Talos supports two types of categories, both of which appear in the Reputation Center.
- Threat Categories describe the reason(s) for a lower web reputation threat level. To dispute a threat categorization, submit a web reputation support ticket and select ‘Suggest Threat Category’ from the Suggested Reputation Changes column dropdown, then specify which threat categories you believe should be added or replaced. If you are unsure which new threat category should be applied, you may suggest the Malicious Sites threat category. Please supply additional details in the comment section to aid in investigation.
- Content Categories characterize the general use of the website and are unrelated to any potential threats that the URL or IP may host. To dispute a content category, submit a web categorization support ticket.
Important notes:
- A website can have both a threat category and a content category.
- Some Cisco products may condense both types of categories together into the same field on their management consoles.To dispute a category, you may need to first identify the type of category being displayed and select the appropriate dispute portal that reports the type of category that you would like adjusted.
Web threat categories
Cisco Talos constantly tracks a broad set of attributes to evaluate conclusions about a given host. The below table contains alphabetical listings and descriptions of the standard threat categories used to classify attack types.
| Threat Category | Description |
|---|---|
| Bogon | Bogons are IP Addresses that are known to belong to reserved IP address spaces that is supposedly unallocated or undelegated. Sites in this category are bogons that are known to be sending traffic. |
| Botnets | Known to participate in a Bot network. These include Command and Control (CNC, C2) Servers and sites that deliver or receive data as part of the malicious transaction (bots, zombies). |
| Cryptojacking | Websites with embedded scripts to mine cryptocurrency which use the visitor’s web browser. The script may belong to the owner of the web site, or injected by a malicious third-party, and is used as a method of generating revenue. |
| DNS Tunneling | Sites that provide DNS Tunneling as a service. These services can be for PC or mobile and create a VPN connection specifically over DNS to send traffic that may bypass corporate policies and inspection. |
| Domain Generated Algorithm | Domains that are extracted from malware that employ algorithms that generate domains for potential use in future malicious activities such as hosting malware or as an exfiltration destination. |
| Dynamic DNS | Sites that are hosting dynamic DNS services. Attackers can use this technology as an evasion technique against IP blacklisting. |
| Ebanking Fraud | Known to engage in fraudulent activities that relate to electronic banking. |
| Exploits | Sites that are known to host or aide in exploits, drive-by-downloads and other activities that identifies and compromises vulnerable systems. |

| Linkshare | Websites that share copyrighted files without permission. The web site may be compromised, or otherwise involved in illegal file sharing. |
| Malicious Sites | Sites exhibiting malicious behavior that do not necessarily fit into another, more granular, threat category. |
| Malware Sites | Websites that are known to contain, serve, or support malware in its delivery, propagation, or in carrying out its malicious intent. |
| Newly Seen Domains | Domains that have recently been registered, or not yet seen via telemetry. The behavior of these URLs has not been observed enough to establish the appropriate reputation. Spammers and malicious actors may rely on newly registered, or previously unused domains to disguise their activities, and avoid interdiction due to low reputation. Some legitimate URLs may briefly appear in this threat category as they become visible. |
| Open HTTP Proxy | Hosts that are known to run Open Web Proxies and offer anonymous web browsing services. |
| Open Mail Relay | Commonly used by Spam and Phishing attackers, sites in this category are hosts that are known to offer anonymous email relaying services. |
