Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
1 distinct threat actor attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
The recent discovery of attack activities involves the utilization of undisclosed Trojan programs (Trojan 1, named WalkerShell due to its inclusion of the specific string “walker”...)
7 distinct techniques documented for this family, organized by ATT&CK tactic.
When executed, it first utilizes the polor function to obtain the hostname and username of the target host...
Subsequently, they downloaded ORPCBackdoor and other malicious payloads, conducted disk directory traversal, and exfiltrated target files to C2... On another compromised machine, the attacker implants the WalkerShell trojan, which traverses the disk and uploads files of interest to a dedicated file storage server.
Upon analysis, it was found that the attackers downloaded a total of three different malicious payloads, including ORPCBackdoor, a Trojan specifically designed to steal Chrome browser password records (named DemoTrySpy), and a backdoor program for downloading and executing shellcode (named NixBackdoor).
Subsequently, they downloaded ORPCBackdoor and other malicious payloads, conducted disk directory traversal, and exfiltrated target files to C2. Additionally, the organization stole password information from the target computer browsers and transmitted it back.
1 indicator attributed across vendor reports, sandbox runs, and researcher write-ups. Full values are available in Mallory.

"...The group's arsenal also includes ORPCBackdoor, walkershell, MSMQSPY and LastopenSpy..."
A C# trojan used as an initial intrusion tool. It collects host and user information, receives commands from the server, traverses disks, and uploads files of interest. It is also used to help transmit stolen browser credential data.
