AmnesiaStealer is a multi-stage, Rust-based information stealer targeting macOS. Identified by Jamf Threat Labs in August 2026, it is distributed through counterfeit GitHub software-download pages using ClickFix social engineering. Victims are persuaded to paste an encoded command into Terminal, initiating a shell-script dropper that downloads, extracts, removes quarantine attributes from, and launches the malware before deleting installation artifacts.
The primary payload profiles the infected Mac and presents an Installer-themed native password prompt. It validates the supplied login password locally and reuses it for privileged operations and keychain access. It collects macOS keychain material, Apple Notes, Telegram sessions, documents, cryptocurrency-wallet artifacts, and browser data, including credentials, cookies, history, bookmarks, and extension data from sixteen Chromium-family browsers. Collected material is archived and exfiltrated to attacker-controlled infrastructure. Persistence is established through a root LaunchDaemon masquerading as an Apple crash-reporting component. A configurable cryptocurrency clipboard-hijacking module is also present, although it was disabled in the analyzed build.
An on-demand Rust browser-streaming component clones browser profiles and launches concealed headless instances of seven Chromium-family browsers. Using the Chrome DevTools Protocol and WebSocket relay channels, operators can receive live screencasts, navigate websites, manage tabs, send keyboard and mouse input, and export or import decrypted cookies. This enables abuse of still-valid authenticated sessions without changing the victim's visible browser window. Injected scripts reduce signs of browser automation.
AmnesiaStealer uses encrypted, builder-generated configurations and macOS-version-specific execution logic. It attempts older privacy-control bypasses, including techniques derived from CVE-2020-9771, whose effectiveness is restricted by subsequent Apple security changes. On macOS 26, failed browser-key recovery can trigger destructive replacement of Chrome Safe Storage keychain material, preventing decryption of previously saved secrets. Its backend is called Amnesia Panel; no specific threat-actor attribution is established.

That command downloads and starts a multi-stage Rust-based payload while removing installation traces.
Operators can see what appears in the browser and send keyboard or mouse input back to it.
Instead of sorting through exported data later, an attacker can act while a session is valid, including viewing account pages, moving through sign-in flows, exporting decrypted cookies, or importing cookies into another session.
the malware gathers credentials, browser records, Apple Notes, Telegram session data, documents, wallet-related browser data, and keychain material. | It also tries to obtain each browser’s Safe Storage key from the login keychain, potentially helping the later module read protected browser information.
Stage one targets sixteen Chromium-family browsers, collecting cookies, login databases, history, bookmarks, extensions, Local State, Preferences, and related artifacts.
Operators can see what appears in the browser and send keyboard or mouse input back to it.
It also spawns a relay channel using WebSocket to accept operator commands and report the status back to the same endpoint. | It includes the following details - Command-and-control (C2) endpoints (i.e., "debug.allllowef[.]space/send/")

A newly identified macOS information stealer delivered via ClickFix social engineering. It steals credentials, browser data, Apple Notes, Telegram session data, documents, wallet-related browser data, and keychain material, and includes a second-stage module that clones a victim browser profile into a hidden headless Chromium session for real-time abuse of authenticated sessions. It also establishes persistence via a disguised LaunchDaemon.
