Valéry Rieß-Marchive reports some details on the ransomware incident involving André-Mignot hospital. He suggests that someone — but not the LockBit 3.0 franchise itself — used LockBit 3.0 Black to attack the hospital and to issue a $100,000 ransom demand.
You can read his reporting and analysis on LeMagIT. From reviewing his material and additional non-public material, DataBreaches concurs with his theory that it is someone using LockBit 3.0 but not the main LockBit 3.0 or any affiliate.
