- How to analyze Haproxy port reuse
- Author of this article: Spark (Ms08067 intranet security team member) 1. Overview Haproxy is a high-performance load balancing proxy software developed in C language. It provides tcp and http application proxies. It is free, fast and reliable. Similar to frp, it can be run using a configuration file + a server. Advantages: Large-scale business field applications widely support four-layer proxies (transport layer) and seven-layer proxies (application layer). Support ACL (access control list), and can flexibly configure routing windows. It can be run after compiling with cygwin (can be cross-platform) access control list (AccessControlLists, ACL) is a list of commands applied to the router interface. These command lists

- Example analysis of Thin Provision
- Thin provisioning (ThinProvision), sometimes called "oversubscription", is an important emerging storage technology. This article introduces thin provisioning, its working principle, usage limitations, and some usage suggestions. If the storage space used by the application is full, it will crash. Therefore, storage administrators often allocate more storage capacity than the application actually requires to avoid any potential application failure. This approach provides "headroom" for future growth and reduces the risk of application failure. But it requires more physical disk capacity than actual, causing waste. Thin provisioning software eliminates the need to allocate unused disk capacity in advance, resulting in higher overall storage utilization.

- What does shellcode mean?
- 1. Introduction to pre-knowledge points of shellcode programming. What is shellcode? The essence of shellcode is actually a piece of assembly code that can run independently. It does not have any file structure, it does not rely on any compilation environment, and cannot be double-clicked to run like an exe. You can refer to Baidu for a detailed introduction to shellcode, so I won’t go into details here. Why write your own shellcode? Because I have done a lot of penetration in the past six months, the shellcodes used are all generated by CS or MSF, but the shellcode automatically generated by the tool is dead after all, and there is no way to expand the function by yourself. Another example is that you know a new vulnerability, but the vulnerability is Using POC can only pop up a calculation

It is a many-to-many conversion and cannot save public IP addresses. It uses less NAPT: (Network address and port translation ) Similar to Cisco's PAT conversion, NAPT converts the source address of the message and converts the source port. The outbound interface address: (Easy-IP) conversion method is simple, the same as NAPT, that is, converts the source address and source port. It is a multi-purpose method. One-to-one conversion SmartNAT (intelligent conversion): NAPT conversion by reserving a public network address Triplet NAT: a conversion related to the source IP address, source du port and protocol type Two, black hole routing source address conversion

- What are the 8 rules for good APP testing?
- When it comes to software testing, testers definitely think of checking files, functionality, APIs, performance and determining if the software is safe, among other things about a specific part of the software. But for mobile testing, testers have to consider mobile-related features based on user mobile usage patterns. The following mainly talks about mobile testing. For the mobile phone project (application software) of the product, it is mainly system testing. For system testing of mobile application software APP, we usually carry out it from the following perspectives: functional module testing, compatibility testing, installation and uninstallation testing, software update testing, performance testing, user experience testing, cross-event testing, user interface Testing etc. As a software quality assurance manager, I focus on iPhone, Android,

- For some time, ESET researchers have been tracking the activities of Winnti, a group that has been active since 2012 and has targeted the video game and software industry supply chains. Recently, a previously undocumented backdoor was discovered that targets Microsoft SQL (MSSQL). This backdoor bears many similarities to the PortReuse backdoor, another tool used by WinntiGroup and first documented in October 2019. This year, a new backdoor sample, skip-2.0, was detected. The author is a member of the winnti organization. This backdoor targets MSSQL Server 11 and 12 and allows attackers to use magi

- Example analysis of using ZoomEye to find APT attacks
- The data online on ZoomEye is in overwrite and update mode, which means that if the data is not scanned in the second scan, the updated data will not be overwritten. The data on ZoomEye will retain the banner data obtained in the first scan. This mechanism is here In fact, there is a good scene fit in the traceability of this kind of malicious attack: the download servers used by malicious attacks such as Botnet, APT and other attacks are usually directly deactivated and discarded after being discovered. Of course, some are hacked targets, and they are also very violent. Go offline directly! Therefore, many attack sites are likely to be cached online by ZoomEye. Of course, with the data provided in the ZoomEye history api, you can query the number of banners obtained by each scan regardless of whether you cover it or not.

- How to implement APT28 sample analysis
- 1 Background The Fantasy Bear Organization, also known as APT28, is a Russian espionage organization. In 2019, the Fantasy Bear Organization’s activities were extremely frequent. From the think tank intrusion incident at the beginning of this year to the subsequent large and small attacks, APT28 has been involved. Fantasy Bear has a long history. In 2016, the organization became world-famous for hacking into the emails of the Democratic National Committee in an attempt to influence the US presidential election. Spear phishing and 0Day attacks are the usual attack methods of this organization, and the tools they use are updated very quickly. In 2015, no less than 6 different 0Day vulnerabilities were used. This is a considerable project that requires a large number of security personnel to find a large number of unknown vulnerabilities in commonly used software. Book
