The Emotet botnet has switched up their malicious spamming campaign and is now heavily distributing password-protected archives to bypass email security gateways. Microsoft noticed this campaign on Friday and it started on Monday with messages pretending to be made on Android. The messages are outdated text in the email subject and body, making it easy for recipients to spot the compromise attempt. Some of the languages used are English, French, and Italian. The theme varies from invitations to meetings and order confirmations to reports, all of them being compressed into a password protected archive.
