KARAEKARAE

Karae backdoors are typically used as first-stage malware after an initial compromise. The backdoors can collect system information, upload and download files, and may be used to retrieve a second-stage payload. The malware uses public cloud-based storage providers for command and control. In March 2016, KARAE malware was distributed through torrent file-sharing websites for South Korean users. During this campaign, the malware used a YouTube video downloader application as a lure.
