How to identify true and false Microsoft Security emails

• Generally, if Microsoft publishes a security notice, it will notify the subscriber of the reminder service by email. However, it has been found that many malicious people use spoofed methods to forge Microsoft's Security Bulletin emails. Some emails also trick the recipient into connecting to some websites to download malicious programs, or the emails themselves contain viruses as attachments.

  Fortunately, scammers can always see it. Here are some tips to know if Microsoft's security emails are true.

In addition, we will provide customers with the original complete security bulletin on our website, which contains a link to download the patch.
