In-depth analysis of new poser Trojan LogPOS In recent years, POS malware activities have been frequent. This article analyzes a new member LogPOS sample found in 2015. An important feature of the malware is that it uses the mail slot to avoid traditional detection mechanisms. In addition, in this sample, the main program creates a mail slot and acts as a mail slot server, while the code injected into each

following operations (some commands overlap with the previous ones ):Update/Library/Hash /. hashtag /. update or read the hash file/Library/Parallels /. the cfg file automatically downloads the file from a URL to decompress or open the compressed application, and runs an executable file, or execute code from a dynamic library to kill a process and delete a file or disconnect C2 connection through the path 0x03. Conclusion: This OS x OceanLotus Trojan is obviously a mature Trojan dedicated to

Today's malware will use some clever technologies to circumvent the traditional signature-based anti-malware detection. Intrusion prevention systems, web page filtering, and Anti-Virus products are no longer able to defend against new categories of attackers. Such new categories combine complex malware with persistent remote access features, the objective is to s

provides a thorough description of the latest vulnerabilities, repair methods, and legal public channels. It provides detailed information on malware analysis, penetration testing, SCADA, VoIP, Web security, and other topics, analyzes how hackers locate the system, damage the protection scheme, write malicious code, and exploit the defects of Windows and Linux systems. With this book, you will be able to use the latest technology to find and fix secu

As Android's global market share continues to grow, the number of malware against Android platforms has also increased sharply. McAfee's third-quarter report pointed out that only in the third quarter, the number of malware on the Android platform has increased by 37%. Maybe the numbers are not the most intuitive, and the user's personal experience is the best way to describe everything. Perhaps many Androi

The cooling in Guangzhou over the past few days has finally made berwolf really feel the subtropical winter. It turns out so cute. Although the temperature is low, Microsoft's wind in the IT industry is still very hot, especially since the appearance of Windows XP SP2, this is the safest Service Pack in history that Microsoft has been advocating, but it is a slap in the face of Microsoft. The vulnerability is like a ball in the eye, people's fantasies about security have been shattered. However,

First, the Reverse debugging technology Anti-debugging technology is a common kind of counter detection technique, because malware always attempts to monitor its own code to detect if it is being debugged. To do this, the malware can check whether its own code is set to break the point, or directly through the system to detect the debugger. 1. Breakpoint In order to detect if its code is set to a breakpoint

As a network manager, malware analysis may not be our most important task. However, if a malware affects your desktop application, you may consider the nature of this unfamiliar malicious code. In general, starting from behavior analysis, you can start your investigation, that is, to observe how malware affects the file system, registry, and network, and quickly

Apt attacks against Israel and Palestine This short report introduces a series of attacks against Israel and Palestine. It uses malicious files as the source of communication for a large number of influential or politically relevant organizations. Through our investigation, no apt record with the same behavior previously. However, we can still find some similar attacks.That was the summer of 2014. We obtained malicious samples in some small infrastructure, which showed that attackers were poor o

Nowadays, many people use the Internet as a natural extension of their daily life. Whether it's chatting with friends, focusing on current affairs, doing special research or watching movies, they all need to use the Internet. We know that the bad guys must also know. It risk managers often teach end users about standard Web security recommendations: Don't click, uninstall plug-ins, change passwords regularly, use anti-virus software, etc., but that doesn't seem to work. So it's not surprising t

Dnscrypt is a tool released by OpenDNS that ensures security between the client and the DNS server. Dnscrypt, which runs as a DNS proxy, focuses on communication security between the client and the first-level DNS server, and can cache DNS resolution. In short, the Dnscrypt is able to encrypt the DNS query communication process before the native to the DNS server, thereby preventing DNS hijacking by the network service provider. DNS requests and retu
