What happened
SANS ISC reports widespread brute‑force scanning activity targeting CrushFTP instances. This follows multiple high‑impact flaws in CrushFTP — including a template‑injection RCE (CVE-2024-4040), an authentication bypass handing over the crushadmin account (CVE-2025-31161), and an actively exploited July 2025 zero‑day (CVE-2025-54309). The diary set also notes other items of interest (Wireshark 4.6.4 addressing vulnerabilities, phishing delivering malware via fake FedEx notifications, and RTF/ZIP analysis tips). Immediate actions: patch/update CrushFTP, enforce strong/rotated credentials and MFA
