How to prevent the next heartbleed Vulnerability
I. Introduction
Open SSL-based heartbleed vulnerability is considered a serious problem of CVE-2014-0160, OpenSSL is widely used in SSL and TLS plug-ins. This article explains how the heartbleed vulnerability was exploited.
Th
Earlier this week, a large security vulnerability called Heartbleed emerged. This vulnerability allows intruders to trick servers into leaking your personal data.
The risk of a "heartbleed" vulnerability is that it lurks deeper than a common application because it can be easily solved by upgrading the application.
Services that send security information from websites such as Gmail and Facebook may be affect

According to the Re/code website, the Heartbleed vulnerability that shocked the entire Internet world last week has aroused panic. However, the latest report shows that most websites have been updated to fix this vulnerability. Internet Security Company Sucuri conducted a systematic scan of 1 million websites. The results showed that most of the top 1000 websites with traffic are secure and they have been upgraded, and re-created authentication and pa
This article mainly introduces a Python script for detecting the OpenSSL Heartbleed vulnerability. the Heartbleed vulnerability is an earthquake on the Internet, and some people who have seen it quickly upgrade OpenSSL to avoid hacker intrusion.
What is SSL?
SSL is a popular encryption technology that protects users'
Theoretically, this vulnerability allows hackers to intercept communications between Android devices and Wi-Fi routers. We already know that the Android 4.1.1 device is affected by the Heartbleed, but grania claims that iOS and OSX devices may also be attacked by Cupid.
It is unclear how many devices are affected, but the impact is greater than that of Heartbleed. The most vulnerable is the EAP-based route
Transferred from: http://www.lijiejie.com/openssl-heartbleed-attack/ The openness and prevalence of the OpenSSL Heartbleed vulnerability has excited a lot of people and made others panic. From the point of view of attack, I already know that the online scanning tools are: 1. Nmap Script SSL-HEARTBLEED.NSE:HTTP://NMAP.ORG/NSEDOC/SCRIPTS/
This article is published by Tom Simonite on the TechnologyReview website in the article titled "connecting Devices Will Never Be Patched to Fix the Heartbleed Bug, this article describes the OpenSSL vulnerability and mentions that many online devices may never be able to fix this vulnerability because of the lack of necessary security management and software updates, which does not seem to cause Weihai, however, there are very high security risks.

The high-risk OpenSSL vulnerability Heartbleed published in April 7 has become the leading news of IT security for two consecutive weeks. Now IT experts are arguing about the impact of the vulnerability and the cost of fixing the vulnerability: To fix the vulnerability, many enterprises and projects need to extract manpower to build and pack patches, implement patches, scan risky servers and devices, and reset the Administrator and user password, you
Search OpenSSL Heartbleed on the Internet to view tens of thousands of related content. Not only is online banking affected, but many security links encrypted through OpenSSL have certain risks. Therefore, it is best to upgrade all its OpenSSL as soon as possible.For example, the OpenSSL version of The RedHat system is 0.9.8, and non-registered users cannot automatically upgrade to the latest version 1.0.1g through yum.However, we can use the source c

"Before the patch is released, it is impossible for us to publish the message first. This will only cause panic, because before the patch is released, users do not understand how to protect themselves. Doing that violates our intention ." Said Chartier.
Finally, on Monday afternoon, Heartbleed.com was launched, and people suddenly rushed in and the media followed up with reports. Basically all mainstream media, from CNN to The Washington Post to New York, have reported the OpenSSL vulnerabilit

The Heartbleed vulnerability is still not fixed on more than 0.3 million servers.
Message name from neowin:
Unfortunately, this huge security vulnerability seems to have been forgotten too quickly. According to the latest report from Errata Security blog, more than 0.3 million servers are still using the affected OpenSSL version, which completely exposes the server to the Heartbleed vulnerability.
By s
means that more hackers will use it to cause a more serious security crisis.
"Using this vulnerability, attackers may take over the entire operating system of a computer, access confidential information, and modify the system. Any computer system that uses Bash must be immediately patched ."
Experts suggest that qualified enterprise users can disconnect unnecessary servers to prevent them from being attacked by the Bash vulnerability until the vulnerability is fixed.
