New DarkSword iOS exploit used in infostealer attack on iPhones

A new exploit kit for iOS devices and delivery framework dubbed “DarkSword” has been used to steal a wide range of personal information, including data from cryptocurrency wallet apps. DarkSword targets iPhones running iOS 18.4 through 18.7 and is linked to multiple actors, including UNC6353, suspected to be Russian, who used the Coruna exploit chain disclosed earlier this month. Researchers at mobile security company Lookout discovered DarkSword while investigating the infrastructure used for the Coruna attacks. Google’s Threat Intelligence Group and iVerify also collaborated for a more comprehensive analysis of this previously unknown threat and the adversaries leveraging it. iVerify's findings indicate that all flaws (sandbox escape, privilege escalation, remote code execution) exploited in this exploit chain are known or documented, and Apple has already addressed them in the latest iOS releases. The DarkSword exploit kit uses six vulnerabilities tracked as CVE-2025-31277, CVE-2025-43529, CVE-2026-20700, CVE-2025-14174, CVE-2025-43510, and CVE-2025-43520. In a report today, Google Threat Intelligence Group (GTIG) says that DarkSword has been used since at least November 2025 by several threat actors, who deployed three separate malware families: The first adversary observed using the exploit chain is UNC6748, in attacks targeting Saudi Arabian users via a website impersonating Snapchat. GTIG says that in late November 2025, DarkSword was used in Turkey, in activity assoc...
