A newly discovered malware, dubbed 'WogRAT,' has emerged as a threat targeting both Windows and Linux operating systems. This malicious software utilizes an online notepad platform called "aNotepad" as a clandestine channel for storing and retrieving its harmful code.
WogRAT Malware Has Been Active Since 2022
Researchers discovered a new "WogRAT" malware that thrives inside an online notepad platform. Hackers can use this as a medium to store malicious code that can infect a system.
Researchers at AhnLab Security Intelligence Center (ASEC) identified the "WingOfGod" malware, which has been active since late 2022.
According to cybersecurity experts, the notorious WogRAT malware has been targeting Asian countries, including China, Hong Kong, Singapore, and Japan.

Distribution Methods
While the exact distribution methods remain undisclosed, the malware is likely disseminated through malvertising or similar deceptive techniques. The executables associated with WogRAT bear names resembling popular software titles, aiding in their camouflage during distribution.
Exploiting Online Notepads
A notable aspect of WogRAT's operation is its exploitation of "aNotepad," an online notepad platform. The malware disguises itself as an Adobe tool within a base64-encoded .NET binary hosted on aNotepad.
What's more, this malware is proven to be elusive as it can easily evade suspicion, as legitimate online services like aNotepad are not typically flagged by security tools.
Malware Functionality
Upon execution, WogRAT initially appears benign and may evade detection by antivirus software. However, it contains encrypted source code for a malware downloader, which retrieves a malicious .NET binary from aNotepad. This binary serves as the WogRAT backdoor, enabling communication with a command and control (C2) server.
Supported Functions
Bleeping Computer reports that WogRAT supports five primary functions, which are the following:
- Executing commands
- Downloading files from specified URLs
- Uploading specified files to the C2 server
- Waiting for a specified duration
- Terminating operations
WogRAT Has a Linux Variant
In addition to targeting Windows systems, WogRAT also has a Linux variant distributed in ELF form. This version utilizes Tiny Shell for routing operations and employs additional encryption in its communication with the C2 server.
Unlike the Windows variant, the Linux version does not abuse aNotepad for hosting malicious code.
While WogRAT's distribution methods remain uncertain, its emergence poses a significant threat to Windows and Linux users. This malware underscores the importance of robust cybersecurity measures by exploiting online notepads and employing sophisticated techniques.
