MITRE reference S0352
OSX_OCEANLOTUS.D can collect the network interface MAC address on the infected host.56
OSX_OCEANLOTUS.D has a variant that is packed with UPX.7
OSX_OCEANLOTUS.D encrypts its strings in RSA256 and encodes them in a custom base64 scheme and XOR.8
OSX_OCEANLOTUS.D uses file naming conventions with associated executable locations to blend in with the macOS TimeMachine and OpenSSL services. Such as, naming a LaunchAgent plist file com.apple.openssl.plist which executes OSX_OCEANLOTUS.D from the user's ~/Library/OpenSSL/ folder upon user login.9
OSX_OCEANLOTUS.D has disguised it's true file structure as an application bundle by adding special characters to the filename and using the icon for legitimate Word documents.10
Standing S0352
Reach is how much of ATT&CK this tool touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.

Threat group161% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
