Background
PCrisk describes Matanbuchus as a loader sold by its authors under a Malware-as-a-Service (MaaS) model, engineered to trigger chained infections.
Because it operates as a MaaS, the payloads it delivers and the motives behind each campaign shift according to whichever criminals are renting it. Matanbuchus has been seen in attacks on US universities and high schools, as well as against a Belgian high-tech organization.
