The course is coming to an end, please do the following for children's shoes: The students finally wrote a "answer their own questions" article, the previous reading homework to ask questions are answered. Team contributions have not been played well group please review your team members ' contribution points as soon as possible, otherwise will be 0 points processing. Each student fill in the "soft worker level self-evaluation table", to fill in how much time spent, wrote how many co

A number of children who died in an autopsy abroad found

for an exception handling block within the program (the catch block that we usually know), and if an exception handler is found to handle the exception, Windows releases the stack underneath the function where the exception handler block is located, and execute the code inside the exception handling block.3. If Windows does not find any exception processing block to handle this exception, that is, to the program entrance (main) function does not find a suitable exception processing block, Windo

For multiple processes, the parent process generally needs to track the exit status of the child process. Therefore, when the child process ends running, the kernel does not immediately release the table entries for the process table of the session. The information query that satisfies the parent process for subsequent child process exits (postmortem autopsy), of course, if the parent process is still running. After the child process finishes, the par

, the data is actually still on the hard disk, the key is to find the index point, and then the data block that it refers to capture the data, and then save to another partition. The first thing we do when we delete a file with RM is to make sure that we don't write the data to the partition where the file was accidentally deleted. Usually we can have the following choices: 1, with the help of tools. 2, write their own procedures. You need to be able to program and understand the corresponding f

interception system at one level is analyzed. For example, some stack facets and tools for analysis, Jstack, Jmap, kill-3, MAT, Heap Analyser, and so on. Monitor: Monitor system changes and even data flow. such as Jprofiler, JConsole, JStat, Btrace and so on. Autopsy: The system has gone down, but left some "incriminating evidence" to analyze them later. The most famous is the hs_err_pid.log that may be left after the JVM is hung, or the generated cr

Analysis: event records of one intrusion into Linux servers This vulnerability is common in ColdFusion and content management systems. In some cases, a specific attack may succeed, and a high-value server may cause significant data leakage. In other cases, attackers can operate infected hosts on a large scale. Recently, I noticed that multiple IP addresses were attempting to exploit a PHP vulnerability, So I recorded the results using a honeypot. This activity reminds me of the days when the bo

Well, I didn't have a few questions, so it's just a summary, not Writeup. The first day is CTF, which includes encryption and decryption, network protocols, web attack defense, digital forensics, and reverse analysis. So far this competition has not actually participated in several CTF competitions, so experience is still insufficient, such as time control and question-type ideas judgment.In the beginning, I was a web engineer, my teammates were doing

answer also confirms our conclusion. Figure 10 FAQ of chkrootkit Q2 The implementation principles of common Rootkit detection tools are analyzed. Let's look at the limitations of LiveCD detection. The use of LiveCD means to use a pure CD operating system to mount the original storage to perform static analysis/reverse operations on suspicious files, so that you can understand the Rootkit execution logic and the dependent so/ko files, what is the loaded configuration file. If some Rootkit relat

According to foreign media reports, increasingly complex and fine-grained photo editing software allows people to modify photos. some people modify photos only for interest, while others commit fraud. Researchers are currently working on a series of digital forensics tools, including tools for analyzing Image light, to make it easier to identify whether a photo has been processed. According to foreign media reports, MIT's increasingly sophisticated ph

Never shy away from vague business and technical difficultiesThe avoidance mentality of something or technology is caused by the fuzzy anxiety of the thing itself, overcoming the difficulty that the mentality of the vague anxiety causes to the technical or business personnel, which is far more difficult than the difficulty of the thing or the technical ontology, and the key to overcoming this kind of fuzzy anxiety is the continuous reorganization of the information from various aspects and the s

Automated attack forensics 1. volatility--Advanced Memory Forensics Framework ToolAfter the network has been compromised, it is necessary to verify if an attack event has occurred, usually requiring a memory snapshot of the infected host. You can use volatility to perform tasks such as kernel object checking, process memory detection and extraction, and provide forensic analysis capabilities.Volatility1.1 E

"Editor's note" The writer is Casey Dunham. Casey is a professional software developer with more than more than 10 years of experience and is known for its unique approach to application security issues. This article is a domestic ITOM management platform OneAPM engineer compiled and collated.As a security advisor, I evaluate a variety of applications. In all of the applications I've tested, I've found that they typically encounter some processing of exception problems and insufficient logging.

forensics tools that must be speculated on outside the context to generate evidence. In a way, it is a reckless practice to debug by inference. Collect and filter the data to try to infer the problems that occur. If important information is missing, you must test the code again, repeat the steps, and then start the study again. A more efficient approach is to probe applications while the program is running. You can categorize the request parameters,

. Regular copy or tar can take a lot of time (because the file system is repeated recursively), and if you use mirroring, it's not a file, it's a continuous read, and Io is much faster. A simple experience, if a Windows partition, size 100G, put millions of or tens of thousands of files, if copy may not be completed in a day, but if it is a full partition mirror, on the normal server may be less than half an hour. 7, forensics function.

security system requires the combination of security technology and people, while the management of people without technical implementation is often useless. It's not the money that's safe, the rapid advances in technology, the "bottomless pit" of investment, how do you explain a large budget to a leader as a director of information? Not to invest more, security is a responsibility, when the incident comes, you do not "as", also have to bear the responsibility of ineffective management. In ord
