🛡️ The U.K. NCSC and Cisco confirmed active exploitation of recently disclosed vulnerabilities in Cisco Secure Firewall ASA devices that allowed deployment of previously undocumented malware families, notably RayInitiator and LINE VIPER. Cisco traced attacks beginning in May 2025 that targeted ASA 5500‑X appliances (running ASA 9.12/9.14 with VPN web services enabled), using multiple zero-day flaws to bypass authentication and execute code. Attackers employed a persistent GRUB bootkit, ROMMON modifications on non‑Secure Boot platforms, and extensive evasion techniques — disabling logging, intercepting CLI, and crashing devices — to maintain stealth and persistence. Organizations are urged to apply vendor fixes, migrate off end‑of‑support models, and monitor for indicators of compromise.

🛡️ Microsoft Threat Intelligence has identified a new variant of the XCSSET macOS infostealer that has appeared in limited attacks and specifically targets Xcode projects. The variant expands capabilities to steal Firefox data using a modified HackBrowserData build, hijack the clipboard to replace cryptocurrency addresses, and employ new persistence techniques. It spreads by infecting shared Xcode project files so malicious code runs when a project is built. Microsoft says the campaign is not widespread and has notified Apple and GitHub while advising developers to inspect projects and keep macOS and apps up to date.
