In the ever-evolving landscape of cyber threats, a new China-linked hacker group, dubbed Blackwood, has recently emerged. This sophisticated group has been quietly infiltrating systems by planting spyware in legitimate software updates since 2018. In this article, we will delve into the details of their malware, known as NSPX30, its targets, and the activities of the Blackwood APT group.
Description of the malware
The malware employed by Blackwood, named NSPX30, is a highly advanced tool deployed through mechanisms native to popular software platforms such as WPS Office, Sogou Pinyin, and Tencent QQ. Through these unsuspecting channels, the spyware skillfully targets engineering and manufacturing businesses, as well as individuals located in the UK, Japan, and China.
Background on the Blackwood APT Group
Blackwood aligns itself with China and has been actively operating since at least 2018. Their primary focus is cyber espionage, with Chinese and Japanese individuals and companies being their primary targets. Their extensive hacking campaigns have created concerns within the global cybersecurity community.
Infection Mechanism
One of the key aspects of Blackwood’s strategy is compromising machines when legitimate software attempts to download updates from trusted servers. This method allows them to slip their spyware into unsuspecting systems, targeting both personal and corporate devices. The recent surge of malicious activity in China prompted the discovery of the NSPX30 malware.
Components of NSPX30 Spyware
NSPX30 is a complex, multistage implant, involving various components that work synergistically to infiltrate and gather sensitive information. The malware consists of a dropper, an installer, loaders, an orchestrator, and a potent backdoor that grants Blackwood persistent access to compromised systems.
Victims of the spyware
Multiple victims have fallen prey to the NSPX30 spyware. This includes individuals residing in China and Japan, a Chinese-speaking individual connected to a prominent UK public research university, a large manufacturing and trading company within China, and the office of a Japanese corporation located in China. Blackwood’s extensive reach and targeting demonstrate the group’s determination and range.
Persistent and Goal-Oriented Attacks
One characteristic of Blackwood’s attacks is their persistence. If the hackers lose access to a system, they relentlessly attempt to reconnect, highlighting their targeted and goal-oriented campaigns. This dedication suggests that Blackwood is not an opportunistic group but rather one focused on achieving specific objectives.
Uncertainty Surrounding Delivery Method
Despite extensive research into Blackwood’s activities, the precise method employed to deliver malicious updates containing NSPX30 spyware remains unknown. Experts continue to investigate this critical aspect, seeking to unveil the intricacies of their distribution mechanism.
The discovery of the Blackwood hacker group and their sophisticated NSPX30 spyware underscores the evolving nature of cyber threats originating from China. Their ability to infiltrate systems through legitimate software updates poses a significant risk, particularly for engineering and manufacturing businesses across the UK, Japan, and China. Cybersecurity professionals and organizations must remain vigilant, implementing robust security measures to fend off such targeted attacks. Ongoing investigations and cooperation within the cybersecurity community are crucial in exposing and neutralizing the threat posed by groups like Blackwood.
