The research, later detailed at Black Hat 2026, describes how an attacker can chain vulnerabilities across preinstalled Samsung applications to gain system-level access on devices including the Samsung Galaxy S25, S24, and Flip 7. The chain requires victim interaction with a malicious link, which triggers a sequence of forced redirects through the Samsung Members and Samsung Account applications. By exploiting an XSS vulnerability, the attackers gained unauthorized access to the Bixby 'Capsule' infrastructure - a hidden background service used for voice command processing. Accessing these Capsules allowed for data exfiltration and the attainment of system-level privileges, enabling remote code execution on the targeted Android smartphones. Samsung issued patches for Samsung Members in November 2025 and for Samsung Account in December 2025.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker lures the victim into clicking a malicious link via web advertising or a messaging application.\u003c/li\u003e\n\u003cli\u003eCVE-2025-21079 is triggered upon link interaction, forcing the Samsung Members application to navigate to an attacker-controlled website.\u003c/li\u003e\n\u003cli\u003eThe malicious website forces the Samsung Members application to trigger the Samsung Account application.\u003c/li\u003e\n\u003cli\u003eCVE-2025-58486 is exploited within the Samsung Account application to force it to connect to an attacker-controlled malicious domain.\u003c/li\u003e\n\u003cli\u003eThe attacker exploits an XSS vulnerability (CVE-2025-58487) within the Samsung Account application context.\u003c/li\u003e\n\u003cli\u003eThe XSS execution is used to interact with a specific, restricted Bixby entry point for which Samsung Account holds special permissions.\u003c/li\u003e\n\u003cli\u003eThe attacker interacts with the Bixby Capsule infrastructure to bypass internal command restrictions.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves system-level permissions on the Android device, facilitating full device control and data exfiltration.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe exploit chain allows for remote system-level compromise, the highest privilege level on consumer Android devices. Successful exploitation enables attackers to achieve remote code execution, exfiltrate sensitive user data, and gain persistent control over the device. While demonstrated on flagship Galaxy S25, S24, and Flip 7 models, the researchers noted the vulnerability affects older Samsung devices that may lack the patches released by the manufacturer in late 2025.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure all Samsung mobile devices are updated to the latest security firmware provided by the manufacturer to include the patches for CVE-2025-21079, CVE-2025-58486, and CVE-2025-58487.\u003c/li\u003e\n\u003cli\u003eImplement mobile device management (MDM) policies to enforce OS and application updates across the enterprise mobile fleet.\u003c/li\u003e\n\u003cli\u003eEducate users regarding the risks associated with clicking suspicious links received through unverified messaging channels or advertisements on mobile devices.\u003c/li\u003e\n\u003cli\u003eAudit and restrict permissions granted to preinstalled system applications if the mobile management platform supports granular configuration.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-08-05T20:28:04Z","date_published":"2026-08-05T20:28:04Z","id":"https://feed.craftedsignal.io/briefs/2026-08-samsung-bixby-exploit/","summary":"Researchers demonstrated a $50,000 exploit chain utilizing three vulnerabilities in Samsung Members, Samsung Account, and Bixby to achieve remote system-level code execution on flagship Galaxy devices.","title":"Exploit Chain Leading to System-Level Compromise on Samsung Mobile Devices","url":"https://feed.craftedsignal.io/briefs/2026-08-samsung-bixby-exploit/"}],"language":"en","title":"CraftedSignal Threat Feed - Galaxy Flip 7","version":"https://jsonfeed.org/version/1.1"}
