cancer,Scoliosis,Fibromyalgia,Fluoroquinolone Toxicity
