What this actually means
mit.edu recorded 10 fewer third-party requests in the visit configured for Brave-list blocking.
SBL-CORR-2026-001: The historical input-probe disclosure overstates coverage. Unload-only transmissions were not reliably recorded. Focus and blur handlers could run, and per-field failures were not fully counted. These reports cannot establish absence of input transmission outside their retained observations.
The scan observed signals a non-expert should not have to decode from raw request tables.
The cards below translate the evidence into plain language; severity reflects fixed reference thresholds, not measured population percentiles. The request log, domain table, and methodology remain below for verification.
75 requests observed in one controlled visit.
Worth checking
11 requests matched Brave Shields filter lists
11 requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser, while loading normally.
Computed with Brave's own ad-block engine and default filter lists in classification mode: matched requests were not blocked by the scanner and remain in this report's observed request counts. Matching shows what Shields would target on this visit's traffic; an actual Shields visit blocks these and also prevents their follow-on requests, so this number is neither a measured block count nor the total effect.
The hand-curated service catalog separately matched 11 request rows in this visit.Show matched requests
Nothing observed
Lower values observed across comparable metrics in the Brave-list blocking attempt
With the scanner configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit; application was not verified), this paired visit showed 10 fewer third-party requests and 9 fewer tracking-related service requests.
Services only seen in the unblocked visit: Google and Crazy Egg. The blocking visit's engine directly blocked 3 requests; the remaining difference may include follow-on requests that never started once their sources were blocked. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments), so treat this as an observed difference, not a measured blocking rate.
Signed per-metric differences between the two visits; nothing is summed across metrics.Show matched requests
Worth checking
1 first-party DNS alias matched tracking checks
Recorded DNS aliases resolve to catalogued tracking-related services: PostHog.
The scanner followed DNS CNAME chains from first-party subdomains and checked resolved targets against the service catalog and Brave filter lists. These matches do not establish a request's purpose, profiling, or an intent to conceal tracking. A filter-list match alone is not a verified service identity or proof of tracking.
Requests were dispatched to catalogued service domains
Google, Crazy Egg and Mailchimp appeared in the request log.
A catalog match identifies a maintainer-reviewed service/domain mapping; it does not establish why an individual request occurred, what it carried, or whether profiling happened. Functional catalog labels include analytics / tag management, advertising and session replay / behavior analytics. This scan could not identify 3 of the 12 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site. Catalog labels include session-replay or behavior-analytics services: Crazy Egg; the domain match alone does not prove that a recording occurred. The role taxonomy assigns these additional services explicitly non-tracking operational, support, security, consent-management, or hosting roles: Sentry.
The automated visit did not observe third-party cookies.
This does not prove the site never uses cookies; it means this visit did not observe third-party cookies.
5 cookies total in this report.No third-party cookies observed.
Context
Session-replay vendor observed
Crazy Egg appeared in the request log.
This is a behavioral instrumentation signal from listener registration, stack-attributed script origins, and known-vendor requests: it shows the page was instrumented to observe interaction, not that anything was transmitted. Stack attribution records the script origins present in the bounded registration call chain; a cross-site origin in that chain does not by itself establish that the cross-site script registered the listener, because first-party code can register its own listeners through a helper served from elsewhere. A different registrable domain is also not by itself a different operator: sites commonly serve their own scripts from a separate asset domain, so the card says third party only when the catalog or reviewed ownership attributes an origin to another organization. On scanners that run the active keystroke-capture probe, actual transmission is tested separately (a synthetic value is typed, never real input, and no typed values are collected); treat this card as a review prompt rather than proof.
known session-replay vendor(s): Crazy Egg
Nothing observed
No fingerprint-like API calls observed
The scan did not observe the instrumented high-entropy browser APIs.
This is an observation layer, not proof that fingerprinting is impossible.
0 API families recorded.
Brave Shields Comparison
No blocking → Brave-list blocking delta
No blocking: 5,032msBrave-list blocking: 5,255ms
Some deltas are not comparable across these two visits and are not shown.
Other detector and causal-path deltas (each visit's own evidence still renders below): v1 never recorded detector versions, so fingerprinting and pixel deltas cannot be proven to come from matching instrumentation.
The Shields-number delta (each visit's own evidence still renders below): The two visits measured different Shields quantities (filter-list matches vs engine-blocked requests), which must never share a delta.
Fingerprinting deltas (each visit's own evidence still renders below): At least one visit did not complete the fingerprint measurement, so no exact cross-visit delta is shown.
Ad-pixel deltas (each visit's own evidence still renders below): At least one visit did not complete the pixel measurement, so no exact cross-visit delta is shown.
Every signed change is Brave-list blocking minus No blocking. A positive or negative direction is descriptive, not a judgment that the result is better or worse.
Cookie and storage count deltas include every observation. Name-level lists show only reviewed names; unreviewed names are not itemized because they can contain identifiers.

Measurement limits
7 conditions affect how this evidence reads
This report
Brave-list blocking comparison runs should be collected under matched crawl conditions, and the blocking run is a simulation with Brave's engine and default lists in this scanner's browser, not a live Brave visit. Differences can still reflect timing, experiments, cache state, consent state, or bot detection.
The two visits ran in randomized order; the "Brave-list blocking" visit ran first.
Both visits
Each visit in this report is one automated, headless Chromium visit from a fixed en-US / UTC profile, with no scrolling, clicking, or consent interaction. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
Counts are a lower bound: trackers that load only after interaction or consent are not observed; Service Workers are blocked, and Web Worker or WebSocket traffic may be incomplete. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled. Cookie and storage figures are an end-of-visit snapshot, with storage keys read from the top frame only.
This scan typed a synthetic test value into 2 form fields (never submitting the form) to test whether typed input is captured and sent to third parties. The value is synthetic and is not stored. Requests the page sent during and after this typing, including any unload beacons, are part of the recorded request log and counts.
Resolved 1 first-party subdomain that is a CNAME alias for a third-party tracker (CNAME cloaking), which request-URL matching alone would miss.
Brave-list blocking visit only
Brave Shields block simulation was enabled; matching requests were aborted before loading and are not included in request totals.
How to use this report
Read the findings and measurement limits first, then inspect the evidence for each recorded visit. Comparisons include both visits, even where a difference cannot be interpreted.
Keep this PDF with its evidence package: the source JSON, correction context, export receipt and SHA256SUMS. The package preserves source bytes and the correction context at export time. Hashes check file consistency; they do not establish independent measurement accuracy or a signed attestation.

Request attribution map
Which actor each third-party request is attributed to, from the initiator the browser reported. Attribution, not causation: an initiator may itself have been told what to fetch, and requests with no reported initiator are not distinguished from ones fetched from several. Asterisks mark subdomain labels hidden for privacy.

Provenance
Exact build and instrument digests were not recorded by this legacy schema.
Recorded provenance is self-reported measurement metadata, not a cryptographic attestation. The public versioned report JSON contains the retained public evidence; see the methodology for interpretation and retention limits.
This report covers what the scanner measures, not everything a site can do. 17 browser surfaces are not instrumented at all (Every page except the one that was scanned; Anything that only loads after scrolling or interaction; Why a request happened, as a causal chain; and 14 others), 3 capabilities are declined by policy, and 3 are outside what any single visit can see. Their absence from this report is not evidence that they did not occur. Read the published coverage boundary.
Detector accuracy is unmeasured. No calibration study currently publishes a precision or recall for the detectors on this page, so a detector match here is a recorded observation, not a calibrated classification. How detector accuracy is measured.
Approved use boundary: This report is investigative evidence that requires independent corroboration. It is not a standalone legal determination and not the sole exhibit in a legal proceeding. Recorded in this project's release manifest on .
Reports record one automated visit per condition; visits may be incomplete. On restart-safe deployments, an interrupted visit may be retried; attempts are never merged. Results describe these visits, not everything a site can do.
