MioLab, also known as Nova, is a sophisticated Malware-as-a-Service platform targeting macOS environments, heavily advertised on Russian-speaking underground forums. The platform features extensive data exfiltration capabilities, including browser credential theft, cryptocurrency wallet targeting (supporting over 200 browser extensions and 50+ desktop wallets), and a premium module specifically designed to compromise Ledger and Trezor hardware wallets by intercepting 24-word BIP39 recovery seed phrases. The lightweight C-based payload supports both Intel and Apple Silicon architectures across macOS versions from Sierra to Tahoe. MioLab employs sophisticated social engineering through customizable DMG builders with live preview features, fake system prompts, and ClickFix integration. Recent updates demonstrate rapid development, including Safari cookie grabbing, automated Apple Notes decryption, and universal hardware wallet modules. The operation utilizes bulletproof hosting services and shares infrastruct...
Cybercriminals are merging traditional malware operations with cryptocurrency-focused attacks, creating hybrid threat ecosystems. Modern crypto drainers have evolved into automated systems capable of extracting assets across multiple blockchains with minimal user interaction, supported by well-developed underground marketplaces offering drainer-as-a-service kits. Two case studies exemplify this convergence: StepDrainer operates as a multichain drainer-as-a-service platform that abuses Web3Modal and smart contract methods across over 20 blockchain networks, using AI-themed lures and polished interfaces to deceive victims into connecting wallets. EtherRAT represents a hybrid Windows implant delivered through trojanized TFTP installers, combining traditional RAT capabilities with blockchain-aware functionality including Ethereum RPC endpoints and embedded wallet addresses. Both threats demonstrate how cryptocurrency theft infrastructure now intersects with mainstream attack surfaces affecting enterprise envir...
