BazaCall is a campaign that manipulate users into calling a customer support center, where they are instructed to download an Excel file to unsubscribe from a phony service. When the user opens the Excel file, they are prompted to enable a malicious macro that infects their device with BazaLoader.

This query looks for a Word document attachment, from which a link was clicked, and after which there was a browser download.
This query is not noisy, but most of its results are clean.
It can also hserve as reference for other queries on email attachments, on browser downloads or for queries that join multiple events by time.
Tags: #EmailAttachment, #WordLink, #BrowserDownload, #Phishing, #DedupFileCreate.
Implementation comment #1: Matching events by time.
Matching the 3 different events (saving attachment, clicking on link, downloading file) is done purely by time difference - so could sometimes link together unrelated events.
Doing a more exact lookup would create a much more complex query due to.
Implementation comment #2: Deduping DeviceFileEvents.
Oftentimes there are multiple DeviceFileEvents for a single file - e.g. if the file keeps being appended into before being closed.
So, we query only for the last reported file state to ignore intermediate file states.
Explaining the underlying data:.
BrowserLaunchedToOpenUrl event:.
This query uses the BrowserLaunchedToOpenUrl event, that includes clicks on http:// or https:// links (clicks outside of browsers), or on .lnk files.
For this event, RemoteUrl contains the opened URL.
