PamStealer: Rust-based macOS infostealer that validates credentials through PAM

- PamStealer is newly discovered macOS malware written in Rust. It's an "infostealer" — it steals passwords, credentials, and files from infected Macs. - Its key novelty: it validates stolen passwords using PAM (Pluggable Authentication Modules), macOS's low-level authentication system. This lets the malware check that a password is actually correct before stealing it, avoiding dead or fake credentials that might tip off security tools. - The report comes from Jamf, a major Apple-focused enterprise security firm whose threat research team regularly discovers new macOS malware. The audience is IT admins and security pros managing Mac fleets. - macOS infostealers are growing more common as Apple's business market share rises. Recent examples include Atomic Stealer and MacStealer. Rust is also a growing trend in malware — it's harder to reverse-engineer and more portable across platforms.
