	"plain_text": "IRONHALO (Malware Family)\r\nBy Fraunhofer FKIE\r\nArchived: 2026-04-05 23:06:34 UTC\r\nIRONHALO is a downloader that uses the HTTP protocol to retrieve a Base64 encoded payload from a hard-coded command-and-control (CnC) server and uniform resource locator (URL) path.\r\nThe encoded payload is written to a temporary file, decoded and executed in a hidden window. The encoded and\r\ndecoded payloads are written to files named igfxHK[%rand%].dat and igfxHK[%rand%].exe respectively, where\r\n[%rand%] is a 4-byte hexadecimal number based on the current timestamp. It persists by copying itself to the\r\ncurrent user’s Startup folder.\r\n[TLP:WHITE] win_ironhalo_auto (20251219 | Detects win.ironhalo.)\r\nSource: https://malpedia.caad.fkie.fraunhofer.de/details/win.ironhalo\r\nhttps://malpedia.caad.fkie.fraunhofer.de/details/win.ironhalo\r\nPage 1 of 1",
