Mainetti USA Inc. has reported a ransomware attack by the Qilin group that may have exposed sensitive personal and financial information. Impacted individuals are being notified and offered 18 months of free credit monitoring.
Mainetti USA’s Data Breach Investigation
Mainetti USA Inc., a global supplier of packaging and branding solutions, recently confirmed a significant data security event. On June 12, 2025, the Qilin ransomware group reportedly gained unauthorized access to portions of Mainetti USA’s computer systems. The attackers attempted to encrypt company files and disrupted some systems, including a printer server, which was encrypted on June 18. In response, the company quickly shifted to backup systems to maintain business operations.
Although the company’s cybersecurity team and third-party forensic experts found no evidence that personal data was exfiltrated, Qilin posted screenshots of internal documents, such as statements of work and invoices, to its leak site. This prompted Mainetti USA to conduct a comprehensive review to identify potentially compromised information.
That review concluded on September 4, 2025, and revealed that some files may have contained sensitive personal details. The exposed data potentially includes names, addresses, Social Security numbers, driver’s license numbers, digital signatures, medical details, and financial account information (without access codes).
Mainetti USA has since notified law enforcement, including the FBI, and is enhancing its security protocols. Although the company has not confirmed any misuse of personal data, it is offering 18 months of complimentary credit monitoring services through Aura to those affected. This measure reflects the company’s stated commitment to data privacy and consumer protection.
If you were notified of this incident, you may have grounds for legal action. Even without proof of data misuse, the exposure of such sensitive details could carry long-term risks.
