Entry-level access to Qbot infections is generally obtained via phishing emails with harmful attacks, like Excel (XLS) documents that may use a macro to plant a DLL loader on the victim machine. Taking a look back, we have noticed that Qbot phishing campaigns use different infection file templates. If launched, the Qbot DLL payload is planted and deployed in genuine Windows applications to avoid detection, like Mobsync.exe or MSRA.exe. 

For instance, the DFIR report reveals that Qbot was planted into MSRA.exe and then creates a timelined task for privilege escalation. Besides this, Qbot DLL with the help of malware is added to Microsoft Defender’s execution list, to avoid getting identified when planted into MSRA.exe.
