Wicked Panda (also known as Winnti Group, Axiom, BARIUM, and Shadowpad) was extremely active in the Month of October with two new pieces of malware making their debuts: Portreuse and Skip 2.0. It is uncommon to see two new pieces of malware debut in the same month from the same threat actor. However, Wicked Panda is only a part of a much larger umbrella organization. For instance, Crowdstrike mentioned in a July 26th blog post that "WICKED PANDA refers to the targeted intrusion operations of the actor publicly known as “Winnti,” whereas WICKED SPIDER represents this group’s financially-motivated criminal activity. The flexibility of the cryptonym system used by CrowdStrike to track adversaries is highlighted by the case of WICKED PANDA/SPIDER. In this instance, one set of activities associated with criminal motivations can be easily separated from a second set of behaviors by the same actor when operating in the interest of a nation-state." As for the new tools, Portreuse is a backdoor that is injected into a running process so that it can reuse this already open port to wait for commands from a C2 server. This is also known as a passive network implant and early indications are that the group is targeting mobile hardware and software manufacturers. Skip 2.0 is also a backdoor. It targets Microsoft SQL (MSSQL) servers through the use of a "magic password" that allows the threat actors to connect to any account of the server and hide.Related Reading
