Jewelbug is a China-based threat actor conducting dual operations: espionage campaigns targeting foreign governments and militaries, alongside a for-profit cryptocurrency fraud business administered from the same control panel. Operating as a small development team with role-based access controls and documented roadmaps, the group recorded over one million implant check-ins, 580,000+ stolen browser cookies, and 2,300+ exfiltrated emails between February and May 2026. Espionage attacks targeted government entities in the Middle East, Southeast Asia, and South Asia with confirmed intrusions. The group deploys the Antino backdoor, a malicious Chrome/Firefox extension called 'PDF Viewer,' and a Linux implant named ClientKing targeting servers and routers. The financially motivated arm operates as a registered Hunan company running industrial-scale SEO poisoning funneling Chinese-speaking victims to fake cryptocurrency exchange sites.

A large-scale software supply chain attack compromised over 400 npm packages through a self-propagating worm called ChainDrop, a new variant of Mini Shai-Hulud. The campaign exploits stolen npm publishing credentials to automatically modify and republish legitimate software releases. ChainDrop targets developer workstations and CI/CD environments, harvesting credentials from npm, GitHub, AWS, Kubernetes, and HashiCorp Vault before validating access and enumerating resources. The malware uses preinstall lifecycle scripts for automatic execution, establishes persistence through repository configuration modifications, and abuses GitHub Actions OIDC trusted publishing workflows. After stealing credentials, it autonomously propagates by downloading packages, inserting malicious payloads, and republishing them with incremented versions, demonstrating how compromised developer identities can enable widespread ecosystem compromise.

ESET Research contributed to a global disruption operation targeting the Amadey botnet and Stealc infostealer, both malware-as-a-service offerings. The operation, coordinated by Microsoft Digital Crimes Unit, BitSight, Lumen, and MBSD, impacted approximately 50 domains and nearly 200 active IP-based command and control servers. ESET provided technical analyses, statistical information, C&C server lists, encryption keys, campaign identifiers, and affiliate-level insights gathered from three years of tracking. Both malware families operate through affiliate networks where operators deploy their own infrastructure, making disruption efforts particularly challenging. Amadey primarily functions as a modular loader distributing additional payloads, while Stealc focuses on credential theft from browsers, crypto wallets, and applications. The largest Amadey botnet cluster accounted for 34% of all samples and distributed an average of 14 payloads per victim, operating a pay-per-install model that monetized compromi...

Iran's Ministry of Intelligence has broadened its Handala brand beyond cyber operations to include physical threats and influence campaigns targeting US and Israeli interests. The expansion encompasses multiple personas: Handala Popular Resistance Front claiming physical attacks inside Israel, VIPEmployment recruiting proxies globally for espionage and sabotage, and MOISIRAN conducting surveillance operations. These entities engage in coordinated amplification across platforms, soliciting individuals to conduct attacks for financial rewards. The consolidation creates a multi-domain threat combining hacktivist activities with physical operations, espionage recruitment, and influence campaigns. This approach leverages Handala Hack Team's recognition to amplify recruitment efforts while increasing risks to law enforcement, military, intelligence personnel, and critical infrastructure across targeted regions.

Beginning in late September 2025, multiple affected hosts were observed making requests to domains impersonating content delivery networks (CDNs), including infrastructure masquerading as Yahoo- and Apple-affiliated services. Across these cases, Darktrace identified a consistent behavioral execution pattern: the retrieval of legitimate binaries alongside malicious Dynamic Link Libraries (DLLs), enabling sideloading and execution of a modular .NET-based Remote Access Trojan (RAT) framework.

In early May 2026, attackers compromised the official JDownloader website by manipulating specific installer download links through the content management system. Between May 6-7, 2026 (UTC), users who downloaded Windows installers via "Download Alternative Installer" links or the Linux shell installer were redirected to malicious third-party files instead of genuine installers. The attackers gained CMS-level access only, not server or filesystem control. The incident was detected on May 7 via Reddit alerts, and the server was immediately taken offline. Malicious links were removed, legitimate links restored, and security hardened before the site resumed normal operations on May 8-9. In-app updates and other download paths remained unaffected. Users who executed downloaded installers during the risk window are advised to perform clean OS reinstalls and change passwords from trusted devices.

Cyber threats targeting the global aviation and aerospace sector are rapidly evolving, with ransomware, identity-based intrusions, and platform-level disruptions becoming dominant attack vectors. The interconnected nature of this ecosystem, combined with time-sensitive operations and complex third-party dependencies, makes it highly attractive to threat actors. Shared airport IT platforms represent critical single points of failure, as demonstrated by the September 2025 ransomware attack on Collins Aerospace MUSE system that disrupted major European airports including Heathrow, Brussels, Berlin, and Dublin. Major ransomware groups like LockBit and Cl0p maintain heavy focus on aviation suppliers, while advanced persistent threat groups including Refined Kitten, Wicked Panda, and Fancy Bear conduct strategic espionage targeting intellectual property, aircraft design data, and military aviation intelligence. Emerging threats include vulnerabilities in regional airports, aviation SaaS platforms, and satellite ...

An emerging threat group is conducting a global SEO-poisoning campaign distributing trojanized Microsoft Teams installers that deploy a multi-stage shellcode loader and backdoor designated Lorem Ipsum. Active since February 2026, the campaign targets users searching for Microsoft Teams across six countries, with confirmed targeting of a US healthcare organization. The operators evolved rapidly from minimally obfuscated test builds to sophisticated loaders featuring substitution cipher decoding, XOR-encrypted shellcode, DLL sideloading, and JFIF-disguised C2 traffic. The malware distinctively abuses letsdiskuss[.]com, a legitimate India-based platform, as a dead-drop resolver for C2 infrastructure. Attackers use validly signed MSI installers with three-day Microsoft ID Verified certificates, NameCheap-registered infrastructure weaponized within hours, and per-victim UUID-tracked callbacks. Development velocity suggests possible LLM-assisted tooling, indicating a well-funded mid-tier criminal actor operating...

A coordinated supply chain attack targeted the axios npm package, compromising two versions (1.14.1 and 0.30.4) by injecting a malicious dependency. The attack delivered a cross-platform Remote Access Trojan to macOS, Windows, and Linux systems. The compromise occurred through the lead maintainer's npm account, bypassing normal publishing workflows. The malicious payload performed system reconnaissance, established persistence on Windows, and provided remote access capabilities. The attack affected numerous organizations and potentially exposed sensitive credentials. Immediate mitigation steps include pinning to safe versions, removing malicious dependencies, rotating credentials, and blocking the command and control server.

A supply chain poisoning attack on LiteLLM, a popular AI model gateway, was detected by NSFOCUS Technology CERT. The TeamPCP group compromised the Trivy security scanning tool used in LiteLLM's release process, allowing them to publish malicious versions 1.82.7 and 1.82.8 on PyPI. These versions contained credential-stealing programs that collected sensitive data and, if a Kubernetes cluster was detected, deployed privileged Pods and implanted persistent backdoors. The attack impacted numerous dependent packages and potentially affected millions of users. The incident highlights the growing risks in AI infrastructure and the need for robust supply chain security measures.
