A SlideShare entry identifies an AhnLab presentation, "From stealing confidential data to revenue-generating attacks," as covering Andariel Group activity from 2014 to 2018. The usable excerpt supports only a high-level finding: the material frames Andariel's operations as evolving from espionage-oriented data theft toward financially motivated attacks. The excerpt does not provide specific victims, malware families, infection steps, infrastructure, or IOCs, so the archive should treat it as a sparse source rather than infer operational details from the surrounding recommended-slide listings.
