The Trojan sends an email to sahro.bella7[at]post.cz with sysscr.ops as the attachment, the string SCreen within the body and a subject with the unique system identifier via SMTPS from one of three previously used accounts. If the actor wishes to download an additional payload to the compromised host, they will respond by sending emails in the following steps. 3) The actor sends an email to trala.cosh2[at]post.cz with the unique system identifier as a subject with a secondary email account and credentials in ASCII hexadecimal format within the message body. This secondary email account is unknown at this time, so we will refer to it as "secondary email account" in future steps. 4) The actor sends an email to the secondary email account with the unique system identifier as a subject with a secondary payload attached with a filename of txt. Cannon opens the email with the correct subject and decodes the hexadecimal data in the body of the message to obtain the secondary email account. 7) The actor sends an email to trala.cosh2[at]post.cz with the unique system identifier as a subject with a file path that the Cannon Trojan will use to save the secondary payload. 8) Cannon logs into the secondary email account via POP3S looking for emails with a subject that matches the unique system identifier. Cannon opens the email with the correct subject and decodes the hexadecimal data in the body of the message to obtain the file path that it will use to move the downloaded auddevc.txt file. 12) Cannon moves the downloaded file to the specified path
