Well-healed Apple Mac users have been targeted by a wave of malware that causes popups and fake support alerts, perpetrated via a denial of service (DoS) attack method.
« A newly registered scam website targeting Mac users was making the rounds late last year. Simply visiting the malicious site on an older version of macOS would start creating a series of email drafts, which eventually cause the machine to run out of memory and freeze, » said, MalwareByte’s Jerome Segura.
Sequra has covered the threat on his employers’ blog. He said that the attack can be triggered when a user visits a compromised web page. This makes avoiding infection difficult, depending on how carefully the user surfs the internet.
« The malicious webpage will first determine the version of OS X via a user agent check, and push two different versions of the denial-of-service.
