For details, see the following:Vulnerability Overview By default, Redis is bound to 0.0.0.0: 6379, which exposes the Redis service to the public network. If aut

Hacking Team attack code analysis Part 1: Flash 0day Recently, Hacking Team, a hacker company dedicated to network listening through attack techniques, was hacked and leaked GB of data containing the company's emails, documents, and attack code. 360 the Vulcan Team immediately obtained the relevant information and analyzed the attack code. We found that at least two remote code execution vulnerabilities for

Hacking Team's principle and Function Analysis of Mac malware Last week, security personnel Patrick Wardle published an article about HackingTeam's new backdoor and virus implants. It also indicates that the Hacking Team becomes active again, bringing new malware. To understand the principles and functions of the malware, some security personnel have made an in-depth analysis. The malware is named Backdoor.

A few days ago, I accidentally visited rootkit and saw an article about wow hacking, which talked about World of Warcraft hacks development and some anti-Warden technologies, reminding me of my Diablo II years. Since I started hack dialbo II a few years ago, I have done a lot of crazy things in retrospect (for example, I used C to completely restore a program from binary ), he has also accumulated a wealth of experience in the hacks production of Diab

If you are attacked by hackers, you will want to find out where the people are attacking themselves, so that we can be targeted for the prevention of hackers work. So how can this be done? This requires us to track hackers, and the hacker's "Dig" out, which has a lot of doorways, to achieve a certain degree of difficulty. This chapter introduces the common user's anti-black requirements from the discovery of hackers to trace the hacker's various methods, the purpose is to let readers after readi

In Unified Communication, we can see many representative services, such as video communication and instant communication ...... Among them, VoIP is one of the "everyone". So why should we integrate VoIP into the field of Unified Communication and how should we integrate VoIP into the planning of enterprises? Today's enterprise communication industry is a popular

Is the network only an infrastructure? Obviously, the current applications have prompted the network to shoulder greater responsibilities. There are still some standard problems to integrate IP speech into traditional networks. What will happen in the future?When is the call no longer a traditional call? VoIP answers this question.All kinds of signals were transmitted through copper wires before January 1, 100. Later, radio broadcast and television si

Application Guide: clarifies the concepts of managed and hosted VoIP Managed, centralized user switch, and hosted VoIP. Oh, my God! There are many available products for enterprises looking for alternative products for the indoor telephone system. This product has various types and sizes. Hosted speech, IP centralized user switches, managed ip pbx, and network-based voice services are all alternative produc

emerging CTI (computer-telephone integration) and VoIP, and traditional PBX uses dedicated technologies, lack of openness and standards, and expensive. In recent years, with the popularity of the Internet and the success of IP, IPPBX Based on the IP protocol has emerged and is expected to solve the shortcomings of traditional PBX. The IPPBX telephone switch system will play an important role in the Communication Industry in the 21st century by integr

At present, many devices are often converted through routers and firewalls. However, the price of the devices that want to meet the OC192 line rate is usually very high, and the investment in comprehensive monitoring of the entire network is very huge. Therefore, using special algorithms and devices to analyze network data while reducing device prices is a feasible solution for the whole network monitoring of VoIP. This paper proposes a new algorithm

In recent research, Forrester recommends the following six steps to help IT organizations avoid VoIP security risks and ultimately ensure their UC systems are secure. In many companies, data networks and telecom worlds converge, and voice and video traffic runs on the same network as other data in the enterprise. Well-known industry terminology such as IP voice (Voice over IP, VoIP), IP telephony (IPT) and

1 Introduction VoIPVoice over IP is a technology that uses an IP network for voice communication. As IP technology is a connectionless technology, the original intention of an IP network is to provide a service called "Best Effort" and "Best Effort, this is suitable for data services that only require accuracy and have no strict requirements on latency. For real-time communication services such as voice and video, their Service Quality is of Service and QoS) it is hard to guarantee. The

How can I obtain domain administrator permissions through VOIP Intranet evaluation? Through the internal VOIP evaluation, we scanned port 5060 and port 5061 to find the IP phone that has been started. Then we found a range and started to connect to the web page with port 80 enabled for each phone. Check the status message of the VOIP Phone. We found that the ph

Label: style blog HTTP Io OS AR for strong sp You must have heard about IP Phone and SIP (software IP Phone ). nowadays standard PSTN phone are being replaced by IP Phones one of the main reason why companies are switching towards IP phones is its low cost and easy setup.

One major drawback of using VOIP and video calls is that Nat and firewall restrict the stable completion of calls. Nat and firewall play an important role in security protection and hardening of internal network availability, but they also pose serious problems for establishing VoIP calls between end users.IETF standard stun, turn, and ice are deployed to handle NAT traversal issues. Stun helps

Currently, traffic revenue is growing rapidly, accounting for about half of the operator's revenue. However, traditional voice communication revenue is still the focus of operators. However, in the 2G or 3G era, there is no obstacle in the 4G era. Complicated VoIP implementation, multiple solutions help LTE transition LTE is a full-IP network, and its network architecture can implement VoIP communication. H

In recent years, broadband services based on IP technology have become increasingly popular. As a result, H.323 multimedia communication systems are no longer limited to private network user groups. Moreover, they are increasingly favored by Internet-based enterprise users. With the gradual popularization of H.323 system applications on the Internet, the conventional problem of firewall and NAT traversal has encountered new challenges, and this contradiction is becoming increasingly apparent.
