By making contact and attempting to comply with the ransom demands, you mark yourself as vulnerable and are more likely to be targeted in the future. It’s very important that if you receive a ransomware threat that you don’t panic and that you think twice before contacting the sender. For example, the recent macOS attack, KeRanger, demanded that users paid one Bitcoin for their data to be recovered.

If the victim agrees to pay the hijackers, they receive a special code to unlock their data. Ransomware encrypts all data on victim’s computer making it unusable.

However, they are often spotted by ‘white hat’ hackers who alert the software vendor to give them time to fix it before they go public with it. They are surprisingly common, even in code as robust as iOS and macOS. Backdoors are often exploited by hackers in order to access data or place files on a computer or mobile device. BackdoorĪ backdoor is a vulnerability in a piece of code that allows unauthorised access to a system. Keyloggers are relatively rare compared with some other types of malware, but the damage they can do is huge. The idea is that it will record you typing usernames and passwords and so the hacker will have your log in details that they can then use to hack your account. Once installed, it records keystrokes you type and sends them back to the hacker’s server. KeyloggerĪ keylogger is a type of spyware. You can read more about the new security features in MacOS Catalina at the end of this guide. macOS Catalina includes a couple of new features to make it more difficult for third-party apps to spy on you, including notifying you when any app tries to take a screenshot or log keystrokes. That could be done by taking photos with a webcam, or intercepting information you type into a website. The term spyware covers a number of different types of malicious code, but they all have one thing in common – they try to gather sensitive data. If you come across a site that does that, treat it as a red flag and don’t download anything. On the Mac, bloatware is most likely to come from sites that offer software downloads and insist you use their proprietary download manager to download it. Here’s a rundown of the different types of malware that can find their way onto your Mac. Types of malware threats you can encounter on macOS That’s just one example of how vulnerabilities in the OS can be exploited, there have been many others. If the user then accesses the network share, unzips a file and clicks a link, they could run malicious code without realising. The vulnerability the researcher, Filippo Cavallarin discovered and then described on his blog, exploited the fact that you only have to give permission once, and that when the app is installed, it can run freely.

To install anything else, you have to give it explicit permission. Depending on how you set Gatekeeper, it will either only allow apps from the Mac App Store to be installed without user intervention, or apps from the App Store along with those that have been code-signed by their developers. The vulnerability in question was in Gatekeeper, the tool that prevents unauthorised apps from being installed on your Mac. One recent example occurred in May 2019 when a researcher, having had no response after giving Apple 90 days to fix it, went public with details of a vulnerability he had discovered.
