I've been working on PHP applications for the last four years. PHP is really easy to write. But PHP also has some very serious flaws. Below I will give my reasons why PHP is not suitable for larger sites than small amateur websites. 1. Bad support

and remove bots as it administrators. 1. docized If you want to effectively manage IT risks, you need a complete Event Response Process. The absence of action plans can be said to be the biggest obstacle to effective and secure response. Immediately begin to develop active preventive measures to minimize the potential impact of malware attacks. If you want your organization to be able to handle botnet hija

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

Blockchain Enthusiast (qq:53016353) First of all, let me say first, we will fully support the cottage currency algorithm, and we believe that many coins will be used in the future of this algorithm. In particular, considering the scrypt ASIC mining machine has been continuously emerging, and may have a 250M miner appeared. The algorithm of the cottage currency is defective, but the defect will outweigh the advantages. Let's look at the pros and cons of the cottage-currency algorithm. Advantages

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

Similar to the previous jQuery focus chart animation, it al

Nowadays, in the Internet era where "information is at your fingertips", many people have their own email, QQ number, MSN, and other communication tools to contact friends and family, many people register their own accounts on their social networking websites, which will undoubtedly greatly facilitate our work and life. However, as attackers target social networks, ordinary users face a huge risk of being hacked when surfing the Internet. The focus of a social network is to build online communit

because the protocol is relatively complex, so the effect is very obvious, and protection is very high, such as the CC attack on the game server, is to use the online game itself some application protocol vulnerabilities. The damage of large-ddos attacks has also changed, and the previous DDoS attacks have been mainly targeted at portal sites, and now the object of attack has changed. such as DNS server, VoIP authentication server or online games server, the Internet or business network key ap

figure 17. Chart 16 (bot list displayed on the C C Management Panel) Figure 17 other task interfaces in C C The two C C servers jointly control about 1,400 bots. The first botnet contains about 1,100 bots, and the second contains about 300 bots. During analysis, botnet bots were used to brute force crack WordPress passwords. Table 18 shows a brute-force cracking task, and Table 19 shows the results o

brute force cracking. All of the attackers are unable to launch a wide range of distributed brute force attacks because of network bandwidth problems, due more to the network bandwidth constraints of the target server than to the botnet's own network bandwidth. Because the network bandwidth of the botnet is not enough, even if it is very slow, the attacker can use the quantity instead of quality, using many of the bad network of zombie computers to l

As a software, rootkit can connect to and enter the computer, while hiding signs of its existence from users and administrators. Although rootkit itself may be harmless, almost all hidden software or processes are faulty. Different from viruses, rootkit can gain computer management permissions. Rootkit is the most serious damage and threat to viruses. The biggest problem with processing rootkit is that once the system is intruded, it is difficult to p

too complex. "Most people think that limiting who can access and what they can access is not a simple task ." "Our current situation is that we cannot only let people do what they want," he said. Too many people advocate that if we want to seize and retain good employees, we must allow them to install programs and surf the Internet freely, but there is no other way, so we have to lock the system ."

In general, is used to do information and other resources to share, mobile (APP): Mobile devices are mostly used in the device applications, to achieve mobile phone-side control IoT environment to interact These wireless protocols (and more) are commonly used by the control sensors a

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

Some time ago, the NTP amplification attack was very active. Let's analyze it briefly. Attack principles: 1,ExploitationUDPThe natural weakness of the Protocol, that is, you can directlyClientSend data; 2,InternetThere are a large number of open and distributedNtpserverTo respond to the synchronization request. 3, Ratio DNS The biggest difference between reflection amplification and attack power is NTP Unique Monlist Function, (Monlist Co

In addition, the active defense technology of the Norton 2009 real-time SONAR (Symantec Online Network for Advanced Response) can effectively trigger alarms and kill unknown viruses in real time. In addition, the Norton 2009 feature "botnet protection" and a severe infection system recovery tool automatically prevents hackers from controlling computers, s
