- How to conduct APT organization tracking and governance based on knowledge graph
- Advanced persistent threats (APTs) are increasingly becoming a major threat in cyberspace that cannot be ignored against important assets of governments and enterprises. Since APT attacks often have clear attack intentions, and their attack methods are extremely concealed and latent, traditional network detection methods are usually unable to effectively detect them. In recent years, APT attack detection and defense technologies have gradually attracted the attention of governments and network security researchers from various countries. 1. Research related to the governance of APT organizations in developed countries 1.1 At the strategic level, the United States emphasizes "America First" and "Promoting Peace through Strength." The Trump administration has successively released the "National Security Strategy Report", "Department of Defense Cyber Strategy" and "National Cyber Strategy" ”, explains Trump’s “America First” strategy, emphasizing “cyber deterrence” and

- How to analyze reflected XSS
- 1. Reflected XSS Reflected XSS means that the application obtains untrustworthy data through Web requests and transmits it to Web users without checking whether the data contains malicious code. Reflected XSS is generally constructed by the attacker with malicious code parameters in the URL. When the URL address is opened, the unique malicious code parameters are parsed and executed by HTML. It is characterized by non-persistence and requires the user to click on a link with specific parameters. can cause.

- How to use Bluetooth function to attack and unlock Tapplock smart padlock within two seconds
- A few weeks ago, a YouTuber named JerryRigEverything uploaded a teardown video of the Tapplock Smart Bluetooth Fingerprint Padlock. The video shows that the Tapplock back cover can be removed by simply using a GoPro camera to fix the adhesive base, and then using a screwdriver to easily open the Tapplock lock. It’s a bit incredible. This video aroused my curiosity about the security of Tapplock smart padlock. This smart padlock has fingerprint recognition, mobile phone Bluetooth and Morse code unlocking. While it is convenient, how safe is it? From this, I conducted some research on Tapplock, and finally I achieved the unlocking of Tapplock within 2 seconds.

- How to do an introduction to Wireshark
- Anyone who studies networking must be familiar with Wireshark, but I only knew how to use Wireshark before, and the technical level was very shallow. In the 2015 information security management and assessment national competition test questions, high requirements were placed on the use of Wireshark. In addition, there is a foreign network security tool ranking list (http://sectools.org/), which includes: 125 security tools, among which Wireshark ranks first on the list. All of this prompted the determination to systematically learn Wireshark and use it as the next blog topic after DVWA. Wireshark is currently the most widely used open source packet capture software.

- How to use APT framework TajMahal
- Overview 'TajMahal' is a previously unknown and technically complex APT framework discovered by Kaspersky Lab in the fall of 2018. This complete spy framework consists of two packages named "Tokyo" and "Yokohama". It includes backdoors, loaders, orchestrators, C2 communicators, voice recorders, keyloggers, screen and webcam grabbers, document and encryption key stealers, and even the victim machine's own file indexer. We found up to 80 malicious modules stored in its encrypted virtual file system, which is one of the highest number of plugins we have seen in an APT tool set. To highlight its capabilities, TajMahal is able to etch files from the victim as well as the printer queue.

- How to view Struts2 historical vulnerabilities from a protection perspective
- 1. Introduction The Struts2 vulnerability is a classic series of vulnerabilities. The root cause is that Struts2 introduces OGNL expressions to make the framework flexible and dynamic. With the patching of the overall framework improved, it will now be much more difficult to discover new Struts2 vulnerabilities than before. Judging from the actual situation, most users have already repaired historical high-risk vulnerabilities. Currently, when doing penetration testing, Struts2 vulnerabilities are mainly left to chance, or it will be more effective to attack unpatched systems after being exposed to the intranet. Online analysis articles mainly analyze these Struts2 vulnerabilities from the perspective of attack and exploitation. As the new H3C offense and defense team, part of our job is to maintain the rule base of ips products. Today we will review this system.

- What does select mean in I/O multiplexing?

Function prototype: intselect(intnfds, fd_set*readfds, fd_set*writefds, fd_set*exceptfds, structtimeval*timeout); Several major disadvantages of select: (1) Every time select is called, the fd collection needs to be copied from user mode to kernel mode , this overhead will be very large when there are many fds (2) At the same time, each call to select requires the kernel to traverse all the passed in fds, this overhead will also be very large when there are many fds (3) s

- What are the optimization techniques in website construction?
- Many SEOers know the truth that "content is king and external links are king", but how do they understand "content"? Some SEOers think that content refers to the original articles on the site. This is understandable because it is indeed a basis for website construction. In fact, the content has a wider scope. The following will focus on this "content" to carry out on-site optimization. tricks. First: Why should URL be placed at the front in URL path design? This is because URL path design is very important. Users need to go through the path to access the website, so a reasonable URL design is not only convenient for users to view, but also conducive to search engine inclusion and improves search engine friendliness. If the URL design of the website is unreasonable, it will naturally affect the search index.

- What is JIS-CTF_VulnUpload target drone strategy?
- Vulnhub is one of my favorite playgrounds, and every target drone on it is a cool game. Completely finding all flags is only the basic task, and achieving privilege escalation is the ultimate goal. I am not pursuing the fastest capture of the flag, but rather using a complete attack chain to invade the target drone as much as possible. Therefore, some content in this guide may not be directly helpful for capturing the flag, but you should consider it when dealing with real targets. The target drone "JIS-CTF:VulnUpload" contains 5 flags and is of primary difficulty. It takes an average of 1.5 hours to complete the attack. You can get it from https://www.vulnhub.com/entry/jis-ctf-vulnupload,228/
