Mercor Data Breach Lawsuit Investigation
Received a June 2026 breach notice from Mercor?
Dapeer Law, P.A. is investigating a potential class action against Mercor.io Corporation, a San Francisco-based artificial intelligence company, on behalf of the experts, contractors, and other individuals whose personal information may have been exposed in the March 2026 cyber incident.
Who may qualify
You may be eligible to participate in a class action if any of the following applies:
- You received a data breach notification letter from Mercor dated June 2026.
- Your letter offered enrollment in free 24-month TransUnion credit monitoring and identity restoration services.
- You had personal or financial information held by Mercor, including as one of its experts or contractors.
- No proof of harm required to consult with counsel. You do not need to have already suffered identity theft to explore your legal options.

What happened
In late March 2026, LiteLLM disclosed that an unauthorized actor had inserted malware into certain versions of its widely used code scanning tool. Mercor.io Corporation ("Mercor"), a San Francisco-based artificial intelligence company, used the compromised tool. According to Mercor's notice, the malware enabled the unauthorized actor to access portions of Mercor's systems between March 24 and March 30, 2026. Mercor states that it quickly detected and blocked the activity and engaged third-party security experts to investigate the incident and strengthen its defenses.
After confirming that the threat actor had downloaded data from its systems, Mercor reviewed the affected files to identify the personal information involved. Mercor completed that review and began mailing notification letters dated June 25, 2026, and reported the incident to the California Attorney General. Mercor is offering 24 months of complimentary credit monitoring and identity restoration services through TransUnion, with an enrollment deadline of October 1, 2026. The notice confirms that personal information was downloaded but does not publicly itemize the specific data elements involved for each individual.
Because Mercor's workforce includes experts and contractors who provide identifying and payment information to the company, the categories of exposed data may include sensitive personal and financial details. Whether Mercor's pre-breach security practices and its reliance on the third-party tool met applicable standards, and whether the notification timeline caused additional harm, are among the issues being evaluated.

Common questions
I received a data breach letter from Mercor. What should I do? +
Keep the letter, enroll in the free 24-month TransUnion credit monitoring and identity restoration services before the October 1, 2026 deadline using the activation code in your notice, review your bank and credit-card statements for unfamiliar activity, place a fraud alert or credit freeze, and contact a data breach attorney for a free consultation. Accepting credit monitoring does not waive your right to sue.
Am I eligible to join a class action against Mercor? +
If you received a June 2026 breach notice from Mercor, you are likely eligible for a free case evaluation. Eligibility depends on your state of residence, the categories of your data that were exposed, and any losses you have suffered. Dapeer Law will review your notice at no cost.
How much money could I receive from a class action lawsuit? +
Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount. No payout is guaranteed, and this investigation has not yet resulted in a settlement.
What personal information was exposed in the breach? +
Mercor's notice confirms that the threat actor downloaded files containing personal information but does not publicly itemize the specific data elements for each individual. Because Mercor's experts and contractors provide identifying and payment information to the company, the exposed data may include some combination of names, contact details, and financial or tax information. Your individual notice letter should specify the categories of your data that were involved.
Did Mercor offer free credit monitoring? +
Yes. Mercor is providing 24 months of complimentary credit monitoring and identity restoration services through TransUnion, administered by Cyberscout, a TransUnion company. Enroll before the October 1, 2026 deadline using the code in your letter. Enrollment is separate from, and does not waive, your right to pursue a claim.
How many people were affected by the Mercor breach? +
The total number of affected individuals has not been publicly disclosed as of June 25, 2026. This page will be updated as additional information becomes available.
Is there a deadline to take legal action? +
Yes. Statutes of limitations for data breach claims vary by state and legal theory, typically ranging from one to six years. Waiting can permanently bar your claim. Contact us as soon as possible for a free evaluation.
How do I get a copy of the official breach notice? +
The notice was filed with the California Attorney General and is available through the California AG's public data breach portal (linked in Sources below). If you received a letter but no longer have it, Dapeer Law can assist you in obtaining a copy during your free consultation.
