JunkFiction

JunkFiction is a loader associated with the financially motivated threat actor Hive0163 and with Interlock ransomware operations. IBM X-Force reporting places it in Hive0163’s broader malware toolkit alongside NodeSnake and InterlockRAT, where it is used to support long-term access and follow-on payload delivery in compromised environments. The Windows Interlock ransomware payload observed by IBM was a 64-bit PE file delivered via the JunkFiction loader, typically from temporary folders. Hive0163 is described as an extortion-focused cluster involved in large-scale data exfiltration and ransomware, with initial access commonly obtained through ClickFix social engineering, malvertising, or access brokers such as TA569/SocGholish and TAG-124/KongTuke/LandUpdate808. High-confidence content directly ties JunkFiction to delivery of Interlock ransomware, but does not provide additional standalone technical details or specific IOCs for the loader itself.
