The issue identified is “Official Complaint XXX , began an investigation against your company” company -where XXX is an alphanumeric code of between 6-7 characters-although it does not rule out the use of other different issues.
In the email, the user is informed that your company has been unable to adapt and respect the legislation in force with what has been reported. In the body of the message asks the victim to download an attachment to view these complaints.
