Nevertheless the tool\n  inspects all string literals in the executable to find all HTTP URLs, which\n  might include the feed URL. This strategy has limits and can't catch URLs,\n  which weren't fully hardcoded as strings or obfuscated in another way. The\n  found URLs are printed for further investigation through the user to allow a\n  better risk estimation. If an insecure URL serving an AppCast can be found,\n  it is likely that the app is vulnerable, otherwise it can't be excluded.\n\n* *BROKEN UPDATER*: the app doesn't have exclusions from ATS while the feed\n  URL is insecure and it was compiled against OS X 10.11 SDK, which causes that\n  ATS is enabled and insecure HTTP requests are blocked by default. That means\n  the updater won't be able to download any updates.\n\n\n## Usage\n\n```\ncurl -sSLO https://raw.githubusercontent.com/mrackwitz/Jeroboam/master/jeroboam\nless jeroboam\nruby jeroboam\n```\n\nWhile you could theoretically just pipe the raw contents of the executable into\nyour Ruby interpreter as seen below, this is not a fail-proof concept.\nSo the recommended way would be as seen above: download the script and run it\nnot before you made sure yourself that everything is alright.\n\n```shell\n\u003e curl -sSL https://raw.githubusercontent.com/mrackwitz/jeroboam/master/jeroboam | ruby\n```\n\n## Exemplary Output\n\n![Exemplary Output](https://raw.github.com/mrackwitz/jeroboam/assets/output.png)\n\n## License\n\n\u003eCopyright (c) 2016 Marius Rackwitz\n\u003e\n\u003ePermission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the \"Software\"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:\n\u003e\n\u003eThe above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.\n\u003e\n\u003eTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
