FBI: Beware of Full Network Ransomware

The FBI issued an alert describing an aggressive ransomware campaign (Samas/Kazy/RDN) that exploits vulnerable JBoss applications to propagate across networks, encrypt files using RSA-2048 and attempt to manually delete backups; the bulletin distributes indicators and advises standard protections such as up-to-date antivirus, regular patching, segregated backups and least-privilege access.
