A shadowy nation-state group known as TGR-STA-1030 has been identified as the perpetrator of a wide-ranging espionage campaign against governments and critical infrastructure organizations across the globe. Researchers at Unit 42 have characterized their activities as "alarming" and "potential long-term consequences for national security and key services." The group's sophisticated tactics and nation-state backing make them a significant concern for cybersecurity professionals and policymakers alike.
TGR-STA-1030 is a highly secretive and skilled cyber operative nation-state group identified by Palo Alto Networks.The group has conducted a wide-ranging espionage campaign against governments and critical infrastructure organizations globally, focusing on ministries of finance, economy, defense, foreign affairs, and commerce.TGR-STA-1030 uses phishing emails, known vulnerabilities in Microsoft Exchange, SAP, and Atlassian products to gain initial access to victim organizations.The group has been linked to a new Linux kernel rootkit called ShadowGuard, which evades detection by security filters and hides process information at the kernel level.TGR-STA-1030 has conducted "active reconnaissance" against 155 governments across multiple continents between November and December 2025.The group's activities have been linked to real-world geopolitical events, such as scanning Czech infrastructure after Czech President Petr Pavel met with the Dalai Lama in August 2025.
In recent months, a sophisticated and highly secretive nation-state group has been making headlines in the cybersecurity community. Identified as TGR-STA-1030 by Palo Alto Networks, this group of skilled cyber operatives has been conducting a wide-ranging espionage campaign against governments and critical infrastructure organizations across the globe.
According to researchers at Unit 42, a prominent cybersecurity firm, TGR-STA-1030's activities have been marked by a concerted focus on ministries of finance, economy, defense, foreign affairs, and commerce. The group's tactics have included the use of phishing emails, known vulnerabilities in Microsoft Exchange, SAP, and Atlassian products to gain initial access to victim organizations.
One notable example of TGR-STA-1030's activities was observed in February 2025, when Unit 42 spotted a series of phishing campaigns targeting European governments. The lures used in these campaigns were related to ministry or department reorganization, with links to malicious files hosted on mega.nz. In one instance, an Estonian government entity even took the step of uploading a ZIP archive containing the malware to VirusTotal's malware repository.
The archive, which bore the filename "Changes to the organizational structure of the Police and Border Guard Board," contained a malware loader named DiaoYu.exe. This malware was notable for its ability to evade detection by security filters, as it only checked for five antivirus products: Kaspersky, Avira, Bitdefender, SentinelOne, and Symantec.
TGR-STA-1030's activities have also been linked to a new Linux kernel rootkit called ShadowGuard, which is believed to be unique to this particular nation-state group. This stealthy Extended Berkeley Packet Filter (eBPF) backdoor hides process information, directories, and files at the kernel level, making it extremely difficult to detect.
The group's activities have not been limited to Europe, however. Researchers have also observed TGR-STA-1030 conducting "active reconnaissance" against 155 governments across the Americas, Europe, Asia, and Africa between November and December 2025. This included scanning government infrastructure across North, Central, and South America, as well as targeting Czech and Venezuelan government-owned IP addresses.
In one notable instance, researchers observed TGR-STA-1030 conducting "extensive reconnaissance activities" against at least 140 government-owned IP addresses in Venezuela shortly after January 3, when an American military operation captured Venezuelan President Nicolás Maduro and his wife.
The group's activities have also been linked to real-world geopolitical events. For example, researchers observed TGR-STA-1030 scanning Czech infrastructure across the army, police, parliament, and ministries of interior, finance, and foreign affairs in August 2025, shortly after Czech President Petr Pavel privately met with the Dalai Lama during a trip to India.
In light of these activities, researchers at Unit 42 have cautioned that TGR-STA-1030 remains an active threat to government and critical infrastructure worldwide. The group's sophisticated tactics and nation-state backing make them a significant concern for cybersecurity professionals and policymakers alike.
