Hackers Disguising Winos 4.0 Malware as Gaming Tools: AWarning from Fortinet
Cybersecurity firm Fortinet has issued a warning about ahacking group known as Void Arachne, which is distributing Winos 4.0 malware disguised as gaming tools. The group is targeting unsuspecting users by offering free downloads ofsoftware purportedly designed to enhance gaming experiences, such as game installers and system optimization tools.
The malicious software operates through a cunning multi-step process. Once downloaded and opened, the software triggers a series of events that ultimately lead to the deployment of the Winos 4.0 malware. The process begins with the download of seemingly harmless BMP image files from a server controlled by the hackers.These images are then decoded using the XOR algorithm, revealing a malicious DLL file named you.dll.
This DLL file then proceeds to create an environment conducive to the malware’s installation, downloading three additional files disguised as BMP imagesand saving them as TMP files. These TMP files are then used to extract the malicious libcef.dll file, which establishes a C2 connection with the hacker’s server and deploys the Winos 4.0 malware.
Once installed, the malware grants hackers remote access to the victim’sdevice, allowing them to execute code remotely and even monitor the user’s clipboard and desktop. This level of access grants the hackers the ability to steal sensitive information, control the device, and potentially cause significant damage.
Fortinet urges users to exercise caution when downloading software from unofficial sources. Stick to reputable websites andofficial channels to minimize the risk of encountering malicious software.
This incident highlights the growing sophistication of cyberattacks and the importance of maintaining a strong cybersecurity posture. Users should be aware of the potential dangers lurking within seemingly innocuous software downloads and take proactive measures to protect themselves.
