The Shai Hulud supply chain worm, attributed to TeamPCP, compromises CI/CD pipelines by injecting malicious npm/PyPI packages that harvest build credentials and pivot into production AWS cloud infrastructure. In a confirmed breach, attackers stole Jenkins EC2 instance role credentials via the Instance Metadata Service (IMDS), used them from external IPs, escalated privileges by creating an IAM user with AdministratorAccess, modified Redshift and Aurora security groups to open network paths, enumerated Secrets Manager for warehouse credentials, and exfiltrated data via the Redshift Data API. The attack demonstrates that pipeline identity equals production identity, with explicit attacker naming conventions (exfil-s3-* policies, exfil STS session names) providing high-fidelity detection opportunities.

A new wave of the Mini Shai-Hulud/Miasma/Hades supply chain attack campaign has compromised 23 npm packages across the LeoPlatform and RStreams ecosystems, plus the Verana Blockchain Go module. The attack uses binding.gyp install-time execution (Phantom Gyp pattern) to trigger multi-stage obfuscated JavaScript loaders that decrypt AES-GCM payloads, stage execution through Bun to evade Node.js security hooks, and steal developer/CI/CD credentials including npm, GitHub, cloud, and AI-agent tokens. The campaign also poisons GitHub Actions workflows and plants persistence hooks in AI coding assistant configurations, creating delayed execution surfaces that survive package remediation.

The Miasma Mini Shai-Hulud supply chain campaign has expanded to compromise 22 npm package versions under the @immobiliarelabs scope, targeting Backstage plugins for GitLab integration and LDAP authentication. The malicious packages use a binding.gyp 'Phantom Gyp' trick to execute hidden root-level index.js payloads without preinstall/postinstall hooks, followed by AES-128-GCM decryption and multi-stage delivery under the Bun runtime. The final payload exfiltrates developer and CI/CD secrets via the GitHub API to attacker-controlled repositories, and the campaign likely propagated through a compromised codfish/semantic-release-action GitHub Action that enabled access to release automation credentials.

This threat intelligence report highlights multiple critical vulnerabilities and active exploits, including a zero-day in Oracle PeopleSoft (CVE-2026-35273) exploited by ShinyHunters and an IKEv1 authentication bypass in Check Point VPNs (CVE-2026-50751) linked to Qilin ransomware. Additionally, the report details emerging AI-driven threats, a supply-chain compromise in the Arch User Repository deploying eBPF rootkits, and widespread patching efforts by Microsoft and Veeam.

Perimeter Auth Collapse and AI-Driven Deception Shift the Battlefield The security perimeter cracked open this week as critical authentication bypasses in Check Point VPNs, Ivanti Sentry, and Palo Alto GlobalProtect gave attackers a free pass into corporate networks, with Qilin ransomware already exploiting one to launch real attacks. At the same time, AI became the year's most versatile weapon: criminals used ChatGPT and Claude brands as phishing lures, researchers proved AI email assistants will hand over corporate secrets to impersonators, and the Shai-Hulud campaign began injecting fake prompts to blind AI-powered security scanners. Patch edge VPN appliances immediately, treat AI agents as high-risk insiders, and hunt for device-code authentication events that bypass normal credential checks.

2026-06-047 minSocketcritical

A supply chain attack dubbed 'Mini Shai-Hulud' compromised numerous npm packages, notably within the @redhat-cloud-services namespace. The malicious packages use preinstall hooks to execute an obfuscated loader that decrypts and runs a credential-harvesting payload via the Bun runtime, targeting CI/CD secrets, cloud credentials, and developer tokens for encrypted exfiltration.

Session Hijacking and Developer Tool Poisoning Collapse Authentication Trust This week, attackers proved that multi-factor authentication is no longer a reliable gatekeeper. Campaigns like Tycoon 2FA and Chinese-language PhaaS platforms intercept one-time passwords in real time and steal session tokens to maintain persistent access, while infostealers like EKZ Infostealer harvest browser cookies to bypass authentication entirely. Even when victims reset passwords and revoke sessions, attackers retain access through hidden device registrations — meaning standard incident response playbooks are now incomplete. Developers remain the preferred entry point for supply chain compromise. The Glassworm botnet was disrupted after hiding malware in VSCode extensions and npm packages, while the Megalodon campaign poisoned GitHub Actions workflows across 5,500 repositories. A malicious Sicoob.Sdk NuGet package stole banking certificates from Brazilian developers, and North Korea's Lazarus group compromised the widely used axios npm library — a single attack touching millions of downstream applications. Organizations must move beyond password-and-MFA reliance: adopt hardware security keys, shorten session lifetimes, delete attacker-registered devices before resetting credentials, and audit developer toolchains and CI/CD pipelines for tampering.

A supply chain attack dubbed 'megalodon' compromises GitHub Action YAML configurations by injecting base64-encoded malicious scripts to exfiltrate repository data. Analysis of the C2 infrastructure, identified as the NEXUS Listener framework, links this activity to a prior campaign that exploited CVE-2026-41940 in cPanel servers to deploy cryptominers and steal high-value cloud credentials.

Developer Supply Chains Under Siege as Edge Device Exploits Surge The dominant narrative this week is the coordinated weaponization of the software supply chain, as threat actors like TeamPCP and Mini Shai-Hulud aggressively target developer tools to steal cloud credentials. Because these attackers compromise trusted build systems like GitHub Actions, a single malicious package—such as the compromised TanStack libraries—can cascade into massive downstream breaches, allowing criminals to hold development environments hostage and even deploy destructive dead-man switches if their access is cut off. In parallel, attackers are bypassing traditional network defenses by exploiting internet-facing edge devices and logging in with stolen credentials. Threat clusters are actively exploiting critical flaws in Cisco Catalyst SD-WAN and Microsoft Exchange, while ransomware groups like The Gentlemen and state-sponsored actors like Secret Blizzard use these footholds to live off the land, hijacking legitimate IT tools to stay hidden for months. These trends together suggest that perimeter-focused defenses and basic patching are no longer sufficient. Organizations must immediately isolate their CI/CD pipelines from cloud credentials, enforce phishing-resistant multi-factor authentication on all internet-facing systems, and assume that trusted vendor tools may already be compromised.
