Cornerstone Staffing Solutions, a major US recruitment agency, has reportedly suffered a ransomware attack by the Qilin group, leading to the theft of over 120,000 resumes and more than 1 million company files. The Qilin gang, known for using double extortion tactics, claims to have pulled 300 GB of sensitive data from Cornerstone’s systems. Among the stolen information are personal details including Social Security numbers, addresses, and phone numbers, although it’s unclear if this data pertains to job seekers or Cornerstone employees. The Qilin group has gained notoriety for its aggressive tactics and recently teamed up with other cybercriminal organizations. Their recent attacks have targeted various sectors, including manufacturing and healthcare, highlighting the risks associated with companies holding sensitive information. Cornerstone has not yet responded to inquiries regarding the breach. The implications of this leak are serious, as the exposed resumes could facilitate phishing attacks and identity theft, while the internal documents may compromise Cornerstone's operational integrity.
