China-linked adversaries have been attributed to an ongoing onslaught against Indian power grid organizations, one year after a concerted campaign targeting critical infrastructure in the country came to light.
Most of the intrusions involved a modular backdoor named ShadowPad, according to Recorded Future’s Insikt Group, a sophisticated remote access trojan that has been dubbed a “masterpiece of privately sold malware in Chinese espionage.”
“ShadowPad continues to be employed by an ever-increasing number of People’s Liberation Army (PLA) and Ministry of State Security (MSS)-linked groups, with its origins linked to known MSS contractors first using the tool in their own operations and later likely acting as a digital quartermaster,” the researchers said.
The goal of the sustained campaign, the cybersecurity company said, is to facilitate intelligence gathering pertaining to critical infrastructure systems in preparation for future contingency operations. The targeting is believed to have commenced in September 2021.
The attacks took aim at seven State Load Despatch Centres (SDLCs) located primarily in Northern India, in particular those close to the disputed India-China border in Ladakh, with one of the targets victimized in a similar attack disclosed in February 2021 and attributed to the RedEcho group.
The 2021 RedEcho attacks involved the compromise of 10 distinct Indian power sector organizations, including six of the country’s regional and state load despatch centers (RLDC), two ports, a nation power plant, and a substation.
Recorded Future linked the latest set of malicious activities to an emerging threat cluster it’s tracking under the moniker Threat Activity Group 38 aka TAG-38 (similar to the UNC#### and DEV-#### designations given by Mandiant and Microsoft), citing “notable distinctions” from that of the previously identified RedEcho TTPs.
In addition to attacking power grid assets, TAG-38 impacted a national emergency response system and the Indian subsidiary of a multinational logistics company.
Although the initial infection vector used to breach the networks is unknown, the ShadowPad malware on the host systems was commandeered by means of a network of infected internet-facing DVR/IP camera devices geolocated in Taiwan and South Korea. Read more:https://bit.ly/3rcUzkI
