McAfee Labs Threats Report: September 2017 said healthcare accounts for 26 percent of Q2 2017 security incidents.
Healthcare surpassed public sector to report the greatest number of security incidents in Q2, while the Faceliker Trojan helped drive quarter’s 67 percent increase in new malware samples from the social media landscape.
Facebook emerged as a notable attack vector, with Faceliker accounting for 8.9 percent of 52 million newly detected malware samples. Trojan infects a user’s browser when she visits malicious or compromised websites. It then hijacks her Facebook “likes” and promotes the content without her knowledge or permission.

# Global infections of mobile devices rose 8 percent, led by Asia with 18 percent
# Mac OS malware growth declined to 4 percent as adware surge subsides
