While the server component is written in Golang, the GUI Client is written in C++ QT for cross-platform compatibility.\\n\\nIt comes with a wide range of features, including fully encrypted communications, command execution, credential and screenshot managers, and a remote terminal, among others. An early iteration was publicly released by a GitHub user named \\&#8221;RalfHacker\\&#8221; (@HackerRalf on X) in August 2024, who describes themselves as a penetration tester, red team operator, and \\&#8221;MalDev\\&#8221; (short for malware developer).\\n\\n![DFIR Retainer Services](data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mP8Xw8AAoMBgDTD2qgAAAAASUVORK5CYII=)\\n\\nIn recent months, AdaptixC2 has been adopted by various hacking groups, including threat actors tied to the Fog and Akira ransomware operations, as well as by an initial access broker that has leveraged CountLoader in attacks that are designed to deliver various post-exploitation tools.\\n\\nPalo Alto Networks Unit 42, which broke down the technical aspects of the framework last month, characterized it as a modular and versatile framework that can be used to \\&#8221;comprehensively control impacted machines,\\&#8221; and that it has been put to use as part of fake help desk support call scams via Microsoft Teams and through an artificial intelligence (AI)-generated PowerShell script.\\n\\nWhile AdaptixC2 is offered as an ethical, open-source tool for red teaming activities, it&#8217;s also clear that it has attracted the attention of cybercriminals.\\n\\nCybersecurity company Silent Push said RalfHacker&#8217;s GitHub bio about them being a \\&#8221;MalDev\\&#8221; triggered an investigation, allowing them to find several email addresses for GitHub accounts linked to the account&#8217;s owner, in addition to a Telegram channel called RalfHackerChannel, where they re-shared messages posted on a dedicated channel for AdaptixC2. The RalfHackerChannel channel has more than 28,000 subscribers.\\n\\n![CIS Build Kits](data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mP8Xw8AAoMBgDTD2qgAAAAASUVORK5CYII=)\\n\\nIn a message on the AdaptixFramework channel in August 2024, they mentioned their interest in starting a project about a \\&#8221;public C2, which is very trendy right now\\&#8221; and hoped \\&#8221;it will be like Empire,\\&#8221; another popular post-exploitation and adversary emulation framework.\\n\\nWhile it&#8217;s currently not known if RalfHacker has any direct involvement in malicious activity tied to AdaptixC2 or CountLoader at this stage, Silent Push said their \\&#8221;ties to Russia&#8217;s criminal underground, via the use of Telegram for marketing and the tool&#8217;s subsequent uptick in utilization by Russian threat actors, all raise significant red flags.\\&#8221;\\n\\nThe Hacker News has reached out to RalfHacker for comment, and we will update the story if we hear back.\\n\\nFound this article interesting?
