Holmes Security Coach – Content

Content checks

This page will give explanation about the executed checks by the Holmes Security Coach regarding the content elements of an e-mail. Every check is further explained by the meaning of the result and how to be interpreted.

  • Probably safe

    There are no guaranties but based on our checks the e-mail seems to be reliable. Are you doubting the authenticity of this e-mail? Please report the message using the Life Line. You will receive feedback automatically.

  • Watch out!

    We have detected signals that you might be dealing with phishing, but we cannot be sure. Are you doubting the authenticity of this message, use the Life Line in the Holmes Security Coach to report the e-mail.

  • Potential threat!

    It is very likely that you are dealing with phishing. Report the received e-mail with the Life Line. When your system administrator recognizes the e-mail as phishing too, the e-mail will be blocked for your colleagues.

Attachment

Attachments are files or folders added to the e-mail. Attachments to an e-mail are a simple and easy way of sharing files or folders with, for example a colleague but cyber criminals also abuse it to send malicious files.

 

Attachment is Red, what does this mean?
The e-mail contains a potentially malicious attachment and is therefore risky to open. We recommend you to use the Life Line.

 

Attachment is Orange, what does this mean?
The e-mail contains a potentially risky attachment. Check the sender: is the sender known and makes the cause of the e-mail any sense. Are there more checks red or orange? We recommend you to use the Life Line.

 

Attachment is Green, what does this mean?
The attachment contains relative safe files or the e-mail does not have any attachments. This check is passed but be aware of the other checks.

Domain reputation

The domain is the part of an e-mail address what belongs to an organization or a person, the organization or person owns the domain. As an example: the domain google.nl is owned by the company Google. The domain and who owns it says something about the reliability and this is translated to a domain reputation score. The higher the reputation, the more reliable the domain is.

 

Domain reputation is Red, what does this mean?
The domain has no or a low reputation and is therefore less reliable. We recommend you to use the Life Line.

 

Domain reputation is Orange, what does this mean?
The domain has a low reputation and is therefore less reliable. Are there more checks red or orange? We recommend you to use the Life Line.

 

Domain reputation is Green, what does this mean?
The domain has a high reputation and is therefore more reliable. This check is passed but be aware of the other checks.

Holmes Community

The Holmes Community Blacklist is a list of potential malicious e-mail addresses detected and selected by Holmes users and administrators. As soon as the community determines an e-mail address is potentially malicious, this e-mail address will be added to the blacklist. This way, you as a Holmes user, you have the complete community at your disposal.

 

Holmes Community is Red, what does this mean?
The e-mail address is on the Holmes Community Blacklist and is therefore potentially malicious. We recommend you to use the Life Line.

 

Holmes Community is Orange, what does this mean?
The e-mail address is not (yet) on the Holmes Community Blacklist. Be aware because it can be an unknown e-mail address, but it does not mean it is safe. Are there more checks red or orange? We recommend you to use the Life Line.
