The GrandSteal infostealer is a brand-new threat that does not seem to be related to any of the infostealers known to malware researchers. This threat has managed to confuse some anti-malware services too, as some of them report that this is a copy of the Quasar RAT. Upon further inspection, however, it turned out that the two threats are not related at all. There has been a report stating that a variant of the GrandSteal infostealer was hosted on a Russian domain. Do not rush to conclusions, though – this does not mean that the threat originates from the Russian Federation.
