Hope 2020 will get a legitimate MAC OS App. They take the time to get the app cleared by the Apple iOS App Store but cannot be bothered to get it compatible with the MAC OS App Store. I shouldn't have to quarantine the Ring Central App on Mac OS.Zoom made it so that when you clicked a Zoom link and had the client installed, the link automatically opened the Zoom client. #1577: iPhone 12/12 Pro repair program, fix corrupted Chrome extensions, iCloud Mail custom domains, Chipolo AirTag alternative, 10-digit dialing changesRecently, software engineer Jonathan Leitschuh uncovered a major security flaw in the Mac client for Zoom, a video conferencing system popular with businesses, and RingCentral, which is a rebadged version of Zoom. #1578: Apple delays CSAM detection, upgrade Quicken 2007 to Quicken Deluxe, App Store settlement and regulatory changes Apple lawsuit decided, Internet privacy limitations, combine Mac speakers #1579: Apple “California Streaming” event, OS security updates, Epic Games v.The update installs automatically without any interaction on your part. The company has promised additional updates to improve user privacy.To make sure that users who neglect to update the Zoom app are not exposed, Apple released a silent macOS update that removes the hidden Web server. (Note that it cannot disable the green LED indicator of the FaceTime cameras in the Mac, so if you use that camera exclusively, you always know when it’s on.)Even worse, you couldn’t eliminate the vulnerability by merely deleting the Zoom app, because Zoom installed a hidden Web server on your Mac that would reinstall the Zoom client for you if necessary when you clicked a Zoom link.Initially, Zoom defended its use of the hidden Web server, but quickly repented, and released an update, version 4.4.4 (53932.0709), that removes the hidden Web server and offers an option to completely uninstall Zoom.
How to Tell If You’re AffectedTo test for the vulnerability for yourself, the easiest way is to click one of the links below, which Leitschuh set up as proofs of concept. Even after the server is uninstalled, it’s possible for a Mac to inadvertently join a Zoom conference with the Web cam enabled. (Hat tip to Howard Oakley for this tidbit.)Reader Al Varnell has told us that Apple’s update did not remove the RingCentral Web server, so you’ll have to update its client to the latest version to get rid of it.Unfortunately, the hidden Web server was only part of the vulnerability. Click the Install Date column header so that you see the latest installations first, and look for MRTConfigData, which should be at version 1.45 or above. Ringcentral How To Avoid That(This doesn’t affect Safari.)But if you don’t want to fool with these settings, it’s easier to uninstall Zoom entirely (and we wouldn’t blame you if you did). You can disable that by opening Zoom, going to zoom.us > Preferences > General and unchecking “Add Zoom to macOS menu bar.”To prevent Zoom from activating your Web cam without your explicit consent, open Zoom and choose zoom.us > Preferences (Command-,), click Video in the Settings window’s sidebar, and check the “Turn off my video when joining a meeting” option.If you use Chrome or Firefox as your browser, you’ll also want to check and change some settings to prevent Zoom links from opening automatically, per Karan Lyson on GitHub, because it’s possible that you gave Zoom permission to open Zoom conferences automatically when you click a Zoom link. If the app prompts you, click Update Now to update it.Note that version 4.4.4 (53932.0709) adds a Zoom icon to your menu bar. Here is how to avoid that.First, check if you have the latest version of the client by opening Zoom and choosing zoom.us > Check for Updates. Be warned that if the vulnerability is present clicking either link will drop you into a video conference, likely with other people as freaked out as you are.The Apple update takes care of the hidden Web server, but you can still be tricked into clicking a Zoom link that activates your Web cam.

Open your user library folder in the Finder by holding Option, choosing Go in the menu bar, and choosing Library. Quit Chrome by choosing Chrome > Quit Google Chrome. Google chrome for mac downloadDon’t take my word for it: you can check yourself by opening Terminal, entering the following command, and pressing Return:That command searches for services listening on port 19421, which is the port that both Zoom and RingCentral used. I’ve tested and confirmed this on my machine by deleting the hidden ~/.zoom file I made in Terminal and reinstalling Zoom, which didn’t recreate the directory that older versions kept the Web server in (see my description of the old Terminal method below if you don’t know what I’m talking about). If these preferences are found, change them to “Always ask.”As for the Web server that Zoom snuck onto Macs, between Apple’s update and the Zoom update, it should be eliminated. Click in the Find in Preferences field. Choose File > Save, close TextEdit, and re-open Chrome. You no longer need to do any of this to fix Zoom, but I’m leaving it here both for historical reference and because this is a handy technique to be aware of in case another app pulls a stunt like this.First, open Terminal and enter kill -9 PID, with PID (process identification number) being the PID that you saw when you ran lsof -i :19421. The Old Terminal MethodBefore the Apple update and Zoom’s 4.4.4 (53932.0709) update, you had to use Terminal wizardry to disable the hidden Web server. Under older versions of Zoom, you’d see an entry called ZoomOpene like in the screenshot below.You can also enter ls ~/.zoom, which should return with “No such file or directory” after updating to version 4.4.4 (53932.0709). And with Zoom already showing incredibly poor judgment, we advise uninstalling the client unless you absolutely need it.Since I read your article, I’ve been checking the System Information app’s “Installations” list, but the “MRTConfigData” item still says “1.28, 7, 15:59.”This morning (Japan time) I installed Security Update 2019-004 into my iMac’s High Sierra 10.3.6, but System Information still says the same thing about MRTConfigData.I searched for files that has the text string “METConfigData” in the name, and EasyFind found two files named com.apple.pkg.MRTConfigData…, one ending with".plist", and another ending with “. But what’s less assuring is that there may be other security and privacy issues lurking beneath the surface, waiting to be discovered.
