File handlers are configuration\r\nproperties of many operating systems. Applications can modify the file handler for a given file extension to call an arbitrary\r\nprogram when a file with the given extension is opened.\r\n Relationships\r\nThis table shows the other attack patterns and high level categories that are related to this attack pattern. These\r\nrelationships are defined as ChildOf and ParentOf, and give insight to similar items that may exist at higher and lower levels\r\nof abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack\r\npatterns that the user may want to explore.\r\nNature Type\r\nChildOf Standard Attack Pattern - A standard level attack pattern in CAPEC is focused on a specific methodology or technique used in an attack. It\r\nThis table shows the views that this attack pattern belongs to and top level categories within that view.\r\n Mitigations\r\nInspect registry for changes. Limit privileges of user accounts so changes to default file handlers can only be performed by\r\nauthorized administrators.\r\n Taxonomy Mappings\r\nCAPEC mappings to ATT\u0026CK techniques leverage an inheritance model to streamline and minimize direct\r\nCAPEC/ATT\u0026CK mappings. Inheritance of a mapping is indicated by text stating that the parent CAPEC has relevant\r\nATT\u0026CK mappings. Note that the ATT\u0026CK Enterprise Framework does not use an inheritance model as part of the\r\nmapping to CAPEC.\r\nRelevant to the ATT\u0026CK taxonomy mapping (also see parent)\r\nEntry ID Entry Name\r\n1546.001 Event Triggered Execution:Change Default File Association\r\n Content History\r\nSubmissions\r\nSubmission Date Submitter Organization\r\n2015-11-09\r\n(Version 2.7)\r\nCAPEC Content Team The MITRE Corporation\r\nModifications\r\nModification Date Modifier Organization\r\n2018-07-31\r\n(Version 2.12)\r\nCAPEC Content Team The MITRE Corporation\r\nUpdated References\r\n2019-04-04\r\n(Version 3.1)\r\nCAPEC Content Team The MITRE Corporation\r\nUpdated Related_Weaknesses\r\n2020-07-30\r\n(Version 3.3)\r\nCAPEC Content Team The MITRE Corporation\r\nUpdated Taxonomy_Mappings\r\nhttps://capec.mitre.org/data/definitions/556.html\r\nPage 1 of 2\n\nMore information is available — Please select a different filter.\r\nSource: https://capec.mitre.org/data/definitions/556.html\r\nhttps://capec.mitre.org/data/definitions/556.html\r\nPage 2 of 2",
