Ransomware is far less common in the macOS environment than threats like adware and scareware, and yet such detrimental cybercriminal campaigns are exploding once in a while. EvilQuest, the latest Mac ransomware spreading through contagious pirated apps, stands out from the rest. In addition to encrypting a victim’s files, it pilfers some of them. What’s worse, the attackers appear to provide no viable way of decrypting the data even if the ransom is paid.

Macs are made inherently flexible when it comes to performance, and there is usually no need to opt for anything third-party – ideally, the operating system copes with the task autonomously. If there are processes that siphon off too much memory, macOS identifies the hogs and triggers kernel_task process that performs the intelligent balancing. But what if this routine goes wrong and said entity is constantly eating up the CPU? Read more to find out.

Mac owners are generally on the safe side when it comes to avoiding severe threats such as ransomware, but Apple computers are being heavily targeted by adware. These apps are trivial in terms of the damage being caused, but the nuisance facet of their impact is tremendous. LinkBranch is an example of relatively low-risk malware that diminishes its victims’ online experience by showing ads and rerouting the browser to unwanted sites.

Whereas using a VPN used to be an exotic prerogative of privacy addicts, it has turned into a normal habit that keeps all things Internet secured from undesirable tampering. It comes as no surprise that the Global Protect VPN app for Mac is gaining traction, especially in business circles. However, this tool is known to have been exposed to several exploitation scenarios in the not-so-distant past, so some users may want to get rid of it.

Browser preferences are among the fundamentals of regular computer use, being nifty shortcuts to personalize one’s Internet experience. This convenience works flawlessly until a piece of malware shows up. The category of harmful code called adware is the one to blame for tweaking victims’ web navigation defaults, as is the case with the Yahoo redirect virus on Mac. This article explains the mechanics of said attack vector.

Counterintuitively, the landscape of Mac threats isn’t dominated by severe-impact predators such as ransomware. Instead, it’s populated most densely by applications that cause little harm but prevent users from surfing the web like they routinely do. Viruses such as UtilityParze / UtilityParse typify this category as they focus on diminishing the Internet experience without significantly extending their reach to other areas of macOS.
