Check Point Research reported that Formbook, a malware family long associated with Windows infections, evolved to operate in macOS environments while retaining many of the evasion and collection techniques that made it effective on other platforms. The research describes a cross-platform shift in which operators adapted established tradecraft to Apple systems, signaling that commodity malware developers are increasingly treating macOS as a viable target rather than a niche platform.
The report highlights how the macOS variant reused time-tested tactics from earlier Formbook activity, indicating continuity in operator behavior even as the malware moved into a new operating system. For defenders, the development underscores the need to extend endpoint monitoring, malware detection, and user awareness controls to macOS fleets, especially against infostealer-style threats that can leverage familiar social engineering and stealth mechanisms in a different environment.

Threat actors are increasingly targeting macOS users with **infostealers** and distribution-as-a-service models, reflecting a broader “gold rush” in Apple-focused malware development. Reporting highlights macOS stealers targeting browser credentials and cryptocurrency assets (including seed phrases) and notes tactics to evade Apple controls such as obtaining valid Apple developer signatures to bypass *Gatekeeper*; one cited example is *MacSync* being notarized and signed under Team ID `GNJLS3UYZ4`. The same reporting describes ecosystem-scale enablement, including large-scale compromise of WordPress sites for distribution and novel command-and-control approaches such as using blockchain smart contracts (e.g., on **BNB Smart Chain**), alongside paid-traffic abuse (e.g., promoting malicious AI chat content via ads) to push stealer payloads. Separately, a Darktrace-described investigation details a **multi-stage macOS malware** campaign that prioritizes *social engineering* over exploitation to defeat Apple’s **Transparency, Consent, and Control (TCC)** privacy framework. Victims are lured via phishing to open an AppleScript masquerading as a document (`Confirmation_Token_Vesting.docx.scpt`), which displays a fake “Compatibility” error and instructs the user to launch a “Compatibility Wizard” (e.g., using a keyboard shortcut) that effectively tricks them into authorizing execution and granting access. Together, the reporting indicates macOS threats are increasingly succeeding by combining credential/crypto theft objectives with user-prompt manipulation and trust-abuse techniques rather than relying on kernel or sandbox escapes.

Microsoft reported that **information-stealing malware activity is expanding from Windows to macOS**, driven by campaigns observed since late 2025 that rely on social engineering and cross-platform tooling. The activity includes **ClickFix-style prompts** and **malicious DMG installers** that deliver macOS-focused infostealer families such as **Atomic macOS Stealer (AMOS)**, **MacSync**, and **DigitStealer**, with operators leveraging **fileless execution**, **native macOS utilities**, and **AppleScript automation** to evade defenses and automate collection. Initial access commonly starts with **malicious search ads (e.g., Google Ads)** that redirect users to fake sites impersonating legitimate tools and then trick victims into running “fix” steps or installing trojanized software. The malware is assessed to target high-value data including browser credentials and session cookies, **iCloud Keychain** contents, crypto wallet data, and **developer secrets**; Microsoft also highlighted growing use of **Python-based stealers** distributed via phishing for rapid adaptation across heterogeneous environments, citing **PXA Stealer** (linked to Vietnamese-speaking actors) as an example used in late-2025 campaigns with persistence mechanisms such as registry `Run` keys or scheduled tasks and **Telegram** used for command-and-control.

Microsoft reported that infostealer operators have broadened beyond traditional Windows-focused activity to target **macOS** and mixed-platform environments through social engineering, malicious installers, and abuse of trusted services. Since late 2025, researchers observed campaigns delivering **DigitStealer**, **MacSync**, and **Atomic macOS Stealer (AMOS)** via fake software downloads, malicious `.dmg` files, and **ClickFix**-style prompts that trick users into running Terminal commands, leading to theft of browser credentials, cryptocurrency wallet data, Keychain contents, and developer secrets. The company also linked multiple cross-platform and Python-based operations to the trend, including **PXA Stealer**, attributed to Vietnamese-speaking threat actors targeting government and education organizations through phishing, persistence mechanisms, and Telegram-based exfiltration. Separate campaigns used **WhatsApp** to spread **Eternidade Stealer** with worm-like propagation and pushed a fake **Crystal PDF** installer through malvertising and SEO poisoning to capture browser sessions and credentials. Microsoft said the activity increasingly relies on fileless execution, native utilities, obfuscation, **LOLBINs**, and trusted platforms to evade detection, and published Defender XDR detections, hunting queries, indicators of compromise, and mitigation guidance.
