The Uber Data Breach Cover-Up (2016)



In 2016, Uber, the global ride-sharing giant, suffered a major data breach that exposed the personal information of 57 million individuals, including riders and drivers worldwide. Instead of reporting the incident as required by law, Uber paid hackers $100,000 to conceal the breach, disguising the payment as a bug bounty reward.

This cover-up had significant legal, ethical, and cybersecurity implications, culminating in lawsuits, fines, and criminal charges—marking a historic moment in the enforcement of corporate cybersecurity responsibilities.


What Was Breached?

The attackers accessed:

  • Personal information of 57 million users, including:

    • Full names

    • Email addresses

    • Phone numbers

  • Driver-specific information (approximately 600,000 U.S.-based Uber drivers):

    • Full names

    • Driver’s license numbers

Notably, Uber stated that no Social Security numbers, credit card information, trip location data, or other personal details were accessed. However, the data that was stolen was still significant enough to facilitate identity theft and targeted phishing.


How the Breach Happened

Uber's GitHub repositories played a key role:

Private GitHub Repositories Leaked:

  • The attackers accessed Uber's private GitHub repository, where Uber engineers stored code.

  • Poor access controls led to hardcoded credentials being stored in the codebase.

AWS Credentials Exposed:

  • These GitHub-stored credentials were used to access Uber’s AWS S3 buckets (Amazon Simple Storage Service), where sensitive user data was stored.

Data Downloaded:

  • The hackers exfiltrated a 57-million-record data dump, downloaded from Uber's AWS account.

Ransom Demand:

  • The attackers contacted Uber, demanding a ransom in exchange for deleting the data.


Timeline of Events

Date Event
October 2016 Breach occurs; Uber is informed by the attackers.
Late 2016 Uber, under CSO Joe Sullivan, pays $100,000 to hackers via bug bounty platform HackerOne.
November 2017 New CEO Dara Khosrowshahi discovers the breach and cover-up; publicly discloses the breach.
November 2017 Uber fires CSO Joe Sullivan and his legal deputy.
September 2018 Uber agrees to a $148 million settlement with 50 U.S. states + D.C.
August 2020 Joe Sullivan is charged with obstruction and misprision of a felony.
October 2022 Joe Sullivan is convicted on both charges.
May 2023 Sullivan is sentenced to probation, avoiding prison time.

Legal Fallout

Uber’s Corporate Penalties:

  • $148 million settlement with all U.S. states and Washington, D.C., for violating state data breach notification laws.

  • Uber agreed to implement:

    • Independent third-party audits of its privacy practices.

    • A new data security program.

    • More transparent bug bounty procedures.

Criminal Case: U.S. v. Joseph Sullivan

  • Joe Sullivan, Uber’s former Chief Security Officer, was indicted in 2020.

  • Charges:

    • Obstruction of justice (for concealing the breach during FTC’s investigation into Uber's 2014 data breach).

    • Misprision of a felony (failing to report a felony to authorities).

  • In October 2022, Sullivan was found guilty.

  • In 2023, he was sentenced to 3 years of probation, avoiding prison, largely due to his previous public service and support from cybersecurity professionals.


Ethical Concerns and Cybersecurity Lessons

Bug Bounty Misuse

  • Uber attempted to legitimize the payment by routing it through HackerOne, its bug bounty platform.

  • This violated the norms of ethical hacking:

    • Bug bounties are for good-faith disclosures—not extortion or data theft.

    • The hackers were not vetted researchers and demanded payment after committing a crime.

Transparency Failure

  • Uber failed to notify affected individuals or regulators.

  • This violates basic principles of cybersecurity incident response and data protection regulations.

Poor Credential Management

  • Sensitive AWS credentials were hardcoded and stored in GitHub—an avoidable risk with proper secrets management.

FTC Investigation Obstruction

  • Uber was under investigation by the Federal Trade Commission (FTC) for a 2014 breach when the 2016 breach occurred.

  • Uber did not disclose the new breach to the FTC, further compounding legal consequences.


Key Takeaways for Cybersecurity Professionals

  • Report breaches immediately – Full transparency with authorities and users is essential for compliance and trust.

  • Implement strict secrets management – Never store credentials in code repositories.

  • Vet and properly structure bug bounty programs – Ensure they are never misused to conceal criminal actions.

  • Have a formal incident response plan – Involve legal, security, and executive stakeholders.

  • Compliance with data protection laws is non-negotiable (e.g., GDPR, CCPA, state laws).


The Uber breach and its cover-up marked a watershed moment in cybersecurity history. It showed how mismanagement, secrecy, and ethical failures can lead to serious legal and reputational damage. The criminal conviction of a corporate security officer also sent a chilling message across the cybersecurity field: accountability now has real personal consequences.

As the digital landscape becomes more complex, the Uber case is a powerful reminder of the need for ethical leadership, clear breach response procedures, and robust security practices.
