![]() ![]() Once the malware payloads are executed on the system, they establish communication with a Command and Control (C2) server controlled by the attacker. ![]() ![]() It also provides detailed information on the techniques used by the malware to evade detection by security software and execute its payload. This blog provides a detailed technical analysis of malicious “wextract.exe” that is used as a delivery mechanism for multiple types of malware s, including Amadey and Redline Stealer. McAfee Labs collected malicious wextract.exe samples from the wild, and its behavior was analyzed. For example, they may create a fake Windows Installer package that appears to be a legitimate software update or utility but also includes a modified “wextract.exe” that encrypts the victim’s files and demand s a ransom payment for their decryption. Ransomware Delivery : Malicious actors can use a fake or modified “wextract.exe” to install ransomware on a victim’s system.They can use the modified wextract.exe to create a backdoor or establish a remote connection to the victim’s computer, allowing them to carry out various malicious activities. Remote Access : Malicious actors can use a fake wextract.exe to gain remote access to a victim’s computer.Malicious actors can modify the code to include keyloggers or other data-stealing techniques. Information stealing : A fake or modified wextract.exe can be used to steal sensitive information from a victim’s computer.They can disguise the malware as a legitimate file and use the fake wextract.exe to extract and execute the malicious code. Malware Distribution : Malicious actors can use a fake version of the wextract.exe to deliver malware onto a victim’s computer.Some common ways that malicious actors use a fake or modified version of wextract.exe include: However, like other executable files, it can be vulnerable to exploitation by malicious actors who might use it as a disguise for malware. It is a legitimate file that is part of the Windows operating system, and it is located in the System32 folder of the Windows directory. Cabinet files are compressed archives that are used to package and distribute software, drivers, and other files. Wextract.exe is a Windows executable file that is used to extract files from a cabinet (.cab) file. McAfee Labs have identified an increase in Wextract.exe samples, that drop a malware payload at multiple stages. ![]()
