🛡️Kaspersky and analysts observed unknown actors briefly compromise CPUID, swapping legitimate download links for trojanized installers of CPU‑Z and HWMonitor for under 24 hours. The malicious packages contained a signed executable alongside a malicious CRYPTBASE.dll that leveraged DLL side‑loading, performed anti‑sandbox checks and fetched additional payloads. The campaign deployed STX RAT, a feature‑rich RAT with HVNC and extensive infostealer and remote‑control capabilities, impacting individuals and organizations in multiple sectors.

🐛 A new phase of the GlassWorm campaign uses a Zig-compiled native Node addon embedded in a malicious Open VSX extension named specstudio.code-wakatime-activity-tracker, impersonating WakaTime, to gain OS-level access and stealthily install additional payloads. The addon (installed as win.node on Windows and mac.node on macOS) runs outside the JavaScript sandbox, locates IDEs that support VS Code extensions, downloads a malicious VSIX from an attacker-controlled GitHub account, and silently installs it across detected editors. The second-stage extension then reads commands from the Solana blockchain to obtain its C2, exfiltrates sensitive data, and deploys a RAT that ultimately installs an information-stealing Chrome extension; affected users should assume compromise and rotate secrets.

🔐 Google has introduced Device Bound Session Credentials (DBSC) protection in Chrome 146 for Windows to block infostealer malware from harvesting session cookies. The feature cryptographically ties session cookies to hardware-backed keys stored in the Trusted Platform Module (TPM) on Windows, with macOS support planned for a future release. Because the per-session private keys are generated by a security chip and cannot be exported, exfiltrated cookies become useless without proof of key possession. The protocol is privacy-conscious, uses distinct keys per session to avoid cross-site correlation, and was developed with industry input including Microsoft.

🛡️ Jamf Threat Labs has identified a macOS malware campaign delivering the Atomic Stealer (AMOS) infostealer/backdoor using a ClickFix social engineering technique that now leverages Script Editor instead of Terminal. Attackers display fake Apple guidance in a browser window to convince users to paste and run malicious commands, bypassing Terminal paste-scanning warnings added in the macOS 26.4 update. Network defenders are advised to restrict clipboard and run-dialog use, limit execution of untrusted binaries, and block suspicious adverts and sites.

⚠️ Researchers at Jamf observed a ClickFix variation that uses the built-in Script Editor and the applescript:// URL scheme to deliver the Atomic Stealer (AMOS) to macOS users. Victims are lured to fake Apple-themed pages that launch Script Editor with prefilled AppleScript executing an obfuscated "curl | zsh" chain, avoiding the need to open Terminal. The delivered code decodes a base64+gzip payload, writes a Mach-O binary to /tmp/helper, strips extended attributes with "xattr -c", makes it executable, and runs it. Treat Script Editor prompts as high risk and follow official Apple troubleshooting guidance rather than third-party guides.

🔒 Organizations must move beyond checkbox breach monitoring to defend against fast-moving infostealers. Ran Geva (CEO, Webz.io & Lunar) warns that monthly scans and reliance on MFA, EDR, or zero-trust alone often miss stolen credentials, session cookies, and stealer logs. With 4.17 billion compromised credentials observed in 2025 and high breach costs, enterprises need continuous, forensic-grade monitoring, automated triage, and integrations that can reset credentials and invalidate sessions quickly.

🔒 TeamPCP's March 2026 compromise of LiteLLM packages on PyPI injected infostealer malware into versions 1.82.7 and 1.82.8 that ran during installs and updates. The malware harvested plaintext SSH keys, cloud credentials (AWS, Azure, GCP), Docker configs, IDE and agent memory files, and other local secrets, exploiting transitive dependencies. PyPI removed the packages within hours, but many downstream packages would have triggered execution. Use ggshield, pre-commit hooks, and filesystem scanning to detect and contain local secrets.

🛡️Security researchers have discovered an updated SparkCat trojan on both the Apple App Store and Google Play Store, hiding inside seemingly benign apps such as enterprise messengers and food delivery services. Kaspersky said it found two infected iOS apps and one Android app that primarily target cryptocurrency users in Asia. The iOS variant scans photo galleries for English wallet mnemonic phrases, while the Android version employs code virtualization, cross-platform languages and regional keyword scanning for Japanese, Korean and Chinese. Both samples use an OCR module to exfiltrate images containing recovery phrases to attacker-controlled servers, underscoring a rapidly evolving threat.

⚠️ Threat actors are exploiting the recent Claude Code source-code leak to distribute the Vidar infostealer via fake GitHub repositories. Anthropic accidentally exposed a 59.8 MB JavaScript source map on March 31 that revealed 513,000 lines of TypeScript across 1,906 files, and copies rapidly proliferated on GitHub. Zscaler found a malicious repo optimized for search that lures users to download a 7‑Zip archive containing a Rust dropper, ClaudeCode_x64.exe, which deploys Vidar and the GhostSocks proxy. The archive is updated frequently and may carry additional payloads.

🔒 Researchers at Varonis have uncovered Storm, a new infostealer that harvests browser credentials, session cookies and crypto wallets before exfiltrating encrypted data to attacker-controlled servers. Emerging on underground forums in early 2026 and detailed in an April 1 report by Daniel Kelley, Storm shifts decryption off-host to avoid detection and supports both Chromium and Gecko-based browsers. It operates in memory, automates session restoration using Google refresh tokens and SOCKS5 proxies, and is marketed to attackers for under $1,000 per month.

🔒 A new malware-as-a-service called CrystalRAT (also marketed as CrystalX) has been active since January and is being promoted on Telegram and a dedicated YouTube channel, offering remote access, data theft, keylogging, clipboard hijacking and an extensive set of prankware functions. Kaspersky researchers found strong similarities to WebRAT (Salat Stealer), noting a Go-based codebase, matching panel design and a bot-driven sales system; the kit includes a builder, geoblocking, executable customization and anti-analysis protections. Payloads are zlib-compressed and ChaCha20-encrypted, connect to C2 over WebSocket, and the RAT supports CMD execution, VNC-backed remote control, audio/video capture, streaming keylogging and a clipboard clipper; the infostealer component targeting Chromium-based browsers and desktop apps is currently being upgraded. Users should avoid untrusted downloads and apply standard endpoint protections to reduce infection risk.

🔐 Venom Stealer is a malware-as-a-service platform that automates credential harvesting and continuous data exfiltration, marketed on cybercrime forums with subscriptions from $250/month to $1,800 for lifetime access. Researchers at BlackFog report the product integrates ClickFix social-engineering templates into its operator panel, enabling attackers to orchestrate fake Cloudflare CAPTCHAs, update prompts and other lures that trick users into executing payloads. Once active the stealer persistently monitors Chromium- and Firefox-based stores for new credentials, harvests cookies, autofill, browsing history and wallet data, and forwards information to GPU-backed cracking and automated transfer systems.

🛡️ A coordinated phishing campaign attributed to Brazilian operators known as Augmented Marauder and Water Saci is targeting Spanish-speaking users across Latin America and Europe to deliver Windows banking trojans, notably Casbaneiro, using a secondary spreader named Horabot. The attack begins with court-summons-themed emails containing password‑protected PDFs that link to ZIP archives which deploy HTA, VBS, and AutoIt loaders to unpack encrypted payloads. Researchers at BlueVoyant say the threat actor combines WhatsApp automation, ClickFix social engineering, and an email‑hijacking engine that forges bespoke PDFs via a remote API and abuses compromised Outlook accounts to forward tailored phishing messages.

🚨 Hambardzum Minasyan has been extradited to the United States and charged over his alleged role as a principal developer of RedLine, a prolific infostealing malware. Prosecutors say he set up virtual servers, domains and a cryptocurrency account to distribute and monetize the malware and provided customer support to affiliates. The arrest follows the international Operation Magnus seizure of RedLine infrastructure, which yielded a database that aided investigators. Authorities urge organizations and individuals to strengthen cybersecurity and review the Operation Magnus resources to check for exposed credentials.

⚠️ Unit 42 describes a multi-stage supply chain campaign by TeamPCP that compromised widely used security and developer tooling, including Trivy, KICS, LiteLLM, and the Telnyx Python SDK. The attackers injected infostealer payloads into GitHub Actions and PyPI/npm packages to harvest cloud tokens, SSH keys, Kubernetes secrets, and LLM API keys while preserving normal tool behavior. The operation leveraged decentralized ICP canisters for resilient C2 and deployed a worm/wiper named CanisterWorm, prompting urgent CI/CD and cloud identity hardening guidance.

🔍Phantom Stealer, a .NET-based infostealer sold as part of a commercial cybercrime toolkit, harvests browser credentials, cookies, saved passwords, autofill and payment card details as well as messaging and email session data from infected systems. Group-IB observed a sustained phishing campaign between November 2025 and January 2026 that targeted logistics, manufacturing and technology organizations across Europe in five waves. Emails impersonated an equipment trading company and carried archive attachments with obfuscated JavaScript droppers or malicious executables. Indicators such as SPF failures, missing DKIM, reused templates and consistent spelling mistakes pointed to automated, template-driven stealer-as-a-service activity, with stolen data exfiltrated via messaging platforms, SMTP and FTP.

⚠️Researchers at Malwarebytes detail a macOS info-stealing campaign that uses a Python payload compiled into a native binary with Nuitka, delivered via a ClickFix page impersonating Cloudflare. Victims are tricked into pasting a base64-obfuscated curl command into Terminal, which boots a staged installer that removes quarantine flags and launches a Nuitka loader. The loader contains a compressed payload and performs anti-analysis checks before harvesting browser credentials, Keychain entries, cryptocurrency wallets and developer secrets.

⚠️A backdoored release of the Telnyx Python SDK on PyPI was used to deploy credential-stealing malware hidden inside WAV audio files. Security firms Aikido, Socket, and Endor Labs attribute the tampering to TeamPCP, which published versions 4.87.1 and 4.87.2; the latter contained a functioning payload. The malicious code executes on import from telnyx/_client.py and uses steganography to XOR-decode a WAV-hosted second stage that harvests SSH keys, cloud tokens, wallets, environment variables, and Kubernetes secrets. Developers are advised to revert to Telnyx 4.87.0 and treat any systems importing the affected releases as compromised.

🎧 TeamPCP published two malicious telnyx PyPI releases (4.87.1 and 4.87.2) on March 27, 2026 that harvest and exfiltrate credentials using audio steganography embedded in .WAV files. The trojanized code executes on import via modifications to telnyx/_client.py, targets Windows, Linux and macOS, and minimizes forensic traces through in-memory execution and encrypted HTTP exfiltration. PyPI has quarantined the project; users should downgrade to 4.87.0, rotate secrets, and audit affected environments.

🔒 Hambardzum Minasyan, an Armenian national, was extradited to the United States and charged with helping administer the RedLine infostealer operation. U.S. prosecutors allege he registered virtual private servers, domains, a cryptocurrency account used for affiliate payments, and file-sharing repositories that distributed the malware. He is accused of managing command-and-control infrastructure, assisting affiliates, and conspiring to launder proceeds, and faces multiple federal counts with a potential prison term if convicted.
