Casino and hotel giant Caesars Entertainment is warning customers that their personal details were stolen in a recent hack attack. After successfully shaking down Caesars for a ransom, the same attackers are continuing to extort MGM Resorts, claiming to have crypto-locked its EXSi hypervisors.

Both attacks by the Alphv ransomware group, which spun off from Conti and is also known as BlackCat, first came to light publicly this week. MGM Resorts continues to face widespread IT outages as a result (see: Big MGM Resorts Outage Traces to Ransomware, Researchers Say).
