WEB security [4]: File Upload VulnerabilityI have never touched on the vulnerabilities I learned before. The file upload vulnerability allows you to use the WEB to upload certain files. Generally, the file upload vulnerability means that the user uploads an executable script file and obtains the ability to execute commands on the server. File Upload is one of the most common functional requirements on the Internet. The key is whether the process of processing and interpreting files on the server
by the server. If PUT is supported, they should use PUT to upload a specified text file, finally, the script file is changed to the script file through MOVE to achieve the attack purpose.
Cause 4:
Use blank segments in the file header to write horses.
Hazards of the file upload vulnerability:
1. Attackers can directly access normally uploaded files and interpret and execute user-uploaded scripts using the WEB Container of the server, resulting in code execution;
2. Attackers exploit the WEB C
One layer stripped your mind: Decoding the ZeuS online banking trojan in "Deep disguise"
At the very beginning, I receive a block of diaoyumail with A. Doc attachment. We took off the camouflage coat of the ZeuS Trojan step by step using the usual tool Notepad ++, and conducted a very in-depth static analysis. The disguise of this trojan uses a number of key technologies, such as information hiding and encryption and decryption.

I have previously written an article about Client phishing: Using powershell Client for effective phishing, in the process of using each Client for testing, I personally find that the CHM file is the best one to use, but its disadvantage is that it will pop up a black box, which will be noticed by attackers. So ho
Recently, DiscuzX2 was revealed to have two 0day vulnerabilities, one being the SQL injection vulnerability. Attackers can exploit this vulnerability to obtain the user name and password, and the other being the XSS injection vulnerability, attackers can conduct website Trojans, phishing, and other activities. Currently, the official version 0629 has been released for this issue, the following is the vulnerability analysis report of the Nevel security

On the other hand, users have a strong curiosity about some secret things. attackers who use Trojans or virus programs to attack things often exploit the user's curiosity, bind Trojans or virus programs to some gorgeous images, audio and video files, free software files, and other files. Then place these files on some websites, and then entice users to click or download them. You can also send these Trojans or virus-bound files to users through email attachments and instant

I saw a post about computer virus infection and asking for help on the Internet during a security forum.Out of my professional habits, I opened the url mentioned in the article in the virtual machine. I did not find anything suspicious at the beginning, but it looked like a promotion or phishing website, think that this is a common
Although the number of social engineering attacks is unlimited, they all have the following typical features:
Password theft
In terms of this common feature, hackers use information from social network files to guess a victim's password prompt. This technology is used to send emails to Twitter and Sarah Palin.

Including "do not play to deal with game coins 1000 W = 150 RMB + QQXXXXXX" "24-hour manual === ad words automatic filtering === package equipment level + QQXXXXXX" and so on. cheap
, attackers can use similar methods to obtain information about the client. Attackers can achieve this in various ways, including phishing emails and direct queries.
The problem described in VU #800113 this time is that most DNS Cache servers have one or all of these two vulnerabilities.
After talking about the attack principle, I think more people will be concerned about the following: what can we do?
If you are a desktop user, the best way is to wai
Recently, the most powerful Internet vulnerability in history-the DNS Cache vulnerability. This Vulnerability refers to a vulnerable security system on the Internet in our applications. The root cause of poor security lies in design defects. By exploiting this vulnerability, users may not be able to open the webpage. The most important is phishing and financial fraud, which can cause huge losses to victims.

Once authorized, the website can not only know the location of the victim, but also track the victim in real time when the user moves.3.
