npm Adds 2FA-Gated Publishing and Package Install Controls Against Supply Chain Attacks

npm Adds 2FA-Gated Publishing and Package Install Controls Against Supply Chain Attacks

5월 23, 2026 Software Supply Chain / DevSecOps
GitHub has rolled out new controls for npm to improve the security of the software supply chain, giving maintainers the ability to explicitly approve a release prior to the packages becoming publicly available for installation. Called staged publishing, the feature is now generally available on npm. It mandates that a human maintainer pass a two-factor authentication (2FA) challenge to approve a package before it is pushed to the npmjs[.]com. "Instead of a direct publish that immediately makes a package version available to consumers, the prebuilt tarball is uploaded to a stage queue where a maintainer must explicitly approve it before it becomes installable," GitHub said . The Microsoft-owned subsidiary said the change ensures "proof of presence" for every publish, including those that come from non-interactive CI/CD workflows and trusted publishing with OpenID Connect (OIDC) authentication. Before using staged publishing , package maintainers have to meet...
Packagist Supply Chain Attack Infects 8 Packages Using GitHub-Hosted Linux Malware

Packagist Supply Chain Attack Infects 8 Packages Using GitHub-Hosted Linux Malware

5월 23, 2026 Malware / DevSecOps
A new "coordinated" supply chain attack campaign has impacted eight packages on Packagist including malicious code designed to run a Linux binary retrieved from a GitHub Releases URL. "Although the affected packages were all Composer packages, the malicious code was not added to composer.json," Socket said . "Instead, it was inserted into package.json, targeting projects that ship JavaScript build tooling alongside PHP code." This "cross-ecosystem placement" makes the activity stand out because developers and security teams scanning PHP dependencies may only focus on Composer-related metadata, while skipping package.json lifecycle hooks that are bundled within the package. The malicious versions have since been removed from Packagist. An analysis of the packages has uncovered that their upstream repositories have been modified to include a postinstall script that attempts to download a Linux binary from a GitHub Releases URL ("github[...

Megalodon GitHub Attack Targets 5,561 Repos with Malicious CI/CD Workflows

5월 22, 2026 Supply Chain Attack / Cloud Security
Cybersecurity researchers have disclosed details of a new automated campaign called Megalodon that has pushed 5,718 malicious commits to 5,561 GitHub repositories within a six-hour window. "Using throwaway accounts and forged author identities (build-bot, auto-ci, ci-bot, pipeline-bot), the attacker injected GitHub Actions workflows containing base64-encoded bash payloads that exfiltrate CI secrets, cloud credentials, SSH keys, OIDC tokens, and source code secrets to a C2 server at 216.126.225[.]129:8443," SafeDep said in a report. The complete list of data harvested by the malware is below - CI environment variables, /proc/*/environ, and PID 1 environment Amazon Web Services (AWS) credentials Google Cloud access tokens Instance role credentials obtained by querying AWS IMDSv2, Google Cloud metadata, and Microsoft Azure Instance Metadata Service (IMDS) endpoints SSH private keys Docker and Kubernetes configurations Vault tokens Terraform crede...

GitHub Internal Repositories Breached via Malicious Nx Console VS Code Extension

GitHub Internal Repositories Breached via Malicious Nx Console VS Code Extension

5월 21, 2026 Supply Chain Attack / Developer Tools
GitHub on Wednesday officially confirmed that the breach of its internal repositories was the result of a compromise of an employee device involving a poisoned version of the Nx Console Microsoft Visual Studio Code (VS Code) extension.  The development comes as the Nx team revealed that the extension, nrwl.angular-console , was breached after one of its developers' systems was hacked in the wake of the recent TanStack supply chain attack. Other companies that were impacted by the TanStack compromise include OpenAI, Mistral AI , and Grafana Labs . "We have no evidence of impact to customer information stored outside of GitHub's internal repositories, such as our customer's own enterprises, organizations, and repositories," Alexis Wales, Chief Information Security Officer of GitHub, said in a statement. "Some of GitHub's internal repositories contain information from customers, for example, excerpts of support interactions. If any impact is discov...
GitHub Breached — Employee Device Hack Led to Exfiltration of 3,800+ Internal Repos

GitHub Breached — Employee Device Hack Led to Exfiltration of 3,800+ Internal Repos

5월 20, 2026 Malware / Cloud Security
GitHub on Tuesday said it's investigating unauthorized access to its internal repositories after the notorious threat actor known as TeamPCP listed the platform's source code and internal organizations for sale on a cybercrime forum. "While we currently have no evidence of impact to customer information stored outside of GitHub's internal repositories (such as our customers' enterprises, organizations, and repositories), we are closely monitoring our infrastructure for follow-on activity," the Microsoft-owned subsidiary said . The company also noted that it will notify customers via established incident response and notification channels if any impact is discovered. The development comes after TeamPCP, a threat actor behind a string of software supply chain attacks targeting open-source packages, listed GitHub's source code for sale for an asking price of no less than $50,000. The alleged data dump is said to include about 4,000 repositories. ...
Grafana GitHub Breach Exposes Source Code via TanStack npm Attack

Grafana GitHub Breach Exposes Source Code via TanStack npm Attack

5월 20, 2026 Supply Chain Attack / Cloud Security
Grafana Labs, on May 19, 2026, said an investigation into its recent breach found no evidence of customer production systems or operations being compromised. It said the scope of the incident is limited to the Grafana Labs GitHub environment, which includes public and private source code along with internal GitHub repositories. "After the initial assessment, we found that in addition to source code, the downloaded content included GitHub repositories that some Grafana Labs teams use to collaborate on and store internal operational information and other details about our business," it said . "This includes business contact names and email addresses that would be exchanged in a professional relationship context, not information pulled from or processed through the use of production systems or the Grafana Cloud platform." The open-source visualization software maker also noted that the breach originated from the TanStack npm supply chain attack orchestrated ...
Compromised Nx Console 18.95.0 Targeted VS Code Developers with Credential Stealer

Compromised Nx Console 18.95.0 Targeted VS Code Developers with Credential Stealer

5월 19, 2026 Supply Chain Attack / Developer Security
Cybersecurity researchers have flagged a compromised version of the Nx Console extension that was published to the Microsoft Visual Studio Code (VS Code) Marketplace. The extension in question is rwl.angular-console (version 18.95.0), a popular user interface and plugin for code editors like VS Code, Cursor, and JetBrains. The VS Code extension has more than 2.2 million installations. The Open VSX version has not been affected by the incident. "Within seconds of a developer opening any workspace, the compromised extension silently fetched and executed a 498 KB obfuscated payload from a dangling orphan commit hidden inside the official nrwl/nx GitHub repository," StepSecurity researcher Ashish Kurmi said . The payload is a "multi-stage credential stealer and supply chain poisoning tool" that harvests developer secrets and exfiltrates them via HTTPS, the GitHub API, and DNS tunneling. It also installs a Python backdoor on macOS systems that abuses the GitHub S...
Developer Workstations Are Now Part of the Software Supply Chain

Developer Workstations Are Now Part of the Software Supply Chain

5월 18, 2026 Artificial Intelligence / Developer Security
Supply chain attackers are not only trying to slip malicious code into trusted software. They are trying to steal the access that makes trusted software possible. Recently, three separate campaigns hit npm, PyPI, and Docker Hub in a 48-hour window, and all three targeted secrets from developer environments and CI/CD pipelines, including API keys, cloud credentials, SSH keys, and tokens. This is an ongoing concern and is self-propagating, as seen in attacks like the "mini Shai Hulud" campaigns.  That pattern should change how security teams think about the software supply chain. Traditionally, security focused on shared systems like source code repositories, CI/CD platforms, artifact registries, package managers, and cloud environments. The goal was to protect production workloads and data. We absolutely still need to focus on these areas, but it is an incomplete picture.  Modern software delivery begins before code reaches Git. It begins on the developer workstation, wher...
Four Malicious npm Packages Deliver Infostealers and Phantom Bot DDoS Malware

Four Malicious npm Packages Deliver Infostealers and Phantom Bot DDoS Malware

5월 18, 2026 Supply Chain Attack / Botnet
Cybersecurity researchers have discovered four new npm packages containing information-stealing malware, one of which is a clone of the Shai-Hulud worm open-sourced by TeamPCP . The list of identified packages is below - chalk-tempalte (825 Downloads) @deadcode09284814/axios-util (284 Downloads) axois-utils (963 Downloads) color-style-utils (934 Downloads) "One of the packages (chalk-tempalte) contains a direct clone of the Shai-Hulud source code that TeamPCP leaked last week, probably inspired as part of the supply chain attack competition that was published in BreachForums not long after," OX Security's Moshe Siman Tov Bustan said. Interestingly, the malicious payloads embedded into the four npm packages are different, despite them being published by the same npm user, " deadcode09284814 ." As of writing, the four libraries are still available for download from npm. An analysis of the packages has revealed that "axois-utils" is designed ...
Grafana GitHub Token Breach Led to Codebase Download and Extortion Attempt

Grafana GitHub Token Breach Led to Codebase Download and Extortion Attempt

5월 17, 2026 Data Breach / Cybercrime
Grafana has disclosed that an "unauthorized party" obtained a token that granted them the ability to access the company's GitHub environment and download its codebase. "Our investigation has determined that no customer data or personal information was accessed during this incident, and we have found no evidence of impact to customer systems or operations," Grafana said in a series of posts on X. The company also said it immediately launched a forensic analysis upon discovering the activity and that it identified the source of the leak, adding the compromised credentials have since been invalidated, and extra security measures have been implemented to secure against unauthorized access. Furthermore, Grafana revealed the attacker tried to blackmail and extort the company, demanding they make a payment to prevent the stolen database from being published. Grafana said it has opted not to pay the ransom, citing guidance issued by the U.S. Feder...

5월 11, 2026 Supply Chain Attack / DevSecOps
Checkmarx has confirmed that a modified version of the Jenkins AST plugin was published to the Jenkins Marketplace. "If you are using Checkmarx Jenkins AST plugin, you need to ensure that you are using the version 2.0.13-829.vc72453fa_1c16 that was published on December 17, 2025 or previously," the cybersecurity company said in a statement over the weekend. As of writing, Checkmarx has released 2.0.13-848.v76e89de8a_053 on both GitHub and the Jenkins Marketplace. A spokesperson for the company said the new version addresses the concerns associated with the incident. It's assessed that the malicious code was published after obtaining credentials from a previous supply chain attack that took place in March 2026. The development is the latest attack orchestrated by TeamPCP targeting Checkmarx. It arrives a couple of weeks after the notorious cybercrime group was attributed to the compromise of its KICS Docker image, two VS Code extensions, and a GitHub Actions workflo...

Poisoned Ruby Gems and Go Modules Exploit CI Pipelines for Credential Theft

5월 01, 2026 Supply Chain Attack / Malware
A new software supply chain attack campaign has been observed using sleeper packages as a conduit to subsequently push malicious payloads that enabled credential theft, GitHub Actions tampering, and SSH persistence. The activity has been attributed to the GitHub account " BufferZoneCorp ," which has published a set of repositories that are associated with malicious Ruby gems and Go modules. As of writing, the packages have been yanked from RubyGems, and the Go modules have been blocked. The names of the libraries are listed below - Ruby: knot-activesupport-logger knot-devise-jwt-helper knot-rack-session-store knot-rails-assets-pipeline knot-rspec-formatter-json knot-date-utils-rb (Sleeper gem) knot-simple-formatter (Sleeper gem) Go: github[.]com/BufferZoneCorp/go-metrics-sdk github[.]com/BufferZoneCorp/go-weather-sdk github[.]com/BufferZoneCorp/go-retryablehttp github[.]com/BufferZoneCorp/go-stdlib-ext github[.]com/BufferZoneCorp/grpc-client github[.]com...

Google Fixes CVSS 10 Gemini CLI CI RCE and Cursor Flaws Enable Code Execution

Google Fixes CVSS 10 Gemini CLI CI RCE and Cursor Flaws Enable Code Execution

4월 30, 2026 AI Security / Vulnerability
Google has addressed a maximum severity security flaw in Gemini CLI -- the "@google/gemini-cli" npm package and the "google-github-actions/run-gemini-cli" GitHub Actions workflow -- that could have allowed attackers to execute arbitrary commands on host systems. "The vulnerability allowed an unprivileged external attacker to force their own malicious content to load as Gemini configuration," Novee Security said in a Wednesday report. "This triggered command execution directly on the host system, bypassing security before the agent’s sandbox even initialized." The shortcoming, which does not have a CVE identifier, carries a CVSS score of 10.0. It affects the following versions - @google/gemini-cli < 0.39.1 @google/gemini-cli < 0.40.0-preview.3 google-github-actions/run-gemini-cli < 0.1.22 In its advisory published last week, Google said the impact is limited to workflows using Gemini CLI in headless mode, adding that any use of...

Cybersecurity researchers are sounding the alarm about a new supply chain attack campaign targeting SAP-related npm Packages with credential-stealing malware. According to reports from Aikido Security , Onapsis , OX Security ,  SafeDep , Socket , StepSecurity , and Google-owned Wiz , the campaign – calling itself the Mini  Shai-Hulud – has affected the following packages associated with SAP's JavaScript and cloud application development ecosystem - mbt@1.2.48 @cap-js/db-service@2.10.1 @cap-js/postgres@2.2.2 @cap-js/sqlite@2.2.2 "The affected versions introduced new installation-time behavior that was not previously part of these packages' expected functionality," Socket said. "The compromised releases added a preinstall script that acts as a runtime bootstrapper, downloading a platform-specific Bun ZIP from GitHub Releases, extracting it, and immediately executing the extracted Bun binary." "The implementation also follows HTTP redirects wi...
LiteLLM CVE-2026-42208 SQL Injection Exploited within 36 Hours of Disclosure

LiteLLM CVE-2026-42208 SQL Injection Exploited within 36 Hours of Disclosure

4월 29, 2026 Vulnerability / Cloud Security
In yet another instance of threat actors quickly jumping on the exploitation bandwagon, a newly disclosed critical security flaw in BerriAI's LiteLLM Python package has come under active exploitation in the wild within 36 hours of the bug becoming public knowledge. The vulnerability, tracked as CVE-2026-42208 (CVSS score: 9.3), is an SQL injection that could be exploited to modify the underlying LiteLLM proxy database. "A database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter," LiteLLM maintainers said in an alert last week. "An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route (for example, POST /chat/completions) and reach this query through the proxy's error-handling path. An attacker could read data from the proxy's database and may be able to modify it, leading to unauthorized access to the proxy and the c...
Researchers Discover Critical GitHub CVE-2026-3854 RCE Flaw Exploitable via Single Git Push

Researchers Discover Critical GitHub CVE-2026-3854 RCE Flaw Exploitable via Single Git Push

4월 28, 2026 Vulnerability / Software Security
Cybersecurity researchers have disclosed details of a critical security vulnerability impacting GitHub.com and GitHub Enterprise Server that could allow an authenticated user to obtain remote code execution with a single "git push" command. The flaw, tracked as CVE-2026-3854 (CVSS score: 8.7), is a case of command injection that could allow an attacker with push access to a repository to achieve remote code execution on the instance. "During a git push operation, user-supplied push option values were not properly sanitized before being included in internal service headers," per a GitHub advisory for the vulnerability. "Because the internal header format used a delimiter character that could also appear in user input, an attacker could inject additional metadata fields through crafted push option values." Google-owned cloud security firm Wiz has been credited with discovering and reporting the issue on March 4, 2026, with GitHub validating and deployi...
Brazilian LofyGang Resurfaces After Three Years With Minecraft LofyStealer Campaign

Brazilian LofyGang Resurfaces After Three Years With Minecraft LofyStealer Campaign

4월 28, 2026 Malware / Supply Chain Attack
A cybercrime group of Brazilian origin has resurfaced after more than three years to orchestrate a campaign that targets Minecraft players with a new stealer called LofyStealer (aka GrabBot). "The malware disguises itself as a Minecraft hack called 'Slinky,'" Brazil-based cybersecurity company ZenoX said in a technical report. "It uses the official game icon to induce voluntary execution, exploiting the trust of young users in the gaming scene." The activity has been attributed with high confidence to a threat actor known as LofyGang , which was observed leveraging typosquatted packages on the npm registry to push stealer malware in 2022, specifically with an intent to siphon credit card data and user accounts associated with Discord Nitro, gaming, and streaming services. The group, believed to be active since late 2021, advertises their tools and services on platforms like GitHub and YouTube, while also contributing to an underground hacking communit...

"If we determine that customer information was involved in this incident, we will notify...
Tropic Trooper Uses Trojanized SumatraPDF and GitHub to Deploy AdaptixC2

Tropic Trooper Uses Trojanized SumatraPDF and GitHub to Deploy AdaptixC2

4월 24, 2026 Malware / Threat Intelligence
Chinese-speaking individuals are the target of a new campaign that uses a trojanized version of SumatraPDF reader to deploy the AdaptixC2 Beacon post-exploitation agent and ultimately facilitate the abuse of Microsoft Visual Studio Code (VS Code) tunnels for remote access. Zscaler ThreatLabz, which discovered the campaign last month, has attributed it with high confidence to Tropic Trooper (aka APT23, Earth Centaur, KeyBoy, and Pirate Panda), a hacking group known for its targeting of various entities in Taiwan, Hong Kong, and the Philippines. It's assessed to be active since at least 2011. "The threat actors created a custom AdaptixC2 Beacon listener, leveraging GitHub as their command-and-control (C2) platform," security researcher Yin Hong Chang said in an analysis. It's believed that Chinese-speaking individuals in Taiwan, and individuals in South Korea and Japan, are the targets of the campaign. The starting point of the attack is a ZIP archive containing...
