Skype 8.11.0.4 For Mac카테고리 없음 2020. 2. 7. 09:14
I’m on Mac and have been running version 8.25.0.5 for about two or three weeks now. Skype is showing no updates available. Thanks for all the comments here, guys. Skype (com.skype.skype) is a Mac software application that has been discovered and submitted by users of Aploader. The latest version that our users have reported running on their systems is Skype 7.52.0.597.The most popular version of this application used by our users is Skype 7.33.0.206.
Trustwave recently reported a locally exploitable issue in the Skype Desktop API Mac OS-X which provides an API to local programs/plugins executing on the local machine. The API is formally known as the Desktop API (previously known as the Skype Public API – Application Programming Interface) and it enables third-party applications to communicate with Skype. As described in, the issue is an authentication by-pass discovered in the API whereby a local program could by-pass authentication if they identified themselves as the program responsible for interfacing with the Desktop API on behalf of the Skype Dashboard widget program. An interesting possibility is that this bug is the result of a backdoor entered into the Desktop API to permit a particular program written by the vendor to access the Desktop API without user interaction. Indeed, this possibility seems even more likely when you consider that the Desktop API provides for an undocumented client name identifier (namely 'Skype Dashbd Wdgt Plugin').
Notifying the user of Desktop API through the backdoor works differently than the normal course of action which is to notify the user of an access attempt and prompt the user for permission. In the case of the backdoor no such notification attempt is made and as such the user is not given the opportunity to deny access. Furthermore, no mention is made in the 'Manage API Clients' list.
This allows any program accessing the Desktop API through the backdoor to remain hidden from the user. Finally, no attempts are made to determine what programs that are accessing the Desktop API since they identify themselves as the undocumented client name identifier 'Skype Dashbd Wdgt Plugin'. This opens up the potential for abuse by third-party programs, including malware, running locally on the machine. An unused backdoor? Curiously, the actual Skype Dashboard widget does not seem to utilize the backdoor into the Skype Desktop API despite the name 'Skype Dashbd Wdgt Plugin'. This raises the possibility that the backdoor is the result of a development accident which left the code behind accidentally during the process of implementing the Dashboard plugin.
If it was a coding accident, it is an old one. Our investigations have shown that the string 'Skype Dashbd Wdgt Plugin' has been present in versions of Skype for Mac OS-X for some 5+ years. Discontinued, but not forgotten The Desktop API is being discontinued and gradually phased out of the Skype application across all platforms. However, the original Desktop API was text based and documentation can still be found thanks to.
What can you access? The Desktop API, in previous versions, permitted access to nearly everything that Skype can offer.
This included, but was not limited to: notifications of incoming messages (and their contents), modifying messages and creating chat sessions, ability to log and record Skype call audio to disk and retrieve user contacts. In later versions of the Desktop API, access to text messages was dropped from the specification but access to other features remained. How easy is the backdoor to use? Accessing the backdoor is as easy as changing a single line of code in the numerous examples given by Skype themselves in how to use the Desktop API. A simple change to the 'clientApplicationName' NSString method (or CFString member variable if using the Carbon API), setting this value to 'Skype Dashbd Wdgt Plugin' is all that is required. The technical bit Discovering the backdoor is a relatively trivial process, in fact this can be done with a simple call to the GNU utility 'strings', for instance: You can obtain a source disassembly of the responsible function by utilizing Hopper to disassemble the Skype application binary, the results are shown below: In the above image you can see that the member function 'authLevelForApplication:(NSString.)applicationName' of the object 'SkypeAPIController' returns 1 ('YES') if the value of 'applicationName' is equal to 'Skype Dashbd Wdgt Plugin'. Versions of Skype prior to the Microsoft acquistion utilized one form or another of binary obfuscation/encryption where the binary dynamically unpacked itself upon execution.
This is a typical technique to hamper efforts to extract information and reverse engineer the program. However, in general these techniques were trivial to by-pass by simply attaching a debugger and dumping the pages of memory containing executable code.
Skype 8.11.0.4 For Mac Os X
What does that mean? I have Skype v8.10.0.4 which it claims to be the latest version and it works fine on High Sierra.I have essentially the same problem, I think. Since Mac OS update to 10.13.1, I can’t launch Skype successfully - I just get the Skype application menu with one option, “Quit” and no Skype window. I’ve followed their Support tip of changing my Mac’s language setting and I’ve also tried uninstalling and reinstalling Skype (latest package 8.11.0.4).
Neither of these has made the slightest difference. As a short-term work-around, I tried the beta web version; the interface on that seems functional but I cannot make or receive calls. All very strange! As a last resort you may want to try deleting the preferences that Skype stores on your Mac, but this may not make a difference. Open the Terminal from Spotlight search or via the Launchpad and run the following command (close Skype first): rm /Library/Preferences/com.skype.skype.plist && rm -Rf /Library/Application Support/Skype Please note this will perform a permanent deletion which cannot be reversed and you will lose all your Skype settings, customisations and local chat history. You'll need to login to Skype again afterwards. Once you've run the command, log out of your Mac user account and log back in and try opening Skype again.

If this doesn't work, another application must be conflicting with Skype. Try running the application with nothing else open - once you've closed all the apps displayed on the Dock, make sure no utility apps are running in the system menu bar at the top-right of the screen.As it happens, I didn’t need too resort to that but thanks anyway. The ‘easy’ fix, provided by Microsoft, was to download classic Skype using the installer link: All is now as it was. Meanwhile, their engineers are aware of the problem and are working to resolve it. Personally, I don’t need any more than the above stop-gap. I have essentially the same problem, I think.

All very strange!I have experienced exactly the same problem. Have uninstalled and reinstalled and updated all software versions for both Mac & Skype still no joy. The app remains 'open' in the system tray however I cant open it.

This definitely happened following a system update to the first level of Sierra. High Sierra update didnt rectify it either. I can obviously use web skype but the app is more convenient and useful.
