KillPhish Widget

The KillPhish widget is pictured below:

• Risk Level This is the risk level the email was classified as by the plugin. There are three risk levels: low risk (for scores >= 95), medium risk (for emails scored between 60 and 95), and high risk (for emails scored below 60). Several different factors influence an email's score: the headers (DKIM, DMARC, and SPF), if certain attachments are included in the email (HTML and EXE attachments, for example, decrease an email's score), and if certain words/phrases appear in the email. Also, any links in the email will be checked by Google Webrisk and if they are dangerous, the email will be marked as high risk.
• Helpful Tips contains suggestions for dealing with potential harmful emails, including reviewing links before clicking, verifying file types of attachments, and considering the ramifications of following any instructions or actions requested in the email.
• Details lists important properties of the email and their values, including the sender, subject, SPF record pass/fail (if SPF checks fail, the email will be labeled as high risk), attachments, and links contained in the email. Only shown if Advanced Threat Protection is on for the KillPhish plugin.
• Links/Attachments lists all links and attachments in the email, and their associated URLs and file types. Only shown if Advanced Threat Protection is on for the KillPhish plugin.
• Words/Phrases assesses certain keywords and phrases typically associated with risky emails, including but not limited to, 'password', 'irs', 'label', and 'invoice'. Only shown if Advanced Threat Protection is on for the KillPhish plugin.

* Disclaimer: Users should remain vigilant against email security threats, even if the Advanced Threat Protection feature is turned on in your plugin. ATP is not capable of detecting every social engineering/phishing threat in emails. You should use the other tools that Hook Security, Inc provides to educate your users about the various threats posed by phishing and social engineering, and how to detect these attacks.
