CrazyHunter Ransomware
CrazyHunter is a ransomware campaign targeting healthcare that weakens endpoint defenses and escalates privileges before encrypting systems at scale.
PYSA OVERVIEW
The Pysa Ransomware is a popular Ransomware-as-a-Service (RaaS) that has been observed operating since at least mid-2019. The name "Pysa" is possibly derived from the Zanzibari coin of the same name. The actors have also claimed the name to be an acronym for "Protect Your System Amigo."
ACTORS
It should be noted that the actors that use the Pysa RaaS also frequently engage in doxware operations where they exfiltrate data pre-encryption and threaten to disclose it on their leak site should the ransom not be paid.
