In early September 2021, the group has been obeserved exploiting a 0day in Microsoft MSHTML (CVE-2021-40444). Investigation lead researchers to believe that they are an Initial Access Broker (IAB) who appear to be working with the Russian cyber crime gang known as FIN12 (Mandiant, FireEye) / WIZARD SPIDER (CrowdStrike). This threat actor deploys tactics, techniques and procedures (TTPs) that are traditionally associated with more targeted attacks, like spoofing companies and employees as a means of gaining trust of a targeted organization through email campaigns that are believed to be sent by real human operators using little-to-no automation. Additionally and rather uniquely, they leverage legitimate file-sharing services like WeTransfer, TransferNow and OneDrive to deliver the payload, namely BUMBLEEBEE and BAZARLOADER, further evading detection mechanisms. This level of human-interaction is rather unusual for cyber crime groups focused on mass scale operations.",
