Zeppelin is a Delphi-based ransomware family derived from Vega and operated as a ransomware-as-a-service offering from 2019 through at least mid-2022. It has targeted businesses and critical-infrastructure organizations, notably healthcare and medical entities, as well as defense contractors, educational institutions, manufacturers, and technology companies. Operators have obtained access through exploitation of exposed RDP services, exploitation of SonicWall firewall vulnerabilities, and phishing including spearphishing. Intrusions commonly involved one to two weeks of network reconnaissance, identification of data stores and backups, and theft of sensitive data before encryption, enabling double-extortion pressure. Zeppelin can be deployed as a DLL, executable, or through a PowerShell loader; it encrypts files, appends randomized hexadecimal extensions, and leaves ransom instructions. Multiple executions within a victim environment can produce separate victim identifiers and require separate decryption keys. Zeppelin has been deployed by affiliates and third-party ransomware operators, including Vice Society, rather than being exclusive to a single threat actor.

1 CVE Mallory has correlated with this family across public research and vendor advisories. Each row links to the full Mallory page for that vulnerability.
Exploiting publicly available vulnerabilities (such as PrintNightmare) to perform remote code execution seems to be the most advanced technique the group has been observed using. | Sekoia investigations show they are currently leveraging the Zeppelin ransomware targeting Windows systems... The Zeppelin samples masquerade as legitimate Windows processes and seem to be linked to the PrintNightmare vulnerability exploitation.
