McAfee® Advanced Threat Research and Anti-Malware Operations teams have discovered another unknown data reconnaissance implant targeting Korean-speaking users. We have named this threat Operation Oceansalt based on its similarity to the earlier malware Seasalt, which is related to earlier Chinese hacking operations. Oceansalt reuses a portion of code from the Seasalt implant (circa 2010) that is linked to the Chinese hacking group Comment Crew. Oceansalt appears to have been part of an operation targeting South Korea, United States, and Canada in a well-focused attack.
