On Sept. 10, 2025, the Qilin ransomware group claimed responsibility for a cyberattack targeting Spectra Logic Corporation, a leading provider of data storage and management solutions. According to a dark web posting, Qilin stated they had successfully infiltrated Spectra Logic’s systems and obtained sensitive organizational data. The breach was later disclosed to the Massachusetts Office of Consumer Affairs and Business Regulation on Dec. 3, 2025.
The attack was classified as a ransomware incident, meaning the perpetrators not only accessed but also likely encrypted or exfiltrated sensitive data. The Qilin group is known for targeting organizations and threatening to leak or sell stolen data unless a ransom is paid. The severity of this breach is notable due to the type of information compromised and the public claim by a sophisticated ransomware group on the Tor network.
Based on the Massachusetts data breach report, the breach affected at least 18 individuals in Massachusetts so far. However, the investigation is ongoing and the number of impacted individuals is subject to change. The exposed information may have included Social Security numbers, names, dates of birth, addresses, driver's license information, and financial account information.
The exposure of personally identifiable information (PII) puts individuals at risk of identity theft and financial fraud.
