Grimaldi Alliance Data Listed by Black Basta
On November 27, 2024, the international law firm Grimaldi Alliance appeared on the leak site operated by the Black Basta ransomware group. The listing claims that roughly 1.5 TB of the firm’s internal files were exfiltrated during a ransomware incident. The primary disclosure, hosted on the Black Basta onion site and mirrored on ransomware.live, states that attackers obtained corporate data, financial records, accounting files, payroll information, HR documents, employee personal data, client personal data, and other confidential materials.

What the Leak Site Discloses
The Black Basta listing explicitly names grimaldialliance.com and provides the Milan headquarters address along with the firm’s main telephone number. It categorizes the stolen material into four groups: corporate and financial data including accounting and payroll; HR records and employee personal documents; client personal data and documents; and additional confidential files. The disclosure does not specify the exact number of individuals affected, nor does it list individual record counts for employees or clients. It simply asserts that the data was taken during a ransomware attack and is now available for download by authorized purchasers on the extortion platform.
Internal files exfiltrated is the consistent description used across the leak page. No sample files are openly published in the initial listing, which is typical for Black Basta’s staged extortion model.
Why This Matters for You and Your Family
When a global law firm suffers a breach of this scale, the exposure reaches far beyond the company’s walls. If you or any member of your family has ever been a client of Grimaldi Alliance, worked there, or had personal or financial dealings documented in their systems, your information may now sit inside a 1.5-terabyte archive controlled by criminals. Payroll records, HR files, and client documents frequently contain full names, addresses, dates of birth, tax identifiers, banking details, and scanned copies of passports or contracts. Once that material leaves legitimate control, it can surface in identity-theft operations for years.
