Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Shadowbyt3$ on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Post text · scraped from the leak site

Stride Learning Should've Paid the ransom. We were only asking $500,000 in bitcoin or monero it's not that hard. This is a warning to all companies that if you don't pay it will get leaked. If you pay you have are word that it's deleted also with a picture before and after. If you want we will also take a video.
