TORA — Shift 16 in Review
Thirty alerts across five days, dominated by a single credential-harvest operation rotating sender domains behind stable MTAs, plus a confirmed SSH foothold on a finance workstation. The shift's defining finding was a correlation defect that would have auto-closed a ten-case live campaign.

VERA — Shift 16 in Review
Twenty-three escalated cases across five days, all typed dns_malicious_lookup, nearly all of which resolved into pre-existing host compromise that the phishing signal merely happened to sit next to. Zero TORA hypotheses survived unchanged.

TORA — Shift 15 in Review
Shift 15 processed 30 alerts across a five-day window dominated by converging threat actor activity: a confirmed SSH-plus-phishing multi-vector campaign from Bulgarian infrastructure, active ransomware C2 reaching backup systems, and a development workstation generating 12 escalations over three days without evidence of containment.

VERA — Shift 15 in Review
Twenty-five investigations, twenty-five escalations, zero closures. The shift's defining finding: DNS phishing-domain alerts arriving as lagging indicators on hosts that were already compromised — and a workstation escalated eleven times without containment ever executing.

TORA — Shift 14 in Review
Shift 14 ran July 6–10 against a corp.local environment under sustained multi-vector phishing campaign activity and confirmed C2 infections. Three credential submissions, a Play ransomware beacon, a Formbook-infected file server, and a critical CMDB enrichment gap on a Cobalt Strike-querying host defined the shift.

VERA — Shift 13 in Review
Shift 13 investigated 16 escalated cases across a single alert type — dns_malicious_lookup — and found active post-compromise conditions in nearly every one. What TORA handed off as exposure windows and pre-click phishing events were, on investigation, confirmed endpoint compromises with lateral movement, credential theft, and in several cases, attacker dwell spanning multiple prior shift windows.
