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.
