A new strain of malware purpose-built to steal crypto wallet data is slipping past every major antivirus engine, according to Apple device security firm Mosyle.<\/p>\n

Dubbed ModStealer, the infostealer has been live for nearly a month without detection by virus scanners. Mosyle researchers say the malware is being distributed through malicious recruiter ads targeting developers and uses a heavily obfuscated NodeJS script to bypass signature-based defenses.<\/p>\n

That means the malware\u2019s code has been scrambled and layered with tricks that make it unreadable to signature-based antivirus tools. Since these defenses rely on spotting recognizable code \u201cpatterns,\u201d the obfuscation hides them, allowing the script to execute without detection.<\/p>\n

In practice, this lets attackers slip malicious instructions into a system while bypassing traditional security scans that would usually catch simpler, unaltered code.<\/p>\n

Unlike most Mac-focused malware, ModStealer is cross-platform, hitting Windows and Linux environments as well. Its primary mission is that of data exfiltration, and the code is presumed to include pre-loaded instructions to target 56 browser wallet extensions designed to extract private keys, credentials, and certificates.<\/p>\n

The malware also supports clipboard hijacking, screen capture, and remote code execution, giving attackers the ability to seize near-total control of infected devices. On macOS, persistence is achieved via Apple\u2019s launching tool, embedding itself as a LaunchAgent.<\/p>\n

Mosyle states that the build aligns with the profile of \u201cMalware-as-a-Service,\u201d where developers sell ready-made tools to affiliates with limited technical expertise. The model has driven a surge in infostealers this year, with Jamf reporting a 28% rise in 2025 alone.<\/p>\n

The discovery comes on the heels of recent npm-focused attacks where malicious packages like colortoolsv2 and mimelib2 used Ethereum smart contracts to conceal second-stage malware. In both cases, attackers leveraged obfuscation and trusted developer infrastructure to bypass detection.<\/p>\n

ModStealer extends this pattern beyond package repositories, showing how cybercriminals are escalating their techniques across ecosystems to compromise developer environments and directly target crypto wallets.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
