WilmerHale Data Breach Lawsuit Investigation Closed
Our WilmerHale data breach investigation is now closed.
A proposed class action arising out of the May 2026 data security incident at Wilmer Cutler Pickering Hale and Dorr LLP (WilmerHale) has already been filed in court by another law firm. Because the matter is now in litigation, Dapeer Law, P.A. has closed this investigation and is not accepting new WilmerHale inquiries.
Why this investigation is closed
On July 14, 2026, a proposed class action captioned Perry v. Wilmer Cutler Pickering Hale and Dorr LLP, No. 1:26-cv-02470, was filed in the U.S. District Court for the District of Columbia arising out of the May 2026 data security incident. The case was brought by another law firm. Dapeer Law, P.A. is not counsel of record in that action.
When a case covering the same incident and substantially the same proposed class is already in litigation, filing a duplicate lawsuit rarely benefits consumers. For that reason, we have closed our WilmerHale investigation and are not accepting new inquiries for this matter.

What this means for you
If you received a breach notification letter from WilmerHale, here is where things stand:
- You do not need to do anything with Dapeer Law for this matter. Our investigation is closed.
- You may fall within the class described in the filed complaint. Proposed class members generally do not need to hire their own lawyer to remain part of a class while litigation is pending.
- If a class is certified or a settlement is reached, a court-approved notice is typically sent to affected individuals explaining their rights and how to submit a claim.
- Keep your breach notice letter. It is often useful documentation if a claims process opens later.
What you can still do
Keep your notice letter
Do not discard it. Your letter documents that your information was involved, which is typically needed if a settlement claims process opens.
Use the protections offered
Enroll in any free credit monitoring offered in your letter before the stated deadline, and consider a fraud alert or credit freeze with Equifax, Experian, and TransUnion. Accepting these benefits does not waive your legal rights.
Watch for court-approved notices
If the filed case settles or a class is certified, affected individuals are typically notified by mail or email with instructions on how to participate.

Common questions
Why did Dapeer Law close its WilmerHale investigation? +
A proposed class action covering the May 2026 data security incident, Perry v. Wilmer Cutler Pickering Hale and Dorr LLP, No. 1:26-cv-02470, was filed in the U.S. District Court for the District of Columbia on July 14, 2026 by another law firm. Because the matter is already in litigation, we closed our investigation and are not accepting new WilmerHale inquiries.
Can I still be part of the WilmerHale class action? +
If you received a breach notice from WilmerHale, you may fall within the class described in the filed complaint. Proposed class members generally do not need to sign up or hire their own lawyer while litigation is pending. If a settlement is approved or a class is certified, a court-approved notice typically explains who is included and how to submit a claim.
I already submitted my information to Dapeer Law. What happens now? +
Thank you. Submissions received while our investigation was open have been reviewed, and no further action is needed from you for this matter. If anything about your submission requires follow-up, we will contact you directly.
Will I receive money from the WilmerHale lawsuit? +
No recovery is guaranteed. The case is at the complaint stage, WilmerHale disputes the allegations, and there is no settlement or claims process at this time. If a settlement is reached and approved by the court, affected individuals typically receive a notice explaining how to file a claim. Keep your breach notice letter in the meantime.
Does the closure change what I should do about the breach itself? +
No. The practical steps stay the same: keep your notice letter, enroll in any free credit monitoring offered, consider a fraud alert or credit freeze with the three major credit bureaus, and monitor your accounts and tax filings for signs of fraud.
