The burn-out week. Ransomware operators collapsed 94% in seven days (36 → 2) as the new-affiliate cohort completed its deployment phase. Two Mozi-class botnet operators produced 1,169 indicators in a parallel infrastructure build event. 19 malware families produced the largest Malware-tier reading of the trailing 8 weeks. APT concurrency ticked up (4 → 5) — early recovery signal. 4,812 attributed IOCs. 51 named adversaries. 19 distinct MITRE TTPs. Full CISO briefing with 4 Sigma rules, top 60 IOCs, risk-register wording.
The pivot week. The three-week persistent C2 operator surfaced zero attributable indicators. The ransomware surge we forecast for Weeks 40-42 arrived one week early at 37 concurrent operators (208% jump). APT concurrency collapsed to 4 clusters, confirming cycle-end. Malware distribution surface exploded with three concentrated Loader/RAT/Trojan clusters. Full CISO briefing with 4 Sigma rules, top 60 IOCs, risk-register wording.
29 concurrent APT / Threat-Actor clusters — highest concurrency in months. 1,033 phishing-kit IOCs from just 4 concentrated kits. 3,150 unique high-confidence IOCs across 101 clusters. Domain-tier attribution now dominant. Volume down 47% but concentration and sophistication up. Full weekly briefing with 4 Sigma rules and 3 hunt queries.
