Microsoft Security Intelligence, or MSI, says that while Microsoft 365 Defender is equipped to identify and defend against such spurious emails, it is the lack of any tell-tale malicious elements in the emails that is currently proving to be a challenge.  People cancel and renew subscriptions every day and add new ones sometimes by mistake.  Nobody wants to pay for a subscription they don’t want, so when they get a compelling email from a trusted name or a look-a-like, it triggers a reason to contact the fake call center.  But don’t fall for it.  Next, avoid opening files downloaded from questionable websites, via Peer-to-Peer networks, third-party downloaders, and so on.  It is safe to open files or use programs that were downloaded from legitimate pages and via direct links.  

Another important thing is not to open files or website links in irrelevant emails that are received from suspicious or unknown senders.  Quite often, emails of this kind contain malicious files, links designed to deliver malware.  Finally, installed operating systems and software should be kept up to date (Tomas Meskauskas, PCRisk, Do not call the numbers provided in the BazarCall email campaign, June 2nd, 2021,
