For example, we check the hostnames or IP addresses that were serving up malicious code.\r\n\r\nBefore getting further, let\u00e2\u20ac\u2122s define a few concepts to better understand the topic we are discussing today. A host name can be:\r\n\r\nA domain name (i.e. http://example.com/)\r\nA fully qualified domain name (i.e. http://test.example.com/)\r\nAn IP address (i.e. http://127.0.0.1/)\r\nIt\u00e2\u20ac\u2122s not as usual, but IP addresses can indeed be directly used as the URL and when that happens it is called an IP-Literal Hostname (see Eric Lawrence\u00e2\u20ac\u2122s post on this subject).\r\n\r\nIP addresses (IPv4) follow the dot-decimal notation which is four numbers, each ranging from 0 to 255, separated by dots. But then, to make things a little more complicated, we have exceptions, such as the non-dotted IP literals, in decimal (http://2130706433/) or octal form (http://017700000001/).\r\n\r\nThis takes us to a recent infection chain for the RIG exploit kit where we came across such an occurrence." }, { "type": "observed-data", "spec_version": "2.1", "id": "observed-data--58dcc001-5268-4445-a538-457e950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2017-03-30T12:27:57.000Z", "modified": "2017-03-30T12:27:57.000Z", "first_observed": "2017-03-30T12:27:57Z", "last_observed": "2017-03-30T12:27:57Z", "number_observed": 1, "object_refs": [ "url--58dcc001-5268-4445-a538-457e950d210f" ], "labels": [ "misp:type=\"link\"", "misp:category=\"External analysis\"", "osint:source-type=\"blog-post\"", "admiralty-scale:source-reliability=\"b\"" ], "object_marking_refs": [ "marking-definition--613f2e26-407d-48c7-9eca-b8e91df99dc9" ] }, { "type": "url", "spec_version": "2.1", "id": "url--58dcc001-5268-4445-a538-457e950d210f", "value": "https://blog.malwarebytes.com/cybercrime/2017/03/websites-compromised-decimal-ip-campaign/" }, { "type": "indicator", "spec_version": "2.1", "id": "indicator--58dcc07e-6c44-439a-8887-4de8950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2017-03-30T12:27:13.000Z", "modified": "2017-03-30T12:27:13.000Z", "description": "Payload (Smoke Loader)", "pattern": "[file:hashes.SHA256 = '4bed780a55e6179e4a1236444c34398af50d3bea39f86eb877089265f833bda5']", "pattern_type": "stix", "pattern_version": "2.1", "valid_from": "2017-03-30T12:27:13Z", "kill_chain_phases": [ { "kill_chain_name": "misp-category", "phase_name": "Payload delivery" } ], "labels": [ "misp:type=\"sha256\"", "misp:category=\"Payload delivery\"", "misp:to_ids=\"True\"" ] }, { "type": "indicator", "spec_version": "2.1", "id": "indicator--58dcc093-2e94-4149-aa7f-468d950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2017-03-30T12:27:13.000Z", "modified": "2017-03-30T12:27:13.000Z", "description": "Malicious redirect", "pattern": "[network-traffic:dst_ref.type = 'ipv4-addr' AND network-traffic:dst_ref.value = '104.238.158.235']", "pattern_type": "stix", "pattern_version": "2.1", "valid_from": "2017-03-30T12:27:13Z", "kill_chain_phases": [ { "kill_chain_name": "misp-category", "phase_name": "Network activity" } ], "labels": [ "misp:type=\"ip-dst\"", "misp:category=\"Network activity\"", "misp:to_ids=\"True\"" ] }, { "type": "indicator", "spec_version": "2.1", "id": "indicator--58dcf9a5-e148-42e4-a093-4b8202de0b81", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2017-03-30T12:27:17.000Z", "modified": "2017-03-30T12:27:17.000Z", "description": "Payload (Smoke Loader) - Xchecked via VT: 4bed780a55e6179e4a1236444c34398af50d3bea39f86eb877089265f833bda5", "pattern": "[file:hashes.SHA1 = '190cef3dc30d0317955b60e88bb31b924f440882']", "pattern_type": "stix", "pattern_version": "2.1", "valid_from": "2017-03-30T12:27:17Z", "kill_chain_phases": [ { "kill_chain_name": "misp-category", "phase_name": "Payload delivery" } ], "labels": [ "misp:type=\"sha1\"", "misp:category=\"Payload delivery\"", "misp:to_ids=\"True\"" ] }, { "type": "indicator", "spec_version": "2.1", "id": "indicator--58dcf9a6-cbf4-44f0-b647-463802de0b81", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2017-03-30T12:27:18.000Z", "modified": "2017-03-30T12:27:18.000Z", "description": "Payload (Smoke Loader) - Xchecked via VT: 4bed780a55e6179e4a1236444c34398af50d3bea39f86eb877089265f833bda5", "pattern": "[file:hashes.MD5 = '6da59c5e5a3c4e05f0fdfaa618656a83']", "pattern_type": "stix", "pattern_version": "2.1", "valid_from": "2017-03-30T12:27:18Z", "kill_chain_phases": [ { "kill_chain_name": "misp-category", "phase_name": "Payload delivery" } ], "labels": [ "misp:type=\"md5\"", "misp:category=\"Payload delivery\"", "misp:to_ids=\"True\"" ] }, { "type": "observed-data", "spec_version": "2.1", "id": "observed-data--58dcf9a7-5388-4918-abe0-414502de0b81", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2017-03-30T12:27:19.000Z", "modified": "2017-03-30T12:27:19.000Z", "first_observed": "2017-03-30T12:27:19Z", "last_observed": "2017-03-30T12:27:19Z", "number_observed": 1, "object_refs": [ "url--58dcf9a7-5388-4918-abe0-414502de0b81" ], "labels": [ "misp:type=\"link\"", "misp:category=\"External analysis\"" ] }, { "type": "url", "spec_version": "2.1", "id": "url--58dcf9a7-5388-4918-abe0-414502de0b81", "value": "https://www.virustotal.com/file/4bed780a55e6179e4a1236444c34398af50d3bea39f86eb877089265f833bda5/analysis/1490743909/" }, { "type": "marking-definition", "spec_version": "2.1", "id": "marking-definition--613f2e26-407d-48c7-9eca-b8e91df99dc9", "created": "2017-01-20T00:00:00.000Z", "definition_type": "tlp", "name": "TLP:WHITE", "definition": { "tlp": "white" } } ] }
