GonnaCry

GonnaCry is a publicly available ransomware/encryption tool. In the provided reporting, it is not described as a bespoke malware family with unique tradecraft; rather, it is listed among publicly available tools that DPRK state-sponsored ransomware actors have been observed using or possessing, alongside BitLocker, Deadbolt, ech0raix, Hidden Tear, Jigsaw, LockBit 2.0, My Little Ransomware, NxRansomware, Ryuk, and YourRansom. The broader campaign context in the source material concerns DPRK ransomware activity targeting U.S. and South Korean healthcare organizations and other critical infrastructure entities. That activity includes initial access via exploitation of known vulnerabilities such as CVE-2021-44228 (Log4Shell), CVE-2021-20038 (SonicWall SMA100), and CVE-2022-24990 (TerraMaster TOS), as well as distribution of Trojanized X-Popup messenger files via xpopup.pe[.]kr and xpopup[.]com. However, the content does not directly attribute those infection vectors or specific post-compromise behaviors uniquely to GonnaCry itself. No GonnaCry-specific indicators of compromise, technical behavior, ransom note details, or platform targeting are provided in the content.
