Stealthy ModStealer Malware Targets Crypto Wallets on Mac and Windows—Here’s How to Protect Your Assets

Watch out: A new strain of undetectable malware is hunting cryptocurrency wallets across both Mac and Windows systems.

Dubbed ModStealer, this sophisticated threat slips past traditional security defenses—leaving investors exposed to silent, rapid asset theft.

Active verbs only: ModStealer infiltrates, extracts, and vanishes—leaving little trace behind.

How it works: The malware scans for wallet files, private keys, and seed phrases—then exfiltrates data to remote servers. No triggers, no alerts.

Why it matters: As crypto adoption grows, so do attack surfaces. Even hardware wallets aren’t immune if connected to compromised devices.

Protect yourself: Use cold storage, enable 2FA, avoid suspicious downloads—and maybe don’t keep your life savings on a laptop that also runs questionable gaming mods.

Final thought: In the wild west of digital finance, sometimes the biggest risk isn’t market volatility—it’s forgetting to update your antivirus.

New threats targeting Mac and Windows crypto users

As crypto adoption is on the rise all across the globe, threat actors have increasingly focused on devising complex attack vectors to siphon digital assets. ModStealer is far from the only threat making headlines.

Earlier this month, researchers at ReversingLabs rang the warning bell regarding an open-source malware embedded within ethereum smart contracts that could deploy malicious payloads targeting crypto users.
