Phantom Stealer is a .NET-based credential-harvesting malware that collects browser credentials, saved passwords, session cookies, cryptocurrency wallet files, and system fingerprints from infected machines. Distributed through phishing emails, cracked software, and malicious links on Discord and Telegram, it employs multiple loader variants including steganography-based delivery and PowerShell shellcode injection. The malware uses extensive anti-analysis techniques including virtualization detection, API patching to disable AMSI and ETW, and timing-based sandbox evasion. It targets Chromium and Gecko-based browsers, cryptocurrency wallets, FileZilla credentials, WinSCP configurations, and Outlook profiles. Additional capabilities include keylogging, screen capture, clipboard monitoring with cryptocurrency address replacement, and Wi-Fi credential theft. The malware achieves persistence through registry Run keys or Startup folder entries.

A Windows-based cryptocurrency clipper has been actively targeting users since February 2026, employing sophisticated techniques to steal digital assets. The malware propagates through malicious shortcut files on USB devices, creating a worm-like infection chain. Once deployed, it utilizes Windows Script Host and ActiveX to launch a bundled Tor proxy client, enabling anonymous communication with hidden-service command and control servers. The clipper performs high-frequency clipboard monitoring to intercept cryptocurrency wallet addresses, seed phrases, and private keys, replacing them with attacker-controlled alternatives. Additionally, it captures screenshots for context and maintains persistent access through scheduled tasks. The threat demonstrates advanced capabilities including remote code execution, making it more than a simple stealer by functioning as a lightweight backdoor. The malware employs multiple defense evasion techniques including multi-layer obfuscation, anti-analysis checks, and local S...

Operation DualScript is a sophisticated multi-stage malware campaign targeting cryptocurrency and financial activities. It utilizes Windows Scheduled Tasks, VBScript launchers, and PowerShell execution to maintain persistence while minimizing disk artifacts. The attack operates through two parallel chains: a web-based PowerShell loader deploying a cryptocurrency clipboard hijacker, and a secondary chain executing the RetroRAT implant in memory. RetroRAT monitors user activity, captures keystrokes, and tracks interactions with financial services to harvest sensitive information. The malware employs various anti-analysis techniques and establishes a command-and-control channel for remote access and data exfiltration. This campaign highlights the growing abuse of trusted system utilities and in-memory execution techniques to evade traditional detection mechanisms.

A sophisticated cryptocurrency theft operation, orchestrated by the threat actor 'RedLineCyber', has been uncovered. The actor distributes a malicious executable named 'Pro.exe', a Python-based clipboard hijacking trojan designed for silent cryptocurrency theft. This malware continuously monitors the Windows clipboard for cryptocurrency wallet addresses and substitutes them with attacker-controlled addresses. The threat actor exploits trust within Discord communities focused on gaming, gambling, and cryptocurrency streaming. The malware demonstrates moderate technical complexity, using obfuscated Python bytecode and base64-encoded regular expressions for wallet detection. It targets cryptocurrency streamers, casino gaming communities, and users who frequently handle digital asset transactions during live broadcasts. The operation has successfully compromised multiple victims across six major cryptocurrencies.

A new variant of the XCSSET malware, designed to infect Xcode projects, has been identified with key changes in browser targeting, clipboard hijacking, and persistence mechanisms. This variant employs sophisticated encryption and obfuscation techniques, uses run-only compiled AppleScripts for stealthy execution, and expands its data exfiltration capabilities to include Firefox browser data. It also adds another persistence mechanism through LaunchDaemon entries. The malware features a submodule for monitoring the clipboard and substituting wallet addresses. The infection chain consists of four stages, with modifications to the boot function and introduction of new modules. Changes include additional checks for Firefox browser, modified logic for Telegram existence check, and new info-stealer modules targeting Firefox data.

Cybercriminals have launched a campaign redirecting users from gaming sites and social media to fake Booking.com websites. The scam uses fake CAPTCHA prompts to trick visitors into executing malicious commands on their devices. If successful, the attack downloads and installs AsyncRAT, a backdoor Trojan that allows remote monitoring and control of infected computers. The campaign, which began in mid-May, frequently changes its final redirect destination. The malicious actors exploit the fact that 40% of people book travel through online searches, creating ample opportunities for deception. To stay safe, users are advised to be cautious of website instructions, use anti-malware solutions, employ browser extensions that block malicious domains, and consider disabling JavaScript on unknown websites.
