[Storm-1811](https://attack.mitre.org/groups/G1046) is a financially-motivated entity linked to [Black Basta](https://attack.mitre.org/software/S1070) ransomware deployment. [Storm-1811](https://attack.mitre.org/groups/G1046) is notable for unique phishing and social engineering mechanisms for initial access, such as overloading victim email inboxes with non-malicious spam to prompt a fake "help desk" interaction leading to the deployment of adversary tools and capabilities.(Citation: Microsoft Storm-1811 2024)(Citation: rapid7-email-bombing)(Citation: RedCanary Storm-1811 2024)(Citation: RedCanary June Insights 2024)
