Satacom downloader, also known as LegionLoader, is a renowned malware family that emerged in 2019. It is known to use the technique of querying DNS servers to obtain the base64-encoded URL in order to receive the next stage of another malware family currently distributed by Satacom.
The Satacom malware is delivered via third-party websites. Some of these sites do not deliver Satacom themselves, but use legitimate advertising plugins that the attackers abuse to inject malicious ads into the webpages. The malicious links or ads on the sites redirect users to malicious sites such as fake file-sharing services.
