🔒Drift Protocol lost at least $280 million after an attacker seized administrative control of its Security Council and drained protocol funds. Blockchain intelligence firms Elliptic and TRM Labs linked the operation to North Korean actors, citing on-chain tradecraft such as Tornado Cash use, CarbonVote timing, cross-chain bridging, and rapid laundering. Drift says no smart contract bugs or seed phrases were compromised; core functions are frozen while investigations continue.

🔒 FortiGuard Labs identified a multi-stage campaign using malicious LNK shortcut files that target Microsoft Windows users in South Korea. The attacker embeds decoding routines inside LNK arguments to drop a decoy PDF while executing hidden PowerShell payloads. Those scripts perform anti-analysis checks, establish persistence via Scheduled Tasks and VBScript, and use GitHub API calls as a covert C2 and exfiltration channel. Fortinet signatures detect these components and block the activity.

🛡️ Google's Threat Intelligence Group has attributed a supply chain compromise of the popular Axios npm package to a suspected North Korean cluster tracked as UNC1069. Attackers seized a maintainer npm account and pushed trojanized releases (1.14.1 and 0.30.4) that added a malicious dependency, plain-crypto-js. That dependency used a postinstall hook to deploy an obfuscated dropper (SILKBELL) which fetched OS-specific payloads and ultimately installed the WAVESHAPER.V2 backdoor. Organizations should audit dependency trees, search node_modules for plain-crypto-js, isolate affected hosts, block the C2 domain sfrclak[.]com, and rotate credentials.

🚫 The UK’s Foreign, Commonwealth and Development Office has sanctioned Xinbi, a Chinese-language marketplace accused of selling stolen personal data and satellite internet equipment to Southeast Asian scam networks and assisting North Korean actors with cryptocurrency laundering. Chainalysis links Xinbi to over $19.9 billion in transactions from 2021–2025. The measures also target #8 Park and operator Legend Innovation Co, aiming to sever Xinbi from legitimate crypto services and disrupt payments to scam centers.

🛡️ The North Korean-linked group Contagious Interview (aka WaterPlum) is abusing Visual Studio Code auto-run tasks to distribute a Node.js-based malware family called StoatWaffle. Malicious projects use tasks.json with runOn: folderOpen to automatically fetch and install Node.js, then execute a downloader that chains to next-stage modules. StoatWaffle includes a browser credential stealer and a RAT capable of file operations, command execution, and data exfiltration.

🔎 Behavioral analytics and threat intelligence combined to identify a suspected North Korea-linked fake IT worker within 10 days of hire. LevelBlue SpiderLabs and Cybereason XDR flagged geolocation anomalies, unmanaged device access, and use of Astrill VPN, triggering a high-severity alert and timely account revocation. Organizations should enforce EntraID Conditional Access, manage endpoints, and maintain software baselines to detect such insider threats.

🚨 The U.S. Department of the Treasury's Office of Foreign Assets Control has sanctioned six individuals and two entities tied to a DPRK-run IT worker scheme that secured remote jobs, stole data, and funneled salaries back to North Korea to finance weapons programs. The operation—tracked as Coral Sleet/Jasper Sleet (also called PurpleDelta/Wagemole)—used stolen identities, fabricated personas, VPN services, and AI-enabled tools to conceal origins, launder funds, and deploy malware or extort victims. OFAC named Amnokgang Technology Development Company and several facilitators, currency converters, and account enablers; security firms and Microsoft warn the campaign leverages Astrill VPN, AI faceswaps, agentic LLM misuse, and offshore operations to maintain persistent, low-cost access.

🔍 GitLab research outlines a North Korean campaign that impersonated recruiters in the 'Contagious Interview' scheme and resulted in the banning of 131 attributed accounts. Many GitLab projects served as obfuscated loaders for malware such as BeaverTail and Ottercookie, with payloads hosted outside repositories. Operators used consumer VPNs, VPSs and laptop farms and shifted to invite-only projects, NPM dependency abuse, sandbox detection and AI-generated personas to scale fake IT worker and freelance scams.

🔒 Google links the North Korean actor UNC4899 to a 2025 cloud compromise that leveraged personal-to-corporate file transfers (AirDrop) and malicious code embedded in a shared archive. Attackers pivoted from a compromised developer device into Google Cloud, abused CI/CD and Kubernetes workflows, and manipulated Cloud SQL to extract funds. The campaign employed living-off-the-cloud techniques and persisted by injecting commands into deployment configurations. Recommended mitigations include phishing-resistant MFA, strict secrets management, and restricting P2P file sharing on corporate endpoints.

🔍 Researchers disclosed a new StegaBin iteration of the Contagious Interview campaign in which North Korean actors uploaded 26 malicious packages to the npm registry. The packages masqueraded as developer tools and used text steganography in Pastebin essays to encode Vercel-based C2 addresses, ultimately delivering a credential stealer and a cross-platform RAT. Install-time scripts fetch multi-stage components that enable persistence, credential harvesting, and exfiltration.

🛡️ Zscaler researchers uncovered a toolkit named Ruby Jumper used by North Korea–linked APT37 to bridge internet-connected and air-gapped systems via removable drives. The campaign begins with a malicious LNK that launches a PowerShell script, a decoy document, and the RESTLEAF implant, which fetches encrypted shellcode via Zoho WorkDrive and loads the Ruby-based loader SNAKEDROPPER. The threat persists by installing a Ruby runtime masked as usbspeed.exe and weaponizes USB media to relay commands and exfiltrate data.

🔒 In December 2025, Zscaler ThreatLabz exposed the Ruby Jumper campaign linking North Korea's ScarCruft to a novel multi-stage intrusion that abuses cloud storage and removable media. The attack begins with a malicious LNK that launches PowerShell to extract an embedded decoy document and multiple payloads, including the in-memory loader RESTLEAF. RESTLEAF uniquely leverages Zoho WorkDrive for C2 to fetch shellcode and stage follow-on components, while SNAKEDROPPER, THUMBSBD, and VIRUSTASK enable persistence, surveillance, and propagation to air-gapped systems via USB.

⚠️ Researchers report a new phishing campaign in which North Korean hackers pose as company recruiters and lure developer job candidates with seemingly legitimate coding challenges. When victims run the supplied code, it installs malware on their machines, creating a direct avenue for compromise. Reversing Labs analyzed the samples and BleepingComputer provided additional reporting. Candidates and employers should be cautious about running unvetted code and verify recruiter identities.

🔒A Ukrainian man was sentenced to five years in prison after admitting he helped North Korean IT workers infiltrate US companies using stolen identities. He pleaded guilty in November 2025 to aggravated identity theft and conspiracy to commit fraud and agreed to forfeit over $1.4 million in cash and cryptocurrency. Authorities say he sold hundreds of stolen identities and provided proxy accounts and laptop farms to disguise foreign workers as US-based.

🔒 Broadcom's Symantec and Carbon Black Threat Hunter Team reports the North Korea-linked Lazarus Group used Medusa ransomware in an attack against an unnamed Middle East entity and mounted an unsuccessful attempt against a U.S. healthcare organization. Medusa is a RaaS launched by Spearwing in 2023 and has been tied to hundreds of incidents. Analysts say this reflects a tactical shift toward off-the-shelf ransomware and affiliate operations, with the campaign leveraging tools such as RP_Proxy, Mimikatz, Comebacker, InfoHook, BLINDINGCAN, and ChromeStealer.

🔒 Symantec says a North Korean Lazarus subgroup is using Medusa ransomware to extort U.S. healthcare organizations, marking the first public linkage between Lazarus and Medusa. The attacks combine commodity utilities with custom tools — Comebacker, Blindingcan, ChromeStealer, Infohook, Mimikatz and RP_Proxy — and have hit multiple healthcare and non-profit victims. Symantec published IoCs and warns demands can reach $15 million.

🛡️ A 29-year-old Ukrainian national was sentenced to five years in U.S. prison after pleading guilty to charges tied to a scheme that sold stolen U.S. identities to overseas IT workers, enabling them to secure jobs at roughly 40 American companies and funnel wages back to North Korea. Prosecutors say he operated Upworksell.com, managed hundreds of proxy identities and U.S.-based laptop farms, and was ordered to pay $46,547.28, serve 12 months of supervised release, and forfeit more than $1.4 million.

⚖️ Oleksandr Didenko, a 39-year-old Ukrainian, was sentenced to 60 months in prison and 12 months of supervised release after pleading guilty to aggravated identity theft and wire fraud conspiracy for selling stolen U.S. identities to foreign IT workers. Using the seized platform UpWorkSell, he provided at least 871 proxy identities and accounts that helped applicants secure positions with roughly 40 U.S. companies and supported multiple "laptop farms" that masked device locations. Authorities also seized more than $1.4 million in cash and cryptocurrency tied to the scheme.

⚠️ A new variant of a fake recruiter campaign attributed to North Korean actors is targeting JavaScript and Python developers with cryptocurrency-themed coding tasks. Attackers publish seemingly legitimate job projects and embed malicious dependencies on npm and PyPI that install a remote access trojan reported as Graphalgo. The operation is modular and resilient, with 192 malicious packages identified and tactics such as delayed activation and token‑protected command channels. Affected developers are advised to rotate tokens and passwords and to reinstall compromised systems.

⚠️ Google’s Threat Intelligence Group (GTIG) says the North Korea-linked actor UNC2970 and other state-aligned groups abused Gemini for target profiling, reconnaissance, and campaign planning. GTIG found use cases ranging from synthesizing OSINT and crafting tailored phishing personas to automating vulnerability analysis and debugging exploit code. Researchers identified malware such as HONESTCUE, which queries Gemini’s API to generate C# stage-two loaders compiled in memory, and an AI-built phishing kit called COINBAIT. Google also reported and mitigated large-scale model extraction activity aimed at replicating Gemini’s behavior.
