Post an informed answer: There is also a service that tests whether the Web site is affected: Test your server for Heartbleed (cve-2014-0160) (now long 503) According to the description on the page, this OpenSSL implementation vulnerability can obtain the sensitive memory data on the host in the handshake phase, even including the SSL certificate private key! The loophole appeared in 2012 and was only recently repaired yesterday (April 7, 2014). To

According to foreign media reports, network security experts warned on Wednesday that a frequently used segment ldquo; Bash rdquo; in open-source software Linux has recently discovered a security vulnerability, its threat to computer users may be more than the ldquo; Heartbleed rdquo; (Heartbleed) vulnerability exposed in April this year. Bash is a software used to control Linux computer command prompts

On the heartbleed official website, detailed information about the CVE-2014-0160 vulnerability, this is about the OpenSSL Information Leakage vulnerability caused by security issues. Changing the Heartbleed bug allows anyone on the Internet to read system-protected memory. This compromise key is used to identify service providers and encrypted traffic, user names and passwords, and actual content. This vuln

The Heartbleed problem is actually worse than it can be seen now (it seems to be broken now ). Heartbleed (CVE-2014-0160) is an OpenSSL vulnerability that allows any remote user to dump some of the server's memory. Yes, it's really bad. It is worth noting that a skilled user can use it to dump the RSA private key used by the server to communicate with the customer through a process. The level of knowledge/s

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/SSL-HEARTBLEED.HTMLNMAP-SV--script=ssl-

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' privacy information transmitted over the Internet. After the website uses this encryption

First of all, my name is called Transport Layer Security Protocol (Transport Layer Secure Protocol), which is an upgraded version of SSL. In fact, my left and right hand are able to use the left hand is called record layer (record), the right hand is called handshake layer (handshake layer) ...Me: Hey, wait a minute, record layer? The handshake layer? What the hell is all this?

Local thread storage TLS The local variables defined in the stack are safe for multithreading because different threads have their own stacks. Generally, the defined global variables can be read and written by all threads, so that they are not thread-safe. to ensure security, it is necessary to lock mutex access. What is Thread Local Storage (TLS), simply put, is a variable (usually a pointer pointing to a

Recently, the openssl (heartbleed) vulnerability is quite popular. It seems that some people on Weibo have said there are not many dangers in the past few days. However, according to the test, it is found that the damage is still relatively large. So I found a site and used a for loop to capture 100 files in batches. It took about 10 minutes to complete the process. There were about 10 accounts and passwords to search for. Basically, I could log on to

Search openssl heatbleed 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 code for manual updates without the need to
