Cybersecurity researchers have discovered a malicious NuGet package that masquerades as a C# software development kit for Sicoob, one of Brazil's largest cooperative financial systems, to siphon client IDs and PFX certificates. According to Socket , versions 2.0.0 through 2.0.4 of " Sicoob.Sdk " contain functionality to exfiltrate sensitive information, including PFX certificates that are used to authenticate businesses with the Sicoob banking network in order to automate banking operations, such as processing instant payments and generating dynamic Pix QR codes. The package is estimated to have been downloaded nearly 500 times. "When a developer instantiates SicoobClient with a client ID, a PFX file path, and a PFX password, the package reads the PFX file from disk, Base64-encodes its contents, and sends the supplied client ID, PFX password, and encoded PFX data to a hardcoded third-party Sentry endpoint," security researcher Kirill Boychenko said. In ad...

A new campaign orchestrated by a previously undocumented threat actor has targeted cryptocurrency organizations with an aim to facilitate digital asset theft using recruitment-themed social engineering and bespoke macOS malware. "These campaigns leveraged sophisticated social engineering techniques, custom macOS malware, and deep targeting of CI/CD infrastructure," Wiz researchers Shira Ayal, Eden Abergil, Andre Maccarone, Yuval Dan, and Benjamin Read said . "The used methods enabled the threat actor to move laterally from compromised employee laptops to code distribution systems and development infrastructure." The Google-owned cloud security company is tracking the activity under the moniker JINX-0164 . The threat actor is assessed to be active since at least mid-2025 and motivated by financial gain, targeting developers through recruitment-themed and other social engineering techniques to siphon cryptocurrencies. In at least one case, the adversary is said t...

Cybersecurity researchers have discovered a new malicious package on the npm registry that comes with information stealing capabilities. According to OX Security, the package, named " mouse5212-super-formatter ," is designed to upload files from "/mnt/user-data," a dedicated directory used by Anthropic's Claude artificial intelligence (AI) tool to handle uploads and outputs in the background. The activity has been codenamed Malware-Slop . "By analyzing the malware, it turns out that the script presents itself as an internal 'archive deployment sync' utility that validates or initializes a GitHub repository, captures a lightweight 'network status' snapshot, and then performs a structured synchronization of local workspace files into a remote tracking tree," researchers Moshe Siman Tov Bustan and Nir Zadok said . In reality, however, it authenticates to GitHub during the postinstall stage, either using a GitHub access token found i...

CrowdStrike, in partnership with Google and the Shadowserver Foundation, has announced the simultaneous disruption of all command-and-control (C2) channels associated with GlassWorm , a persistent software chain campaign targeting software developers through malicious packages and extensions. "Since at least early 2025, GlassWorm operators have systematically targeted software developers, a population with access to source code repositories, cloud platforms, CI/CD pipelines, and package registries," CrowdStrike said . The development comes as developers have increasingly become lucrative targets for pulling off software supply chain attacks, enabling attackers to leverage a single compromised workstation to impact thousands of downstream organizations and users at once. GlassWorm, since its emergence last year, has conducted a "multi-pronged campaign" using trojanized VS Code extensions published on both the Microsoft VS Code Marketplace and Open VSX, ther...

A new coordinated cross-ecosystem software supply chain attack campaign has targeted npm, PyPI, and Crates.io to distribute credential-stealing malware. The campaign, codenamed TrapDoor , spans more than 34 malicious packages across over 384 versions. The earliest activity was recorded on May 22, 2026, at 8:20 p.m. UTC, with new packages published to the ecosystems in waves from a cluster of accounts in quick succession. "TrapDoor targets developers in crypto, DeFi, Solana, and AI communities," Socket said. "The malicious packages are designed to steal developer secrets, crypto wallets, SSH keys, cloud credentials, browser data, and environment variables." "Several npm packages also deploy a shared payload, trap-core.js, that scans for credentials, validates AWS and GitHub tokens, attempts SSH-based lateral movement, and plants persistence through .cursorrules, CLAUDE.md, Git hooks, shell hooks, systemd, cron, and SSH." It's worth noting tha...

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...

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...

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 ...

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. "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 Search API as a dead drop resolver for receiving further comm...

In yet another software supply chain attack, threat actors have compromised the popular GitHub Actions workflow, actions-cool/issues-helper , to run malicious code that harvests sensitive credentials and exfiltrates them to an attacker-controlled server. "Every existing tag in the repository has been moved to point to an imposter commit that does not appear in the action's normal commit history," StepSecurity researcher Varun Sharma said . "That commit contains malicious code that exfiltrates credentials from CI/CD pipelines that run the action." An imposter commit refers to a deceptive software supply chain attack strategy in which malicious code is injected into a project by referencing a commit or tag that exists only in an adversary-controlled fork, rather than the original trusted repository. As a result, attackers can bypass standard Pull Request (PR) reviews and achieve arbitrary code execution. The imposter commit, per the cybersecurity company, ...

Cybersecurity researchers have discovered a fresh software supply chain attack campaign that has compromised various npm packages associated with the @antv ecosystem as part of the ongoing Mini Shai-Hulud attack wave. "The attack affects packages tied to the npm maintainer account atool, including echarts-for-react, a widely used React wrapper for Apache ECharts with roughly 1.1 million weekly downloads," Socket said . The list of affected packages include @antv packages such as @antv/g2, @antv/g6, @antv/x6, @antv/l7, @antv/s2, @antv/f2, @antv/g, @antv/g2plot, @antv/graphin, and @antv/data-set, as well as related packages outside the @antv namespace, including echarts-for-react, timeago.js, size-sensor, canvas-nest.js, and others. The application security company said the tradecraft matches Mini Shai-Hulud, where a compromised maintainer account is leveraged to push out trojanized versions in quick succession. The development comes as the supply chain attack campaign...

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 ...

Cybersecurity researchers are sounding the alarm about what has been described as "malicious activity" in newly published versions of node-ipc. According to Socket and StepSecurity , three different versions of the npm package have been confirmed as malicious - node-ipc@9.1.6 node-ipc@9.2.3 node-ipc@12.0.1 "Early analysis indicates that node-ipc@9.1.6, node-ipc@9.2.3, and node-ipc@12.0.1 contain obfuscated stealer/backdoor behavior," Socket said. "The malware appears to fingerprint the host environment, enumerate and read local files, compress and chunk collected data, wrap the payload in a cryptographic envelope, and attempt exfiltration through a network endpoint selected via DNS/address logic." StepSecurity said the heavily obfuscated payload is triggered when the package is required at runtime, and attempts to exfiltrate a broad set of developer and cloud secrets to an external command-and-control (C2) server. This includes 90 categories ...

TeamPCP , the threat actor behind the recentsupply chain attack spree, has been linked to the compromise of the npm and PyPI packages from TanStack, UiPath, Mistral AI, OpenSearch, and Guardrails AI as part of a fresh Mini Shai-Hulud campaign. The affected npm packages have been modified to include an obfuscated JavaScript file ("router_init.js") that's designed to profile the execution environment and launch a comprehensive credential stealer capable of targeting cloud providers, cryptocurrency wallets, AI tools, messaging apps, and CI systems, including Github Actions, multiple reports from Aikido Security , Endor Labs , SafeDep , Socket , StepSecurity , and Snyk show. The data is exfiltrated to the "filev2.getsession[.]org" domain. Using Session Protocol infrastructure is a deliberate attempt on the part of the attackers to evade detection, as the domain is unlikely to be blocked within enterprise environments, given that it belongs to a decentralize...

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...

Cybersecurity researchers have discovered malicious code in an npm package after a malicious package as a dependency to the project by Anthropic's Claude Opus large language model (LLM). The package in question is " @validate-sdk/v2 ," which is listed on npm as a utility software development kit (SDK) for hashing, validation, encoding/decoding, and secure random generation. However, its real functionality is to plunder sensitive secrets from the compromised environment. The package, which shows signs of being vibe-coded using generative artificial intelligence (AI), was first uploaded to the repository in October 2025. The malware campaign has been codenamed PromptMink by ReversingLabs, which linked the activity as part of a broader campaign mounted by the North Korean threat actor known as Famous Chollima (aka Shifty Corsair), which is behind the long-running Contagious Interview campaign and the fraudulent IT Worker scam . "The new malware campaign [...] inv...

Cybersecurity researchers have flagged a fresh set of packages that have been compromised by bad actors to deliver a self-propagating worm that spreads through stolen developer npm tokens. The supply chain worm has been detected by both Socket and StepSecurity , with the companies tracking the activity under the name CanisterSprawl owing to the use of an ICP canister to exfiltrate the stolen data, in a tactic reminiscent of TeamPCP's CanisterWorm to make the infrastructure resilient to takedowns. The list of affected packages is below - @automagik/genie (4.260421.33 - 4.260421.40) @fairwords/loopback-connector-es (1.4.3 - 1.4.4) @fairwords/websocket (1.0.38 - 1.0.39) @openwebconcept/design-tokens (1.0.1 - 1.0.3) @openwebconcept/theme-owc (1.0.1 - 1.0.3) pgserve (1.1.11 - 1.1.14) The malware is triggered during install time via a postinstall hook to steal credentials and secrets from developer environments, and then leverage the stolen npm tokens to push poisoned ver...

Cybersecurity researchers have discovered 36 malicious packages in the npm registry that are disguised as Strapi CMS plugins but come with different payloads to facilitate Redis and PostgreSQL exploitation, deploy reverse shells, harvest credentials, and drop a persistent implant. "Every package contains three files (package.json, index.js, postinstall.js), has no description, repository, or homepage, and uses version 3.6.8 to appear as a mature Strapi v3 community plugin," SafeDep said . All identified npm packages follow the same naming convention, starting with "strapi-plugin-" and then phrases like "cron," "database," or "server" to fool unsuspecting developers into downloading them. It's worth noting that the official Strapi plugins are scoped under "@strapi/." The packages, uploaded by four sock puppet accounts "umarbek1233," "kekylf12," "tikeqemif26," and "umar_bektembiev1...

The maintainer of the Axios npm package has confirmed that the supply chain compromise was the result of a highly-targeted social engineering campaign orchestrated by North Korean threat actors tracked as UNC1069 . Maintainer Jason Saayman said the attackers tailored their social engineering efforts "specifically to me" by first approaching him under the guise of the founder of a legitimate, well-known company. "They had cloned the company's founders' likeness as well as the company itself," Saayman said in a post-mortem of the incident. "They then invited me to a real Slack workspace. This workspace was branded to the company's CI and named in a plausible manner. The Slack [workspace] was thought out very well; they had channels where they were sharing LinkedIn posts." Subsequently, the threat actors are said to have scheduled a meeting with him on Microsoft Teams. Upon joining the fake call, he was presented with a fake error mes...

Google has formally attributed the supply chain compromise of the popular Axios npm package to a financially motivated North Korean threat activity cluster tracked as UNC1069 . "We have attributed the attack to a suspected North Korean threat actor we track as UNC1069," John Hultquist, chief analyst at Google Threat Intelligence Group (GTIG), told The Hacker News in a statement. "North Korean hackers have deep experience with supply chain attacks, which they've historically used to steal cryptocurrency. The full breadth of this incident is still unclear, but given the popularity of the compromised package, we expect it will have far reaching impacts." The development comes after threat actors seized control of the package maintainer's npm account to push two trojanized versions 1.14.1 and 0.30.4 that introduced a malicious dependency named "plain-crypto-js" in order to deliver a cross-platform backdoor capable of infecting Windows, macOS, an...
