### Categories
* **Internal reference**: Reference used by the publishing party (e.g. ticket number)
* **Targeting data**: Targeting information to include recipient email, infected machines, department, and or locations.
* **Antivirus detection**: List of anti-virus vendors detecting the malware or information on detection performance (e.g. 13/43 or 67%). Attachment with list of detection or link to VirusTotal could be placed here as well.
* **Payload delivery**: Information about the way the malware payload is initially delivered, for example information about the email or web-site, vulnerability used, originating IP etc. Malware sample itself should be attached here.
* **Artifacts dropped**: Any artifact (files, registry keys etc.) dropped by the malware or other modifications to the system
* **Payload installation**: Location where the payload was placed in the system and the way it was installed. For example, a filename|md5 type attribute can be added here like this: c:\windows\system32\malicious.exe|41d8cd98f00b204e9800998ecf8427e.
* **Persistence mechanism**: Mechanisms used by the malware to start at boot. This could be a registry key, legitimate driver modification, LNK file in startup
* **Network activity**: Information about network traffic generated by the malware
* **Payload type**: Information about the final payload(s). Can contain a function of the payload, e.g. keylogger, RAT, or a name if identified, such as Poison Ivy.
* **Attribution**: Identification of the group, organisation, or country behind the attack
* **External analysis**: Any other result from additional analysis of the malware like tools output Examples: pdf-parser output, automated sandbox analysis, reverse engineering report.
* **Other**: Attributes that are not part of any other category
### Types
* **md5**: You are encouraged to use filename|md5 instead. A checksum in md5 format, only use this if you don't know the correct filename
* **sha1**: You are encouraged to use filename|sha1 instead. A checksum in sha1 format, only use this if you don't know the correct filename
* **sha256**: You are encouraged to use filename|sha256 instead. A checksum in sha256 format, only use this if you don't know the correct filename
* **filename**: Filename
* **filename|md5**: A filename and an md5 hash separated by a | (no spaces)
* **filename|sha1**: A filename and an sha1 hash separated by a | (no spaces)
* **filename|sha256**: A filename and an sha256 hash separated by a | (no spaces)
* **ip-src**: A source IP address of the attacker
* **ip-dst**: A destination IP address of the attacker or C&C server. Also set the IDS flag on when this IP is hardcoded in malware
* **hostname**: A full host/dnsname of an attacker. Also set the IDS flag on when this hostname is hardcoded in malware
* **domain**: A domain name used in the malware. Use this instead of hostname when the upper domain is important or can be used to create links between events.
* **email-src**: The email address (or domainname) used to send the malware.
* **email-dst**: A recipient email address that is not related to your constituency.
* **email-subject**: The subject of the email
* **email-attachment**: File name of the email attachment.
* **url**: url
* **http-method**: HTTP method used by the malware (e.g. POST, GET, ...).
* **user-agent**: The user-agent used by the malware in the HTTP request.
* **regkey**: Registry key or value
* **regkey|value**: Registry value + data separated by |
* **AS**: Autonomous system
* **snort**: An IDS rule in Snort rule-format. This rule will be automatically rewritten in the NIDS exports.
* **pattern-in-file**: Pattern in file that identifies the malware
* **pattern-in-traffic**: Pattern in network traffic that identifies the malware
* **pattern-in-memory**: Pattern in memory dump that identifies the malware
* **yara**: Yara signature
* **vulnerability**: A reference to the vulnerability used in the exploit
* **attachment**: Please upload files using the Upload Attachment button.
* **malware-sample**: Please upload files using the Upload Attachment button.
* **link**: Link to an external information
* **comment**: Comment or description in a human language. This will not be correlated with other attributes (NOT IMPLEMENTED YET)
* **text**: Name, ID or a reference
* **other**: Other attribute
* **named pipe**: Named pipe, use the format \.\pipe\
* **mutex**: Mutex, use the format \BaseNamedObjects\
* **target-user**: Attack Targets Username(s)
* **target-email**: Attack Targets Email(s)
* **target-machine**: Attack Targets Machine Name(s)
* **target-org**: Attack Targets Department or Orginization(s)
* **target-location**: Attack Targets Physical Location(s)
* **target-external**: External Target Orginizations Affected by this Attack
