Recent Security Issues


SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP


Title: Chinese APT using new version of PlugX malware

Description: The Chinese state-sponsored actor Bronze President (aka Mustang Panda) recently started deploying a new version of the PlugX malware in several espionage campaigns. Security researchers say the group is actively targeting the Russian military. The group is sending targets a decoy document alleged to relate to the Russian military, though it eventually downloads a malicious DLL that loads an updated version of PlugX, a remote access Trojan (RAT) previously associated with Bronze President. This group is known to previously target Asian countries with its malware, and is particularly surprising given China is military allies with Russia and has yet to strongly condemn the country’s invasion of Ukraine. Once installed, PlugX can remotely monitor and access the targeted machine.
