SIMPOBOXSPY is a custom data-exfiltration tool used to upload stolen archives from compromised Windows environments to Dropbox. It authenticates using a supplied access token, accepts explicitly specified files or selects files matching predefined archive extensions, and creates a destination folder named using the current date and time. Its use of legitimate cloud storage helps blend exfiltration traffic with ordinary cloud-service activity.
SIMPOBOXSPY is part of Earth Kurma's toolset in cyberespionage operations targeting government and telecommunications organizations in Southeast Asia, including the Philippines, Vietnam, Thailand, and Malaysia. In these operations, documents are collected by other tooling, packaged into password-protected WinRAR archives, and then uploaded using SIMPOBOXSPY. It serves as the Dropbox exfiltration component, while the separate ODRIZ tool uploads data to OneDrive. SIMPOBOXSPY and associated collection scripts overlap with tooling linked to ToddyCat, but this overlap does not establish that Earth Kurma and ToddyCat are the same actor. No specific initial delivery mechanism is established for SIMPOBOXSPY.

Component leveraging Dropbox for stealthier data exfiltration.
Uploads stolen archives to Dropbox using an access token. It accepts explicitly selected files or automatically selects files with predefined archive extensions. A variant uploads .7z archives. The report explicitly identifies its use by both Earth Kurma and ToddyCat without establishing that the groups are the same actor.
