Introduction
Riot sends phishing simulation emails. If your Barracuda configuration does not include the necessary domains or settings, some of these emails may be blocked, which can distort your campaign statistics.
Definition
Barracuda Email Protection / Gateway is an email filtering solution (anti-spam, anti-phishing, content filtering) and URL analysis tool. It allows you to define approved senders, URL allowlists, and message acceptance policies.
✅ Associated Options / Functionalities
🔒 Allowing Approved Senders and Domains
Log in to Barracuda via Barracuda Cloud Control → Email Protection Barracuda Campus
Check the settings of the Approved Sender List (approved senders list)
Add
noreply.linkand/or the specific domains used by Riot✅ This ensures that messages sent by Riot are not blocked by sender filtering.
🌐 URL / Domain Allowlist
Access the URL filtering or web protection settings in Barracuda
Add the attack domains provided by Riot (replace placeholders)
For example:
domain1.com,domain2.com,domain3.com
Ensure that these domains are correctly included in the Whitelist of authorized URLs
⚙️ Additional Configuration
Ensure Barracuda does not block messages from legitimate Riot IPs by excluding or adding them to trusted lists
Review content or reputation filtering rules to make sure Riot messages are not rejected
If upstream services (proxy, third-party filters) are placed before Barracuda, make sure they do not block headers or URL conversions that could impact detection
💡 ➕ Little Extra:
Use the actual attack domains generated from your Riot account rather than placeholders
Regularly verify that the approved lists contain all necessary entries
Ensure that the applied policies allow incoming messages with at least moderate detection level, depending on context
