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...

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[...

Anthropic on Friday disclosed that Project Glasswing has helped uncover more than 10,000 high- or critical-severity vulnerabilities across some of the most "systemically" important software across the world since the cybersecurity initiative went live last month. Project Glasswing is a defensive effort launched by the artificial intelligence (AI) company to secure critical global software infrastructure. It grants a small set of about 50 partners exclusive, early access to Claude Mythos Preview, a frontier model with capabilities to autonomously identify vulnerabilities in widely-used software before bad actors can exploit them. Of these vulnerabilities, 6,202 have been classified as high- or critical-severity flaws impacting more than 1,000 open-source projects. Subsequent analysis of these vulnerability candidates has identified that 1,726 are valid true positives. As many as 1,094 flaws are assessed to be either high- or critical-severity. One of the identified w...

Cybersecurity researchers have flagged a fresh software supply chain attack campaign that has targeted multiple PHP packages belonging to Laravel-Lang to deliver a comprehensive credential-stealing framework. The affected packages include - laravel-lang/lang laravel-lang/http-statuses laravel-lang/attributes laravel-lang/actions "The timing and pattern of the newly published tags point to a broader compromise of the Laravel Lang organization's release process, rather than a single malicious package version," Socket said . "The tags were published in rapid succession on May 22 and May 23, 2026, with many versions appearing only seconds apart." More than 700 versions associated with these packages have been identified, indicating automated mass tagging or republishing. It's suspected that the attacker may have managed to obtain access to organization-level credentials, repository automation, or release infrastructure. What makes the att...

A maximum-severity security vulnerability impacting LiteSpeed User-End cPanel Plugin has come under active exploitation in the wild. The flaw, tracked as CVE-2026-48172 (CVSS score: 10.0), relates to an instance of incorrect privilege assignment that an attacker could abuse to run arbitrary scripts with elevated permissions. "Any cPanel user (including an attacker or a compromised account) may exploit the lsws.redisAble function to execute arbitrary scripts as root," LiteSpeed said . The vulnerability impacts all versions of the plugin between 2.3 and 2.4.4. LiteSpeed's WHM plugin is not impacted. The issue has been addressed in version 2.4.5. Security researcher David Strydom has been credited with discovering and reporting the flaw. LiteSpeed noted that the "vulnerability is being actively exploited," but refrained from sharing additional details. It has provided the following indicator of compromise - grep -rE "cpanel_jsonapi_func=redisAble...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a recently patched critical security flaw impacting Drupal Core to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability in question is CVE-2026-9082 (CVSS score: 6.5), an SQL injection vulnerability affecting all supported versions of Drupal Core. "Drupal Core contains a SQL injection vulnerability that could allow for privilege escalation and remote code execution via specially crafted requests sent with the database abstraction API," CISA said. News of exploitation arrives less than two days after Drupal released fixes for the flaw. Patches are available for the following versions - Drupal 11.3.10 Drupal 11.2.12 Drupal 11.1.10 Drupal 10.6.9 Drupal 10.5.10 Drupal 10.4.10 Drupal 9.5 (Manual patching required) Drupal 8.9 (Manual patching required) In an update to its advisory on May 22, 2026, Drupal acknowl...

Authorities in Europe and North America have announced the dismantling of a criminal virtual private network (VPN) service used by criminal actors to obscure the origins of ransomware attacks, data theft, scanning, and denial-of-service attacks. Codenamed Operation Saffron, the disruption of First VPN Service was led by France and the Netherlands, with several other nations supporting the investigation since December 2021, including Luxembourg, Romania, Switzerland, Ukraine, the U.K., Canada, Germany, the U.S., Spain, Sweden, Denmark, Estonia, Latvia, Lithuania, Poland, and Portugal. First VPN, per Europol , offered services designed specifically for criminal use, allowing anonymous payments and a hidden infrastructure that enabled paying customers to hide their identities when carrying out ransomware attacks, large-scale fraud, and data theft. It was promoted on Russian-speaking cybercrime forums such as Exploit[.]in and XSS[.]is as a tool to evade law enforcement. The inte...

The Belarus-aligned threat actor known as Ghostwriter (aka UAC-0057 and UNC1151) has been observed using lures related to Prometheus, a Ukrainian online learning platform, to target government organizations in the country. The activity, per the Computer Emergency Response Team of Ukraine (CERT-UA), involves sending phishing emails to government entities using compromised accounts. It's been active since the spring of 2026. "Typically, the email contains a PDF attachment with a link that, when clicked, leads to the download of a ZIP archive containing a JavaScript file," the agency said in a Thursday report. The JavaScript file, dubbed OYSTERFRESH, is designed to display a decoy document as a distraction mechanism, while stealthily writing an obfuscated and encrypted payload called OYSTERBLUES to the Windows Registry, as well as downloading and launching OYSTERSHUCK, which is responsible for decoding OYSTERBLUES.

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...

1 Introduction This article provides a technical analysis of how many Windows kernel mode drivers can be interacted with from user mode without the hardware they were developed for. This work was motivated by driver-oriented vulnerability research and the need to evaluate the exploitability of individual findings, which frequently affect code whose reachability is hardware-gated. The methodology presented here should help anyone determine whether a particular Windows kernel mode driver vulnerability remains reachable - and thus potentially exploitable - even in the absence of the hardware the driver was developed for. The reader is expected to have basic Windows driver knowledge, especially regarding device objects. The rest of this article is written with the assumption that the reader is already familiar with the concepts described in the introduction article: Anatomy of Access: Windows Device Objects from a Security Perspective . Just like the introduction article, this resou...

The U.S. Department of Justice (DoJ) on Thursday announced the arrest of a Canadian man in connection with allegedly operating a distributed denial-of-service (DDoS) botnet known as Kimwolf . In tandem, Jacob Butler (aka Dort), 23, Ottawa, Canada, has been charged with offenses related to the development and operation of the botnet. Kimwolf is assessed to be a variant of AISURU that specifically infected Android devices with an exposed Android Debug Bridge (ADB) service. "Kimwolf targeted infected devices which were traditionally 'firewalled' from the rest of the internet, such as digital photo frames and web cameras," the DoJ said . "The infected devices were enslaved by the botnet operators." "The operators then used a 'cybercrime-as-a-service' model to sell access to the infected devices to other cybercriminals. The operators and their customers forced the victim devices to participate in DDoS attacks, targeting computers and servers l...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added two security flaws impacting Langflow and Trend Micro Apex One to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities in question are listed below - CVE-2025-34291 (CVSS score: 9.4) - An origin validation error vulnerability in Langflow that could allow an attacker to execute arbitrary code and achieve full system compromise. CVE-2026-34926 (CVSS score: 6.7) - A directory traversal vulnerability in on-premise versions of Trend Micro Apex One that could allow a pre-authenticated local attacker to modify a key table on the server to inject malicious code to deploy to agents on affected installations. In a report published in December 2025, Obsidian Security said CVE-2025-34291 exploits three combined weaknesses: overly Permissive CORS, lack of cross-site request forgery (CSRF) protection, and an endpoint that allows code execution...

Cisco has rolled out updates for a maximum-severity security flaw impacting Secure Workload that could allow an unauthenticated, remote attacker to access sensitive data. Tracked as CVE-2026-20223 (CVSS score: 10.0), the vulnerability arises from insufficient validation and authentication when accessing REST API endpoints. "An attacker could exploit this vulnerability if they are able to send a crafted API request to an affected endpoint," Cisco said . "A successful exploit could allow the attacker to read sensitive information and make configuration changes across tenant boundaries with the privileges of the Site Admin user." The shortcoming impacts Cisco Secure Workload Cluster Software on SaaS and on-prem deployments, regardless of device configuration. Cisco said there are no workarounds that address the vulnerability. The issue has been addressed in the following versions - Cisco Secure Workload Release 3.9 and earlier (Migrate to a fixed releas...

Cybersecurity researchers have disclosed details of a new Linux malware dubbed Showboat that has been put to use in a campaign targeting a telecommunications provider in the Middle East since at least mid-2022. "Showboat is a modular post-exploitation framework designed for Linux systems, capable of spawning a remote shell, transferring files, and functioning as a SOCKS5 proxy," Lumen Technologies Black Lotus Labs said in a report shared with The Hacker News. It's assessed that the malware has been employed by at least one, and possibly more, threat activity clusters affiliated with China, with correlations identified between command-and-control (C2) nodes and IP addresses geolocated to Chengdu, the capital city of the Chinese province of Sichuan. One such threat actor is Calypso (aka Bronze Medley and Red Lamassu), which is known to be active since at least September 2016, targeting state institutions in Brazil, India, Kazakhstan, Russia, Thailand, and Turkey. ...

This week starts small. A token leaks. A bad package slips in. A login trick works. An old tool shows up again. At first, it feels like the usual mess. Then you see the pattern: attackers are not always breaking in. They are using the parts we already trust. That is what makes it worrying. The danger is in normal things now - updates, apps, cloud buttons, support chats, trusted accounts. AI does not make the attacks magic. It just helps people try more things, faster. Here's what showed up this week. 47 zero-days exposed 47 0-Days Discovered in Pwn2Own Berlin 2026 The Pwn2Own Berlin 2026 hacking contest has concluded, with security researchers collecting $1,298,250 in rewards after exploiting 47 zero-day flaws in various products from Windows, Linux, VMware, and NVIDIA. DEVCORE won the event with 50.5 Master of Pwn points and $505,000 in rewards throughout the three-day contest after hacking Microsoft SharePoint, Microsoft E...

Consider a cached access key on a single Windows machine. It got there the way most cached credentials do - a user logged in, and the key stored itself automatically. Standard AWS behavior. No one misconfigured anything or violated a policy. Yet that single key, which was easily accessible to a minor-league attacker, could have opened a path to some 98% of entities in the company's cloud environment - nearly every critical workload the business depended on.  This real-world exposure was caught before an attacker could use it. But the takeaway is clear: identity itself, and every permission it carries, has become the attack path. Your environment runs on identity. Active Directory, cloud identity providers, service accounts, machine identities, and AI agents - all of these carry permissions that span systems and trust boundaries. A single stolen credential hands the attacker a legitimate identity - along with every permission attached to it.  Despite this, most security pro...

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...

Drupal has released security updates for a "highly critical" security vulnerability in Drupal Core that could be exploited by attackers to achieve remote code execution, privilege escalation, or information disclosure. The vulnerability, now tracked as CVE-2026-9082 , carries a CVSS score of 6.5 out of 10.0, per CVE.org. Drupal said the vulnerability resides in a database abstraction API that is used in Drupal Core to validate queries and ensure they are sanitized against SQL injection attacks. "A vulnerability in this API allows an attacker to send specially crafted requests, resulting in arbitrary SQL injection for sites using PostgreSQL databases," it said . "This can lead to information disclosure, and in some cases privilege escalation, remote code execution, or other attacks." Drupal noted the security flaw can be exploited by anonymous users, and impacts only sites that use PostgreSQL. The following versions address the issue - Drupal 11.3.10 ...

Microsoft has unveiled two new open-source tools called RAMPART and Clarity to assist developers in better testing the security of artificial intelligence (AI) agents. RAMPART , short for Risk Assessment and Measurement Platform for Agentic Red Teaming, functions as a Pytest-native safety and security testing framework for writing and running safety and security tests for AI agents, covering both adversarial and benign issues, as well as various harm categories. Users can write test cases to attack or probe an AI agent to explore possible safety violations like cross-prompt injections, where untrusted data reaches an AI system indirectly via a data source (e.g., email, file, or a web page) processed by it, or unintended behavioral regressions and data exfiltration. RAMPART then evaluates the outcome of those tests and reports the results. All it needs is an adapter that connects an agent to the test suite. The tool builds on PyRIT (short for Python Risk Identification Tool), ...
