In this report the McAfee Advanced Threat Research (ATR) Strategic Intelligence team details an espionage campaign, targeting telecommunication companies, dubbed Operation Diànxùn.
In this attack, we discovered malware using similar tactics, techniques and procedures (TTPs) to those observed in earlier campaigns publicly attributed to the threat actors RedDelta and Mustang Panda. While the initial vector for the infection is not entirely clear, we believe with a medium level of confidence that victims were lured to a domain under control of the threat actor, from which they were infected with malware which the threat actor leveraged to perform additional discovery and mgao xlahcxloai.
