TL;DR

In February 2012, Jonathan Mayer, a PhD candidate at Stanford Law School and Stanford CS, together with Wall Street Journal journalists (Julia Angwin), revealed that Google had deliberately circumvented the default privacy settings of the Safari browser on iPhones, iPads, and Mac computers. Safari was at the time the only mainstream browser that blocked third-party cookies by default (third-party cookies used for tracking). Google exploited a technical loophole — an exception in Safari that allowed cookies after a “user interaction with a form” — by inserting invisible auto-submitting HTML forms into ads served through its DoubleClick network. Safari interpreted the automatic form submission as user interaction and accepted the cookie. The consequence: Google tracked millions of iPhone users despite their privacy settings, while on Google’s “Advertising Help” page it publicly boasted about respecting Safari’s settings.

August 2012 — the FTC imposed a then-record $22.5 million penalty for violating the 2011 Consent Decree. November 2013 — 37 US states closed a joint settlement of $17 million. In the UK, the Lloyd v. Google case got underway (a class action on behalf of 4.4 million Britons), intended as a test of whether British law permitted class actions over privacy violations. On November 10, 2021, the UK Supreme Court rejected the lawsuit on procedural grounds — effectively blocking data-protection class actions in the UK for years.

The case triggered a cascade of reforms on Apple’s side. Safari gradually introduced ever more robust mechanisms: Intelligent Tracking Prevention (ITP) in 2017, Full Third-Party Cookie Blocking in 2020, App Tracking Transparency (ATT) in iOS 14.5 (2021). These changes cost Google and Meta billions of dollars in advertising revenue — in 2022, Meta alone announced a revenue decline of ~$10 billion per year solely due to ATT. This shows how a single case with a $22.5 million penalty can initiate structural changes at a scale of tens of billions.

After the discovery, Mayer built a career as a regulator: Chief Technologist of the FCC Enforcement Bureau, November 2015 – March 2017; 2024–2025 Chief Science and Technology Adviser and Chief AI Officer at DOJ. Ashkan Soltani became Executive Director of the CPPA from October 4, 2021 (selected September 27, 2021). In November 2024 the CPPA announced his departure; Tom Kemp took over as successor from March 2025 — the most powerful privacy regulator in the US.

Mechanism

How it worked — technical architecture

Safari context. In 2011, Safari was the only mainstream browser that blocked third-party cookies by default. Chrome, Firefox, and Internet Explorer accepted everything. Blocking third-party cookies is a key safeguard: advertising trackers (DoubleClick, Facebook Pixel, AdSense) embed in sites A, B, C and can track a user via the same cookie across every site. Blocking third-party cookies breaks that mechanism.

The Safari loophole (intended as an exception). Apple’s engineers were aware that a complete block on third-party cookies would break legitimate use cases such as OAuth login (log in with Facebook, log in with Google), online payments (log in with PayPal), and some embeddable forms. They therefore introduced an exception: if a user interacts with a form on a third-party origin (clicks submit), Safari accepts the cookie. The reasoning: the user is knowingly engaging with that external domain.

The Google/DoubleClick exploit. Google added invisible HTML/JavaScript code to DoubleClick ads:

<iframe src="ad.doubleclick.net/..." style="display:none; height:0; width:0">
  <form action="https://googleads.g.doubleclick.net/..." method="POST">
    <input type="hidden" name="track" value="1" />
  </form>
  <script>
    document.forms[0].submit();
  </script>
</iframe>

When a user visited a page with a DoubleClick ad:

  1. The ad loaded in a hidden frame (display:none, 0x0 px).
  2. JavaScript automatically clicked submit on the invisible form.
  3. Safari interpreted this as “user interaction with a form” and accepted the DoubleClick cookie.
  4. The cookie was persistent (not session), valid for 2 years, used for cross-site tracking.

Consequence:

  • Millions of Safari users were tracked despite their default privacy settings.
  • Every DoubleClick ad on any page “implanted” a cookie.
  • Google publicly boasted on its “Advertising Help” page that it respected Safari’s settings: “if you haven’t changed your default Safari settings, your browser already blocks third-party cookies. No additional action is required by users to opt out of personalized advertising from Google.” That page had to be quickly revised after the WSJ publication.

Why this was a heavyweight case

  • Violation of the 2011 FTC Consent Decree — Google had only one year earlier entered into an agreement with the FTC committing not to mislead. This was the first formal violation of the Consent Decree, which increased the legal gravity.
  • Technical character — not a “bug,” not a “lone engineer” (as in Street View Wi-Spy), but a deliberate production implementation hidden in the JavaScript layer of ads.
  • Systemic scaleall Safari users were affected, that is, nearly all iPhone users globally.

Discovery

Who is Jonathan Mayer

Jonathan Mayer (year of birth not publicly disclosed) — an American computer scientist and lawyer specializing in digital privacy. Education: Princeton (BA Computer Science), Stanford Law School (JD), Stanford CS (PhD). From 2011 to 2013 he was a PhD candidate at Stanford running the Web Privacy Census project — the automated scanning of millions of sites for trackers. His methodology (OpenWPM, FourthParty) became the standard in web privacy research.

After revealing the Safari Workaround: Chief Technologist of the FCC Enforcement Bureau (November 2015 – March 2017), then in 2024–2025 Chief Science and Technology Adviser and Chief AI Officer at DOJ. He is currently an assistant professor at Princeton.

Additional accomplishments:

  • Co-author of the Do Not Track (DNT) standard (2010–2011)
  • Co-author of “The Web Never Forgets” (2014) — research on fingerprinting via the Canvas API
  • Co-author of research showing that phone metadata is sufficient to identify a person’s health status, religion, and sexual orientation (2014, an argument in the NSA debate)

How the disclosure came about

Mayer discovered the anomaly while running Web Privacy Census 2012. His scripts automatically scanned the top 1000 websites and counted cookies of every type. He noticed that in the Safari browser the number of DoubleClick cookies was disproportionately high relative to expectations (blocking third-party cookies should significantly reduce the count). Reverse-engineering analysis of the DoubleClick ad code revealed the iframe + form + auto-submit trick.

Mayer contacted Julia Angwin of the Wall Street Journal, who was running the “What They Know” series — a multi-month investigation into online trackers. Together with Angwin, Jennifer Valentino-DeVries, and Ashkan Soltani, he verified the findings. Publication on February 17, 2012.

First publications

  • February 17, 2012 — Julia Angwin, Jennifer Valentino-DeVries, “Google’s iPhone Tracking,” The Wall Street Journal
  • February 17, 2012 — Jonathan Mayer, “Web Policy: Safari Trackers” — a Stanford CIS technical report

Key people

Discoverers

  • Jonathan Mayer — described above.
  • Ashkan Soltani — independent security and privacy researcher, former Google employee, later Chief Technologist of the FTC, Executive Director of the California Privacy Protection Agency (CPPA) from October 4, 2021 (selected September 27, 2021). In November 2024 the CPPA announced his departure; Tom Kemp took over as successor from March 2025. The CPPA — the most important privacy regulator in the US — enforces the CCPA and CPRA.
  • Julia Angwin — a privacy journalist. Founder of The Markup (2019), editor at ProPublica (2014–2018), author of the books “Dragnet Nation” (2014) and “Stealing MySpace” (2009). Sued and harassed by a pesticide dealer in 2012 over an article about the pesticide DBCP; she refused to settle. Pulitzer nominee.
  • Jennifer Valentino-DeVries — formerly WSJ, today NYT; specializes in investigative digital analytics.

Regulators

  • FTC — Chairman Jon Leibowitz (2012) at the time of the $22.5 million penalty.
  • Eric Schneiderman — Attorney General of New York, coordinator of the 37-state action.
  • UK ICO — engaged informally, did not impose a penalty (reasoning: lack of jurisdiction + “no substantial harm,” analogously to Wi-Spy).

Lawyers

  • Richard Lloyd — former director of Which? (the British consumer organization), represented 4.4 million UK iPhone users in Lloyd v. Google.
  • Hugh Tomlinson KC — represented Lloyd at the UKSC; one of Britain’s leading human-rights and privacy lawyers.

Google

  • David Drummond — at the time Chief Legal Officer of Google; author of the public responses.
  • Ginny Marvin — Google PR.

Company response

Google

February 17, 2012 (the same day as the WSJ publication) — Google immediately stopped the practice. Official statement:

“The Journal mischaracterizes what happened and why. We used known Safari functionality to provide features that signed-in Google users had enabled. It’s important to stress that these advertising cookies do not collect personal information.”

Google’s defense:

  1. The Safari form exception is “known functionality,” not a loophole.
  2. They used it for “features that signed-in Google users had enabled” — e.g., +1 buttons (the predecessor of Like).
  3. DoubleClick cookies did not contain “personal information.”

Why the defense collapsed:

  1. The 2011 FTC Consent Decree prohibited misrepresentation regarding privacy. On its “Advertising Help” page, Google boasted about respecting Safari’s settings — while in the ad code it was deliberately circumventing them. That was classic misrepresentation.
  2. The mere fact that a cookie “does not contain PII by itself” does not mean it is not personal data — it can be used as an identifier tracking a user across sessions.
  3. The practice was significant for DoubleClick advertising (millions of identified users), not just for the niche +1 feature.

Settlements (2012, 2013) — Google did not admit guilt (the “neither admit nor deny” formula), paid $22.5M to the FTC + $17M to the states, and committed to consumer education.


Jurisdictions

  1. US federal — FTC
  2. US states — 37 states in a coordinated action
  3. United Kingdom — Lloyd v. Google, rejected 2021
  4. A series of EU investigations — did not end in penalties (pre-GDPR, harder to enforce)
  • FTC Consent Decree 2011 — the main basis for the $22.5M penalty
  • FTC Act § 5 — unfair/deceptive practices
  • State consumer protection laws (37 states)
  • UK Data Protection Act 1998 — the basis for Lloyd v. Google
  • ePrivacy Directive art. 5(3) — cookies require consent

Precedents and implications

For US law

  • The $22.5M FTC record — in 2012, the largest penalty in the agency’s history; after Cambridge Analytica it looks minor, but at the time it was a breakthrough.
  • A precedent for enforcing Consent Decrees — Google was the first company to pay for violating an FTC Consent Decree.
  • Ashkan Soltani at the CPPA — shows that whistleblowers/researchers can become regulators and close the loop.

For UK law

  • Lloyd v. Google UKSC 2021 — a negative precedent. It de facto abolished class actions in data protection in the UK. The problem: every claimant has to demonstrate individual harm. For millions of people harassed by cookies, that is practically impossible.
  • Data Protection and Digital Information Bill (2024) — a partial reform.

For Big Tech practice and Apple

  • The Apple vs Google escalation — the Safari Workaround is a point of no return. Apple strategically decided to differentiate itself from Google through privacy. The subsequent steps:
    • 2017: ITP 1.0 (Intelligent Tracking Prevention) — automatic expiration of cookies
    • 2019: ITP 2.x — Storage Access API
    • 2020: Full Third-Party Cookie Blocking
    • 2021: App Tracking Transparency (ATT) — users must consciously consent to tracking
  • ATT cost Meta ~$10 billion per year (announcement in 2022).
  • Chrome third-party cookie deprecation — announced for 2024, repeatedly postponed, and now reversed in 2024 in favor of the “Topics API” and user choice.

Conclusions for citizens

What does this mean for me?

If in 2011–2012 you used an iPhone, MacBook, or iPad and browsed the internet — Google was likely tracking you despite your privacy settings. Today the situation is better thanks to Apple’s reforms, but advertisers are constantly looking for new ways to bypass safeguards. The example from A01: Meta’s “Local Mess” is essentially a next-generation Safari Workaround — a different trick, the same goal.

How can I protect myself?

  1. Use Safari on iPhone — it has the strongest protection against tracking (ITP, ATT). Chrome on iOS under the hood uses Safari (WebKit) with additional Google trackers.
  2. On desktop use Firefox with Enhanced Tracking Protection or Brave (which blocks trackers by default). Firefox has Total Cookie Protection — it isolates cookies per-site.
  3. Install uBlock Origin — the most effective blocker (Firefox, Edge). In Chrome it is constrained by Manifest V3 (since 2024).
  4. Review iOS privacy settings — Settings → Privacy & Security → Tracking. Turn off “Allow Apps to Request to Track” (this will block ATT prompts at startup).
  5. In the Safari browser — enable “Prevent Cross-Site Tracking” (Settings → Privacy).
  6. Use Private Relay (iCloud+) on iOS — it hides your IP from trackers.
  7. Dark patterns in cookie banners: if a site does not offer an equally prominent “Reject All” (as visible as “Accept All”), it violates GDPR and ePrivacy. You can report it to your DPA.

What rights do I have?

In the EU:

  • ePrivacy Directive art. 5(3) — third-party cookies require prior, informed consent.
  • GDPR art. 6 — processing of data (including from identifying cookies) requires a legal basis.
  • GDPR art. 7 — consent must be freely given, specific, informed, and unambiguous.

In the UK (after Lloyd v. Google):

  • Individual lawsuits are still possible (not class actions).
  • The ICO can impose penalties — in 2024 a reform was enacted that partially restores class actions.

Where to report?

  • Poland: UODO
  • Cookie banners without an equivalent refusal option: can be reported to UODO and NOYB (noyb.eu)
  • Consumer protection: UOKiK for deceptive interfaces

A note for mediators, lawyers, website owners

If you run a website for a law firm, foundation, or company:

  • Your cookie banner must have equivalent “Accept” and “Reject” options (equally visible and clickable).
  • Using Google Analytics in the EU has been challenged since 2022 (several DPAs, including the Austrian, Dutch, and French, have found that it violates the GDPR through transfers to the US). Alternatives: Matomo (EU-hosted), Plausible Analytics, Fathom.
  • Fashion ID (CJEU C-40/17) — if your site has a Facebook Like button, you are a joint controller of the data collected by Meta. This means joint liability.

Context

  • Jonathan Mayer — the discoverer of the Safari Workaround — later became Chief Technologist of the FCC Enforcement Bureau (November 2015 – March 2017), and in 2024–2025 Chief Science and Technology Adviser and Chief AI Officer at DOJ. A classic case of “switching sides”: researcher → regulator → researcher. A rare pattern in the privacy world.
  • “Do Not Track” (DNT) — a standard that Mayer co-authored (2010–2011). Google never implemented respect for DNT in its ads. One of the reasons Mayer took up the publication: “If Google doesn’t respect DNT, it’s interesting how it respects other privacy settings…”.
  • Ashkan Soltani → California — he became Executive Director of the CPPA (California Privacy Protection Agency) from October 4, 2021 (selected September 27, 2021), the strongest privacy regulator in the US. The CPPA enforces the CCPA and CPRA. Soltani started out as an independent researcher, worked with WSJ on the Safari Workaround, then joined the FTC, then the CPPA. In November 2024 the CPPA announced his departure; Tom Kemp took over as successor from March 2025.
  • Internet Explorer was also affected — shortly after the WSJ, Microsoft announced that Google was using analogous techniques in IE (a trick with the P3P Policy tag, used improperly). Google confirmed it (“P3P is outdated, we didn’t take it seriously”), but it triggered additional negative PR.
  • The $22.5M FTC penalty was an FTC record in 2012 — today, after the $5 billion Cambridge Analytica penalty, it looks nominal. But in 2012 it was the agency’s greatest achievement.
  • Google’s stock rose after the penalty — investors interpreted $22.5M as one day’s revenue for Google (which in 2012 was about $37 billion a year, or ~$100 million a day).
  • Google did not admit guilt — a “neither admit nor deny” settlement. A standard corporate strategy in the US.
  • The symbolic scale of the FTC $22.5M penalty vs Google’s 2012 revenue ($37B) = 0.06% of revenue. For comparison: a GDPR privacy penalty for a citizen can reach 4% of revenue (5% of personal income). Big Tech in 2012 de facto had lower penalty thresholds than citizens.
  • Apple vs Google — a defining rivalry: the Safari Workaround radicalized Apple. Steve Jobs in 2010 in an interview with All Things Digital emphasized that “privacy means people know what they’re signing up for, in plain English”. After 2012, Tim Cook turned privacy into a strategic brand difference for Apple — ad lines like “Privacy. That’s iPhone.
  • The Meta ATT hit: $10 billion a year — Apple’s App Tracking Transparency (April 2021) cost Meta about $10 billion in declining advertising revenue per year (announcement in 2022). Zuckerberg publicly harshly criticized Apple. Apple’s strategic response had begun many years earlier — with the Safari Workaround.
  • Chrome and Manifest V3 — since 2024 Chrome has restricted ad-blocking extensions (Manifest V3). uBlock Origin is available in a limited version on Chrome. This is the opposite of Apple’s direction: Google defends the advertising model, Apple attacks it in the name of privacy.
  • Polish context — “Fashion ID” — a 2019 CJEU ruling concerning owners of sites with a Facebook Like button. The case was originally German (Verbraucherzentrale NRW). The ruling has direct significance for Polish online stores, blogs, and public institutions: if you have a Facebook Like button, you are a joint controller.
