Malware family detection

The Malware Family Detection API takes a file hash and returns all malware families to which that sample belongs, based on the detections from the latest AV scan.

General Info about Requests/Responses

• All requests accept the format query field which supports two options: XML or JSON.
• The default response format is JSON (for bulk query, the default is the same as the post format)
• All bulk query rules will accept post payload in XML or JSON
• The number of hashes in a bulk request must not be larger than 100

Malware Family Detection Single Query

Request

GET /api/malware/family/detection/v1/query/{hash_type}/{hash_value}[?format=xml|json]

Path parameters:

• hash_type accepts these options: md5, sha1, sha256
• hash_value must be a valid hash defined by the hash_type parameter

Query parameters:

• format parameter specifies the desired return format: xml or json (default)
• If an entry is not found in single query, HTTP response 404 is returned

Response

{
  "rl": {
    "sample": {
      "sha1": "string",
      "family": {
        "entries": [
          "string"
        ]
      }
    }
  }
}

• sha1
  • The SHA1 hash of the sample.
• family
  • Malware family. Can contain several entries.

Malware Family Detection Bulk Query

This query retrieves the same data as single query does, but for multiple hashes.

Request

POST /api/malware/family/detection/v1/bulk_query/{post_format}[?format=xml|json]

Path parameters:

• post_format parameter defines the post's payload format
• post_format parameter accepts the following options: xml or json

Query parameters:

• format defines the desired return format (xml or json). If not specified, it returns the same format as post_format

  "rl": {
    "query": {
      "hash_type": "string",
      "hashes": [
