QBOT Malware Analysis

Elastic Security Labs presents a detailed reverse-engineering analysis of the QBOT (Qakbot) V4 banking trojan from a recent campaign, documenting its three-stage execution (initialization, installation, communication), process injection and multi-user installation techniques, dynamic persistence, C2 protocol (encrypted JSON over HTTP/TLS), public-key message verification, string/resource/import obfuscation, and a list of extracted network infrastructure and command handlers; the report also provides YARA rules, a configuration extractor, and investigative artifacts (IOCs).
