Necurs. P2P: A New Type of peer-to-peer network Last week, I received a botnet analysis sample from a security researcher who thought it was a point-to-point peer-to-peer network, but after I analyzed it for a few days, I can determine that this network is not only a P2P network, but also a very active peer-to-peer network system. The person who provided me the analysis sample is a good friend of mine. He is also a security researcher, R136a1. (He no

Shellshock vulnerability review and analysis test 0x00 vulnerability Overview Many may have a deep memory of the Heartbleed Bug in the first half of 2014. In September 2014, another "destruction-level" vulnerability-Bash software security vulnerability emerged. This vulnerability was discovered by Stéphane Chazelas, a French GNU/Linux enthusiast.

There are already thousands of internet-connected home routers that have been infected by malware and are being used by hackers to publish distributed denial of service (dd0s) attacks. Router-based botnet investigators found that the botnet had already DDoS attacks on dozens of sites at the end of last year. The researchers traced the malicious traffic to Liu Xiang's router and operator network, discovering

Anti-DDoS (distributed denial of service) attack system is to maintain the stability of the business system, continuous operation and high availability of network bandwidth to provide protection capabilities. However, since the 1999 Yahoo, ebay and other e-commerce sites were attacked by denial of service, DDoS has become a new security threat on the internet, which is very dangerous and very difficult to protect. Especially with the development of h

IP addresses of suspected controlled devices that have been exploited to launch wifict attacks 2. weak passwords of smart cameras of some brands Weak Password vulnerability is a high-threat but easy-to-use vulnerability of online smart cameras. CNCERT continues to pay attention to the vulnerability fixing situation. At the end of December 2017, CNCERT conducted a sample monitoring and analysis on the vulnerabilities of smart cameras and weak password

divided into computer viruses, worms, malicious mobile code, Trojan horses, backdoor, zombie programs, kernel suites, etc. depending on how it is executed, how it is propagated, and the impact it has on the attack target. A computer virus is the first malicious code type that appears. Computer virus: A self-replicating code that infects itself by embedding itself in other programs, and the infection process usually requires manual intervention to complete. Worm: A class of self-running maliciou

Zombie Network is listed as one of the top ten computer viruses, Microsoft This July has a reward for 250,000 of dollars to capture zombie network operators, it can be seen how abhorrent. Recently, there is news that the Kaspersky Lab teamed up with Microsoft, Kyrus Tech, successfully annihilated the infamous Kelihos botnet, and also hit the back of the zombie network to support the operation of the host service provider, which has provided anonymous

How ADS can cure DDoS attacks According to the 2015 H1 Green Alliance technology DDoS Threat Report, today's large-volume network attacks are gradually showing a growth trend. The recent launch of hammer technology and the failure of Apple's official website in September 12 confirmed this. What is DDoS attack? How can we defend against DDoS attacks?

Enterprises make huge investments to ensure the proper deployment and operation of security systems, so as to protect enterprises from network security threats. In fact, one of the key prerequisites for the normal operation of enterprise security systems is that the traffic is readable. That is to say, if the traffic through the system is encrypted, the security system deployed by the enterprise may not function. VPN (Virtual Private Network) Remote Access has almost become a necessary function

Linux Malware detection tool and Anti-Virus engine ClamAV installation tutorial Malware is any software program designed to interfere with or damage the normal operation of the computing system. Although the most notorious malware include viruses, spyware, and advertising software, their attempts do not cause the same harm: Some steal private information, some delete personal data, and some are between them; another common purpose of malware is to control the system and then use it to launch a

into multiple "batches" as needed and handed over to multiple CPUs for parallel processing. When using a botnet or IaaS, attackers can calculate the results that may take several years in a matter of minutes or hours. A german researcher demonstrated using Amazon's Elastic Computing cloud and a new cluster computing service specifically designed for CPU-intensive graphics computing. From the algorithm perspective, the calculation process of graphics

Cloud Firewall is a new concept, the first by the IT giant Cisco proposed, their approach is: upgrade their firewalls to the "cloud" firewall, to achieve dynamic prevention, active security. Cisco believes that the emergence of the cloud firewall means the emergence of the fifth generation of firewalls (the first four generations are: software firewalls, hardware firewalls, ASIC firewalls, UTM). The 4 characteristics of cloud Firewall include: Anti-Zombie network/trojan, prevent network interna
