  This report provides an in-depth technical analysis of the backdoor and its capabilities, and analyzes the connection between Kapeka and Sandworm group. The purpose of this report is to raise awareness amongst businesses, governments, and the broader security community. WithSecure has engaged governments and select customers with advanced copies of this report. In addition to the report, we are releasing several artifacts developed as a result of our research, including a registry-based & hardcoded configuration extractor, a script to decrypt and emulate the backdoor’s network communication, and as might be expected, a list of indicators of compromise, YARA rules, and MITRE ATT&CK mapping
