🛡️ McAfee Labs reports a MaaS campaign called Weedhack that has been active since January 2026, using SEO poisoning and YouTube videos to trick Minecraft users into downloading malicious JAR files. The malware chain begins with a trojanized client and leverages the Ethereum blockchain for C2 resolution, ultimately delivering remote access and information-stealing payloads. The service is offered free and as a paid tier, enabling widespread abuse, account theft, and cyberbullying against younger victims.

🛡️ McAfee researchers report that a large-scale malware campaign named WeedHack has infected more than 116,000 systems by distributing malicious Minecraft mods, clients, cheats, and utilities via YouTube links and SEO poisoning. The operation provides a free, clear-net MaaS dashboard and a paid premium tier that adds remote control, keylogging, and webcam access, targeting session IDs, browsers, wallets, and gaming credentials. Victims are concentrated in the US, Germany, India, and the UK, and the campaign uses hundreds of distribution URLs and thousands of malicious JARs. Players are urged to only download from official sources and use the in-game Marketplace for safety.

🛡️ Researchers discovered a malicious npm package named codexui-android that impersonated an OpenAI Codex UI and exfiltrated developer authentication tokens. The package was published to npm with malicious code absent from the project's public GitHub repository, highlighting risks in artifact distribution. Security experts warn this pattern exploits trust in legitimate-looking developer tooling and reveals blind spots in software supply chain controls.

🛡️ Cybercriminals are exploiting demand for live sports streaming by distributing fake Android IPTV apps that hide malware. These malicious APKs often mimic legitimate services and load real sites in a built-in browser to avoid suspicion while performing background theft. Researchers observed strains like Massiv and the more advanced Perseus, which abuse Android Accessibility Services to steal banking and crypto credentials. Users in Portugal, Spain, France and Türkiye have been targeted; avoid third-party APKs and keep devices updated.

🛡️ FortiGuard Labs uncovered a phishing campaign using purchase-order-themed emails to deliver a RAR attachment containing an obfuscated JavaScript file that drops and executes a PowerShell script. The PowerShell payload employs fileless techniques and process hollowing to load .NET modules into a suspended MsBuild.exe process, which then extracts and runs a downloader module. The downloader retrieves a fileless PureLogs plugin from a C2 server to harvest credentials, browser data, Discord tokens, and cryptocurrency wallet information before encrypting and exfiltrating it.

🚨 A Bitdefender report warns that cybercriminals have built extensive ecosystems to scam Formula 1 fans, exploiting the sport’s fast-moving digital culture. Scams include counterfeit merchandise, fake grand prix tickets, illegal streaming apps and boxes, social media fraud and distribution of infostealer malware. Fans may also be coerced into botnets for DDoS attacks. Bitdefender urges vigilance and recommends anti-phishing and antivirus tools to reduce risk.

🔒 GitHub confirmed an intrusion into internal repositories after an employee device was compromised by a poisoned version of the Nx Console VS Code extension published as nrwl.angular-console. The attacker, tracked as TeamPCP, exfiltrated approximately 3,800 repositories; GitHub says it rotated critical secrets and is monitoring for follow-on activity. The trojanized release was available for only 18 minutes but delivered a credential stealer targeting 1Password, Anthropic Claude Code, npm, GitHub and AWS.

🔍 Ukrainian cyberpolice, working with U.S. law enforcement, say they identified an 18-year-old from Odesa suspected of running an infostealer operation that infected customers of a California online store between 2024 and 2025. The malware harvested browser sessions, credentials, and payment information, compromising 28,000 accounts. Attackers used 5,800 accounts to make unauthorized purchases totaling about $721,000, and authorities executed searches seizing phones, computers, storage media, bank cards, and cryptocurrency-related evidence while the investigation continues.

🛡️ SentinelOne researchers describe a new SHub variant named Reaper that targets macOS users by impersonating Apple, Google, and Microsoft across a single attack chain. The campaign uses fake security alerts and a ClickFix-style workflow to trick victims into running malicious AppleScript via the applescript:// URI handler and the Script Editor, bypassing Terminal paste protections. Reaper performs environment checks, drops payloads, and establishes persistence through LaunchAgents, then harvests credentials, Keychain items, cryptocurrency wallets, and messaging data. Defenders are advised to shift toward behavior-based detection and monitor Script Editor, osascript, and suspicious LaunchAgent activity.

🔎 Unit 42 documents clusters of TamperedChef-style campaigns that trojanize productivity tools (e.g., PDF editors, calendars) to deliver stealers, RATs and proxies. These operations use malvertising-driven distribution, legitimate-looking sites, frequent binary rebuilds and code signing to evade detection. We tracked three clusters (CL-CRI-1089, CL-UNK-1090, CL-UNK-1110), over 4,000 samples and 100 variants. If compromised, contact the Unit 42 Incident Response team for assistance.

🔍 On April 22 a trojanized Bitwarden CLI briefly appeared on npm, harvesting developer tokens via a compromised GitHub Action tied to the Checkmarx supply‑chain incident. Bitwarden later issued CVE‑2026‑42994, but the author notes the CVE was retroactive and did not imply a patchable defect. The piece argues CVE’s artifact‑centric model struggles with agentic and model‑mediated threats that mutate behaviorally and often evade dashboards.

🔒 Microsoft exposed and disrupted Fox Tempest, a criminal service selling malware-signing-as-a-service that helped disguise malware like Oyster, Lumma Stealer and Vidar as legitimate software. The Digital Crimes Unit used undercover personas to map the group's infrastructure and worked with hosting providers to sinkhole domains, disable virtual machines and suspend accounts. Microsoft filed a civil action in early May and unsealed a New York case on May 19.

🛡️ A compromised version of the Nx Console extension (rwl.angular-console v18.95.0) published to the Microsoft VS Code Marketplace delivered a multi-stage credential stealer and supply-chain poisoning payload to developers' machines. The obfuscated 498 KB payload, pulled from an orphaned commit in the official nrwl/nx GitHub repo, installs the Bun runtime and a Python backdoor on macOS while exfiltrating secrets via HTTPS, GitHub API and DNS tunneling. The maintainers traced the incident to a developer whose GitHub credentials were exposed, revoked access, and advised users to update to v18.100.0 or later and rotate exposed tokens and keys.

🐛 Researchers have uncovered a software supply chain campaign—part of the Mini Shai-Hulud wave—that pushed trojanized updates across the @antv npm ecosystem. The compromise traces to the maintainer account "atool" and affected popular modules including echarts-for-react and many @antv packages. The stealer harvests a wide range of cloud, developer and payment credentials and abuses stolen tokens to republish malicious versions, creating broad downstream exposure for organizations that automatically update dependencies.

🔔 SentinelOne researchers disclosed a new SHub macOS infostealer variant, dubbed Reaper, that lures victims with fake app installers and uses the applescript:// URL scheme to launch a malicious AppleScript. The payload displays a bogus Apple security update, requests the macOS password, and executes a shell script that harvests browser data, crypto wallets, passwords, iCloud and Telegram artifacts, and files from Desktop and Documents. Reaper also persists via a LaunchAgent, hijacks wallet apps by replacing core files, and clears quarantine flags to evade Gatekeeper.

⚠️ OXsecurity identified four malicious npm packages published by account deadcode09284814, including typosquatted modules aimed at Axios users. One package, chalk-tempalte, contains a non-obfuscated clone of the leaked Shai-Hulud infostealer that steals credentials, secrets, and crypto wallet data and exfiltrates it to a known C2. Another package, axois-utils, adds persistent DDoS bot functionality alongside credential theft. Developers should remove affected packages and rotate exposed credentials and API keys immediately.

⚠️ Multiple security firms have flagged newly published versions of the popular node-ipc npm package as malicious, containing obfuscated infostealer code that executes via the CommonJS entrypoint. The compromised releases (9.1.6, 9.2.3, 12.0.1) fingerprint hosts, harvest cloud and developer credentials, compress them, and exfiltrate data via DNS TXT queries. Users should remove affected versions, rotate secrets, and audit caches and lockfiles.

🔒 Subscription services are widespread and often contain personal data, making them attractive targets for attackers. The article outlines common attack vectors — phishing, credential reuse, infostealers, and bulk-resale of hacked family slots — and explains practical defenses: use password managers, enable two-factor authentication or passkeys, and monitor active sessions. It also advises how to spot phishing and track hidden recurring charges through bank statements and app-store settings.

🔍 Researchers at Palo Alto Networks' Unit 42 say the Gremlin stealer has progressed from a basic credential harvester into a modular, stealth-oriented toolkit. New builds embed payloads in the .NET resource section and apply XOR obfuscation to evade static and heuristic detection. The threat continues to exfiltrate data via private web panels and the Telegram Bot API, while adding Discord token theft, a clipboard-based crypto clipper, and WebSocket session hijacking.

🛡️ FortiGuard Labs details a phishing campaign that uses TXZ attachments and environment-variable obfuscation to execute a fileless .NET loader. The loader, tracked as PawsRunner, retrieves encrypted payloads hidden inside PNG images using steganography and delivers the PureLogs infostealer. The campaign abuses multiple network APIs, prioritizes image responses, and uses cat images as cover, with final-stage C2 communication via HTTPS.
