AmnesiaStealer Gives Attackers Live Control of Victims’ macOS Browsers
Jamf Threat Labs analyzed AmnesiaStealer, a Rust-based macOS infostealer spread via fake GitHub pages that also grants live hidden browser control.
AmnesiaStealer is a three-stage Rust infostealer distributed through counterfeit GitHub download pages using the ClickFix technique, a lure shared with Atomic Stealer and MacSync campaigns. It harvests the keychain, 16 Chromium browsers, Apple Notes, Telegram and documents, reusing a password captured via a fake installer dialog. A third-stage stream module clones the victim's browser profile headlessly and lets operators drive the session via Chrome DevTools Protocol, while persistence uses a LaunchDaemon impersonating Apple's com.apple.ReportCrash.agent. On macOS 26 it may replace Chrome's Safe Storage key, a useful detection signal.
