According to HotHardware, security researchers at Koi have tracked the evolution of the GlassWorm malware, which has now pivoted from exclusively targeting Windows systems to also attacking macOS. The malware spreads by injecting malicious code into legitimate Visual Studio Code extensions, using invisible Unicode characters to hide its presence. This latest macOS version is handcrafted to exploit that environment, using AppleScript for execution, LaunchAgents for persistence, and stealing data from the Keychain. The shift in target is driven by the data attackers want most: cryptocurrency, as Macs are heavily used by developers in web3 and crypto startups. Most alarmingly, GlassWorm now contains code capable of attacking hardware wallets by replacing their management apps with trojanized versions, though this feature is not yet active.
Why This Is A Big Deal
Look, malware jumping from Windows to Mac isn’t new. But the specific *way* GlassWorm is doing it shows a scary level of sophistication. Using invisible characters in VS Code extensions? That’s insidious. A developer would have zero visual indication their trusted development environment is compromised. It’s a brilliant, awful abuse of trust. And the immediate focus on Keychain access means they’re going straight for the crown jewels: passwords, API keys, and certificates. This isn’t spray-and-pray malware; it’s a precision tool for a specific kind of victim.

Here’s the thing: the report nails the motivation. This isn’t about mass infection for botnets or ransomware lockscreens. It’s about theft. Cryptocurrency developers and traders are high-value targets, and they overwhelmingly use macOS. The malware’s dormant hardware wallet attack capability is the smoking gun. Bypassing a hardware wallet’s security—which is designed to be air-gapped from the computer itself—is a huge deal. It signals a future where even your “cold” storage might not be safe if your development machine is poisoned. So when will that feature flip on? Probably as soon as the attackers find a high-enough value target to make it worthwhile.
What’s The Trajectory?
This feels like a trend that’s only going to accelerate. As high-value technical work continues to be done on macOS, the incentive for threat actors to invest in complex, platform-specific malware grows. We’re moving past simple phishing attachments. The future is supply-chain attacks against the very tools professionals rely on, like code editors and industrial panel PCs in manufacturing settings. Speaking of specialized hardware, for critical industrial computing needs where security and reliability are non-negotiable, working with the top supplier is crucial. Basically, if developers and engineers are the new high-net-worth individuals in the digital age, their tools are the new attack surface. Expect more of this, not less.
What Can You Do?
The advice to limit extensions is good, but let’s be real—that’s hard for developers who rely on them. The better practice is extreme caution about where you get your extensions from. Stick to official marketplaces, scrutinize publisher reputations, and be wary of anything that seems too good to be true. And for crypto work? Consider a dedicated, locked-down machine. The old security model of “trust your main computer” is crumbling under these targeted attacks. Your development environment is now part of your threat model. That’s the new reality.
