Ransomware Group Claims It Targeted Traverse City Schools. Traverse City Area Public Schools: The Medusa ransomware group claimed a cyberattack against the Traverse City public schools, resulting in the cancellation of classes in early April, after allegedly stealing 1.2 TB of data and demanding a total of $1 million to not disclose the data and decrypt it. The school district administration, in collaboration with a third-party cybersecurity company, the police, and the FBI, is investigating the incident without reporting any identity theft or fraud related to this attack so far. Medusa is known for its double extortion technique and has already targeted other school districts, exploiting vulnerabilities to maximize payments. Linked ransomware group: Medusa.
