This allowed Bitdefender to release a tool that could decrypt some victim's files.\r\n\r\nAfter this breach, the GandCrab developers stated that they would release a second version of GandCrab that included a more secure command & control server in order to prevent a similar compromise in the future.\r\n\r\nYesterday, MalwareHunterTeam discovered that GandCrab version 2 was released, which contains changes that supposedly make it more secure and allow us to differentiate it from the original version. In this article we will provide a quick overview as to what has changed and how you can identify that you are are infected with the GandCrab Ransomware." }, { "type": "observed-data", "spec_version": "2.1", "id": "observed-data--5aa29ecd-59a8-4612-ab33-4ac5950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2018-03-09T14:48:45.000Z", "modified": "2018-03-09T14:48:45.000Z", "first_observed": "2018-03-09T14:48:45Z", "last_observed": "2018-03-09T14:48:45Z", "number_observed": 1, "object_refs": [ "domain-name--5aa29ecd-59a8-4612-ab33-4ac5950d210f" ], "labels": [ "misp:type=\"domain\"", "misp:category=\"Network activity\"" ] }, { "type": "domain-name", "spec_version": "2.1", "id": "domain-name--5aa29ecd-59a8-4612-ab33-4ac5950d210f", "value": "malwarehunterteam.bit" }, { "type": "observed-data", "spec_version": "2.1", "id": "observed-data--5aa29ecd-0734-461e-8497-4ae4950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2018-03-09T14:48:45.000Z", "modified": "2018-03-09T14:48:45.000Z", "first_observed": "2018-03-09T14:48:45Z", "last_observed": "2018-03-09T14:48:45Z", "number_observed": 1, "object_refs": [ "domain-name--5aa29ecd-0734-461e-8497-4ae4950d210f" ], "labels": [ "misp:type=\"domain\"", "misp:category=\"Network activity\"" ] }, { "type": "domain-name", "spec_version": "2.1", "id": "domain-name--5aa29ecd-0734-461e-8497-4ae4950d210f", "value": "politiaromana.bit" }, { "type": "observed-data", "spec_version": "2.1", "id": "observed-data--5aa29ecd-66a0-4072-b4e6-4abc950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2018-03-09T14:48:45.000Z", "modified": "2018-03-09T14:48:45.000Z", "first_observed": "2018-03-09T14:48:45Z", "last_observed": "2018-03-09T14:48:45Z", "number_observed": 1, "object_refs": [ "domain-name--5aa29ecd-66a0-4072-b4e6-4abc950d210f" ], "labels": [ "misp:type=\"domain\"", "misp:category=\"Network activity\"" ] }, { "type": "domain-name", "spec_version": "2.1", "id": "domain-name--5aa29ecd-66a0-4072-b4e6-4abc950d210f", "value": "gdcb.bit" }, { "type": "indicator", "spec_version": "2.1", "id": "indicator--5aa29ee9-e7c8-4012-aeeb-4a21950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2018-03-09T14:49:13.000Z", "modified": "2018-03-09T14:49:13.000Z", "pattern": "[file:name = 'CRAB-Decrypt.txt']", "pattern_type": "stix", "pattern_version": "2.1", "valid_from": "2018-03-09T14:49:13Z", "kill_chain_phases": [ { "kill_chain_name": "misp-category", "phase_name": "Payload delivery" } ], "labels": [ "misp:type=\"filename\"", "misp:category=\"Payload delivery\"", "misp:to_ids=\"True\"" ] }, { "type": "indicator", "spec_version": "2.1", "id": "indicator--5aa29f46-6030-4040-8e28-1527950d210f", "created_by_ref": "identity--55f6ea5e-2c60-40e5-964f-47a8950d210f", "created": "2018-03-09T14:50:46.000Z", "modified": "2018-03-09T14:50:46.000Z", "pattern": "[file:hashes.SHA256 = '966a0852c8adbea0b7b7aada7c2c851ee642c7bca7da3b29ee143f47ddeb90a5']", "pattern_type": "stix", "pattern_version": "2.1", "valid_from": "2018-03-09T14:50:46Z", "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": "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" } } ] }
