Alternative-explanation forensics

Alternative-explanation forensics is the rhetorical + analytical pattern of publishing a long-form post that deflates a malicious interpretation of an observed anomaly by (a) naming the narrative being critiqued, (b) walking through the forensic evidence, (c) proposing a more mundane (usually hygiene-failure) explanation consistent with the evidence, (d) naming the specific mechanism that would produce the observed data under the mundane hypothesis, and (e) stating honestly what you cannot determine.

Why publish when your read is "probably not malicious"

The instinct to publish is asymmetric: claims of malice tend to spread faster than claims of incompetence, especially when they fit a geopolitically-salient narrative. The silence that follows "we don't have a strong reason to believe this was an attack" leaves the malicious claim standing as the available explanation. Publishing an alternative — with the data and the domain expertise — corrects the record.

The recipe

  1. Name the narrative directly. "A cybersecurity newsletter flagged a route leak and posited intelligence- collection via MITM." Don't strawman.
  2. Enumerate the forensic signals. Each should be independently verifiable against public data.
  3. Propose a specific mechanism for the mundane hypothesis. Not just "probably a mistake" — a named config / policy / protocol-level failure that explains the observed behaviour.
  4. Address the newsletter's other claims (e.g. "Sparkle doesn't have RPKI ROV") with a technical distinction that explains why those claims, even if true, don't bear on the event.
  5. State honestly what you can't determine. Cloudflare: "Although it is impossible to determine definitively what happened on the day of the event..."
  6. Point forward. Name the mitigation that would have prevented the event regardless of intent (here: ASPA + RFC 9234 OTC + Peerlock).

Contrast with "public-attribution" posts

This pattern is Cloudflare's inverse to its 2025-08-04 Perplexity public-attribution post. That post makes a claim about a named operator's behaviour (Perplexity runs stealth crawlers) backed by a zero-confounder experiment. This post deflates a claim about a named operator's behaviour (AS8048 is not running an intelligence operation) backed by five forensic signals.

Both are Cloudflare's instinct to say "the public record deserves a considered reading of this event" — one direction makes the accusation, the other dissolves it. Same posture: treat public attribution as a published good.

Forensic evidence used in the 01-02 case

  • Recurrence pattern (11 leaks in a month — attacks rarely repeat that cleanly).
  • AS-relationship context (leaker is already on-path as provider — no MITM motive).
  • Prepending direction (nine prepends → push traffic away, opposite of attacker behaviour).
  • Temporal dispersion (multiple announcements over two hours — convergence pattern, not a single intentional event).
  • Timing vs. real-world trigger (>12 hours before the alleged political trigger).
