Student-submitted personal info via linked Google Form: name, email address, home address, date of birth, grade level, and bank name","Westport Public Schools reported that a district staff email account (identified as a Spanish teachers account) was hijacked on a Friday afternoon and then used to send a phishing email to students in grades K12 with the subject line Employment Program For Westport Public Schools.

Because the email originated from an internal staff account, it bypassed normal email restrictions and reached student inboxes across the district, including Staples High School. District officials said the technology department removed all copies of the email from the school system and began identifying students who clicked the link and may have submitted personal information; families of students who filled out the form were contacted directly and advised to monitor accounts for fraud.

Antilliaans Dagblad reported that Scholengemeenschap Bonaire (SGB) was hit by an international ransomware attack, discovered internally after multiple servers failed to start.

SGB said regular education operations were not impacted because key systems ran in a secured cloud environment (including student/admin platforms and Microsoft Office), and it stated usernames/passwords were not stolen. The school reported filing a police report and notifying the BES data protection oversight body, and required staff and students to change passwords and remain vigilant for phishing.
