At The Edge Clear: April 13 - 20, 2026

Summary: GreyNoise recorded roughly 6.2 million sessions across hundreds of source IPs probing for exposed ENV files, .git/config, AWS metadata, and path traversal between April 13 and 20, 2026. Port 5900 (VNC) drew 17,375,937 sessions, third-most-targeted behind SSH and SMB, with RFB protocol traffic at 4,305,556 sessions and VNC authentication tags nearly empty, indicating exposure mapping rather than password guessing.

Key Takeaway: Three IPs on VPSVAULT.HOST LTD in Brazil pushed 3,352,578 sessions carrying 18+ exploits, including newly weaponized CVE-2025-54322 (Xspeeder SXZOS RCE, CVSS 10.0), and a confirmed Mirai node added 851,713 Telnet default-credential stuffing sessions - so an exposed config file or a default password on an internet-facing device is the entry point these operators are already testing.
