Annual India Edition 2026

The 2026 Threat-Intel Calendar — India edition.

A month-by-month read of the regulatory beats, adversary cadence, and seasonal patterns Indian defenders should plan against in 2026 — across nine critical sectors. Not a prediction of when specific incidents will land. A planning artefact, corrected monthly as the year unfolds.

How this calendar works

It is a planning framework, not a forecast. Five inputs are knowable a year out.

01 · Deterministic

Regulatory beats

CERT-In, SEBI, RBI, IRDAI, MeitY, DoT and CEA publish their dates. We surface them; we do not invent them.

02 · Statistical

Seasonal patterns

Festive UPI fraud, ITR-refund phishing, exam-result lures, IPL scams — multi-year curves, anchored to RBI and CERT-In data.

03 · Reactive

Adversary cadence

APT36, SideCopy, TAG-38 / RedEcho, Lazarus, MuddyWater. Operational tempo from Mandiant, Talos, Recorded Future, ESET, Seqrite.

04 · Cyclical

Vendor patch cadence

Patch Tuesday, Oracle's quarterly CPU, Cisco semi-annual, and the monthly Siemens and Schneider ProductCERT drops. The vendor calendar is public — plan to it.

05 · Corrected

Monthly revisions

Every month, we mark what landed against what was forecast, and reissue the calendar with corrections. No prophecy required.

The month at a glance

  1. Year-end fraud window — KYC-expiry SMS lures and “tax-saving” scams.

    80C and ELSS deadline week drives the salaried-professional target list.

  2. FY 26-27 H1 disclosure window for listed entities.

    Verify CSCRF / ITGRCA / IRDAI audit-cycle completion before year-end.

  3. Plan the 2027 calendar from December’s RBI Financial Stability Report.

    The annual aggregates land in May 2027; FSR gives the leading indicator now.

Caveats & sources

Read these before you act on the calendar.

Editorial constraints

  • Not a forecast. Specific incidents on specific dates are not predictable. The calendar surfaces elevated-probability windows from deterministic, statistical and reactive inputs.
  • Anniversary correlation is reactive. CTI vendor data supports India-Pakistan and India-China APT reactivity to events, not fixed-date anniversary spikes.
  • Denied breaches are flagged as such. CoWIN (Jun 2023), ICMR (Oct 2023) and Airtel (Jul 2024) were officially denied; we cite the claim window, not the scope.
  • Water and Transport are under-disclosed. Indian utilities and transport operators rarely publish incident detail. Absence of data is not absence of risk.
  • Budget-day and salary-day patterns are behavioural hypotheses, widely cited in vendor research but not isolated in RBI or CERT-In time-series data.
