Jul 16, 2019By Shaina Raskin

A snapshot of last week’s reported cybersecurity breaches and vulnerabilities


A security researcher publicly disclosed a zero-day flaw that enables websites to hijack cameras on Apple Macs that have the Zoom video-conferencing app installed. The researcher initially disclosed the vulnerability to Zoom, giving them 90 days to solve the problem; it didn’t, so he went public. The company now says it has fixed the vulnerability; the researcher disagrees. To read more:

Apple also released an update for Mac users to remove the vulnerability in Zoom. Apple’s update will apparently protect past and present users from the app itself. To read more:

Android apps

Researchers at the International Computer Science Institute in California found that some app developers are using questionable techniques for harvesting user data. They discovered that more than 1,300 Android apps use workarounds to collect precise location data even when users have explicitly denied the required permissions. To read more:

Astaroth malware

Microsoft’s security team is warning users of an ongoing malware campaign to distribute the Astaroth trojan. The campaign consists of a massive spam operation that sends out email with a link to a website hosting an LNK file. If run, the file launches the Windows Management Instrumentation Command-line tool, which starts a chain of events that eventually loads the Astaroth malware. To read more:

Victims received spear-phishing emails that contained a link to apparently official websites; these faked sites had the ability to infect users’ machines with malware. To read more:

Torrent sites
