At the <\/strong>Security Analyst Summit<\/strong><\/a> in Thailand, Kaspersky\u2019s Global Research and Analysis Team (GReAT) unveiled the latest BlueNoroff APT activity through two highly targeted malicious campaigns \u2018GhostCall\u2019 and \u2018GhostHire\u2019. The ongoing operations have been targeting Web3 and cryptocurrency organizations across India, Turkiye, Australia and other countries in Europe and Asia since at least April 2025.<\/strong> <\/p>\n\n\n\n

BlueNoroff, a subdivision of the notorious Lazarus group, continues to expand its signature \u2018SnatchCrypto\u2019 campaign, a financially motivated operation which targets crypto industries worldwide. The newly described GhostCall and GhostHire campaigns employ new infiltration techniques and customized malware to compromise blockchain developers and executives. These attacks affect macOS and Windows systems as primary targets and are managed through a unified command-and-control infrastructure.<\/p>\n\n\n\n

The GhostCall campaign focuses on macOS devices, beginning with a highly sophisticated and personalized social engineering attack. The attackers reach out via Telegram, impersonating venture capitalists and in some cases using compromised accounts of real entrepreneurs and startup founders to promote investment or partnership opportunities. The victims are invited to fake investment meetings on phishing sites mimicking Zoom or Microsoft Teams during which they are prompted to \u201cupdate\u201d their client to fix an audio issue, this action downloads a malicious script and deploys a malware infection on the device.<\/p>\n\n\n\n

\u201cThis campaign relied on deliberate and carefully planned deception. Attackers replayed videos of previous victims during staged meetings to make the interaction appear like a real call and manipulate new targets. The data collected in this process is then used not only against the initial victim but also exploited to enable subsequent and supply-chain attacks, leveraging established trust relationships to compromise a broader range of organizations and users,\u201d comments Sojun Ryu, security researcher at Kaspersky GReAT.<\/p>\n\n\n\n

Attackers deployed seven multi-stage execution chains, four which were previously unseen, to distribute a range of new customized payloads, including crypto stealers, browser credential stealers, secrets stealer, and Telegram credential stealers. <\/p>\n\n\n\n

In the GhostHire campaign the APT targets blockchain developers by posing as recruiters. Victims are tricked into downloading and running a GitHub repository containing malware, presented as a skill assessment. GhostHire shares its infrastructure and tools with the GhostCall campaign, but instead of using video calls, it focuses on approaching hands-on developers and engineers through fake recruitment. After initial contact, victims are added to a Telegram bot that delivers either a ZIP file or a GitHub link, along with a short deadline to complete the task. Once executed, the malware installs itself on the victim\u2019s machine, customized for the operating system.<\/p>\n\n\n\n

The use of generative AI has enabled BlueNoroff to accelerate malware development and refine its attack techniques. The attackers introduced new programming languages and added additional features, complicating detection and analysis tasks. It further enables the actor to manage and expand its operations, increasing both the complexity and scale of attacks. <\/p>\n\n\n\n

\u201cSince its previous campaigns, the threat actor\u2019s targeting strategy has evolved beyond simple cryptocurrency and browser credential theft. The use of generative AI has significantly accelerated this process, enabling easier malware development with reduced operational overhead. This AI-driven approach helps to fill the gaps in available information, enabling more focused targeting. By combining compromised data with AI\u2019s analytical capabilities, the scope of these attacks has expanded. We hope our research will contribute to preventing further harm,\u201d comments Omar Amin, senior security researcher at Kaspersky GReAT.<\/p>\n\n\n\n
