In 2011, Hungarian cyber security researchers made a significant discovery of three information-stealing malware: Duqu, Flame, and Gauss. This malware was found to be related as they shared the same framework.

Duqu, designed for information gathering, attempted to conceal data transmissions as regular HTTP traffic by embedding encrypted data within .jpg files.

Flame, a highly intricate malware, aimed to steal information through various methods, including using microphones, webcams, keylogging, and extracting geolocation data from images. It could send and receive commands and data via Bluetooth, storing the acquired information in SQL databases. Flame employed both network connections and USB flash drives for communication. It disguised itself as a Windows Update to infect computers using a counterfeit Microsoft certificate.

Gauss, another malware in the series, focused on information theft. It collected a range of information from compromised systems, including passwords, cookies, and browser history, by intercepting user sessions across different browsers. It also gathered data on computer network connections, processes and folders, BIOS and CMOS RAM details, and local, network, and removable drive information.

Additionally, Gauss could infect USB drives to steal information from other computers.
An important takeaway from the Duqu, Flame, and Gauss information-stealing malware is the sophistication with which complex attacks can originate.
