Attackers can steal encrypted data today and decrypt it once a large enough quantum computer exists. That's "harvest now, decrypt later". For incident responders, every exfiltration involving long-lived secrets is now a future disclosure risk too.
Find where RSA, ECC and Diffie-Hellman live: TLS, VPNs, code signing, PKI, backups, vendor products. Build a CBOM you can keep current.
Rank systems by how long their data must stay secret and how hard they are to change. Long-lived secrets and slow-to-replace systems go first.
Adopt ML-KEM and ML-DSA, often in hybrid mode alongside classical algorithms, and design systems so algorithms can be swapped without re-architecture.
Update IR playbooks: treat exfiltrated encrypted data as a future exposure, rotate keys with quantum-safe replacements, and log crypto posture.
SHA-256 evidence hashes remain sound. Digital signatures on long-lived reports and evidence packages should plan a move to post-quantum signatures.
Turn the timelines into budget, vendor requirements and milestones leadership can track, before regulators and customers ask.
Incident response planning, breach investigation, and a practical post-quantum migration roadmap: cryptographic inventory, risk ranking, and vendor questions.
Ransomware and BEC response, memory and log forensics, cloud and mobile evidence, and preserving digital evidence in the field.
Plain-language answers on legal holds, chain of custody, breach notification considerations, expert witnesses, and emerging quantum-readiness obligations.
