Notepad++ Update Hijack Linked to Hosting Provider Breach
🔒 A months-long supply chain attack redirected update traffic for notepad-plus-plus.org to attacker-controlled servers, enabling malicious manifests to be served to the built-in WinGUp updater and, in some cases, pointing users to compromised executables. Investigators conclude the intrusion stemmed from a compromise of the shared hosting provider infrastructure rather than a flaw in the Notepad++ code. Logs suggest the breach began in June 2025, with direct server access ending on 2 September 2025 while exposed credentials lingered until 2 December 2025.
