An ongoing data extortion attack targeting the widely-used education technology platform Canvas disrupted classes and coursework at school districts and universities across the United States today, after a cybercrime group defaced the service's login page with a ransom demand that threatened to leak data from 275 million students and faculty across nearly 9,000 educational institutions.

U.S. prosecutors last week levied criminal hacking charges against 19-year-old U.K. national Thalha Jubair for allegedly being a core member of Scattered Spider, a prolific cybercrime group blamed for extorting at least $115 million in ransom payments from victims. The charges came as Jubair and an alleged co-conspirator appeared in a London court to face accusations of hacking into and extorting several large U.K. retailers, the London transit system, and healthcare providers in the United States.

There are indications that U.S. healthcare giant Change Healthcare has made a $22 million extortion payment to the infamous BlackCat ransomware group (a.k.a. "ALPHV") as the company struggles to bring services back online amid a cyberattack that has disrupted prescription drug services nationwide for weeks. However, the cybercriminal who claims to have given BlackCat access to Change's network says the crime gang cheated them out of their share of the ransom, and that they still have the sensitive data that Change reportedly paid the group to destroy. Meanwhile, the affiliate's disclosure appears to have prompted BlackCat to cease operations entirely. 

The ransomware group LockBit told officials with Fulton County, Ga. they could expect to see their internal documents published online this morning unless the county paid a ransom demand. Instead, LockBit removed Fulton County's listing from its victim shaming website this morning, claiming county officials had paid. But county officials said they did not pay, nor did anyone make payment on their behalf. Security experts say LockBit was likely bluffing and probably lost most of the data when the gang's servers were seized this month by U.S. and U.K. law enforcement.
