Important Security Notice Regarding the Canvas Platform
Instructure, the vendor for Canvas, recently experienced a security incident involving unauthorized activity that resulted in data exfiltration. San Juan School District (SJSD) was notified that its data was impacted.
Data Believed to Be Compromised
Based on the investigation, potentially impacted data includes:
Names
Email addresses
Student identification numbers
Messages exchanged within the Canvas platform
Instructure found no evidence that passwords, dates of birth, government identifiers (such as Social Security numbers), or financial information were involved.
Recommendations
Because the potentially compromised data includes names and email addresses, we urge all affected individuals to be extremely vigilant against targeted phishing attacks, as this type of information is frequently leveraged for that purpose.
Next Steps and Notifications
Canvas has stated that they will individually contact users whose specific data is found to have been exfiltrated once their data review is complete.
