MacStealer Malware Steals Apple User Data and Passwords

MacStealer malware can attack Macs running macOS Catalina or later, with either Intel or Apple M-series chips. It can get passwords, cookies, and credit card data from Firefox, Google Chrome, and Microsoft Brave browsers, and extract several different file types, including .txt, .doc, .jpg, and .zip, and it can extract the KeyChain database. MacStealer appears to propagate through a “weed.dmg” executable file. It’s unclear if MacStealer has been logged in the CVE.report database that tracks vulnerabilities and exposures, and Apple has not commented on the malware.
