Have you ever used your computer in the middle of the night or in a dark room and felt blinded by the brightness of your screen? That’s not only unpleasant but also potentially bad for your eyes. That’s why many people prefer to use night mode, a feature that adjusts the temperature and contrast on your Mac to make it easier on your eyes.
NightOwl took a dark turn
But before night mode was available, Mac users relied on the app NightOwl to switch between light and dark mode depending on the time of day. However, NightOwl took a dark turn and has become a serious security threat.
How NightOwl became a problem for Mac users
NightOwl was once a useful app that helped Mac users adjust their screen modes according to the time of day. However, in November 2022, the original developer of NightOwl, Benjamin Kramser, sold the app to a company called TPE.FYI LLC, and has accused the new owner of turning the app into a malware delivery vehicle.
Kramser has posted on his developer site that the NightOwl app under new ownership “has opted to monetize the app by integrating a third-party SDK. This decision is not affiliated with me in any way, and I do not endorse it in any form.”
Although the NightOwl has said the allegations are inaccurate and false, we have not heard back from TPE.FYI LLC after reaching out for additional comment. Apple has since reportedly revoked the app’s signing certificate.
Unwanted traffic: could send and receive internet data that was not meant for you. This is like having strangers use your home address for their online activities without your knowledge. This could use up your internet speed and make your connection slower.
If you already downloaded the NightOwl app on your Mac, you should uninstall it as soon as possible to avoid any potential security risks. Here are some steps you can follow to remove the app and its associated files.
- Close the NightOwl app on your Mac. You can right-click on the app icon on the Dock and select Quit.
- Open the Finder and click on Applications on the left panel. Find and locate NightOwl in the list of programs.
- Drag the NightOwl app icon to the Trash and release it. Alternatively, you can right-click on the app icon and select Move to Trash.
- Right-click on the Trash icon on the Dock and select Empty Trash. This will delete the app from your Mac but not its related files.
- To delete the related files, you need to access the hidden Library folder on your Mac. To do this, Click on Go on the top menu bar and select Go To Folder. Type ~/Library/ in the box and hit Enter.
- In the Library folder, look for the following subfolders, Application Support, Caches, and Preferences. Open each of these subfolders and delete any files or folders that have NightOwl.
- After deleting all the related files, you can close the Library folders and empty the Trash again.
To make sure that your Mac is free of any malware that might have been installed by NightOwl, you should scan your Mac with reliable antivirus software. Having good antivirus software actively running on your devices will alert you of any malware in your system,
Trust but verify: While it’s tempting to download that flashy new app everyone’s talking about, remember to exercise caution. Before any installation:
App Store = Safe haven: Apple’s Mac App Store is curated, meaning apps go through checks:
Have strong passwords and use 2-factor authentication: Using the same password across multiple platforms will always make you more vulnerable because if one account gets hacked, they all get hacked. Plus, be sure to activate 2-factor authentication as an extra shield that will prevent a hacker from getting into your accounts. Finally, make sure to use a password manager to keep track of all your passwords.
There seems to be an app for everything, making life so much easier. However, by following these simple steps, you can avoid welcoming a malicious app disguised as a trojan horse onto your device.
