Microsoft Threat Intelligence discovered a large-scale npm supply chain attack compromising 32 malicious packages across over 90 versions under the @redhat-cloud-services scope. The compromise originated from the RedHatInsights/javascript-clients CI/CD pipeline, enabling attackers to publish trojanized packages through legitimate GitHub Actions OIDC workflows with authentic provenance signatures. The malicious packages executed a heavily obfuscated 4.29 MB dropper via npm preinstall hooks, which downloaded the Bun JavaScript runtime and launched payloads designed to harvest credentials from GitHub, npm, AWS, Azure, GCP, HashiCorp Vault, Kubernetes, and developer systems. The malware scraped GitHub Actions runner memory for secrets, escalated privileges using passwordless sudo, exfiltrated stolen data through GitHub infrastructure, and propagated by compromising additional maintainer packages with forged SLSA provenance. The campaign marker "Miasma: The Spreading Blight" was embedded throughout the malicious
A supply chain attack compromised multiple @redhat-cloud-services npm packages, executing malicious payloads automatically during installation via preinstall hooks. The attack uses AES-GCM encrypted payloads and obfuscated JavaScript loaders to harvest GitHub Actions secrets, npm tokens, cloud credentials (AWS, Azure, GCP), Kubernetes and Vault material, SSH keys, Git credentials, and cryptocurrency wallet files. The payload can daemonize on developer workstations, includes Russian-locale avoidance mechanisms, and exfiltrates stolen data through encrypted HTTPS channels with GitHub API fallback mechanisms. The campaign employs tactics similar to the publicly released Shai-Hulud toolkit, though attribution remains unclear due to the availability of open-source attack tooling.
JINX-0164, a financially motivated threat actor active since mid-2025, has been conducting sophisticated campaigns against cryptocurrency organizations. The actor employs LinkedIn-based social engineering, posing as recruiters or business partners to deliver custom macOS malware including AUDIOFIX (a Python-based infostealer and RAT) and MINIRAT (a lightweight Go backdoor). Their operations focus on compromising developer endpoints to steal cryptocurrency wallet credentials, cloud secrets, and GitHub tokens. The attackers then pivot to CI/CD infrastructure, injecting malicious code into repositories to enable lateral movement. In April 2026, they executed a supply chain attack by trojanizing the npm package @velora-dex/sdk. The group masks activity using VPN services and demonstrates advanced capabilities including credential harvesting from password managers, browser extensions, and development tools.
Community-maintained Laravel Lang packages were compromised with remote code execution backdoors affecting over 700 versions across multiple repositories including laravel-lang/lang, laravel-lang/http-statuses, laravel-lang/attributes, and laravel-lang/actions. The attack involved coordinated rapid tag publishing on May 22-23, 2026, suggesting organization-level credential compromise. A malicious helpers.php file was automatically executed via Composer's autoloader, deploying a sophisticated cross-platform information stealer. The second-stage payload systematically harvested credentials from cloud infrastructure, Kubernetes, CI/CD systems, browsers, password managers, cryptocurrency wallets, VPN clients, and local configurations. Stolen data was encrypted and exfiltrated to a command-and-control server. The backdoor employed advanced evasion techniques including TLS verification bypass, per-host execution markers, and embedded Windows executables to bypass Chrome encryption protections.
The Mini Shai-Hulud campaign compromised 84 npm package artifacts in the TanStack namespace with credential-stealing malware targeting continuous integration systems.

A supply chain attack has compromised the node-ipc npm package, with malicious versions 9.1.6, 9.2.3, and 12.0.1 containing obfuscated stealer and backdoor functionality. The attack vector involved takeover of a dormant maintainer account through an expired email domain. The malware fingerprints host environments, enumerates and reads local files including SSH keys, cloud credentials, database configurations, and various developer secrets. Collected data is compressed into a gzip archive and exfiltrated via DNS TXT queries to attacker-controlled infrastructure disguised as legitimate Azure domains. The payload targets over 100 file patterns across macOS and Linux systems, focusing on developer credentials from AWS, Azure, GCP, Kubernetes, Docker, npm, GitHub, and numerous other services. The malicious code executes during CommonJS module loading, forking a detached child process to perform credential harvesting while avoiding detection through obfuscation and DNS-based covert channels.
A sophisticated npm supply chain attack was uncovered involving the typosquatted package crypto-javascri, designed to mimic the legitimate crypto-js library. The malware harvests npm and GitHub credentials from infected systems, hijacks maintainer accounts, and automatically republishes trojanized versions of packages under trusted identities. The final payload incorporates a weaponized Arti Tor client with credential theft, cryptomining capabilities, privilege escalation via SUID exploitation, and systemd-based persistence mechanisms. The campaign specifically targets Linux developer systems and CI/CD environments, using Tor-based command-and-control infrastructure to maintain anonymity and resilience. The attack creates significant downstream supply chain risk through its worm-like propagation model.
A long-running typosquatting campaign impersonated the widely used shopspring/decimal Go library by publishing github.com/shopsprint/decimal, differing by a single character. Active since November 2017, the package remained benign through seven releases until being weaponized in August 2023 with version v1.3.3. This version introduced a malicious init() function that executes automatically on import, establishing a DNS TXT record-based command and control channel to dnslog-cdn-images.freemyip.com. The backdoor polls every five minutes and executes arbitrary commands returned via TXT records. Although the GitHub repository and owner account have been deleted, the malicious module remains permanently cached and accessible through Go's module proxy system, continuing to pose a supply chain risk to developers who mistype the package name.
A supply chain attack targeting the Microsoft DurableTask Python client compromised versions 1.4.1, 1.4.2, and 1.4.3 on PyPi.

Stolen data is encrypted with AES-256-GCM and exfiltrated to a command-and-control server, with GitHub repositories used as fallback channels. The malware contains worm-like functionality to republish compromised packages and propagate through the npm ecosystem.
A supply chain compromise involving Daemon Tools installers distributed via the official vendor website has been identified. The attackers used valid code-signing certificates to make the trojanized installers appear legitimate and bypass security controls. These malicious packages deploy a backdoor that performs system reconnaissance, environment verification, and communicates with attacker-controlled command-and-control infrastructure. The compromise leverages trusted software delivery mechanisms to evade detection, establish persistent access, and enable remote command execution. Organizations should block related malicious infrastructure, hunt for suspicious Daemon Tools installations and network activity, verify software integrity, and implement application allowlisting. Monitoring for unusual certificate usage in software deployment is also advised. No patch or official fix information is available, and no known exploits in the wild have been reported.
Five malicious NuGet packages published under account bmrxntfj impersonate Chinese .NET libraries to deploy an infostealer targeting browser credentials, cryptocurrency wallets, SSH keys, and local files. The packages typosquat legitimate Chinese UI and infrastructure libraries, grafting .NET Reactor-protected payloads onto decompiled legitimate code. The campaign uses version rotation to evade hash-based detection, with 219 of 224 total versions unlisted but fetchable. The stealer targets 12 browsers, 8 desktop crypto wallets, and 5 browser wallet extensions, exfiltrating data to a newly-registered C2 domain. With approximately 65,000 downloads across all versions, the campaign puts tens of thousands of developer workstations and CI/CD build servers at risk. The payload executes through .NET module initializers, hooks the CLR JIT compiler, and supports cross-platform infection including Linux and macOS infrastructure.
Between July 2025 and present, threat actors suspected to be OceanLotus distributed malicious wheel packages through PyPI targeting both Windows and Linux platforms. Three fake libraries (uuid32-utils, colorinal, and termncolor) were created to imitate legitimate packages, implementing a sophisticated supply chain attack. The packages deployed droppers that delivered ZiChatBot, a previously unknown malware family using Zulip's REST APIs as command and control infrastructure instead of traditional C2 servers. The malware supports executing shellcode commands and establishes persistence through registry keys on Windows or crontab on Linux. Attribution to OceanLotus is based on 64% similarity with known droppers analyzed by KTAE system. The malicious packages were swiftly removed from PyPI following discovery.
A malicious artifact of the widely-used intercom/intercom-php package version 5.0.2 was discovered on Packagist, representing an expansion of the Mini Shai-Hulud supply chain attack from npm into the PHP ecosystem. The compromised package exploits Composer plugin execution to download Bun runtime and execute an obfuscated credential-stealing payload during installation. The malicious code harvests sensitive credentials including GitHub tokens, cloud provider credentials, SSH keys, Kubernetes tokens, and HashiCorp Vault secrets from developer machines and CI/CD environments. Stolen data is encrypted using AES-256-GCM and exfiltrated to attacker-controlled infrastructure.
