Iaffaldano, Shaw & Young LLP Listed by revil Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Iaffaldano, Shaw & Young LLP Listed by revil Ransomware Group (reported September 9, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
Breaking down the breach
On September 09, 2021, Iaffaldano, Shaw & Young LLP was listed on the leak site operated by the revil ransomware group. The group stated that it had obtained internal files during a ransomware operation. No further details on the timing of the intrusion, the volume of data, or the method of access have been made public. The number of individuals whose information may be involved is also undisclosed.
The group behind it: revil
REvil, also tracked as Sodinokibi, operated a ransomware-as-a-service model in which affiliates deployed the malware and the core group handled infrastructure and leak-site operations. The group routinely used double-extortion tactics: encrypting systems and then threatening to publish stolen files if a ransom was not paid. It had previously listed other professional-services and legal entities on its site. In this case the group claims to hold data from Iaffaldano, Shaw & Young LLP, but that claim has not been independently verified.
Iaffaldano, Shaw & Young LLP and its sector
Iaffaldano, Shaw & Young LLP is a law firm. Legal practices routinely store client records, correspondence, contracts, and supporting documentation that can contain personal identifiers, financial details, and privileged communications. A listing on a ransomware leak site raises the possibility that such material could be published, though the firm has not confirmed the extent or nature of any exfiltration.
The information in question
The only description provided is that internal files were taken. Specific categories of data have not been released by either the firm or the group. Organisations of this type commonly hold names, addresses, identification numbers, financial account references, and case-related documents, but it is not confirmed whether any of these elements are present in the material referenced in the listing.
Why it matters
Publication of law-firm files can expose individuals to identity misuse, unwanted disclosure of private legal matters, or follow-on fraud attempts. For the organisation, the incident adds operational costs for investigation, client notification, and potential regulatory review. Because the scale and contents remain unknown, the practical impact on any single person cannot yet be quantified.
What to do if you're exposed
People who have been clients or counterparties of the firm can take several practical steps while awaiting further information from the organisation.
- Review recent account statements and credit reports for unfamiliar activity.
- Enable multi-factor authentication on any accounts that may be linked to information held by the firm.
- Consider placing a credit freeze or fraud alert if financial identifiers appear to be at risk.
- Contact the firm directly to ask what, if any, data concerning you was involved.
- Run a free exposure scan of your email address against known breach data sets to check for additional appearances.

Publicly posted by revil — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
