Full teardown of the September 2026 NetScaler ADC/Gateway zero-day campaign: the ns_monuploadd_err.pl log-poisoning root cause analyzed line by line from firmware, the watchTowr DTLS heap-overflow PoC dissected down to its setcontext/ROP chain, and the complete payload landscape grounded in first-hand analysis of 18 in-the-wild campaign samples: the dual-mode webshell installers, update_c08937.pl with its plaintext passwords, the nsmon.pl cron bind shell no vendor named, Platypus enrollment certificates that date the C2 infrastructure to September 2, and a post-disclosure WHIPSHOT/SLAPSHOT copycat kit. With detection and eradication guidance.
