The infostealer week. Three credential-stealing families produced 2,946 Spyware-category IOCs — the dominant category — and one is a macOS-native stealer targeting the Apple Keychain, browser cookies and wallet files. Session-cookie theft and browser-credential theft were two of the week’s top-five MITRE techniques (stolen cookies bypass MFA). Phishing-kit output doubled week-over-week (+107%, 846 → 1,754 IOCs). A crypto-drainer sub-theme ran underneath (wallet-brand lookalike extensions + a prediction-market supply-chain script). Ransomware collapsed 83% (211 → 36 IOCs) — a leading-indicator lull, not an all-clear. 8,320 attributed IOCs. 72 named adversaries. 29 distinct MITRE TTPs. Full CISO briefing with 4 Sigma rules (incl. macOS Keychain + wallet-lookalike detection), top IOCs and risk-register wording.
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.
