Article summary: Hackers are reportedly using a two-step chain: first they gain initial access on exposed F5 BIG‑IP APM devices through a remotely exploitable flaw such as CVE‑2025‑53521, then they use Linux local privilege-escalation bu. Topic tags: general, government, education, documentation, general web. Reference image context from search candidates: Reference image 1: visual subject "A local privilege escalation (LPE) vulnerability, dubbed Copy Fail (CVE-2026-31431), has been identified in the Linux kernel's `authencesn` cryptographic template. This logic flaw" source context "Weekly Threat Bulletin – May 6th, 2026 | F5 Labs" Reference image 2: visual subject "# CVE-2026

企業網絡入侵手法近年出現一個明顯趨勢:先攻破對外的安全設備,再利用 Linux 系統漏洞升權,最後橫向移動到內部核心系統。安全研究顯示,攻擊者會先入侵公開在互聯網上的 F5 BIG‑IP Access Policy Manager (APM),之後再利用 Linux kernel 的本地權限提升漏洞,例如 Copy Fail 或 Dirty Frag,取得 root 權限並深入企業網絡。
