Apple OS X devices have seen a considerable increase in malware attacks throughout 2019. In the past, Mac computers have been targeted by considerably fewer cyberthreats as their rivals, Android and Windows. This difference, possibly due to a lower overall user base, has eroded as of late. Cyber threat is an umbrella term used to describe anything digital that may seek to infect a device and do all manner of nasty things. A majority of infections are caused by interacting with suspicious ads or pop-ups, though they can be transferred through physical data transfer, like USBs.
Recently, Malwarebytes released a report noting the rise in detected infections on OS X devices. Across the main three platforms of Windows PCs, Android and Mac OSX that Malwarebytes tested, 16 percent of the total detections were found on Mac computers. However, their test was run only on devices that already had their software installed, introducing a considerable amount of bias. However, this year Mac targeted malware such as Newtab made record appearances on their lists.
Nowadays, most devices come installed with some sort of virus protection. For instance, every Windows device comes with a free version of Windows Defender, and sometimes with a trial copy of some branded virus protection. It’s not uncommon for people to use the existence of these as an excuse to not seek out better protection. These programs only provide the bare minimum in terms of protection, and often can miss malware that is downloaded via user interaction. Mac OS X devices, on the other hand, do not come stock with clearly labeled anti-virus and anti-malware software.
Mac Adware To Watch For
Newtab is among the most prominent Mac-targeting adware to watch out for. Often users download Newtab while it’s disguised as another application or installed along with other viruses. It will alter the content of sites and add unwanted browser extensions. The software will do its best to disguise its presence. Oftentimes adware lies to users about problems that their system doesn’t have, compelling them to download damaging software or to buy products and services that they don't need.
There are some telltale signs that a device has been infected with adware, like links not leading to where they’re supposed to, slow browser speed and the appearance of new, suspicious browser toolbars and plugins. In the event that these programs have been found, take the time to back up important files and download reputable adware removal software. The most frequent way for adware to get onto systems is through user interaction, so it's important to stay up to date and suspicious of any odd links or advertisements.
