U.S. and South Korean cyber agencies warned Monday about a ransomware-as-a-service outfit, Gunra, that reportedly recruits ethical hackers and penetration testers and benefits from North Korean government-linked hackers’ tools to target government and critical infrastructure organizations.

Gunra has gone after sectors such as academia, financial services and insurance, government services and facilities, healthcare, manufacturing and construction, media, retail, transportation and utilities. Its global scope is far-ranging, according to Monday’s alert: Africa, the Americas, the Asia-Pacific, Europe and the Middle East.

“Gunra is another variant in the ongoing trend of ransomware attacks causing disruption and harm to U.S. and international organizations,” said Chris Butera, acting assistant director for cybersecurity at the Cybersecurity and Infrastructure Security Agency, which produced the advisory with the Department of Defense’s Cyber Crime Center, FBI, National Security Agency, Secret Service and Republic of Korea’s National Police Agency.

The alert is part of the #StopRansomware series, a joint FBI-CISA project aimed at network defenders.

The FBI first took notice of Gunra in April of last year. The double-extortion group established a data leak site on Tor to list victims and publish purloined data. By January of this year, Gunra had launched a formal ransomware-as-a-service affiliate and was growing in its ambition, Monday’s alert states.

“The FBI observed the group adopting new branding aliases (notably operating under the name Golden Community) to support this expansion,” it reads. “Gunra has further commercialized its platform by actively recruiting penetration testers and ethical hackers to serve as initial access brokers, offering a share of the ransom profits in exchange for enterprise network access.”

Gunra seeks initial access with known vulnerabilities in internet-facing devices like firewalls or virtual private networks, and is based on or influenced by the Conti ransomware code leaked in 2022, according to the agencies.

Research published in July by a South Korean cybersecurity firm took note of Gunra overlap with Lazarus Group, although it doesn’t explicitly mention the latter group’s name.

“These commonalities suggest that although the state-sponsored threat group and the Gunra ransomware group appear to be separate threat actors with different ultimate objectives, they may have shared certain techniques, tools, and infrastructure or collaborated to a limited extent during the attacks,” AhnLab wrote in its report.

That kind of North Korean government-ransomware gang collaboration dates back to at least 2024. Nor is Gunra alone among ransomware-as-a-service outfits recruiting penetration testers.

The Paris Peace Forum, a French non-profit that has convened world leaders on global security issues, is launching a new project to bring together international experts to assess AI-related threats to global internet infrastructure.

The Integrated Network for Trusted AI in Cyberspace (INTAiC) will tap researchers and civil society experts from government and the private sector, analyzing current AI cyber threats from the field and creating “forward-looking” reports on how the technology will impact society and what organizations can do to respond.

One of the project’s top goals is to create an international, quick-response coalition of government and business to address AI-related threats, similar to coordination mechanisms that exist in other areas of cybersecurity.

“Evidence fragmentation on AI-driven cyber threats isn’t incidental — it’s structural: those defending networks and those securing AI systems have long worked in separate spheres,” said Adrien Abecassis, policy initiatives director for the Paris Peace Forum. “That’s exactly why INTAiC is unique — it’s built to turn those fragments into one comparable reading of the threat, because this is a challenge no actor can meet alone.”

The network already lists a number of prominent businesses and organizations, including Microsoft, the Cyber Threat Alliance, the Cloud Security Alliance, Orange Cyberdefense and others.

According to the forum, INTAiC’s work will focus primarily on two, separate workstreams. One is a single and regularly updated resource for defenders to stay up to date on how AI is reshaping cyber threats. The resource is focused more on attacker capabilities, different forms of misuse and the impact on security operations rather than isolated incidents.

“The result is a common reference point, grounded in reality, that gives policymakers a clearer measure of the threat and identifies the risks most deserving of collective attention,” the Forum said in a release.

The second workstream will focus on evaluating and preventing cyber risks associated with AI, building up a base of independent third-party experts who can provide neutral or unbiased assessments of frontier model cyber capabilities. That work will pull in governments, research institutions and non-profits to develop new organizational and funding pathways to support that kind of research.

While the U.S. federal government has come a long way in recent years building up its own capacity to test and study AI cyber threats, much of the access and technical expertise around frontier model capabilities are concentrated within commercial AI companies. This has at times created concerns that federal agencies were being overly reliant on AI companies to explain how the technology worked and walk them through the possible threat scenarios.

As Anthropic and OpenAI have rolled out defensive cybersecurity programs like Project Glasswing and the Trusted Access for Cyber program, access to those models have become available to a wider group of researchers and organizations.

The Paris Peace Forum intends to brief the public further on INTAiC’s work and accomplishments in Paris later this year during the organization’s annual conference in November.
