Usar la lista de cobertura ampliada
En este documento se explica cómo usar la lista de cobertura ampliada de Web Risk para mejorar la cobertura de las URLs maliciosas con una pequeña cantidad (<10%) de posibles falsos positivos. Se aplica a los siguientes métodos:
Mejorar la detección con la lista de cobertura ampliada de ingeniería social
Puedes consultar las APIs Update y Lookup con la lista de cobertura ampliada de la misma forma que lo haces con las listas de malware, ingeniería social o software no deseado de Web Risk. Cuando hagas una consulta, incluye el tipo SOCIAL_ENGINEERING_EXTENDED_COVERAGE en tu threatTypes. Si usas la lista de cobertura ampliada para ingeniería social, en algunos casos, la cobertura de sitios engañosos y de phishing puede mejorar hasta en un 90 %.
Cuando se encuentre una coincidencia con la lista de cobertura ampliada, ten en cuenta que estas URLs se clasifican con un nivel de confianza ligeramente inferior al de los otros tipos de listas y, por lo tanto, tienen una probabilidad ligeramente mayor de ser falsos positivos.
Ejemplos
En esta sección se incluyen algunos ejemplos de cómo usar la lista de cobertura ampliada.
Usar la lista de cobertura ampliada con uris.search
Método HTTP y URL:
GET https://webrisk.googleapis.com/v1/uris:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&uri=http%3A%2F%2Ftestsafebrowsing.appspot.com%2Fs%2Fsocial_engineering_extended_coverage.html&key=API_KEY
Para enviar tu solicitud, elige una de estas opciones:
curl
Ejecuta el comando siguiente:
curl -X GET \ "https://webrisk.googleapis.com/v1/uris:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&uri=http%3A%2F%2Ftestsafebrowsing.appspot.com%2Fs%2Fsocial_engineering_extended_coverage.html&key=API_KEY"
Usar la lista de cobertura ampliada con threatLists.computeDiff
Método HTTP y URL:
GET https://webrisk.googleapis.com/v1/threatLists:computeDiff?threatType=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&versionToken=Gg4IBBADIgYQgBAiAQEoAQ%3D%3D&constraints.maxDiffEntries=2048&constraints.maxDatabaseEntries=4096&constraints.supportedCompressions=RAW&key=API_KEY
Para enviar tu solicitud, elige una de estas opciones:
curl
Ejecuta el comando siguiente:
curl -X GET \ "https://webrisk.googleapis.com/v1/threatLists:computeDiff?threatType=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&versionToken=Gg4IBBADIgYQgBAiAQEoAQ%3D%3D&constraints.maxDiffEntries=2048&constraints.maxDatabaseEntries=4096&constraints.supportedCompressions=RAW&key=API_KEY"

It applies to the following methods:\n\n- [Lookup API](/web-risk/docs/lookup-api): [`uris.search`](/web-risk/docs/lookup-api#example-urissearch)\n- [Update API](/web-risk/docs/update-api): [`hashes.search`](/web-risk/docs/update-api#example-hashessearch)\n- [Update API](/web-risk/docs/update-api): [`threatLists:computeDiff`](/web-risk/docs/update-api#example-threatlistscomputeDiff)\n\nImprove detection with the Social Engineering Extended Coverage list\n--------------------------------------------------------------------\n\nYou can query the Update and Lookup APIs with the Extended Coverage list as you query with Web Risk's Malware, Social Engineering, or Unwanted Software lists. When you query, include the type SOCIAL_ENGINEERING_EXTENDED_COVERAGE in your `threatTypes`. When you use the Extended Coverage list for Social Engineering, it provides improved coverage of phishing and deceptive sites by up to 90% in some cases.\n\nWhen a match to the Extended Coverage list is found, consider that these URLs are categorized with a slightly lower confidence than the other list types, and therefore have a slightly higher chance of being a false positive.\n| **Note:** These URL matches might not trigger a red warning screen if visited in Chrome, Firefox, Safari or other SafeBrowsing compliant browsers.\n\nExamples\n--------\n\nThis section lists a few examples of how to use the Extended Coverage list.\n\n### Using Extended Coverage list with uris.search\n\n\nHTTP method and URL:\n\n```\nGET https://webrisk.googleapis.com/v1/uris:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&uri=http%3A%2F%2Ftestsafebrowsing.appspot.com%2Fs%2Fsocial_engineering_extended_coverage.html&key=API_KEY\n```\n\nTo send your request, choose one of these options: \n\n#### curl\n\n\nExecute the following command:\n\n```\ncurl -X GET \\\n \"https://webrisk.googleapis.com/v1/uris:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&uri=http%3A%2F%2Ftestsafebrowsing.appspot.com%2Fs%2Fsocial_engineering_extended_coverage.html&key=API_KEY\"\n```\n\n#### PowerShell\n\n\nExecute the following command:\n\n```\n$headers = @{ }\n\nInvoke-WebRequest `\n -Method GET `\n -Headers $headers `\n -Uri \"https://webrisk.googleapis.com/v1/uris:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&uri=http%3A%2F%2Ftestsafebrowsing.appspot.com%2Fs%2Fsocial_engineering_extended_coverage.html&key=API_KEY\" | Select-Object -Expand Content\n```\n\nYou should receive a JSON response similar to the following:\n\n```\n{\n \"threat\": {\n \"threatTypes\": [\n \"SOCIAL_ENGINEERING_EXTENDED_COVERAGE\"\n ],\n \"expireTime\": \"2019-07-17T15:01:23.045123456Z\"\n }\n}\n```\n\n### Using Extended Coverage list with threatLists.computeDiff\n\n\nHTTP method and URL:\n\n```\nGET https://webrisk.googleapis.com/v1/threatLists:computeDiff?threatType=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&versionToken=Gg4IBBADIgYQgBAiAQEoAQ%3D%3D&constraints.maxDiffEntries=2048&constraints.maxDatabaseEntries=4096&constraints.supportedCompressions=RAW&key=API_KEY\n```\n\nTo send your request, choose one of these options: \n\n#### curl\n\n\nExecute the following command:\n\n```\ncurl -X GET \\\n \"https://webrisk.googleapis.com/v1/threatLists:computeDiff?threatType=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&versionToken=Gg4IBBADIgYQgBAiAQEoAQ%3D%3D&constraints.maxDiffEntries=2048&constraints.maxDatabaseEntries=4096&constraints.supportedCompressions=RAW&key=API_KEY\"\n```\n\n#### PowerShell\n\n\nExecute the following command:\n\n```\n$headers = @{ }\n\nInvoke-WebRequest `\n -Method GET `\n -Headers $headers `\n -Uri \"https://webrisk.googleapis.com/v1/threatLists:computeDiff?threatType=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&versionToken=Gg4IBBADIgYQgBAiAQEoAQ%3D%3D&constraints.maxDiffEntries=2048&constraints.maxDatabaseEntries=4096&constraints.supportedCompressions=RAW&key=API_KEY\" | Select-Object -Expand Content\n```\n\nYou should receive a JSON response similar to the following:\n\n```\n{\n \"recommendedNextDiff\": \"2020-01-08T19:41:45.436722194Z\",\n \"responseType\": \"RESET\",\n \"additions\": {\n \"rawHashes\": [\n {\n \"prefixSize\": 4,\n \"rawHashes\": \"AArQMQAMoUgAPn8lAE...\"\n }\n ]\n },\n \"newVersionToken\": \"ChAIARAGGAEiAzAwMSiAEDABEPDyBhoCGAlTcIVL\",\n \"checksum\": {\n \"sha256\": \"wy6jh0+MAg/V/+VdErFhZIpOW+L8ulrVwhlV61XkROI=\"\n }\n}\n```\n\n### Using Extended Coverage list with hashes.search\n\n\nHTTP method and URL:\n\n```\nGET https://webrisk.googleapis.com/v1/hashes:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&hashPrefix=WwuJdQ%3D%3D&key=API_KEY\n```\n\nTo send your request, choose one of these options: \n\n#### curl\n\n\nExecute the following command:\n\n```\ncurl -X GET \\\n \"https://webrisk.googleapis.com/v1/hashes:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&hashPrefix=WwuJdQ%3D%3D&key=API_KEY\"\n```\n\n#### PowerShell\n\n\nExecute the following command:\n\n```\n$headers = @{ }\n\nInvoke-WebRequest `\n -Method GET `\n -Headers $headers `\n -Uri \"https://webrisk.googleapis.com/v1/hashes:search?threatTypes=SOCIAL_ENGINEERING_EXTENDED_COVERAGE&hashPrefix=WwuJdQ%3D%3D&key=API_KEY\" | Select-Object -Expand Content\n```\n\nYou should receive a JSON response similar to the following:\n\n```\n{\n \"threats\": [{\n \"threatTypes\": [\"SOCIAL_ENGINEERING_EXTENDED_COVERAGE\"],\n \"hash\": \"WwuJdQxaCSH453-uytERC456gf45rFExcE23F7-hnfD=\"\n \"expireTime\": \"2019-07-17T15:01:23.045123456Z\"\n },\n }],\n \"negativeExpireTime\": \"2019-07-17T15:01:23.045123456Z\"\n}\n}\n```"]]
