The mixer panel lets the user mute the audio, and adjust the volume through virtual faders, and apply effects by pressing the cogwheel next to the mute button. Scenes are groups of sources like live and recorded video, text and audio. The main user interface is organized into five sections: scenes, sources, audio mixer, transitions, and controls. OBS Studio also supports plug-ins to extend its functionality. More experienced users can choose any codecs and containers available in libavcodec and libavformat, or output the stream to a custom FFmpeg URL. It can encode multiple tracks of audio in the AAC format. įor video encoding, OBS Studio can use the x264 transcoder, Intel Quick Sync Video, Nvidia NVENC and the AMD Video Coding Engine to encode video streams into the H.264/MPEG-4 AVC or H.265/HEVC formats. It can stream videos to any RTMP-supporting destination, including YouTube, Twitch, Instagram and Facebook. Written in C/ C++ and built with Qt, OBS Studio provides real-time capture, scene composition, recording, encoding, and broadcasting via Real Time Messaging Protocol (RTMP), HLS, SRT or RIST. OBS Studio is a free and open-source app for screencasting and live streaming. The OBS Project raises funds on the platforms Open Collective and Patreon. It is available for Windows, macOS, Linux distributions, and BSD. One particularly interesting detail was the fact that a large number of BIOPASS' features were implemented to target and steal the private data of popular web browsers and instant messengers typically used in mainland China, which would suggest this was an operation targeted at local Chinese entities, something that might get a state-sponsored actor like APT41 in hot water with their handlers.OBS Studio (also Open Broadcaster Software or OBS, for short) is a free and open-source, cross-platform screencasting and streaming app. However, while the clues were there, Trend Micro has not made any formal link just yet. This would fit into the group's modus operandi since APT41 has been known to engage in cyber-espionage operations during their regular work hours and then carry out financially motivated attacks against online gaming companies across Southeast Asia for personal profits. It is currently unclear who is behind this malware strain however, Trend Micro said it found several clues linking the BIOPASS malware to a group of Chinese state-sponsored hackers known as Winnti or APT41. Per Trend Micro, the attackers use OBS Studio's RTMP (Real-Time Messaging Protocol) streaming capabilities to record the user's screen and broadcast it to an attacker's control panel. Trend Microīut while BIOPASS looks like any other RAT, it also comes with a new feature not seen in any other malware strain-namely, it installs the OBS Studio software on victims' systems. It also has the ability to compromise the private information of its victims by stealing web browser and instant messaging client data. Those who installed the malicious Flash and Silverlight apps would install a legitimate version of the software, but also the BIOPASS RAT, which granted attackers full control over their systems.īIOPASS RAT possesses basic features found in other malware, such as file system assessment, remote desktop access, file exfiltration, and shell command execution. Named BIOPASS, this malware is a remote access trojan (RAT) coded in Python that was spotted in recent attacks targeting online gambling companies in China.ĭiscovered by security firm Trend Micro, the RAT has been disguised inside legitimate installers for Adobe Flash Player or Microsoft Silverlight, two technologies that are still being used in China, despite reaching EOL (end-of-life).Īccording to a report published last week, malicious JavaScript code planted by attackers on the tech/chat support pages of Chinese gambling-related sites redirected users to pages offering would-be victims tainted installers. Security researchers have uncovered a new malware strain that uses the popular OBS Studio live-streaming app to record and broadcast the screen of its victims to attackers.
