Recommended actions
- Treat any unsolicited message referencing Instructure Holdings, Inc. (Canva LMS, instructure.com) as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on instructure.com, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Education organisations should review this group's known TTPs and validate detection coverage against them.
