- Example analysis of Glupteba malware variants
- Recently, cyberattacks involving the malware glutteba were discovered. It is an older piece of malware that was seen in an operation called "windigo" and was spread to Windows users via a vulnerability. In 2018, a security firm reported that Glupteba had acted independently of Windigo and moved to a pay-per-install adware service. Glupteba activities have different purposes: providing proxy services, exploiting vulnerabilities for mining activities, etc. After studying recently discovered variants of Glupteba, we discovered two undocumented components outside of Glupteba malware: 1.

- What is the hardware architecture in industrial firewall architecture and technology?
- 1) Meeting the stability requirements of the industrial environment. From the perspective of meeting the stability requirements of the industrial environment, industrial firewalls need to consider the impact of their own stability on the industrial network from the hardware and software levels. From this perspective, industrial firewalls need to have both software and hardware bypass functions. Once the device is abnormal or restarts, the Bypass function will be activated, and there is no need to worry about the industrial network being disconnected due to problems with the industrial firewall itself. Bypass, as the name suggests, is a bypass protection system, which means that two networks can be physically connected directly without passing through the industrial firewall system through a specific triggering state (power outage or crash). At this time, the industrial firewall will no longer process the data packets in the network. Based on this design, B

- How to choose a SOAR solution
- SOAR (Security Orchestration, Automation and Response) is regarded as the iconic solution of the next generation SOC and a key mechanism to improve the efficiency of security operations. As we all know, the focus of next-generation SOC is to improve detection and response capabilities. But the current situation today is that the SOC operation team is overwhelmed, the false alarm rate remains high, and the MTTR (mean response time) performance has been difficult to improve. Therefore, the security industry and enterprise security teams have high hopes for SOAR solutions, expecting to significantly improve SOC efficiency in detecting and responding to threats through the deployment of SOAR. However, Party A companies also need to realize that if implemented incorrectly, SOAR solutions will also bring new challenges. Without proper planning, businesses adopting security automation tools may

- How to analyze H3C iMC combined with SNMPv3 protocol to manage equipment from different manufacturers
- Network management software is welcomed by more and more customers, and IT manufacturers are also actively launching their own network management software. As for the use effect and experience, everyone feels it for themselves, and everyone in the IT circle knows it. Based on my recent implementation project, I deployed the iMC operation and maintenance management platform developed by H3C (it is said to be now called "New H3C"), which involves equipment from different manufacturers. I will briefly share it with you. Most network management software manages network devices through the SNMP protocol. So the question is, is SNMP a weird thing? Introduction to SNMP protocol SNMP (Simple Network Management Protocol) is a network management standard protocol in the Internet.

However, the scope of the fault this time is a bit large, and the host machine cannot be opened. Fortunately, the surveillance system left some evidence. The evidence found that the machine's CPU, memory, and file handles continued to rise with the growth of the business... until monitoring could not collect the information. The terrible thing is that there are a lot of Java processes deployed on these hosts. For no other reason than to save costs, the applications were mixed. When a host exhibits overall anomalies, it can be difficult to find the culprit. Because remote login is over, the irritable operation and maintenance can only restart the machine, and then restart the application. After a long time
