SLOTHFULMEDIA is a remote access Trojan written in C++ that has been used by an unidentified "sophisticated cyber actor" since at least January 2017.[1][2] It has been used to target government organizations, defense contractors, universities, and energy companies in Russia, India, Kazakhstan, Kyrgyzstan, Malaysia, Ukraine, and Eastern Europe.[3][4]
In October 2020, Kaspersky Labs assessed SLOTHFULMEDIA is part of an activity cluster it refers to as "IAmTheKing".[5] ESET also noted code similarity between SLOTHFULMEDIA and droppers used by a group it refers to as "PowerPool".[6]

Standing S0533
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.
