Miolab Stealer

Miolab, also known as Nova, is an advanced information stealer specifically engineered to target macOS users. Distributed through hacker forums under the Malware-as-a-Service (MaaS) model, it enables cybercriminals to access a powerful toolkit without requiring deep technical expertise. The malware is capable of extracting sensitive data from cryptocurrency wallet extensions, web browsers, and various management applications, while also harvesting files directly from compromised systems. Immediate removal is critical upon detection to minimize damage.

Designed for Efficiency, Built for Evasion

Miolab is not a basic stealer; it integrates a centralized control panel and attack management tools that significantly elevate its threat level. This infrastructure allows even low-skilled attackers to execute complex campaigns. Its lightweight and optimized architecture enhances propagation, ensures consistent performance across diverse macOS environments, and helps evade traditional detection mechanisms.

Command-and-Control: Attack Management Simplified

The built-in control panel provides attackers with a structured overview of compromised victims, including geographic data and harvested information. It also includes functionality to reuse stolen Google authentication sessions, enabling unauthorized account access without requiring passwords or bypassing two-factor authentication directly.

Additionally, Miolab supports the deployment of malicious distribution pages and ClickFix-style attack methods. Operators benefit from real-time notifications via Telegram and can automate various stages of their campaigns, increasing operational efficiency and scale.

Browser and Cryptocurrency Data Extraction Capabilities

Miolab aggressively targets browser-stored data, extracting credentials and session-related information that can be leveraged for further compromise. Its reach extends across both mainstream and niche browsers, significantly broadening its impact surface.

• Sensitive browser data collected includes saved passwords, cookies, browsing history, and autofill details such as emails and addresses
• Authentication artifacts such as Google tokens and Safari cookies are also harvested
  Targeted browsers include Chrome, Edge, Firefox, Arc, Brave, Librewolf, Opera, Opera GX, SeaMonkey, Tor Browser, Vivaldi, Waterfox, Yandex, and Coc Coc
• Beyond browsers, Miolab focuses heavily on cryptocurrency assets by extracting files such as .dat, .key, and .keys from over 200 wallet extensions. It also targets applications used to manage hardware wallets, enabling the theft of critical recovery data.
• Targeted crypto tools include Atomic Wallet, Binance, Bitcoin, DashCore, Dogecoin, Electrum, Exodus, Guarda, Litecoin, Monero, Tonkeeper, and Wasabi Wallet
• Applications such as Ledger Live, Ledger Wallet, and Trezor Suite are specifically targeted for 24-word recovery seed phrase extraction

Beyond Browsers: Messaging and Local Data Exploitation

The malware extends its reach into communication and productivity applications. It can hijack active sessions from platforms such as Telegram and Discord, granting attackers account access without credentials. It also inspects Apple Notes, a common location where users may unintentionally store sensitive information such as passwords or cryptocurrency recovery phrases.

Once data collection is complete, Miolab compresses the stolen information into a ZIP archive and exfiltrates it via HTTP. To conceal its activity, it displays a deceptive macOS error message indicating that the application cannot run.

Impact: The Real Cost of Infection

A Miolab infection can lead to severe consequences. Victims may experience financial losses due to stolen cryptocurrency, unauthorized account access, identity theft, reputational harm, and the possibility of further malware infections stemming from the initial compromise.

Infection Chain: Social Engineering at Its Core

Miolab relies heavily on deception to infiltrate systems. Cybercriminals distribute it via fake macOS applications packaged as disk image (.DMG) files, carefully crafted to resemble legitimate software. These installers often feature convincing branding, icons, and user interfaces to increase credibility.

Once executed, the malware initiates a multi-stage infection process. It presents a fake installation interface prompting users to bypass security warnings by right-clicking and selecting 'Open.' It then attempts to terminate the Terminal application to limit visibility into its actions. A counterfeit macOS password prompt is displayed, tricking users into providing their system credentials.

After validating the password, Miolab gathers system-level intelligence, including hardware specifications and software configurations. It proceeds to scan key directories such as Desktop, Documents, and Downloads, targeting files like documents, spreadsheets, PDFs, and password-related data. During this process, users may encounter permission requests, while the malware silently aggregates and prepares the collected data for exfiltration.
