Malicious Pop-ups Are Still a Scourge
The greatest digital threat to most of us remains the risk of clicking on ads and links that we shouldn’t. Whether it’s ads offering too-good-to-be-true deals or emails warning that your YouTube/Facebook/X account has been disabled, there is always some new clever technique to convince us to click a malicious link. One of the old standbys in the scammer toolkit is the fake iPhone virus warning, so we’ve recently updated our article about what to do if you see a virus warning on your iPhone.
The Bottom Line: These alerts are fake. iPhones can’t be scanned for viruses, so any pop-up warning that a virus has been detected by a scan is lying. For more, see iPhone Virus Warning: How to Get Rid of Fake Apple Security Alerts (2023)
FBI Warning About NFT Scams
Crime in the NFT marketplace remains extremely common. One example of an NFT-related scam that’s been making the rounds lately has been called out in an FBI Warning. Criminals create social media accounts that appear identical to known NFT creators, then use those accounts to announce a surprise deal, “mint” of new NFTs, or a sale—all places where they use the sense of urgency to trick people into acting quickly. When victims connect to purchase, their accounts are instead drained.
The Bottom Line: NFTs are digital artworks, so if you are interested in trading them, be aware of the artist you are purchasing from, follow them directly and not any look-alike accounts, and always double-check who you are interacting with before making a purchase, especially if the purchase is made to feel urgent.
MacOS App NightOwl Is One for the Trash
NightOwl is an older app, and there’s a good chance you aren’t using it. But this case is still interesting to help understand how potentially unwanted behavior can sneak onto your machine. NightOwl is a little third-party Mac app that swaps your color scheme from light mode to dark mode at sunset. You don’t need any such app anymore because the same functionality is built into your Mac’s operating system. However, people don’t always remove old software they’re not using, and that creates an opportunity for malfeasance.
According to a report by Arol Wright at How-To Geek, the developers of NightOwl sold it to a company called TPE.FYI LLC, who then updated the code of NightOwl to do some uncool things. NightOwl now modifies the computer’s network settings to permit the Mac to serve as a gateway for internet traffic from the company’s affiliates. This means that NightOwl will use the computer’s internet bandwidth and processing resources to do tasks for unknown third parties. Uncool, NightOwl. Uncool.
The Bottom Line: If you happen to be running this app, you should remove it completely. More generally, this demonstrates a common method for sneaking malware onto computers: when an app or extension has grown long in the tooth, the developers may abandon that app or sell it to a third party interested in exploiting the computers where it is installed. It’s a good idea to remove old apps and extensions that you’re not using anymore, and for any non-Apple application you run, consider checking in every few years to make sure it’s still actively supported by a trustworthy team.
Researchers Identify Keystrokes on a MacBook from Audio in a Zoom Call with 93% Accuracy
Researchers at several UK universities have collaborated to produce an AI tool that can listen to the sounds of someone typing on a keyboard in order to identify what they are typing with a high degree of accuracy. Tools similar to this have been around since at least the early 2000s, but this research demonstrates how deep learning AI tools can make them much more accurate and effective. Using such a tool, an attacker could analyze the audio of a Zoom call and recreate any passwords entered by the presenter during the call.
The Bottom Line: In general, avoid typing passwords during any Zoom call or other screen sharing or screen recording event. If you need to type, consider muting your microphone while you do so.
Bug in the Screen-Time App Allows Kids to Bypass Controls
The feature called Downtime, which may be found in the Settings app > Screen Time > Downtime, allows parents and guardians to specify hours of the day when a ward’s iPhone is locked and inaccessible. According to a report from the Wall Street Journal, a bug has been causing the schedules set by some users to revert to previous or default settings.
The Bottom Line: If you use Downtime, consider double checking to make sure it’s still set up how you want it.
