Advisory Alert

Atomic macOS Stealer malware infection

A data-stealing threat aimed at Apple Mac computers is being used to quietly collect saved passwords, financial details, and other personal information. People can be exposed through fake software downloads, harmful links, or pop-ups that trick them into installing something they did not intend to trust.


Who is at risk

Mac users are most at risk, especially anyone who downloads apps from unofficial websites, clicks unexpected links, or enters their computer password after a suspicious prompt.

What to watch for

Watch for unexpected password prompts, new apps you did not install, browser changes, unusual account logins, or missing money or messages sent from your accounts that you did not authorize.

What to do

Only install apps from trusted official sources, remove anything recently downloaded that seems suspicious, change important passwords from a different trusted device, and turn on extra login protection where available.
