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
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

The exact definition of a zombie network
A botnet is a logical network of commands controlled by virus-infected and malicious software installed on the host. It is not a topological network in the physical sense, it has a certain distribution, with the continuous spread of the bot program, new zombie computers are added to the network. According to a recent survey, up to 10% of computers on the web are infected by bot programs and become part of a
the most basic level, DDoS attacks are a vain attempt to make a machine or a network resource unavailable to the policy user. Although the methods, motives and policies of DDoS attacks are different, such incursions generally include the service of one or more persons attempting to suspend or suspend the connection between the host and the Internet temporarily or indefinitely.
In general, this is done through the collaboration of a distributed botnet
Nowadays, many operators have a headache for abnormal traffic attack, which is a serious challenge in the telecom field. Telecom operators should construct the prevention system of abnormal flow. The prevention work is an important work within the telecom operators, and it needs the support of the Government and the cooperation of the industry.
Security challenges for IP networks
The first of the security challenges that IP networks are facing is massive traffic attacks. The scale of attack tr
