You’re not going to love this, but a group of security designers have apparently discovered that a new way of attacking the macOS with malware is being used.
The researchers have noted that malicious online advertising found to have used steganography to disguise its payload within an ad’s image files, in order to fool security systems.
Analyzed by Confiant and Malwarebytes, an attempt to infect Macs from January 11 until January 13 was performed by a “malvertizer” dubbed “VeryMal” by the firms. It is believed that the attempted attack ad was viewed on as many as 5 million Macs during the brief period of time it was active.
